Let’s talk thermostat temp
Vadis calls the non-turbo out as a 90°. I really don’t think it much matters, the temp ratings are the point where the thermostat starts to open and the ultimate operating temperature is much higher than 90° or 92°.
“The ECT sensor was a BITCH to get out, I had to go buy a 19 mm spanner from autozone, I still don’t think I got it tight enough because the edge of the wrench rubs against the intake manifold but so far no leaks so I guess I did good. I guess that’s why it has a crush washer on it.
No codes or anything, temp came up nicely and looks to sit a bit lower, as I believe I had a 92C in there before but didn’t have it written on it.
Oh I also bought the new theromostat housing bolts from the dealer, $0.81 for both out the door, WORTH EVERY PENNY, they are made quite a bit stronger made out of a blackish metal. I also put antiseize on them.”

Sorry to drag this up again, but my coolant system is over pressurising on occasion so I suspect my thermostat needs replacing. I have an MY96 850 T5, but I am struggling to ascertain if I need the 87’C or 90’C variant. The general consensus in this thread suggests 87’C, but other forums with the same question seem to point at 90’C (though there seems to be no real justification for that recommendation). My manual states 87’C, but the local dealer pointed me at 90’C. I’m leaning towards 87’C, as per the manual and this thread, but they are rather harder to find.
I also understand the recommended brands are either Volvo or Wahler – are there any others to this, and does anyone have part numbers for the 87’C variants? The only P/M I can find for Wahler is 4272.90D, which obviously is the 90’C variant.
Correct thermostat temp for 95 850 N/A?
