Engine & Oil Temps

[zzmac]

I just replaced my water pump gaskets and installed a new 180* thermostat. I drill a hole in the thermostat flange.

I drove the car this morning and the engine temperature stayed at 80*C / 176*F (highway) and hit 90*C / 194*F once on the street. The oil stayed around 80*.

Are these good normal temperatures?

You're not even in the HOT range...

It was a little chilly out this morning, if that matters. What temp should I be running at?

Temperatures should be evaluated after driving for at least 1/2 hour to fully warm up the oil. Typical water temps for a 180 thermostat are between 180F (highway) and 200F (in traffic on a warm day) could run over 200F depending on your cooling system capacity and anti-freeze mix. Oil temps should be at least 180F, to cook off water vapors, and can run to 250F or higher depending on whether you have an oil cooler and/or run the engine harder (more time at high rpms). If you are running an oil cooler on the street, your oil may not get hot enough. If so, you can block off the cooler, or install a thermostatic valve, or remove the cooler. Your temps look on the cool side, but re-evaluate after a long hard run. Hope this helps.

The simple answer is yes. I have had mine for 7 years at that temp, no problems.

Like mpanten said, leave it alone - you are good to go! Don't worry everything is fine.
