Have a pressure test done on the cooling system to find the leak first then have a compression test done to check for head gasket or cracked head.

How to replace valves on a subaru legacy 2.2 1999?


this will require both head removal so if you are not competent to do the job have an accredited shop do it for you. There are timing belt/chain issues, head tensions, gaskets etc and if done by a qualified shop there will be a warranty issued with the job.

I got a 99 Subaru Legacy 2.2L Sedan. Recently hit and deer and blew head gaskets, overheated motor and had to replace. Everything starts smooth but when the car heats up, it acts like it's not getting gas....


I think you need to check your fuel pressure. If it's not between 41 & 45psi, you need to replace the fuel regulator. OBD doesn't always give the exact response to enable acurate diagnosis. Try this anyway, get back if still a problem.

1990 subaru legacy 2.2ltr auto with 189 kms. car heats up and pushes water out from reserve tank.no heat inside.new thermostat and water pump.no water visible in the engine oil and runs smooth.engine...


could be a crack in the cylinder wall on the low side, causing the compression to push the water out and not mix with the oil as its not leaking between oilway and waterway.

head gaskets are a weakpoint on the 2.2 and 2.5 as they are bored out to reach this capacity and this leaves less area for the gasket to bite down on around the cylinders. Fit a WRK steel gasket and get the heads torqued down properly, its a nasty job from an access point of view tho

1993 Subaru Legacy Sedan 2.2 liter engine, has and over heating problem. Replaced thermostat, replaced water pump, and replaced radiator with all new. Still over heating! Any ideas??


Usually the main reason for a Subaru to over heat is a blown head gasket. If it is pushing fluid out through the overflow bottle. I would suspect a blown head gasket.
