yes you can,drain coolant from the radiator,remove radiator hose,detach the thermostat cover from engine , remove the thermostat noting the direction in which it was installed in block. remove the gasket and thoroughly clean the sealing surface , refit the therostat.rifitting is the reverse of removal.

A cracked Intake manifold. Check the manifold in two places, on the front cross over behind the alternator and the base of the heater hose connector on the rear of the passenger side.

thermistate housing is the place you refer to it fuction is to hold a thermastate to open and close water flow at 150 to 190 degree according to car spectif the thermaste sticks it causes overheating and can blow the thermastate gasget, the tole cost is about 30$ at most for the thermastate and gasget...now many other things can cause a car to over heat and cause a hose leak and somtimes it is simple to just tighten the hiose clamp at the thrmastate and problem sovled see a water leak causes the radiator to lose presure and thus with out a sealed tight water cooling system the boiling point of water is lower and thus the car over heats when in doubt stop by the local gas station and have a tech take a quick look as it could be simple as the hose clamp difficult as a therm,astate but do not let it go to warp a head gasket as this blown headgasket is what is the end results of running a car to hot

It needs to sit in a recess in the housing, typically if you are asking the question that you are asking, the thermostat housing may be bent or cracked. If it is nto installed correctly, it kills the housing...Must be perfectly true, and sqaure....
I am not sure about the gasket, if it came with, use it, some designs use o ring to seat the thermostat, others use o ring as seal...
i normally seal it anyways...

If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.

Print Here is how to do it,if it does'nt fit right make sure you have the right thermostat.
CAUTION Never remove pressure cap with the system hot and under pressure because serious burns from coolant can occur.
