Car is overheating please help???

How easy of.a fix is this? And will I need to replace the head?

Typically the fix is to pull the engine and install new multi layer head gaskets. The heads should be checked for crack and warp by a machine shop. The unfortunate thing is your car may not be worth fixing. Get quotes from experienced Subaru mechanics and make your decision.

Not so typical in the late 90's, but these are so old that you may need to toss this beast. First check the heater tubes (behind motor) for a clog, as well radiator flow. Water pumps are golden, as are the t-stats, so proceed with a percolation test for exhaust gases and profuse bubbling upon warm throttle at the radiator cap. Be careful to not burn yourself! Good luck, as I fear you'll be tossing this dinosaur.
