[Lukezen27]

sounds normal.
Wat coolant are you using? Its not the cheap stuff isit? cos i rem that one my sister's car the cheaper coolant was the problem.

Na its Castrol good stuff

Check overflow siphon in bottle for any small holes.
This can cause same problem.

do you mean the rubber hose bit inside the overflow bottle might have a hole TODA AU?

Yup... That's what I mean.
If this is the case, the coolant cant be drawn back.
Or if the hose is missing.

Bare in mind, this is only a guess as to why the problem exists

Do you have a blockguard or aftermarket sleeves in the motor?

The rubber hose fell off when checking so I turned to round and now it fits far better

Drive to the shop and some coolant has gone back into the radiator

Do you have a blockguard or aftermarket sleeves in the motor?

Nope completely stock motor

Jimmy's Test Complete:

Bit of pressure when I opened the cap but no coolant came out, I've opened it before when really hot and only a bit came out that time... good or bad?

ive just noticed the same prob in my car, car temp gauage normally sits just below half way all yr round, but lately like in the last week its been sitting above half to 3/4 high.. but it does drop abit when im moving.

ive opened it when it was just warm and no coolant came out, but opened it tonite after driving normally (no boosting) and it blow up everywhere.. i have a feeling something is farked

try doing the simple things like changing the cap, thermostat, coolant and the pipe like Luke did. May solve your problem.

No! your quite right..

You need to follow Jimmys test as per this post

FYI

There might be a small leak from headgasket pushing gases thru the cooling system. This can be cause thru detenation. As i said i was in a similar situation and learnt the hard way by changing thru 2 head gasket only finding it wasn't the issue it was detenation and cause the head gasket to leak.

The added pressure is there which cause the overfill bottle to fill up, and not return to the system.

Here is a simple test. When cold start up the car, lets say 2-3min. turn off and remove the radiator cap. When you relase pressure cap if abit of coolant comes out thats seems normal, but if a shitload of coolant bursts out then you have a headgasket problem.
