I'm sure I'll get crap for asking this but does anyone know what the OEM thermostat temperature is? I tried looking it up but got several different results. My engine just blew it's second thermostat housing. I ordered a metal housing but I also want to drop the engine's temperature. I'm down south where it's usually hot and my engine bay gets excessively hot and I'd like to lower the temperature just to be safe. has anyone ran a lower temp thermostat on these engines? Is there anything I need to know? On my Chevy S10 I run a thermostat that is 10 degrees lower than oem and that's fine for me. On a separate note who's hair brain idea was it to put a plastic housing unit where the heat of the engine passes through.
