I recently had a new thermostat fitted to my 2002 2.0 156. I was had gone a short run to check the coolant lvl when i noticed that tere seemed to be a thin vapour escaping from the dip stick hole. So i pulled the dip stick out only to find it giving of smoke/steam and the same vapour was also coming from the dip stick hole? :eek:

Now i'm no car expert but i'm fairly sure this isn't meeant to happen.

Any ideas? knowing my luck its something big :lol:

it's why your car is fitted with a carter ventilation... if your car is running hotter now, the moisture from condensation in your oil evaporates more quickly now.. how cool was your car running before?

The car was sitting around 50 - 70 degrees with motorway running and 115 in traffic. Currentl runs 90 motorway and 90 - 115 in taffic:thumbs:

I been thinking the same, but i've read a few people on here have had to give it time until it started working correctly. So this weekend i'll take her a nice long run someplace and see what's what :)

115 seems high, can you see the condition of your radiator? this could be causing excessive heat in the oil aswell...
I've checked the radiator for signs of corrosion and it looks ok. But if the temp continues to peak i'll get a garage to replace it, better safe than sorry.

Does it gradually rise to 115 or suddenly jump?

Did they change the temp sender? Not normally part of the thermostat when you buy buy it.

Also, lloks can be deceiving on the rads.

Run the back of your nail along the fins. If they crumble, change the rad immediately.

No crumbling on the areas i've tried.:thumbs:

The temp rises to 115, but quickly (did that make sense:confused:)

I'm wondering if you have an airlock in your system

Thanks for the help :thumbs:.

One last question, the coolant and coolant bottle are both scorchingly hot, this ok?

Sounds like you have the same symptoms as I had just before my rad blew a leak. I couldnt see any evidence of corrosion either until I took the rad out. It was on the engine side of the rad right at the bottom where I couldnt really see anyway. Fitted new rad (pretty straight forward) myself over two evenings - temp rarely rises above 50/60 on a run or over 75 in a traffic jam!

As for your original query around the smoke/steam from the dip stick. mine does this slightly after a long run - that said I know mine is burning some oil - roughly 1/2 ltr per 500-750 miles so I check and top up every 500 ish miles.

if you check your oil right after a drive it will be hot and there will be vapour coming out the dipstick hole. its entirely normal, unless there is absolutely loads of steam coming out.
