Hi all owned my 03 sti for 7 years coming up to 8 years first owner worked for prodrive and then me fully looked after hasn't been tracked more of a show car too add it's just turned 74k miles

It's never missed a beat ever

Yesterday on way to garage for cambelt change I noticed the temp gauage move slightly and thought I was tripping , 5 miles from garage I decide to put into 4th give a pull from 30mph to 60mph and the temp gauage rocketed up and over the red hot mark

I pulled over stopped checked all pipes for leaks nothing got all fluid still checked exhaust no water coming g fron there

Heaters still blowing hot and cold air

Started car again and it stayed in the red until I arrived at garage

Is this head gasket ?

I have new water pump thermo and cambelt kit being fitted

Never ever missed a beat and the day going to the garage it decided to mess me around

 

stuck thermostat? cant see it being headgaskets with a 2.0. and well looked after. hopefully the garage can give you a better idea once they strip it down

 

I hope its just thermo or coolant sensor something simple

Just wanted to post up here and see if anyone with same ej207 had had any similar issues

Just my luck all these years and on way to garage decided to mess me around

now it's on my mind

 

does the rad look ok? no corrosion or anything

 

Yeah rad is all good looks pritty much new had all coolant hoses and header tank replaced 2 years ago with samco hoses
