Possible air lock needs bleading

**SteveC200** · 13-05-2008, 07:05

Air lock or blocked rad at a guess.

Put up with it or get a bigger radiator.

is this common on a ca18det

**SteveC200** · 13-05-2008, 18:26

Only if youve got a blocked rad or an air lock.

There is another explanation but I dont want to scare you.

Two Q's:

Do the heaters work? What about when the temp goes in the red?
If you drive the car TOTALLY off boost, do you get the same problem?

Evan s13 · 14-05-2008, 00:36

yer it will happen at random times if you drive under boost it still does it the only other thing i can think off is i have a fmic could this be blocking air getting to the rad also the heaters work when on red but will go cold when it drops
thanks

**SteveC200** · 14-05-2008, 06:00
