whats the best way to flush your radiator ? ever since i bought my rs turbo its had a overheating problem its had 2 radiators as the 1st one burst new thermostat but still the same goes into the red very easy if its not radiator what else could it be ?

 

Headgasket could be on it's way as far flushing the rad take the pipes off and use a hosepipe to flush it

 

Yeah hows the water? and white shit in there?

Fans cutting in alright?

No leaks?

 

mines averheating at the mo aswell, worse so after a run where i've bin boosting alot.
i've flushed the radiator and fan cuts in etc- sounds like a similiar problem to you

 

defo headgasket if you done to rads you not got an alloy one on it?

 

fucked water pump?

 

had this when the header tank developed a small leak,

splits around the seam

 

sorted it was a blocked water pipe that goes behind the head

 

mate ,get some radiator flush and pour it in
drive 100km and remove the top and bottom rad hoses
shove a hose into the top with a cloth around it and flush
stop when the water turns clear
