Coolant leaking out of the radiator cap. 4 liter engine.
625

Asked by Thorin Oct 25, 2016 at 10:45 PM about the 2003 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I don't know if the cap is just bad or something. It
didn't start leaking until I took the cap off to check
the coolant the other day. If I take the cap off and
run the engine it's starts go run out of the filler
neck. Could this be a head gasket or something
else?

Does coolant only leak out when the cap is off? That's normal. If it leaks out when the cap is on, replace the cap.

    Leaking antifreeze from beneath the radiator cap. The leak is not from the cap. The leak is coming from the end of the plastic cap under the cap.
