Zafira billowing out white smoke

Thank you will get water checked tomorrow and sort out the thermostat.

Again thank you for your help, my boyfriend was always surprised it didn't run as hot as his car and seemed to think that was a good thing.

The other possibility could be the turbo. They can smoke but normally it's blueish when the seals start to go. Normally around 50K miles. Maybe worth looking at that at the same time though.

It is definately not bluish smoke but as you say worth checking. Thanks, Nikki

When my turbo went it blew a greyish white smoke when I let off the revs. It did this in the morning and on the way home it blew a smokescreen that James Bond would be proud of and promptly died. BTW if this happens, switch off the engine and do not attempt to restart or drive home or your whole engine will be toast from bits of broken turbo and oil starvation.

Check your brake fluid level.

Maybe you need it.
The fluid leak is from the servo, through the vacuum pipe to the inlet manifold, and then into the combustion chamber, It's rare though, but not unheard of.

Leave the Stat alone....

I'd say 80ish on the temp gauge is about right for a Z20LET Zafira... 92Deg stat on these IRC. My Z20LET Astra ran at just over 80 constantly.

It's not uncommon for the vauxhall running temperatures to drop with age. They're supposed to run at 90c, most drop to around 80 eventually. Causes overfuelling as the engine is cold. The thermostat is one of the few things I've had to change on my 1.8.
As stumpjumper says though, get the turbo checked out.

With a Z20LET *GSI* which the OP has the cold start mapping code in the ECU which will allow overfuelling on cold start up starts to even out at around 52degrees... Can easily see what it does on when hooked up to the computer and can see all the Livedata... So theres is huge margin before lack of coolant temps start to cause overfuelling day to day...

For a Zafira GSI I'd say 80ish is around right.
