- This beautiful vintage Newell RV needs some serious maintenance done. A big project is this radiator that’s plugged up. Cleaning and rodding the radiator. New shocks, brakes, airbags, bearings, races, air compressor, air dryer, block heater etc.
Scott, it's really fantastic that bus owners can get honest and very high quality work done on their highway beasts! You and your son are examples of how to do things right! Great Video!
..faster up the mountain with a trailer than many without one!
That shut down knob should be a bright color....
Yes
I was thinking same thing.
In this day and age it is often difficult to find a repair shop that you trust, maybe just bad feelings about some. Yours is a shop I would trust although I don't have a bus and after watching your vids don't believe I can afford one. Enjoyable videos though. Thanks for sharing.
I use a marine product called Barnacle Buster. Last time I did a large radiator like the one on this Newell I built a tank to suspend the Rad in, 5 gallons of Barnacle Buster and the rest with water. A circulation pump for 24 hours. All clean, no have to rod it out. But you're the experts, I'm just an old backyard mechanic.
Amazing that these old buses can tolerate so much neglect and still bounce back!! $1K labor vs $3K radiator core = MASSIVE WIN!
Hey Scot, I have a mate that worked in radiator shop, he used a modified bandsaw blade to rod out his truck radiators.
Great content. Thanks from Australia.
Back in the day My dad had a Rad Repair shop. Once the rad came out of the Caustic Bath and was rinsed the kids had fun running "rods" through the tubes to finish cleaning them out. The last time I needed to clean a rad it was in my my 82 300 SD I put a CLR & Dish Soap Mixture in the Rad and ran it for 3 days. I could not believe the crap that came out of that engine. When I was done with a new water pump the engine temp stayed in spec and the care worked great.
I had a rad done on someone else's car back in the 80s. That was in San Diego. The next time, a few years later, I wanted one done, that shop was gone and I could not find a radiator shop anywhere in town.
Did they outlaw doing that because of the caustic chemicals? Or is it cheaper to replace most radiators nowadays?
Radiators with plastic tanks are not repairable.
Thats right - they are not. Back in the day for nme is the late 50"s and early 60's. As well, most heavy equipment and farm tractors contunied to have metal tranks well into the 90's.
@@wernerdanler2742 Between plastic tanks and the EPA, you can't find a radiator shop anymore. Let alone one that could boil out a crusty rad and solder up minor leaks.
For rods read clock spring must have done a few hundred in my days keep a hose flowing in the outlet and work from the top down.
DANG HE MADE A FAST PASS ON THE HILL WITH A TRAILER TOO
As someone not super familiar with buses I find the variety of cooling system designs kind of fascinating. Side radiators, rear radiators, axial fans, squirrel cage blowers....it seems like every manufacturer had their own idea of how to do it.
Don't radiator shops dip them in hot baths of acid to clean them any more? Probably not environmentally feasible these days. 😮😮
This is an entertaining video for an old retired guy to watch. Thanks for sharing.
I had never heard of Newell before, and I thought I knew a thing or two about RV's, buses, conversions, and auto mechanics. I looked them up, and they are still up and running today! I learned something today. Thank you!
Yes, and new Newells are close to $2,000,000.
Hand built custom coaches built in Miami Oklahoma from the frame up
Newell Awesome! ANytime i want to relax I come by to watch Scott and the crew. A big cup of coffee and Exhale.
Newell is really good about keeping records of old builds. Might be worth a call to see what info they have on that air dryer
I'll tell you an overheating story-
Once upon a time a trucking co bought a brand new simi. They placed it into
service and it gave them several years of good service. Finally, it clocked enough
miles to require a rebuild. The co rolled it into their shop & an in frame overhaul
was done. From the day that truck left the shop it ran hot. It was in & out of the
shop numerous times but continued to run hot. Finally, at about 50,000miles on the
rebuild the truck was in a major collision & the truck was totaled. The wrecked truck
was bought by a mechanic who was given the trucks repair & service records. He
bought it anyway. As he began to strip the engine to rebuild he opened up the
engine oil cooler & inside found a red rag. He removed the rag, re assembled the
engine, sold it for a nice profit & that engine returned to service for 700,000
trouble free miles.
!
I don't own a bus but I never miss one of your videos. All of your team are just good mechanics.
just think how that bus will be safe now that you guys have done the work. that should be a heck of a feeling for you and the crew, great video . kip
all my respect for leading a great life. You gots to be happy. Keep those uphill screamin sixes and eights coming this way.
Was seriously looking at a mid 80s not long ago. They make a nice coach and are one of the few still in business. In the end, the price went up and I was out. Love our LX
Always look forward to the bearing close ups.
Impressive! I'm referencing the cleanliness of the shop when there are no buses in it! The garage looks terrific and much better than the radiator tubes! We see lots of those calcium deposits in the water here, especially on the hot water side of the plumbing.
Man that’s one seriously plugged up radiator I’d bet it was never flushed out since the rig was built
the main reason of school bus fleet we had of clogged radiator and heater radiators is mixing antifreeze fluids , often causes motor overheat and non-operative heaters
That'll do it...!
That radiator flossing would kill my soul. God bless the person with the patience to do that. Must’ve taken forever.
I follow this channel because I am fascinated by the weirdness of North America. This idea of towing a box trailer containing a car just takes it to the next level! Here in Europe you will sometimes see a van derived camper towing a small car on a A frame but something like this rig would just be a nightmare to park or take through narrow streets.
Do you have garages for your cars to park in at home?
Putting a little commuter car in a box trailer saves on wear on the car and protects it from the weather. RV parks and campsites often have pull-through sites so large RV's won't have to back up.
@@BusGreaseMonkey I can speak for the Netherlands that most houses don't have a garage. People need to park their cars on the street and in the bigger cities like Amsterdam, Rotterdam and Den Haag it's problematic.
I remember the first time I saw you rod a radiator. My grandad had heavy equipment and taught me. He used packing straps.
That beautiful bus needs a lot of maintenance, but it climbed that hill like a beast! I would think you must be becoming known nationwide for your good and honest service. If I had a a vintage bus that needed work you would certainly be the folks to work on it.
Man you guys are it! Good old mountain mechanics. Your work ethic is definitely where it’s at. I like how you use your heads to solve problems and not a damn book . I have been a gas mechanic for years and done all my own work. I recently bought an old but pretty good shape rear engine diesel pusher. I went from front to rear on it and I found it’s basically the same as my truck only much bigger and heavier with less electronics. I really can’t wait to see another video from you guys it really does give me ideas. Keep up the fantastic work.
I sure like to say to the group you guys have a real nice garage great work for what you do a lot of hard work going and thank you for sharing the videos keep them coming
Need a big ol' tub and 20-30 gallons of CLR...soak it and see if it can break up that corrosion and stuff and save the ore...or just replace the core
Very cool...LOVE watching your wrenching on big ol' buses!!!!
Keep em coming!!!!
Scott, good move getting rid of that CR Brakemaster air dryer. Those units were really designed for use on trucks, where the unit was intended to be frame mounted so clean cool air could circulate thru the cooling fins. The condensate would be trapped in a stainless mesh in the bottom & then purged. They didn't have a desiccant pack like a Bendix dryer. That black residue in the hubs is most likely the result of adding dissimilar lube oils. Mineral gear lube & synthetic gear lubes do not work well when comingled. Keep up the good work!
Interesting video Scott, lots of work required. The clean out to the radiator will improve the efficiency greatly!
That's the exact same radiator that was in my 72' Maverick !!
😁
Them mavericks must have a huge motor in them! Haha…!
@@rustymullins6623 Oh yeah,,,,, it had a 302 with almost 130 horsepower !!! :)
@@2packs4sure lolololol…daddy had one with a little six cylinder…rode it to work in the coal mines for years…tough little car…
@@rustymullins6623 I loved that thing, it moved and would smoke the tires right off it,, wish I had it today !!
The only thing that ever broke was the A/C...
Hey man...its worth a shot....Plastic Processing Equipment has an acid that works GREAT con calcification. I have used it for industrial water to water and water to oil heat exchangers. Copper safe. Once the chemical is "used up" it becomes neutral amd can be disposted of as dirty water.
I know this job is long gone...but may getna 5 or 30 gallon jug of the stuff to have on hand. Caution: do NOT get it on your hands when it fresh. It will be very unpleasant.
Love your work keeping these old girls going.
Best way to use the stuff would be....leave the radiator intact....get an inexpensive electric water pump and circulate it right through the radiator amd return it back into the drum or jug. This is how I used it on heat exchangers. I could take a heat exchanger with almost zero flow and revive it back to new performance.
My 1991 Prevost H3-40 has a 235 gallon fuel tank, but 500 gallons is a heck of capacity.
500 gallons is a lot of weight to haul around! It gives them a... 3000+ mile range?! If you made your own bio-diesel that would be worth it I guess.
Every time I watch another video from your amazing shop, I think how fortunate we all are for the incredibly careful work you all do for bus owners and their families. Indeed, for all of us! A mere thank you seems way too little, but it's most sincere and given with the honesty that you exemplify! Be well, be safe!
Whenever I see a bus pulling in to your garage, carefully! I think of the navigation aid called a range marker. Its two vertical poles spaced apart such that one disappears behind the other when the ship is on course
Love what you and your viewer's did for Hank, I actually went and listened to his music, he's pretty good so much so I'd actually go pay to see him perform.
Scott, those 5/8 nipple heater valves are readily available and common as grass for semi tractors with sleepers, they are used to turn off the bunk heater flow, for summer time.
Never seen that style on a bus before.
I really enjoy your videos, hopefully others will follow guidance to do the job right, I twisted a wrench for 40+years on automotive, now retired and traveling the country.
You know, Scott, CLR has a radiator flush as a part of their Pro Line.. "CLR-PRO-Heavy-Duty-Radiator-Flush-and-Cleaner" might be worth it to get a few gallons.
Your son is always in there doing his share of wrenching. Teach him everything you know. Love the Grease Monkey song at the end of the videos. I listen to the whole song as it is so well done.
Another patient leaving in better health, thanks to BGM ❤️ ☮️ 500 gallon 😳 that's apocalyptic 🤏
Wow! what a difference in rad flow! Great work as usual! If you had ten bays you would be full of work. You guys put truck shops to shame! I have learned some things I was doing wrong on my tractor-trailer!
My Dad used a band saw blade with the teeth ground off to clean radiators.
Left one tank on and flowed water up with the tank at the bottom and water flowing upward in the tubes.
impressive work in a short time
Quality work and well documented for current and future clients. Throughly enjoy you videos.
Thats a pretty good looking rig there. As for the problems...the rodding out things you used I would never have thought of...before and after is amazing. I wonder how the water pump looks..hopefully okay. It's a bummer seeing sparkly oil from axles ...at least the bearings and races were not delaminating. Alot of work for sure but that puppy is gonna be running alot cooler for sure...I wouldn't be surprised if thats the first time the tanks had been off the radiator.
A great job and video as always Scott...you never disappoint:-)
As expensive as the big radiators are I would be wanting to use plastic/nylon too. Less chance of damaging the tube compared to a metal flat rod. Good job everyone ...
Looks like a lot of dirt in that that’s the overheating problem, for sure… you got a lot done in a few days nice job Scott …
a radiator guy i once spoke to used old cummings dip sticks sanded of blunt to rod out rad cores as they are long enough to go down all the way. with a mixture of salfuric asid and water 50 50 did a top job
You guys are amazing with what you do
Silicate mud! Modern coolants contain organic acids that passivate (coat) surfaces inside the cooling passages. It does take some running time on the engine for this protective layer to form, but once it does, extended coolant change intervals are perfectly ok.
Your attention to detail is outstanding!
I tried some barnacle removal liquid for engine boats and works great to unplug radiator calcárea deposits, followed by manually what you did.
Love the theme song for your show!
That has some serious squirt,took on the hill effortlessly with loaded trailer .👍
That’s a CR style air dryer in the bottom is a Brillo style filter is very easy to rebuild
No desiccant?
@@BusGreaseMonkey not that I recall undo the bottom and wash in parts washer . The unloaded kit is really simple also
Rebuilt. A few of them with great success
Excellent work.
Excellent job on that radiator!
Love those old Newells.
Great job guys, keep up the good work.
That is one hell of a radiator.
About the radiator cleaning it's the best way to have it horizontal and lett water go in from the top tank. The core outside too.. have 45 year off radiator service and have seen them before.. good luck..,👍👍🇸🇯
That's a beautiful bus, looks great!
That Rad needs to be Hot Tanked for 2 days!! Good Job
I built a stand for cleaning out radiators that has a small tub on the bottom of it with a small electric pump that recirculates diluted acid back up to the top and I let it run for a while before using a variety of stainless steel strips that I sheared to clean out the individual tubes that didn't clean out with the acid flush.
You guys need that stuff they use to clean air conditioning condensors to break down all the blockages on those radiators. People don't also realise that the thin brass concertina fins between the tubes can be all rotted away which makes the radiator 40% or more less effective, even though it looks fine it just deteriorates over time. I don't know where you can buy the brass material, but you get it in stacks compressed together and you pull it out into a V pattern before you install it in between the tubes.
Wow that's a lot of work ... impressive !!! Free hack for you on the Rad ... "CLR" is nice but not really effective without a lot of Elbow grease. Next time try something even better. Plug up the bottom with rubber pad (weight of the Rad should seal it up ok) and then pour cheap "White Vinegar" down all the veins and just let it sit overnight. The obstruction is "Calcium Carbonate" and the Vinegar will etch right thru it. Amazing stuff from my experience. Again, great job and enjoyable to watch. Looking forward to the next installment.
Wow what a big change
A flat oil dipstick would work well to rod out the radiator
I'd be scared to use metal in those tunes, as all it takes is one wrong push and then there's a hole...
you guys work pure magic!
Scott these Newell's are custom built coaches mainly popular in the NASCAR World......
Newell up in Miami OK as the complete build sheets for every coach they made, I'm sure if you were to reach out they could give you info on what you need!
Newell coach should have the info on the air drier....
I’m curious. What model year is this RV? I’m not sure if you mentioned the year, or maybe I missed it. I’ve never seen one of these before. It’s always very soothing to watch you reverse the aging process on these older buses and RV’s by repairing all the little issues which have arisen due to age, use, and sometimes even neglect.👍🏻
Look at the ROOM inside the shop now!!!
Consider running with out the grill. It causes turbulence that limits air flow on a pusher. 18:37
Just remember they're looking to you to help them & if not you who that's why we watch to see the angels in training God bless
Wow that is so much progress so fast. Good stuff!
Near the beginning of the video, you mentioned that this bus has 500 gallon fuel capacity. I was told a good many years ago, that if you carried 400 gallons of fuel or more, you had to have flammable placards on it. I urge you to check this out. The fine for not placarding is very huge if caught.
For weight purposes they don’t have both of them full at the same time.
I work on a lot of cars and trucks. Plus I work on small engine. I like the way you guys work together to get the heavy work load done. Team work is dream work.👍Buy the way the telegram is still contacting me on UA-cam.
The water running through the cleaned radiator looked the fuel flow through a top fuel fuel injector. 15 gallons in 4 seconds.
It was a heck of an improvement in flow. From Prius to dragster :)
Please invest in a harbor freight scissors type transmission jack. Doing radiators like that. I use it for automatic and manual transmissions on cars and pickups. But i also use it with a folded moving pad to support car and pickup doors. To change door hinges or the bushings.
@18:09 Need to make a 20 min clip of water sounds through a radiator for sleep sounds 😁
I did of a River flowing haha
You guys really get the doozies, don't ya!!!!
Love the old school Geo Tracker.
Am curious : Are all buses tested for 100% throttle ? I know there is that one brand that has that bit of carpet under the accelerator pedal. But, due to age and usage, is it worth confirming that each bus entering the shop is receiving full throttle ?
Like having part of the standard checkup experience be to have the DDEC ( sorry if i got the acronym wrong ) hooked up and numbers confirmed. Viewers might enjoy the routine, and the ability to compare various sensor stats between different bus models / age / mileage.
Thankyou for your content !
There's no radiator shop that could clean the radiator in your area? Lot of work that will keep that bus running right. Enjoyed the video.
Probably charge an arm and a leg & no guarantee they would've done it right, considering the previous situation with the country music star's bus
Nashville but two trips there and back is probably 5-6 hrs of driving alone plus waiting for them to get to the job days or weeks?? DIY
Thanks just wondered. Time is money.
Awesome hill climb!
Scot caustic soda unblocks the radiator you don’t even have to take the radiator out. I used to do it on my tractor all the gunge will come out from the drain plug leaving the radiator brand new.
The large earthmovers utilise those compressor aftercoolers
I wonder if a thermal camera would have been easier, showing hot and cool spots on that rad. That’s how I found that mine was blocked.
G,day men ,, the radiator cores looked better than I thought but I use a tri lock heavy duty cable tie and drag it back and forth turning to get groove to grind of calcium and compressed air back an forth both ways but don't let it dry out keep full of water 8f your not going to finish it , holly shit later in video you were doing my idea anyway,, Scott that means we are both switched on
Drain plug looked like the frontman for a punk rock band..
The radiator on my bus is right behind the back left wheel and because of that and no clutch on fan the engine bring in low gears revving at Max, the fan draws the grass seeds spider webs and dirt and dust and then water too from spray of wheels , well it blocked it solid, was Un able too push quality utilux cable ties zip, through it so I used tooth brush and compressed air , backwards forwards etc and the pieces of dirt acts like sand blaster and loosen more n more as you go , but still had to work bigger stones out , but in the end I got the lot out and not the fan really socks hard , warning to others with side radiator set ups behind wheels
At least that radiator won't rust,that corrosion is unreal,the blockages of the radiator,im surprised it didn't go nuclear at a half decent climb
Fantastic BIG job but when this bus pulls out it'll be "good as New".
Tyler's hammer blow ratio is 2 to 3. Strong! 🙂
We had ours record 4 years ago. Maybe 5000 miles on it. Hopefully years to go before doing this again.
Really a lot in 3 days. Gonna be like BRAAANEW!!!!!!
I like to setup a pump and circulate. An old sump pump works pretty well. Probably skip the CLR and keep some muriatic acid (HCL) on hand. ...works wonders on aluminum.
What kinda Muriatic dilution levels?
@@mrmotofy 4:1 Water to Acid is a good place to start for Aluminum/Copper. You can buy different concentrations though. Lactic Acid (Prime mover in CLR) might be better depending on your pump construction. HCL will eat Iron and Stainless pretty quick at higher concentrations although if you've got an old pump you don't care about and use slightly lower concentrations... it's an option. I've always used mag-drive pond pumps that are all plastic which makes it pretty easy.
