Re: Roadmaster 5.7 Operating Temp

I have a '93 and the temp gauge runs in the same area. I changed the thermostat (195 degrees) and it still stays about the same. It went above it once to about 190 while driving in 90 degree weather through the mountains.
Oil pressure - normally shouldn't peg the gauge, but should drop after the oil heats up & thins out. Might be a bad oil pressure sending unit.
