Thermostat

HI
Is it really mandatory to install a radiator thermostat. My 350 Chevy engine runs perfect with out one. It runs about 180 in winter and 190 summer.

Why don't people use the search function here, up at the top??? Search thermostat, over heating, etc., you'll find tons of information.

Here's a recent example, and there is a thread posted right before it was posted.

old school sbc's seem to love 180 degree thermostats

helps with warm up and can actually help prevent overheating because water stays in the radiator longer thus staying cooler

A thermostat provides a couple of functions. First, it allows the engine to warm up quickly and evenly. Second, it provides a slight restriction which forces coolant to actually slow down a slight amount, forcing it to fully distribute through the block, eliminating hot/cool spots. You can be rest assured that if a manufacturer could eliminate that vital component he would, saving a few bucks per vehicle for that profit line. Use a 180* and you should be fine.

slowing down the coolant CAUSES hot/cold spots.


The singular purpose of a thermostat is to ensure the engine is running HOT enough. If it is not then you will see increased wear and oil contamination.

Okay buddy.

I suggest you do a little reading about normalizing closed loop cooling systems, it's really not rocket science but maybe its the simplicity that is too hard for you to grasp.
