Driving round on these cold days, I noticed the water temp on my 1.8 16v was milling around the 80degC mark... is this normal for a cold day, or should it still be around 90degC, meaning my thermostat's a bit rogered?

And was it ever settled about whether the thermostat on a 16v engine could be replaced seperately (and cheaply!) or whether it was in fact cast into the centre of the engine, requiring a complete new engine? ;)

My temp has dropped to around 80ºC aswell. I replaced my stat about 18 months ago so I think it's still OK (or should be). The stats are a one piece setup requiring a complete new engine, gearbox and suspension.....not to mention the new brakes and tyres that are also needed to replace the stat ;)

Could be 'cos its colder at the moment, recent replies seem to be saying that anything from 80 up was ok.

btw...Marlon, sorry you're wrong, the 16v thermostat involves changing the majority of the chassis and front body work which is attached to the engine .....get rid of all this and access is easy :p

If it's so much work to change the stat wouldn't it be easier just to give it to MT and buy another one :D :D :D :D

You have a good point San...sure you could probably buy a late 8v for the price of a 16v Stat and save yourself the trouble in future......hows that :D

Debs, it's on the left hand side of the engine (as you look at the car from the front). It'll have a big black hose going into it, and one coming out. It'll also have the temp sensor screwed into the top of it which has a blue plug.

Err.....its actually on the right hand side of the engine as you look from the front of the car. The 16v has millions of hoses coming off it (well, about 8).

Mine sits about 70 in this weather :eek:

And the Silverstone sits at 90 (just had new thermostat fitted) :D but i think the water pump is well worn :( more expense :rolleyes:

Mine is the same, Speedy. As soon as I hit the motorway the temp drops to somewhere between 70 and 80. In town it climbs back to more normal values (85 or so). And it's on a new water pump and thermostat (and don't forget to remove the plastic plugs from your shiny new thermostat before fitting the hoses... Amhik... Or rather, don't ask). So I suppose the sensor just picks up the cold from the air blowing into the engine bay.
