89 xj 4.0 closed coolling system....
Recently the collant started boilling in the coolant reservoir at about 195*-210* It only happens in traffic or sitting still.
The engine isn't over heating its just boiling out through the cap on the bottle.Is this just a pressure issue?
The cap has always hissed a little since I've had this jeep(4years) but never boilled out like this....I wonder why it started all the sudden???.Is there any way to test the cap?How do I go about pressure testing the entire system and how much pressure does it run at?
Does it sound like the cap is the problem and where can I buy just the cap?The bottle itself is not leaking.
I should mention that I was wheeling last weekend and wasn't paying attention(fans wired to a manual switch) to the temp gauge and it got as high as 260* before I caught it.So that could be related....
Any help is appreciated....Thanks.
Oh and one more question:How high should the coolant level be in the reservoir at operating temp?
