Right i have posted on here i think my HG has gone but i cant see how it has as the HG is the thick steel type which is new.No water in oil sniff test ok b ut got high pressure in top and bottom hoses.
Also ive noticed today while tinkering with it that i can hear well best way to describe it is "like a kettle boiling" noise coming from my filter? what the heck is that all about?

As for the HG issue what are your thought just want to be 100% sure that it is gone before i strip my beloved scoob.

cheers

Depends on your symptoms. I assume you have invetigated the other possibilities?

 

Try bleeding the system before you strip it. The noise you hear could be an air lock.

If i was you, i would drain the system and then refill as per the methord found on here. Do a search for "air lock" (include the quote marks in the search field). There are a few threads with the best way to refill.

 

Yep done evrything but is this bubbling noise related to my troubles?

 

could be an air lock as suggested.

 

my mate had same problem could hear bubbling, was told to start the car from cold remove the rad cap and it should take about a cup of water to fill it to the top, put cap back on job done apparantly its common fault
