radiator problem... water pressure.., help?

[miib14]

havent had any luck with either test...
went to atleast 9 garages.. all busy. but when i explained what was happening i got some different reactions...

afew said headgasket (early),

afew said thermostat and waterpump because its not doing it all the time and only doing it on boost,

and one said blockage somewhere..

one also said when you rev engine and hold top radiator hose, there was alot of pressure building up...

most of them said come back tomorow, so another night of thinking and worry....

Thermostat - is easy to change - can be bought literally everywhere as it's the same as the UK starlet - try to change it FIRST and see what's gonna happen! But as far as I know overflow of the rad bottle - in most cases is blown head gasket - How does the antifreeze look like? Is it crystal clear pink? or is it like a cappuccino?

Make a video - put it on the you tube! Would be interesting to see!

well i went out today and its fine now..
dunno what was wrong with it... seems to have sorted it itself..

this is what did to check if it was rising..
when car was warm..

on and off boost (stayed the same)

just hard booost

left it to cool down, came back after 2 hours and it had gone down to just below the red line

very strange

sounds about normal to me mate. will rise a bit when you boost hard due to it heating up and expanding.

i would fill her to the right level and see what happens
