thermosthat?

Yep. Car needs to remain at a pretty consistent temp, the "operating temp" in fact, to operate properly. If you remove the t-stat you'll probably keep the engine too cool since the coolant will be flowing all the time.

I'm sure there's more to it than just that but the pros will chime in soon...

Either way, not a good idea.
 
Little confusion. OL is when the car is warming up. CL is when the car is at operating temps. Coolant does not try to cool down (generally) in OL.

No stat or restrictor plate of any sort will make the car take forever to warm up, and once it starts to get too hot, it will really get hot. NOT good.
 
Actually the computer is designed to work at certain temp thresholds. How that is achieved is of no avail.

(QDR, I know what you meant and am playing with semantics).
 
Bad idea - leave a t'stat in. And replacing it with a lower temp t'stat will not solve an overheating problem. By the way, the t'stat not only controls temp, it's also there as a flow control to limit velocity/flow in the system.
