1992 subaru legacy 2.2 liter overheating and no heat. already replaced waterpump,thermastat, radiator and hoses


You mean the car is running fine but just No Heat?
If so
-Sound like the heater hoses are plug. or the control valve is no function

-Check the heater control valve and flush the heater unit with water of garden hose from both directions.
Q: How do I know that is working or not?
A: Slide the heater control from Hot to cold or cold to hot and check it turn or not. (If not turn at all. The cable is broken or slip off)

Water pouring in floorboard and engine over hating followed by steam coming out of the vents


It sound like your heater core is leaking coolant.

To get by for awhile you can bypass the heater core, but then you will have no heat or defrost

89 740 volvo GL heater failure


Several suggestions:
  • Your thermostat needs replacement and your dash gauge is not reading correctly. Cheap and easy to put in a new thermostat to confirm.
  • Your heater core has a deposit of sediment or minerals restricting the flow of warm coolant in which case the system may benefit from a backflush.
  • The heater water valve has a blockage restricting flow and may be in need of replacement;
  • You have a vacuum leak which causes the heat vent control to work improperly;
  • Your firewall-side heater water valve was installed backwards; The arrow on the valve points to towards the firewall inlet, not back towards the engine.
  • Control cables from the heater control unit to air mixing doors are maladjusted or broken. In heater-only cars (no AC unit), the water valve (which is inside the cabin, above the left footwell) is controlled by a cable from the air mixing door.
  • Check the heater hoses, I have seen several 700's where they are swapped over and it results in ZERO heat. See the section on Water Valve Replacement for correct installation instructions.

Temperature control knob turns but doesn't change temp.


the heater control valve is visible through the speaker cut-out; it's at the end of the plastic heater control rod, inside the car - not on the other side of the firewall! It's connected to the valve with a plastic "universal joint".

Check that the valve is actually being turned by the rod. The connection might not be good (pulled apart or broken), and or the valve might be stuck.

No heat


Your heater control valve isn't opening to allow the hot coolant from the radiator to flow thru the heater core. It's located in the engine compartment, at fire wall in the heater hose line. Let me know how u make out.

Smoke or steam coming from vents, not overheating, codes read 12 and 43.


I think it probably is the heater core leaking.As the water eats up to boiling point small cracks will allow steam to escape. Probably smells like coolant.
