Need to replace thermostat, and new radiator cap. Have any instructions?
Assuming you have the Northstar engine.....
The thermostat in the northstar engine is located at the bottom radiator hose (unlike most conventional cooling systems), the hose connects into the housing where you will also find the water pump.
You will need to remove the air filter housing and air duct to gain easy access to the thermostat.
Remove the hose from the housing,then remove the two bolts on the flange,the thermostat can then be pulled out.
Take note of the orientation of the thermostat as you remove it.
The thermostat in the Northstar engine is a duel action device.
One end of the stem is the Thermostat(obviously) and at the other end is a spring loaded pressure valve(the thinner end).
Make sure the thermostat end is nearest the rubber hose and the pressure valve end is in towards the engine.
Don't forget the new gasket when you install your new stat, you may have to order this separately.
There is no radiator cap.The only cap is on the purge tank and these are quite cheap to buy and easy to replace.
