Awesome video! How did you get the specification for the amount of diesel per injector and pump? According to GM Testing Procedure they have you test this with vacuum applied to each circuit of fuel which I personally think is an inaccurate test
Agreed, I don't feel vacuum is accurate enough of a test. It was one of the injector rebuild vendors where I obtained the flow rates. Can't remember the specific vendor, but I remember seeing the specs in more than one place. My FSM alludes to a couple but it's still quite vague.
I Was quoted 2500$ to replace the rear main on my 79 caprice classic 5.7 350. I may try to do it myself after watching this video.
Glad the video was helpful and gave you the confidence. Thank you for watching. Mike
Those engines along with the 3.6L are complete junk. My 170,000 mi 2003 Buick LeSabre 3800 (REAL BUICK ENGINE) will run circles around those other engines. Still has the original timing chain and gears in it too!
This is information for those of you that have Aqua Hot or Hydro Hot systems in your RV's. I would like to share something with you and your viewers concerning the the electric circulation pumps. As you and many know the pumps that run the heating zones are very expensive. Our 2004 RV has the Hydro Hot system. The motors inside the pumps are brushless so the way they are made makes it east to disassemble and clean the inside where the impeller lives. Depending on the use of the system the Hydronic fluid can degrade and build up inside of the pump causing the impeller to stick, no flow through the zones. If that didn't fix the problem, here you go. And now for the big reveal. I found this on Amazon and believe it or not they work perfectly. RALBDX Auxiliary Cooling Water Pump With Plug Compatible With A3 A4 TT,VW Beetle Jetta Passat Tiguan CC Eos Golf GTI - 2.0T Engine Replace 1K0965561J $21.99. Look at the price! They are just about the same size as factory but the difference is the inlet and outlet's they are 3/4 inch. You will need to go to a hardware store and get reducer fittings and some hose to convert to the 1/2 inch on the original pumps. They come with a wire and plug to fit the connector on the pump so connecting to the original wire leads is very simple. I hope this helps someone out.
I assume this is similar to the SRX engine bay. How did u support the motor once u removed the passenger side motor mount?
For this particular job I had the engine supported from underneath using a floor jack. For others I've used a topside engine support while removing the engine mount.
If rpay more. Dou you get better.... Bugatti comes to mind! VW parts, price hiked...
damn, can you believe its already 2025?!?, can time just stop and give me a break lol
Excellent content. Thank you.
Without a doubt! Hard to find quality anywhere anymore. I try to do all my own work and by watching videos from folks like you and AJ there’s not much I can’t do. Thanks Mike!
Thank you. Yes, quality is hard to find these days, but it is out there. I appreciate you taking the time to watch and comment. Thank you. Mike
From the first video I watched from you I could tell you run a tight ship!
What was the old adage…..Cleanliness is next to Godliness….unless you work in the oilfield….Then we rebuild everything in the rain and mud !!!! 😅
Agreed AJ. My career has been in the industrial maintenance field and a clean environment is not always possible, but we try to keep things as clean as we can. However, there's no excuse one can country their environment. Thanks AJ.
Hello Mike. Thanks for your videos. I just watch this one and your RoadMaster Chassis maintenance one. Both are very helpful. We just bought our country coach and have not been in a trip yet and are pondering buying a Jeep. If we get a jeep we will definitely follow your lead. May I ask where you had your coach repainted?

Thank you for taking the time to watch my videos and congrats on your new to you Country Coach. Country Coach makes an excellent coach. You won't regret getting a Jeep as a toad as they tow so well, easy to set up and are so much fun taking off-road. Just remember what Jeep stands for; Just Empty Every Pocket. 🤣 We had our coach painted at Mike's Custom Paint in Bremen, IN back in 2017. They did a very nice job. Mike
How did you get the driver side stub out?
The driver's side just pulls out. There is a retainer ring on the internal splines of the shaft like most traditional transaxles. Use a prybar and lightly & evenly pry between the flange and the housing and it should pop out.
Will this cooler work with the ppe high flow manifolds? Or do you have to modify those as well?
I'm sorry, I have not used the PPE high flow manifolds and cannot answer that.
i have a case that needs welding is there a number i can call to get a estimate
Sorry, I'm not taking on any more work for the time being. I'm buried and trying to get caught up, but I appreciate the interest.
This video definitely helped me on my LBZ! Thanks! This job is quite doable with 1 person on jack-stands as well. Note: I did not need to remove the top diff bolt but instead just loosened it. That amount of drop was enough for me.
Where can I find the quad seals for the actuator rod?

What is the purpose of tightening the band clamp to 150 in/lbs, then loosening, tapping the halves together and then retorquing to 160? Thanks!
It is a sequence much like tightening a wheel bearing, backing off, then tightening again. Some FSM's state to do this on fasteners as a form of evenly distributing force by allowing components to "take a seat" while tightening to minimize the risk of uneven clamping.
I have watched your video several times and planning on rebuilding my turbo as well. I mechanic a lot and usta drag race so a turbo doesn't look like it rocket science. I have another question. I've seen a video where a guy squirted oven cleaner in on the exhaust side to clean the vanes and unison ring. There isn't a taped hole for access. He drilled and taped one but not disassembled. I would not do that. But it could be done when everything is apart. This could be of benefit in another 40 to 50k miles. I'm interested in your thoughts.
I have heard of people drilling and tapping a hole to do just that. However, personally I don't feel that is the proper way to clean the carbon from the vanes. In my opinion the issue is more about the lack of clearance between the casting and the unison ring more so than the vanes themselves. By adding some clearance to the unison ring this issue will be less of an issue down the road, once the carbon is mechanically removed and the vanes and unison ring freed. If you choose to drill and tap a hole during the rebuild process then feel free. If I ever have the turbo carbon up in the future, I'll just plan on a repeat cleaning process. Thank you for taking the time to watch. Mike
@zmotorsports62 yes I am planning on a complete turbo tear down and cleaning as in your video. While tore down this is when I thought about tapping the hole. As in your video you joked about driving your truck like an old man and not hot rodding it to clean soot build up. I am 72 so most of my hot rod days are gone. Problem is after the rebuild, I'll probably still drive the same. I do plan on clean (polishing) the unison race as you did. I still don't know why this isn't a machined surface. Thank you for your response.
Thank you for posting this video! I didn't see the outer metal "crush" washer for the housing perimeter, as there is on LML's. Did you have one in there? I cannot get my to seat, let alone "fall in" place...OMGawsh how did you accomplish that? . I have lined up the pin and the actuator lever properly with the unison ring and I am banging with a large brass punch and I cannot get the halves to fit together! I am about to loose my mind. I have copper anti-sieze on it also and still not coming together. Any advise!?
I do not recall any crush washer between the holdings.
Fantastic tutorial on the subject…thank you! I have seen some folks frown on jacking up the motor by the balancer stating that you can “bend” the crank snout. Would you recommend on jacking up the motor by the oil pan and then resting it on blocks or is the balancer more than sufficient at handling the load? Thanks again for the fantastic instruction.
Using the balancer is fine IF, there is nothing restricting the engine from easily being raised. You are basically tilting it with the pivot point being the transmission mount. It's when people forget to disconnect something or there is something binding and they continue to crank up on the balancer. That's where the damage comes from. Thanks for watching and for commenting. Mike
@ Makes a lot of sense…thank you! 👍🏻
@johngreen2510 you are very welcome. Thanks again for taking the time to watch. Mike
Nice job mike
Thank you.
My name is Ernie and I really like your videos. It's refreshing to know someone out there knows a lot about the roadmaster chassis. After 30 years I finally got a monaco Windsor roadmaster. Its a 2003 and in very nice shape that's why I bought it. It does wonder on the road was thinking of putting a center steer shock on. Do you think that could fix my problem
Thank you for the kind words Ernie . I know a lot of people that put the center steer shock or steering stabilizer on their Monaco/Roadmaster chassis, however, I feel like they are merely a Band-Aid or masking the real issue with the Roadmaster RR8R chassis. It would take too long to go into the real opportunity with the RR8S Roadmaster chassis. Although it is a great chassis, it does have one inherent issue, and that is with the control arm vs. panhard bar placements. You could also look at putting the Atro bushings in the control arms, but I really didn't notice any great difference. There is an entire thread on irv2.com pertaining to this subject, but the short answer would be to look into a product called the Monaco Watts Link. Although my coach is on the Roadmaster S-Series chassis (tag axle) which aids in handling tremendously, I still fabricated a Watts Link for mine about 10 years ago, before they were commercially available and it made even a slight difference in how well mine was handling before. I have a couple of videos on my channel pertaining to how I fabricated and installed my Watts Link and gave a brief overview of how it works and what it is intended to correct. I've had mine installed for about 10-years and approx. 50k miles and at this point I would put mine up against anything on the road as far as handling characteristics, even the top tier coaches. Thanks for taking the time to watch and congratulations on your Windsor, they are great coaches. Mike
I agree that center steer stabalizer is a bandaid but I inherited it so ill use it. I also thought of making my own watts system and see how that works. Apparently according to the build sheet I have a RB8S chassis which I think is the same as a RR8S
Hi, Just did my rebuild and having issues. Turned on diesel switch inside and light comes on for a while but burner does not kick-in and then inside light goes out. You mentioned purging the fuel system. I've looked and do not see a procedure for purging air out of the fuel system other than a suggestion to try turning on the Aquahot multiple times so see if that corrects the issue. I did not put a fuel gauge on the pump, after the rebuild, as it is my understanding that the factory sets at 145psi. Wondering if the process of forcing fuel into the fuel guage might correct the no start issue, if indeed having air in the fuel lines is the issue. Thanks for any thoughts you may have.
I suggest you go online and grab a copy of the factory service manual for your specific model. Pay specific attention to the sequence of operation to determine where in the sequence yours is failing. When these units power up calling for heat, it is the blower motor that actually drives the fuel pump, the fuel pump does not run independently. The blower motor comes on as a purge cycle and then the igniter will start sparking before the fuel valve opens. All this is timed perfectly and it's something is breaking down in the sequence it will fault out. If the blower motor is running, the fuel pump is turning UNLESS, you forgot to make sure the coupler was in place between the two. Yes fuel pressure is preset but it is also adjustable in the event that it is low or high. It is hard to diagnose remotely but make sure you have spark. You didn't mention anything about spark and if the blower motor runs fuel pressure comes up and there's no spark it will time out and default.
Hi Mike. I loved this video so informative. I know you did this project quite a while ago but is there any chance you could link in all the part numbers in your description? It would be SO helpful as I’ve decided to try this project. Don’t have a fancy angle Torque wrench but I’m going to try and use a 360 protractor and mark it at zero and 105 degrees then torque to 74 lbs feet and mark where the zero is on the engine then torque till the 105 degree mark lines up with the mark on the engine. Can’t justify the 1900 wrench for one project . Thanks so much for your awesome videos.
Part #'s added to description.
@ you’re awesome!!!!!
CONGRADULATIONS on the accolades from BANKS, vert cool, i think i can do this thanks pump change.
Thank you very much, the interview and write-up was very much an unexpected surprise. Glad the video was helpful, the water pump replacement is pretty straightforward. Thanks again for watching and for the comments. Mike
Great Video! I've watching multiple times to make sure I'm doing the rebuild correctly. I do have on question regarding the mounting holes on the brass tower. I received a new part and the holes are not threaded. Wondering if Aquahot wants the screws forced into the softer brass to make the threads or if the part should have come threaded. Do you remember if your new part came with threads? Thank You
I'm sorry, I cannot remember if it came threaded or not. But I do not recall having to force threads into anything. Thank you for watching and glad the video was helpful. Mike
Well done sir! You have answered so many questions on what it takes to service these units. Truly appreciated and based on your other videos, shame on Monaco for burying a component so deep that requires continual maintenance. This is something I will look for if we ever move into a coach that utilizes this heating system!
Thank you for the kind words. Glad to hear that you liked the video as well as others. Mike
No rtv on the seal corners?
No. You can but I generally don't. I will add a very thin film of sealant to the bearing cap if I notice any scratches or gouges in the mating surfaces.
They took the key-way away now splines that wear out when bolt is lost.
How much is that job??? Where you located
Not sure how much that would run off the top of my head, this was my son's truck. I'm not taking on any additional work at this time, but thank you for your interest and thank you for taking the time to watch. Mike
Thanks again, ( 2001 Holiday Rambler roadmaster chassis) for your help on coolant, now I have an air leak passenger side rear bags going down over night. Found leak what looks like the dump valve there are four lines going to it, and it's larger than similar valves near it. The line that is leaking has a line that won't tighten, just spins and leaks at the joint, never seen a line like this. Any idea what type of line, it's the only one like it on the valve.
Sorry, I can't picture what line you're talking about. Maybe a swivel fitting is leaking? Glad the video was helpful. Thank you for watching. Mike
@@zmotorsports62 Thanks, I'll have to send a picture to a diesel shop, it's common but not knowing what the unit they go into is the problem. I'm assuming it's a manifold for airbags.
Hi, just bought the same rv 2003 monaco. the shop just change my trans oil by dextron atf fluid dex-merc is it good or wrong ? and the put shell spirax s4 ax gear oil in my diffenrentiel
Congrats on the coach. I can't say about the Shell Spirax as I am not familiar with that fluid. I would look at the manual for your particular coach as Monaco did use Dexron III in some models. However, starting around 2001/2002 model years, generally in the Dynasty and up they put Transynd fluid in the transmission. Transynd is manufactured by Castrol but more importantly is the oil's classification. Anything TES-295 or equivalent will meet Allison's recommendations. There is now a new Allison classification of TES-668 that will also work as it is reverse engineered to be compatible with TES-295. Hope that is helpful and thank you for taking the time to watch. Mike
@zmotorsports62 just asking. I have to put my trl brake controler. Did you know if we have all the wires somewhere in front or i have to pass 2 (blue) wires for back to front. Don't know where i can find exactly
@foxychevy Monaco/Roadmaster on later models ran wiring for brakes from the rear to the front. However on the older models (<2005 I think) they only ran a few small gauge wires from rear to front, not large enough for carrying brake current. I ran a 10-gauge wire for mine as I ran multi-axle trailer brakes with our race trailer. They did run a couple of 3/4" rigid pipes along the frame which are nice to run wires in and keep them out of harms way, however you have to hunt for them as they're usually covered in spray foam so locating them can be fun.
This is great! Do you have anymore videos on the 4th generation Acura TL?
I'm sorry I don't. I did a complete timing belt, water pump and tensioner replacement a while ago on the wife's TL but didn't record it. I appreciate you taking the time to watch and for the comments. Mike
@ Ok I understand. And I hope you release new videos on this great car in the future. Thank you so much for the upload.
i pulled my injector out and i did not see the washer. i panicked and thought i dropped it in to the valves and cam. i couldnt see it with a inspection camera, but then i thought maybe it bounced over to the next one xD im about to pull the gcover off to look for it, but then you said the copper seal could ERODE AWAY? could this be the case?
It's possible, but it's better to make absolutely certain. Make sure to check that it isn't stuck to the underside of the injector as that is quite common.
@zmotorsports62 im 100% sure the washer is gone. Did not hear it drop, but yes i probably should open the valve cover to be certain 😑 lucky me working outside in 12,2 °F 😂
Love your content. It would be fun to meet you someday. I live up here in Cove, UT near Lewiston.
Thank you. Yeah, you're not very far from me being just up north of Logan. The video you are referring to of my PM1340GT lathe, was one of my first videos over ten years ago and in my old shop. Mike
26mm roll pin was too long and would bind on the gear. My pin was spiral and fit tight so i reused it. The new quad rings made the plunger really stiff to move in and out hopefully that is normal.
You have to trim the roll pin down to the same length as the original or it can interfere. Yes, the quad rings will add some resistance, depending on how badly the original ones were. I've rebuilt multiple of these since and use the exact parts I listed without any issues. The roll pins and quad rings are not available through OEM so have to be sourced elsewhere but they work.
h i cool video. i have a question on the isl engine. where is the oil pressure sensor located
Thanks. The oil pressure sensor is down near the starter motor.
@@zmotorsports62 do you have to remove the starter to get at that sensor. things are real tight there
Yes, if memory serves the starter needs to be removed to gain access to the oil sensor.
If you have a stick shift, it is possible to change without removing the fender guards- just reach in the engine bay. Just need to pull off the last spark plug lead. Rocking to loosen the last bolt helped. It is possible using a stubby 10mm ratcheting to take off/tighten the lower bolts. You're doing it blind but it saves a lot of time. Being in Australia it is RHD- not sure if it makes a difference [ie. easier]. 2008 JK Unlimited. Made the mistake of a non-Mopar first time around - threw off a range of bizarre codes.
I really miss the way cars used to be made I don't need all this shit technology these new engines are crap
You only changed the bearings on each spindle. Why didn't you change out all the rest of the guts including the shaft also?
I only changed the brains because there was nothing wrong with anything other than the bearings. I now have just over 225 hours and still going strong.
@@zmotorsports62 Do you have to have a press to get the bearings to go in?
Not necessarily. You can press them in with a simple vise. Worst case you can drive them in with a drift and hammer but I don't recommend hammering in new bearing to install them as you can actually damage them. If you do drive them into the bore be sure to only hit the outside race.
Hey Mike, Just re-watched this video. Doing my Hydro- Hot service in the Country Coach and needed a refresher coarse. Thanks again for making these videos. I don't have any problem diving into a project without ever doing it before but when a guy finds a video from a master mechanic like yourself it's time to pay attention!
Thank you for the kind words. Glad the video was helpful and thank you for taking the time to watch. Mike
The engineers that built these are idiots. Gotta split the diff to change a seal 🤦🏻
gracias a dios llego bien mi compa solo una pequeña recomendacion piedras negras es la mejor opcion yo viajo mucho solo paguen sus impuestos y todo estara bien dios les bendiga
It's been 10 years, how's the lathe holding up? Any upgrades or repairs?
Is there a seal on the actuator arm that moves the unison ring? I put back together and I remember thinking the oil goes in and no seal was there. Now turbo blows oil out exhaust
No seal on the actual arm, there are quad seals on both ends of the rack gear which seal off the oil from getting to the arm.
@ yes I replaced them and roll pin and just didn’t see a seal and just wondered how it doesn’t leak oil
This video totally rocks! We are currently shopping for a coach, and this is an awesome prep video to evaluate care and maintenance by previous owner prior to purchase. Thank You Sir!
You are very welcome. Glad it was helpful and thank you for taking the time to watch. Good luck on your search. Mike
Mike. How do you tighten the belt for the A/C compressor? 2001 monico with cummins ISB300 engine.
Loosen the pivot bolt on the compressor, then loosen the fastener on the slotted adjustment and tighten to spec. then tighten all fasteners.
