1992 ej22 overheating not circulating water through rad properly have flushed still probs

welcome subaru 92 how old are the thermostat, water pump and radiator? and have you checked the system for leaks?

you may have an air lock in the system you need to have the front of the car on about a 25-30 degree angle (parked on a hill radiator uphill:) ) from cold run the engine to operating temp this should get the air lock/ air out of the system

thank u 4 ur info i replaced thermostat yesterday,flushed radiator,used seal up,given her oil change,still has air lock:(. love da quote lol:)

Turn the heater to hot, the heater box is usually
where it is

It can take upto half hour till to get airlock out of the system!! Happened to me once that it was overheating and finally got it out in half hour later.

Have a feel on the radiator (be careful of fans - best disconnect it) if all of it is hot all over or half/half is an indication that its blocked.

Liberty has a constant flow heater, no valves to open, try quickly squeezing/pumping the top radiator hose with the cap on, check, re-fill, repeat until you don't feel air in the system, this works on turbo cars but not too sure about n/a's.
But you've probably got a blown head gasket, seems to be the most common cause and you don't usually get oil in the water or vice versa

Did you check the new thermosat in some boiling water? I find 1 out of 5 fail :s

I'd definately have the front of the car as high as possible to make sure there is no airlock in the system. I also use a funnel and keep it half full of coolant (make sure it's a good size funnel to allow for expansion) and try cover the front of the radiator (in between the A/C condensor and Rad) with a piece of cardboard but remove once fans come on.
