Burnt Coolant smell after Boosting

[Guest Raynes]

Hey Team,

Latest problem with the old STi is after is been takin for a bit of a thrash it stinks of burnt coolant, if it hasn't been driven hard then it doesn't. Doesn't seem to be using a whole lot as I filled it up with water. Any ideas? No real smoke or anything?

Version 7 STI

there will be a leak somewhere, check radiator tanks for small splits.

Yea figured as much, can see this is going to be a pain to find haha

The last time I had something like this it was the turbo dumping coolant into the exhaust.

Pain in the a s s those coolant leaks I had hoses fail all over the car over a 6 week period. Just when i got 1 plugged another would come up. god they take some time to track down............process of elimination bro........be methodical

something we've seen a lot of here is post '90 radiators (manual ones particularly) going pop on the driver's side end tank, about 2" down from the top they develop a crack where there is a join in the tank material. this crack only opens under high pressure, so you probably wont notice it unless, like mine, it sprays the water out the gap between headlight and grille and all over the windscreen.

I'd get it pressure tested myself, I had the same problem with a TX3 Laser I used to have, if you gave it the jandal for a minute or two one of the radiator tanks would squirt a little bit onto the exhaust manifold, the pressure tester showed it up straight away, it's not overly expensive to get a mechanic to do it either.
