Bubbling coolant!!!

Hi all,

Im fairly certain i know the problem, but im a strong believer in second/third/forth etc opinions. So my jimny has started using coolant and has got bit worse.

Have bleed system etc, had fair old look about for leaks and no sign.

Symptoms are, using coolant, and i can hear a bubbling, it only seems to happen when i turn the car off and only for few seconds. It doesn't over heat and there is no sign of steam from exhaust. Oil is fine.

So what's ya thought peps?

Very grateful for any input.


Bazza.

what dose your temp gage say and check your rad if you use it off roaf it may be full of mud i had this untill last week so i changed my rad now its fine

The obvious conclusion is headgasket but I wouldn't jump to that conclusion too fast.
Like Mudman says If the rad is blocked up with gunk this could happen too.

Thank you chaps.

Was leaning towards head gasket. But can't be arsed Hahaha.

So if rad is blocked up would do same thing??

Temp gauge is fine sits bang on in middle and stays there.

Pressure cap not sealing properly??

What is happening at the overflow tank? Is the coolant on the mark when cold? Where is the level when hot?
