The car is over heating it is a 1997 Subaru Legacy GT Wagon AWD

The light is more then likely being triggered by the computer seeing two different readings from the two vehicle speed sensors(front and rear)

I'm not sure about what gasket to check, but I've always left my manual tranny's connected to the transaxles and removed the axles at the transaxle. This made simpler by popping the ball joints out, thus allowing the hub assembly to swing away. Hope this helps.

Hello. Replacing the clutch in a 4WD is a pretty big job. Dealerships charge it as a ten hour job. It could take from 8-12. Joe

Sounds like the Coolant is not full and has a air bubble. It is very important to have the system filled complete. That would be the first step.Good luck and have a great day.

heater core could be plugged,try removing both heater hoses to core and back flush

Have you checked the heater core or maybe a door not engaging also check your vaccum lines.

This problem is usually caused when the transfer solenoid/valve assembly goes bad, it's located in the transmission extension housing & needs to be replaced. it can be done without removing the transmission.

replace temp sensor for the emission system. there are two on the engine.

I have a 95 Legacy Wagon and by the shop manual the therostat sets on the bottom of the water pump. It is accessed from the bottom of engine by 2 bolts that hold the lower hose on.
