COOLING SYSTEM

2003 Subaru Forester • 130,000 miles

After driving my car for sometime and then you open the bonnet you realize that the coolant container is full to the top and the coolant is boiling, after the car cools down it returns to normal. Note that the temp gauge is at the right time always.

With the engine cold, remove the radiator cap and start the engine. If coolant shots out, you have a bad head gasket.

Check the radiator cap, seems it is bad.

Tried to change the cap but its still the same, tried also to remove the cap when engine is down then started it en there was very little over flow of the coolant but it did not gush out

Ensure cooling fans are working correctly.
Is the replaced radiator cap of the correct specification?
Ensure the cap contact areas are clean and good.
