hi, what would happen if i ran a car with out the thermostat? would is lower or raise the pressure inside the radiator?

 

that's probably not a good idea...
the engine will not get hot enough then.
i don't think it would affect the pressure since it's a closed system

True,it's the rad cap thataffects pressure.The thermostatinitially stays closed to help warm up the engine to operating temperature,and,then,it opens and closes to help regulate the engine at operating temperature.

 

Not a good idea

 

The engine won't reach operating temperature and will run rich forever.
If you have problems with the pressure in the cooling system there must be a leak somewhere.It is just as easy to replace the radiator as it is to remove the thermostat so I'd fix the leak.If the leak is internal it's only a matter of time before you get water in the oil and that's a sure path to a ruined engine.

 

You're engine would run colder, alot colder. You probably wouldn't get much heat from the heater either. Not fun if you drive in cold climates.

 

Emissions and mileage will be worse, prolly make less power and everything will wear out faster.

 

terrible idea!

 

Actually, the engine may warm up, it will just take longer. If the engine is having overheating issues, removing the thermostat will make it worse. The thermostat also regulates flow so that the coolant has time to absorb the heat from the block/heads.

 

wow guys thanks, yea i have way too much pressure in the radiator. and i just replaced it too and had it professionally installed. i think the gaskets goin out of head is cracked
