Exhaust condensation

I get a fair bit of condensation from my exhaust, even when the engine is up to normal working temperature and I've just had the thermostat changed and it sits dead still just below 90. There's not plumes of the stuff but it's noticeable when I pull off at the moment (it's about 3 degrees here during the day) and isn't really comparable with other cars on the road.
I haven't monitored the coolant level yet but will be doing so after topping it up now that it has bled through after being changed.

Do I need to worry about the extra condensation or is it normal?

I reckon it's a combination of cold weather, and natural levels of worry about a car which is new to you.

I think this is quite common Andy - look for the threads with the word 'smoke' in them - what they mean is condensation

I drove Euan to school the other morning (usually walk) - outside temp was 2 & I could barely see out the back of my 156

Mine "smokes" like a chimney when it's cold, reckon i'm choking people behind me when I'm at the lights and engine is still cold.

Once warmed up she's totally fine though, but I know I need new maf/stat/variator/etc/etc/etc lol

Yup, the gf is always commenting, not sure why it creates more than almost all other cars, think the supersprint holds more water again after a wet night and causes even more.

I'll keep an eye on my water levels, but it must just be that the 147 exhaust gases get cold quite quickly as they travel towards the rear. After all; C8H18 + 12.5 O2 --> 8 CO2 + 9 H20.

Thanks all.

My 147 is a "heavy smoker" on cold mornings, has done this since new. Don't worry about it, as long as it's fluids are at normal levels it's one of their "special" traits
