Antifreeze/Coolant Smell but no leak...

Hi all, hope everyone is doing well.

For about the last 1 month I smell antifreeze whenever I get out of my jeep. I have been consistently checking and there does not appear to be any type of leak (no pools or wet spots under the jeep) and additionally, the jeep does not appear to be losing any antifreeze (it has maintained proper levels without addition of more fluid).

Any idea what may be causing this?

Any advice is appreciated!

Thanks,

ben

You most likely have a very small leak that only leaks under pressure and is small enough that it burns off rather quickly. I would pressure check the system and look very closely at the seams between the radiator core and tanks. Pressurize the system to the cap's rated pressure. Also test the cap.

My RHD TJ - Savvy equipped... And loving it!

I drive on the right side, what's wrong with you?

alright, thanks for the help!

Probably a pretty dumb question to most, but how does one go about pressurizing the system to the caps rated pressure and how do you test the cap? my guess is that by pressurizing you mean to have the jeep running and then check for small leaks???

I would check the heater core for a leak if you smell it when you get into the Jeep.

with a pressure tester, and i think autozone will loan you one. you could also look around the thermostat, water pump, heater hoses. noturmailman is probably right, that it is burning off before it shows in your driveway. when looking around, look for a white residue build up, that will help you pinpoint your leak. good luck dude.

Check the top tank of the radiator, that's where mine leaked for 50k miles before I finally replaced it.
