Question Runnig Open Thermostat?

So I tried doing a search for my answer but couldn't really find anything. I know that heat is one of the biggest killer of these engines. I live in Vegas where it can get up to 120 in the summer. My question is would it be good to run without a thermostat durrning this time? Is there any downside to this when it's that hot out? Wouldn't it keep everything cooler and running smoother? Let me know what you guys think.......

It would keep the motor cooler, but you don't necessarily want the motor running cool. It would be less efficient at say 150*, than 192*. A lot of the 6.0 guys will replace a thermostat when they're running just a few degrees low.


If you're having overheating problems, you might have other problems. If it's not overheating, don't fix what isn't broke.

I've only had the truck for a few months now. It hasen't been through a summer here. My ECT right not stays 180-190, depending on if I get on it or just putting along, and my EOT stay at about 190. My temps look good when I'm driving but I wanted to keep it that way. Thats why I asked.....

running without a thermostat will not make the engine run cooler, it will show cooler on the gauge but everything is hotter. There has to be a restriction in the sytem for it to properly absorb and dissapate the heat through the cooling system. Race cars don't run a thermostat, instead they use a restrictor in the housing to slow down the coolant flow to get the coolant to the temperature they want without running the risk of a stuck thermostat.

Agreed

if coolant doesn't stay in the radiator long enough it won't cool down

removing a t-stat in any application I have ever dealt with is a bad plan

Leave the thermostat in. You should not have a problem with overheating.

The diesel, being a compression ignition engine likes heat. It should have an egt between 190 and 200. If it is consistently running below 186 it would suggest the thermostat is stuck open and it should be replaced.

Typical eot should be 192-194 and eot 196-198. The 6.0 is not a gasser and gasser logic does not apply here.
