Default thermostat question???

if running the motor cooler is better, what will happen if instead of installing a 160 t-stat, can you just the take the t-stat out of the housing and run the motor with out it??? what are the pro/cons about running it like this???? has anyone tried it??? I know my dad on his early vehicles, the first thing would do was pull the t-stat off of the and I believe they will run~100degrees,...

thank you guys>....

the thermostat controls the flow of the coolant (DUH). if the coolant has no restriction or control, it's heat transfer properties have just flown out the window. i have seen motors either overheat or never warm up. i would tend to lean towards overheating.

Down here in Houston, TX you can remove it. It doesn't get that cold down here. When it does......it sure isn't staying for long.
The only disadvantage you will have is that your engine may take too long to warm up or stay in the warm up stage for way too long and cause your computer to think the engine is still trying to warm up. When the PCM thinks this, it will give you a rich mixture causing poor gas miliage.
After 135-145* then the PCM will go out of the warm up program.
Just stick with the 160* stat. Will save you a lot of headaches.
I know you will definitely not overheat by removing the t-stat though.

thanks guys, I was just wondering because my dad used to do it, and he would actually put the thermostat back on during the winter for quicker heat, but that was on an older model truck 1992, which does not have a pcm??right?? but as far as gas mileage, truck always gave him the same gas mileage and he never had a problem with it and sold it with 195k miles on it...

Yes you can overheat by removing the tstat. I know of a couple people around my area, one guy with an 02 and one guy with a 99. They took their tstat out hoping to make it run nice and cool and both of their motors got real hot. The cooling systems on these newer engines are alot different than they used to be.

It can over heat because the there is no way to hold the coolant in the radiator for x amount of time to reduce the heat of it. The coolant just constantly recurculates making the radiator useless.

Even if it didnt overheat I wouldnt do it because engines are designed to operate in a certain range, once in that range oil is reaching all the parts and its viscosity is different. You would be more prone to engine sludge with the thing never heating up also it would cause excessive and exaderated engine wear running that cold. Thats why I went with the 180 stat instead of the 160

but to each his own.
