hi guys.

Need a bit of help here.

when i drive my ca18 normally my temp is normal. as soon as I start boosting a lot or driving a bit like a mad man the motor starts getting hot,
when it cools down i need to replenish with about a liter of water, i dont see any water leaks and I have changed my radiator cap, I have even taken out my thermostat as well cause I thought thas was the problem.

any ideas??

Sounds like a leak, remember there is 11 water lines. Could be head gasket.

^this.

+ put your thermostat back
+ does the turbo blow white smoke? could be leak in or around turbo as well
+ make your sig pic smaller please

If you don't find any leaks it is probably head gasket.

If there no water leaks head gasket

Mine did the same and I found that it got progressively worse (up until the point of almost frying the motor). Turned out to be the intake heater pipe that runs from the intake to just above the starter.

the car i had also had the issue with that pipe, it popped off and i ended up doing the head in... :'( not so kiff i wont lie!
so id get it checked out before you do some baking of the internal type....

I like my pistons raw, not burnt

after i fitted my ic my car did it on boost at 140 starts to heat up drop down to 115ish cools down to normal
it blew out all water once from bottol over flow.
got radiator opened and cleaned at rad place there was about 30% that was not blocked.
after that never had a problem

I took her to Silverton Radiatord in Alberton, Did one of those chemical tests to see if there is a leak on the head, chemical stayed blue(when there's a leak it goes Green.

So, I replaced the thermostat, I also took out the little pin on the thernostat, I replaced radiator with another one I had.

Will be taking it on the highway tonight and see what she does

thanks for all the advice so far

so after 2 headgaskets, 4 engineering shops, new water hoses, lots and lots of time I am still sitting with the same problem.

hands in hair.

please, please help

If you have done all that, I think your problem might be in the engine block, I assume you changed your radiator cap?

Got a ca18 block for you

Radiator cap has been changed, i am now going against my will and fitting a new radiator with expansion tank

hopefully this will sort it out, otherwise either new block or new friggin motor
