Default Run Grand Am GT 3.1 without thermostat, just for a bit?

Hello all,
I have a leaking water pump because of backed up pressure. It just blew out and sprayed coolant all over. I suspect I need to replace the thermostat, may not be opening correctly. Obviously the pump too.

My question is...

Can I to try to remove the thermostat then run the engine from a cold start without it to relieve the pressure? I just need to drive it home like that, one time, about 4 miles. Then I can fix it properly.

Thanks,
Shawn

It shouldn't hurt anything, I never ran thermostats in any of my racecars

It may throw a code because the engine is not warming up properly and idle higher while the engine is not up to temp.

For a short distance it shouldn't be a problem. Just make sure and run to the local parts store and pick up a new one, they're cheap.

you cant really remove the thermostat on these as the rubber ring is the seal as far as pressure it is supposed to be there you may be able to try just filling it will water and babying the car home but if you can figure out a way to seal the thermostat cover such as riping the guts out of the thermostat then yes it would be fine to run but could set a engine code good luck!(: also if you think you are having pressure problems try replacing the radiater cap as well should be a 15 or 16lb cap hope this helps.
