Correct thermostat temp for 95 850 N/A?

Post by **wheelsup** » 20 Nov 2008, 17:18

FCP lists the 92 as the OEM for the non-turbos but I replaced mine and it makes the temp sit "just" above 3 o-clock by a mm or so. Thoughts? I can't find a definitive answer.

Is the 92 the correct one for a 95 850 N/A?

Vadis calls the N/A 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°.

Thank you I was looking some hard info from Volvo, I agree though 2C is very little, my guess is we are marking with a pencil cutting with an axe so to speak.

I'm replacing the ECT as well, and am replacing the radiator hoses, I will order a 90C one just to make me feel better and help me sleep at night

.

I searched several forums and I couldn't find it, I posted a response to my own question over at volvoforums.com as well so anyone searching (like me) can now find it.

Thanks again Ozark.

I dont think thats correct, 90 is the only one you can get from dealer these days.

I think it may be a typo on FCP's part. The exact same item number, Wahler 271664, is listed as 92 °C at FCP and 90 °C at eEuroparts.

OK to wrap this up I replaced all the hoses besides the lower radiator hose (that was done 2 months ago when it blew), the thermostat, and the ECT sensor.

The hoses I had were cold and didn't like to go on, I simply but them in hot water to warm them up, that helped a lot. Also I reused most of the clamps. I couldn't get the clamps onto the new hose that connects the thermostat housing to the reservoir (small hose) so I used cheapies I had laying around. One broke but fortunately is tight, I figure I won't ever have to replace the hose again so oh well.

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.

Took me about 3 hours, no I'm no mechanic...
