90 degrees

flicking through the ebay ads for 147's to possibly replace a mondeo with a cutting out problem, I came across one where the seller says he has replaced the thermostat as in his experience they always go faulty and now the temperature is "where it should be at 90 degrees".

Really? My 156 doesn't get anywhere near that high! It zooms along well below and is very happy. The only time it got up to 90 degrees was when the oil had got low. Is Mr Ebay seller correct or not and do the thermostats always go?

update - I have done the long M1 journey twice now and no sign of the dreaded motor controller unit system failure which was due to a misfire on cylinder 4. (Cleaned the oil spill out of the spark plug hole and fitted new spark plugs).

well after forcing a garage to replace the thermostat because they said: 'no sir they are meant to be like that'
well, my MPG improved a great deal! the car seemed to run a bit nicer too but that was probably just the effect of having more money in my pocket after the MPG improvement!

they did state the gauge was just slow, a couple of garages did. I ignored them and was happy I did. One was my trusted indy! that's the only time he's been wrong though

On my last two, the car guage sits so the needle splits the 9 in the 90. Fans come on as the needle splits the 0 in 90. It's worth the dough to replace the stat as it is an easy job and gives solid benefits.
