This page shows the coolant sensor and how to replace it.
'95 Subbie and '97 should be similar.
Engine Coolant Temperature Sensor Circuit -replace the temp sender under the passenger side of the throttle body and reset the mil light.
On a 2012 Subaru Legacy 2.5i, the engine coolant temperature sensor is typically located near the thermostat housing, which is situated on the engine's front, near the intake manifold. It is usually attached to the cylinder head or engine block. To access it, you may need to remove some components, such as the air intake duct or other nearby parts, for better visibility and access.
Should be located in a removable housing at the engine end of the upper radiator hose Drain about 1 gallon of coolant from the radiator Remove this housing Note how thermostat is installed Clean both surfaces Replace thermostat and gasket Re-install housing Re-fill coolant slowly to prevent an air lock Start engine and look for leaks Run engine to normal operating temperature with heater on Re-check coolant level
Coolant always goes in the top of the radiator.

bad hose, radiator leak, leaking into engine.
According to the Subaru service procedures, there is no bleeding necessary for the Legacy. Filling procedure is as follows. 1) Fill engine coolant into radiator up to filler neck position. Coolant capacity (fill up to

it is in front of the engine block under the water pump kinda low on the engine
the traditional reason your spark plugs are wet (engine flooded) is your coolant temperature sensor. if it faults and says the engine is cold, the electronic control module (ecm) thinks the engine needs excess gas to start and it will flood the engine. next time it won't start, unplug all four fuel injectors. get back in and start the car (it will run for 10-20 seconds, then die). get back out and plug in the injectors. it should start right up. it this works, replace your coolant temperature sensor. your fuel economy will improve, too.
To replace the water pump on a 1993 Subaru Legacy, first, disconnect the negative battery terminal and drain the coolant. Remove the serpentine belt, then take off the timing belt cover and the timing belt if necessary. Unbolt the water pump and replace it with the new one, ensuring to clean the gasket surface and use a new gasket. Finally, reassemble in reverse order, refill the coolant, and reconnect the battery.
Its under the engine, on the drivers side. Two bollts, you cant miss it.
