Re: Re: Thermostat or Water Restrictor/Washer...4.3L/5.3LI'm with you. And ditto the bypass.The factory ecm wants the engine to operate at optimum efficiency for combustion....That's why they regulate around 205-210. And also why I built my cooling system to mimic the factory with 190 tstat, steam lines, heater(or bypass), and sealed radiator with the cap in an expansion tank (tied in through heater loop and steam lines) with a separate overflow. Stays 210 all day long.For added insurance, I run a 50/50 mix, but I use a 20 psi cap (all -AN fittings in my system) to help raise the boiling point a bit for the long hard obstacles.Sent from my SM-G925R4 using Tapatalk
