new engine is running hot

[4thgenowner]

Well I got my car back with the new engine and it is running very hot IMO. It stays right in the middle of the gauge and sometimes a line or two above close to the red. My old engine was always 2 lines above 100. I flushed everything and it still runs hot. Any ideas?

Before I put the 160* thermo in, my car always ran right at 210* (the middle line of the temp gauge). Now I run at 185-190*(again, based on the gauge). I never had any problems when running at the 210*, but I wanted to try the lower temp thermo. There seems to be a lot of variation between cars. I don't know if its the engines themselves running differently, or maybe more likely that there is a large variation in the gauge calibration.

I had the same problem with my 95 never was able to find the problem with it.

You may have an air bubble in the coolant system. It may work itself out or you may need to "work" it out.
