Want this question answered?
The water pump on a 1991 Subaru Legacy is in the engine compartment. It is found at the base of the engine.
replace heater core. replace fan.
it is in front of the engine block under the water pump kinda low on the engine
Yes. You cannot see the water pump because it is in position to be driven by the timing belt. Always replace then together.
Water pump is run by the timing belt. So, you have to do everything required to replace the timing belt plus a few more capscrews that hold the pump in. These should be done at the same time, 10 years or 100,000 miles, which ever comes first.
If you change the timing belt, I would replace water pump as well. Unless it's not working I would not replace it....
in with the timing belt change them at the same time
It means that the gasket seal on the water pump is bad and you need to replace it before you drive the vehicle.
You need to burp the radiator and cooling system.
See your user manual, its great for help with all the basic maintenance
For the heater core. All cars have them.
If I did it would be because there is a flaw in the gasket that seals the trunk lid. To find it take a flashlight and have an assistant with keys close you in the trunk. Have your assistant run water from a hose over the trunk lid while you look at the seal from inside. You will find your leak.
