Engine Temp LA 360

195 and 210 are perfectly normal and acceptable.

The thermostat ONLY sets the low temperature of the engine.

The radiator, water pump, pulley ratio, fan blades and pitch, outside air temp, driving speed, engine displacement, modifications, etc are what set the normal operating temp.


As stated before as long as the temp stabilizes at 210 or there abouts you are fine.

IMHO as for 160 deg thermostat... It is not going to cool your engine any better than a 190. If you had an excessive amount of cooling capability. Your engine would run at 160. With a 190 it would run at 190.


The engineers designed the tolerances on the engine for a specific temp range. Too cold clearances are too tight.
