Antifreeze smell...Where to start looking ?
« on: September 06, 2018, 11:03:38 AM »
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.

Check the heater core if there’s no visible leaks outside

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.

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.

Do you see any white smoke on startup or while running from the exhaust?

No smoke in exhaust on start-up.

Visual look for leaks, if none found pressure test it.
