Antifreeze smell...Where to start looking ?
Nufy:
Noticing a faint smell of coolant when my sons TJ is running.
Both inside and out. Rad levels of coolant have dropped as well over time but I can't say how much.
I assume it was full when I bought it last fall and a few weeks back I had to add about 1-2 litres to the rad to top up the level to the rad cap.
No visible leaks anywhere, no pooling etc...
Just wondering where are the common sources of leaks for a 2005 TJ 4.0 L 6 Cylinder.
Thanks.
Vinman:
Check the heater core if there’s no visible leaks outside
MattMan:
I concur with Vince...
Kanueh:
If no visible leaks are found either get it pressure tested and/or get a head gasket leak detector. Basically tests the coolant for exhaust.
Nufy:
No coolant in the oil as per the last oil change a few months ago...
Seems to be more from the engine bay than the interior...
Might run it up to temp tonight and take a flashlight in the dark to see if I can see anything.
