You can find it in a service manual. under the plastic engine cover is a small valve to release the pressure. It is a two brass screws one into the other. Then you open the radiator drain on the lower driver side part of the radiator. If you want it all out of the engine block then you go under the engine on either side and also remove the "knock sensors." you have to disconnect the electrical plug from them first and more coolant will drain.
A 2001uses R134a refrigerant.
It doesn't have one.
Just beneath the lower radiator hose is the drain.
There is a low level sensor in the side of the radiator. They do go bad.
The only information I have found on this one is that it is located in the coolant pump.
The low coolant sensor is located in the side tank of the radiator.jd
It should be between #3 and #5 spark plugs.
the coolant level sensor is probably stuck it is on the bottom of coolant resivior most times all it takes is a tap with the handle end of the screwdriver on the side of the res where sensor is
I'm gonna take a shot in the dark on this one and say that it might need some coolant added.
The low coolant sensor is located in the side of the radiator. It can be unplugged but then how will you know it is low.
You should be able to reset the low coolant light by the parking light switch 3 times on and off somewhat quickly should do it
