Question about 1992 Subaru Legacy

My 1996 BG5 Subaru Legacy is over heating. I

My 1996 BG5 Subaru Legacy is over heating. When I checked the top radiator hose it was hot but the bottom one was cool. I assumed no ciculation. I tested the thermostat and it's opening in hot water. Pulled the pump out and it turns smooth with no noise or looseness. No leaks anywhere either. The timing belt is overdue so maybe it's slipping on the pumput I'm just cluching at straws. Driving me up the wall. I'm hoping you Subi experts out there have some ideas please.

Subarus are notorious for the system having air in the lines and if your thermostat is on the bottom of the engine a weird on thats on all the 2.2 i have owned if you have opened your cap and the system was just filled or antifreeze changed unplug your electric fans i would say put a new thermostat in first they are under 10 bucks better save than sorry with the fans disconnected it will get hot quicker it will also open the cold water at the bottom to open the thermostat your pump will circulate the water keep adding till full throttle up engine it will **** it down add some more let off throttle the coolant will start to flow out cap it off shut it down reconnect the fans but the cold coolant in the botton stays cold till the top water opens it up the thermostat the entire system needs to get hot mix and circulate get most of the air out.

yes worst case you may have head problems lost coolant leak waterpump or line leaking head problem if your fluids are low it will overheat if all the coolant is there and you replaced your thermostat there is a fix to drive a while longer and thats just removing your thermostat it runs cold and if its winter take forever for your heater to warm up sometimes not enough hot water goes through the weep hole in the thermostat too the little pin gets stuck if you smell antifreeze in your exhaust then yes a head gasket they will sometimes still run strong and be leaking and burning it off in the exhaust... i had one like that actually the heads were bad i just swapped another engine i had sitting around

You probably need to change both the water pump and the thermostat. Otherwise check you're spark pulgs. If you've blown a head gasket, your vehicle will overheat. Pull the spark plugs and if you have one plug that's nice and shiny, it could be that you're leaking water into that cylinder and you've steam cleaned it. I would then do a compression test.

You either have a stuck closed thermostat or the engine has a leaking head gasket.

The heater just quit working. It worked fine yesterday but this morning it does not. The car is running a little hotter trhan normal but not overheating. Any ideas?


I would check to make sure the radiator is full and the overflow tank is filled to the proper level. It doesn't have to be very low for these cars to stop blowing heat.

We have replaced the radiator, flushed everything, replaced the thermostat, and checked the new one in boiling water and it works. Bottom hose still remains cold and top hose is hot. When we test drive...


Have a shop do a "block check" where they put a canister above the radiator filler and check for Combustion Gases" the chemical is BLUE.... if it turns YELLOW , thats a sign of CO2 in the cooling system and most likely will need head gaskets, or worse.

Water is not circulating car gets hot and expansion tank fills then suddenly after some time it will **** the expansion tank dry and drive at normal temp again 1995 subaru legacy 250t


Sounds like your thermostat has gone bad and needs to be replaced.
Your thermostat is located under a metal housing on the top of the engine. The upper radiator hose connects to this housing. To change the thermostat you basically need to drain the radiator after your engine is cold, disconnect the upper radiator hose from the engine, and remove the bolts from the small housing. replace the thermostat, and clean the surfaces on both sides and replace the gasket too. reinstall the housing, attach the hose, and refill the radiator. start the engine, warm it up and check for leaks, then re check the coolant level after the engine cools off again

1995 Subaru Legacy Wagon Radiator


Hi sir, if you want to do a proper job here's how.
  1. Get radiator flush let you car Idle for a while or drive for 15 min.
  2. Let Car cool Down
  3. If no drain PLug remove the hose at the bottom this is the same pipe going into your water pump, Work gentle with it try not to damage the pipe.
  4. open your rediator cap, this will allow the water to train from radiator.
What about all the dirty water inside the engine? this is how to do a decent flush.

  • The car should be cold
  • remove the water pipe at the top of the radiator
  • take your garden hose and insert it to the rediator don't force it just hold it there.
  • Start the car let it idle, open the hose pipe.
What happens now is that the water pump pulls all the clean water trough the rediator and pushes all the dirty water out the other side.
  • when water is clear turn off water
  • kill engine
  • Tighten water hose
  • refill with good Anti freeze anti boil and top op with water
  • drive the car till hot
  • check for any leaks on the pipes you removed before
Hope this Helps

the bung is on the bottom right (left as you look at the car) and is black in colour with what looks like a wind up toy key shape on top. its damn hard to turn though so give some pliers ready. or just take bottom hose off. it doesnt matter how you get the water/coolant out really.
