9-3 2006 2.0L T Coolant loss

[rdodger]

Hi

I say coolant loss as I can't find an external leak.

I have read all sorts on the tinterweb but can't find an answer.

I have changed the header tank and cap, also pressure tested the system and found no leaks.

It still uses a tea cup full every 500 miles or so.

Any ideas?

Cheers

On my 9-5 MY2000 it came down to the seals between the rad core and the header tanks weeping when it was hot.
Presumably differential expansion/contraction does for them eventually.
A new rad sorted the problem - cheap enough on fleabay and not too difficult a job to DIY.
HTH.
Cheers. Pewe.

Thanks for the reply

On my 2.3t there was a rad leak, fixed that and it moved to the thermostat. Fixed that, all good.

Good luck chasing it down

EFA: fixed that = replaced.
