Technical The heat is rising after changing to a new thermostat.

[mechtech]

Hi everyone..
I've recently replaced the cylinder head on my punto s60, including the thermostat.
Before this the temperature was just above the quarter and now it's on the half mark.
My question is, what the cause of this? it's because the new thermostat or maybe the it's because the slightly narrowed water passages on the skimmed head or something?
The new Thermostat is A116 87degrees BEHTR 75891350.
In Haynes It's say that The recommended Thermostat starts to open between 85-89 degrees and will fully open in 100 degrees, should I change to another type?

Thank you in advance.

That sounds OK. Could be any number of reasons why you were getting a lower reading before. Do make sure you've bled the system well.

82 degree stats are available -- at least in Greece -- from Motorad, which might suit Israel better than the 87 degree ones.

Are the 82 degrees stats made for the diesel models?

It's a deisel?

Not sure -- I'd guess so, but it's only a guess.

Half way on the temp gauge is exactly where it should be so I wouldn't worry
