Is deleting the thermostat a good idea?

[AnthonyA1234]

I have a heavily modified 2019 Tahoe. It’s got a built motor and a supercharger. Because of this, I’m running a colder thermostat, 160 vs stock 207. The problem though is that the 160 degree thermostats they sell have not been reliable for me at all. I’ve had three fail on me in a row now all around a couple months apart. When I pull them out I’ll see the wax inside the tsat has leaked out. I’m so done with dealing with this and I’m wondering what would happen if I just delete the thermostat and had it always flowing. Would this be a good idea?

If not this is there another option you guys can think of?

Deleting isn’t a good choice. Out of curiosity what are you using and if you’re not have you tried Stant tstats? On built motors and engines that are worked a larger radiator is a must, if you’re not doing that as well. All that said we use to always drill a 1/4” hole in the tstat to avoid a system failure like you’re dealing with. It’ll let the system still circulate but will still let the tstat function correctly. It will take slightly longer to get up to temp in colder temps setup like that but will be mostly unnoticeable in the warmer temps.

I would use a stock thermostat. It's better for the engine to run at the correct temperature. When it runs colder, you accelerate the wear rate. Sure, you can make more power with a cold engine, but I doubt it will be a noticeable difference unless you are trying to gain a couple hundredths at the 1/4 mile track or something.

I’ve seen people try this years ago, always resulted in overheating. The water doesn’t have enough time in radiator to cool sufficiently.

I ended up putting the oem hotter thermostat and the car is running perfectly at operating temp. What happened was my mechanic put a colder thermostat as a precaution when I did the supercharger just to ensure things don’t overheat. The problem is that these colder thermostats kept bursting. Put the oem thermostat back in and there’s no overheating issues and now I don’t have to worry about it bursting on me

If i was you, i would get a new mechanic
A tstat only regulate the minimum temperature, not the maximum
What control the maximum temperature is the cooling system Btu’s capacity

And a better quality tstat. 160’s are the norm for fi’d setups. That’s what whipple shipped with the kit I used as well.

Bam....you beat me to it. Absolutely. I have literally installed warmer thermostats to fix overheating problems. Any modern engine is designed to run at constant, warmer temps.
