Nice, even if this is a somewhat temporary solution, it beats smelling coolant in the Jeep constantly 😀 If only Jeep hadn’t made it so difficult to change the heater core, we’d all be better off!
Even after you go through the trouble of the heater core replacement consider installing a bypass to the Core when it's hot out. Living in Texas I've found by doing so it makes my AC much cooler and haven't noticed issues with engine cooling by not having the fluid running through the core inside the cab of the Jeep. Come winter I just flip the petcock valve so the core will get hot coolant to run the heater. Once you do the PIA job of getting to the HVAC Box you will see the AC Evaporator is tucked right inside, next to and competing with the Heater Core when the AC is running. Maybe all HVAC systems are the same but I just didn't see that a such a grand idea. If I did have issues in major heat temps in traffic or trail riding I can just flip the coolant back to running through the core and let the AC Evap. give it a chill. I'm happy with the upgrade...
Yep! Have a 2002 Grand Cherokee same issue. I also dont like the puddle of antifrantifreeze on the passenger floor. Got my parts! Thank you for the part numbers and info on that! Doing this fix right now! I will NOT be replacing the heater core., Not worth my time and I live in the desert.
Just ordered the parts to do mine as well. Great video and thanks for the part numbers and the links. Def hate that smell and I feel bad for when my passengers mention it as well and it's strong.
Thanks for this video! My cousin wants to give me his '99 XJ. I noticed a strong coolant smell inside and I'm just assuming it's the heater core, which looks like an absolute bear of a job... If and when you do tackle that job I hope you make a video!
I'm putting it off for now :) There are a couple videos I've seen on UA-cam, but because it's such a big job it's tough to capture the detail of all the things that need to be removed! Grab that 99 XJ!
My plan is to replace the leaking heater core and then plug the existing silicone hoses back in at the firewall. I have the replacement heater core in hand, it’s just a monster job and I haven’t had a chance to tackle it.
For the hose and the connectors, would you be able to do this on a 91 xj? Or is it potentially different fittings? Ive got coolsnt directly leaking into my cabin passenger side and definitely need this bandaid stat lol
You should be able to bypass the heater core. Look at your existing heater hoses, they are likely of slightly different diameters. If so the fitting I am using should work. The hoses may be marked which would make it possible to be sure the fitting I used is a match. Good luck!
If you do the heater core also do the AC Evaporator. My Evap leaked and did that job and replaced the heater core at the same time. Didn't want to do that miserable job again. Good Luck
Are those heater hoses pressurized at all when the system is off and cool? Just curious if the grips would be necessary if simply replacing one of those hoses
When cold the system should not be under pressure. Are you asking if hose clamps are necessary? If so yes they are, there is enough pressure in the system when running that hoses will leak without clamps.
Matt's Garage & Misc. DIY thanks for the info. I was mostly curious if I could pull the hoses to replace them without having to drain the radiator. One of the heater hoses started leaking and wanted to wait until summer before I flush the whole system and replace the rest of the hoses
@@tbuckets007 I didn't drain the radiator, you'll lose a little coolant, but if you are careful you can minimize and top off. Ideally you'd bleed out any air that gets in too. Good luck.
That’s essentially what this is, but it has a nice 180 degree bend so that it’s nice and tidy. I’m sure there are other ways to achieve the same functional result, just sharing what I did.
Man , you don't have to take the hoses off the heater core or buy those attachments or whatever . Only thing you need is a short piece of heater hose and clamp it where the heater hoses attach to the engine . Of course you make sure to align the hose where it's not kinked and your done . Leave your hoses attached to the heater and zip tie them out of the way where they'll be safe . Done .
Randy, my ultimate goal is to replace the heater core, and put these silicone hoses back into full use. There are many ways to solve most issues, just sharing what I did.
@@MattsGarageMiscDIY I apologize. Sometimes texting looks like person has an attitude . If you had heard me speak what I said , I wasn't downing you . I apologize for the misunderstanding
@randybonner9870 no worries, I wasn’t offended, I do get some comments at times that are a bit more aggressive and try to remind myself that hopefully what I’m sharing helps a few people either decide to tackle a project because they see the level of effort or tools needed etc, or confirms for them that they need the help of a pro. But I stand by the idea that there are often multiple ways to solve a problem. Good luck with your projects!
@@MattsGarageMiscDIY Yes sir there are multiple ways and tricks . Best trick I've seen was if you have a bolt that you can't get in that most perfect alignment to get it started no matter what you do . Put the head of the bold in a vise and take a hacksaw and carefully cut 3 slits eventually space about a 1/4 - 3/8 deep . Man , I been there and you probably have too. I fixing to rip out my heater core . On UA-cam I typed in is there an easier way to put a heater core in a Jeep Cherokee. All the videos look the same . Freakin dash out , parts and pieces ,blowing out a good Friday night , all day Sat & Sunday till it's done hopefully.
@@MattsGarageMiscDIY I looked back at my original comment and it does look kind of pissy. But I wasn't really saying that or thinking like. Texting can get people in trouble because there's so many ways people can translate what it might sound like . LOL Like have you ever accidentally text the person that your beotching about thinking you sent it to this other guy ? LOL , " That Jim did a sorry job on that lawn " . Oh hey Jim , I was taking about this other Jim I know and blah blah back peddle. LOL Hava a good evening Sir .
Using a short piece of hose in the front of the engine is a lot easier than fooling around in the back of the firewall. Using the same principle of a short piece of heater hose in the back is a lot easier to use a short piece of heater hose in the front attached to where the original heater hoses were attached on the engine. You don't need to buy attachments or anything just put a short piece of hose at the front of the engine where the hoses originally attached
Plan is to replace the heater core and then reconnect the silicone heater hoses, so the “U” works nicely for this, but there are always alternate solutions as you suggest.
Thank you!! Helped us fix my jeep today! ❤

I like it. Will certainly give that a go in the future.

Glad it was helpful. Having a heater is luckily a luxury I can live without in my climate.

My hose was twisted, basically making a clog going to the heater core....would this be a reason my jeep overheats and my heater not work?
How come you didn’t just use the bypass on the thermostat housing and get rid of the blue lines completely?

What size are those blue clamps in the front holding them together? Thanks
They are Earl's 1" hose/tubing separators. I bought on amazon, but looks like blue is not in stock. Here is a link to red anodized: amzn.to/3f3okf7
@@MattsGarageMiscDIY thanks red actually works

where did you find the blue clamp that holds the two hoses together? Can you provide a link?
Dana, the hose separators are made by Earl’s, they come in various sizes and colors. Here is a link to the ones I used: amzn.to/3FSA3vb
Can’t you just connect the 2 hoses with one plastic 3/4 and 5/8
That’s essentially what this is, but it has a nice 180 degree bend so that it’s nice and tidy. I’m sure there are other ways to achieve the same functional result, just sharing what I did.
Did you disconnect any electric connection at all to by pass?
No, did not disconnect any electrical.
