When we get to Arizona. I'll decide if I should reinstall the 192 degree Motorcraft thermostat or not. I'll keep the truck setup to handle the worst circumstances driving, not the best.
what thermostat do you have in it now? you should l
keep the factory temp one In my opinion as opeating temp is a balancing game between fuel milage and wear on the engine (and other stuff)
I have a Mishimoto 185 degree thermostat in now. After we drive down to Arizona and see how the truck performs, I'll decide If I want to reinstall the slightly used new Motorcraft 192 degree stock thermostat. My experience is, this engine can get hot fast going up hills. I always have my INNOVA 5610 scanner connected showing live data, focus on coolant temperature. With the new radiator installed, You should think It will never overheat and blow out coolant again. Until I establish that it will not overheat, I'll keep the 185 in and the scanner connected. I see a lot of videos dealing with 6.0 Liter engines overheating. That is why they have a BPD kit to install a 7.3 fan clutch. I prefer what I did, installing the 6.0 Liter severe duty, snowplow fan clutch. I notice no difference in the amount of noise it produces over the standard fan clutch. It does get louder when I hit the blue switch to manually kick it on to lock up full speed. It rapidly drops the engine temperature when I turn that fan switch on. Highly recommend the blue wire switch mod to anyone. Another advantage getting the severe duty fan clutch instead of the 7.3 clutch is it works with the truck electronic control system, no engine light... That about sums it up. If the temps stay at 185 going over some of the big passes heading south on 395 and when we get down into Death Valley and Yuma. I'll decide if I want to reinstall the 192 thermostat. As I stated, I'll setup the truck for the worst conditions.
