Asked by 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?

Sounds like you didn't put the cap back on securely or the cap itself is bad. Also, check for a damaged filler neck on the radiator. HTH. -Jim

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.
