I've got a sweet smell coming into the car whenever the engine becomes warm. Pretty sure I see a filmy residue on the windshield. My guess is that it's a coolant leak. I bought a pressure tester kit and hooked it up to the radiator. I pumped it up to 10PSI. I know the system can handle 18PSI, but I didn't want to run the risk of damaging the cooling system. After letting it sit for minutes, I didn't see any leaks underneath the vehicle. I pulled up the passenger side carpet to check to see if it was a heater core issue. Sure enough, there appears to be a red stain on the foam padding underneath the carpet. But the odd thing is that it wasn't wet. When the vehicle was sold to me, the vent shown in the picture was blocked with a piece of plastic Maybe intentionally to hide the coolant smell?

Going to order the heater core now. Log in. Im just playing.

After doing some searching on here I narrowed it down to a heater core going bad. Took it to a trusted mechanic because I don't have the patient or the time to try and replace the heater core myself due to how extensive it is on the wj.

I have a puddle of coolant on my passenger foot-well, all of my windows fog up, it was actually blowing what looked like fog out of my defroster which I'm assuming is leaking coolant being vaporized and blown into the jeep, coolant is slowly draining. So I went and bought a new heater core from the dealer and I've found a good set of instructions which i will attach. Is there another full set of instructions to remove that section? If anyone has done this or if you have any insight or instructions I would appreciate the help.

Once the bubbles seemed to go away, I revved the engine at RPM and held it for 30seconds did that a few times. This form of electrolysis is caused by bad grounding of an electrical component and can be a very rapid way of electrolysis, depending on how bad the grounding is and the current drawn. Did you have a repair shop do it or did you do it yourself and if so would you recommend others do it themselves also? I use an snap-on cooling system filler that pulls a vacuum on the system then uses the low pressure in the system to draw fresh coolant from the jug into the system filling all the little pockets and voids easily.

Happy to help and glad its all working out for you! Remove the bolt 7 that secures the heater tubes to the heater core 8. Fully loaded from factory so there's enough electrical in it to cause a problem already. They changed the unit 5 times and the hoses once. You have found the secret tip for turning a 6 hour dash removal into a 30 minute heater core swap so you are good there. Quote message in reply? I forgot to double check if the new unit had the seals in it already, I sure hope so lol. Once the bubbles seemed to go away, I revved the engine at RPM and held it for 30seconds did that a few times. I think that could potentially be normal discoloration of the insulation. Okay, if that is indeed coolant, it looks like it might be in a different spot than mine No need to mess with bleeder screws when using a tool like that. Mongo53 Replies.
