I have an Overheating issue
Started last week & I noticed my gauge climbing so I switched off the motor & let it cool off.
Later that night I topped up water & couldn't get the car to overheat again to diagnose it!!!
So run for a week & no problems, then yesterday it overheated & I started checking, the top radiator pipe was hot & the bottom was cold. Strange so I assumed thermostat.
Got a new thermostat fitted today genuine Subaru part, took it for a spin & started overheating!!
Did a pressure test & found one of the radiator hoses was leaking so I fixed that.
Finally built up enough courage to TK test & thankfully it's not head gasket failure.
So now all that's left is water pump or radiator blockage.
Water pump was replaced by previous owner so I'm thinking it should be ok.
I also tried to burp the system for air lock, but not sure I did it properly, I left the radiator cap off & left it to idle with heater on & fan off, topped up water for about 20minutes & then took it for a spin, overheated.
I'ts really strange how the bottom radiator pipe is still so cold. Clearly the thermostat ain't opening.
Now I'm wondering if there's any other suggestions, before I remove the radiator to get looked?
