Water pump or head gasket
I’ve had what seems to be a head gasket failing symptoms the past week, pushing the coolant into the overflow and spewing it. Replaced the thermostat already but still no help. This is the best picture I could get to see the seeping, the picture is drivers side. Is it the head gasket seeping or the water pump?
Car is an 08 base impreza Thanks https://cimg1.ibsrv.net/gimg/www.sco...b177a254b.jpeg |
That looks mor elike a water leak, but if you're actually pushing water from the header tank into the overflow that's not a good sign.
Is the thermostat working and opening when required? Are the rad hoses hot etc? |
Whatever that is its been going on a long time. As BPR has said blowing water out of the reservoir is not good but I suspect a long term leak looking at that. If it we're me I'd would also be considering a new sump. Possibly a long term water leak which has resulted in an overheated engine and may possibly been the root of the problem cause as we all know the temperature gauges are useless.

Yes I've been constantly filling my overflow so much that it spews out. Some days are good and the coolant doesnt reach the top, others its all the way up. Is the thermostat working and opening when required? Are the rad hoses hot etc?

Oil doesn't rot sumps :) but coolant looks like that when dry as such.

It wouldn’t need a coolant leak to look that bad I’m afraid, I work on a lot and they are rotten, front arms and subframes, from low-ish cars as well, not million milers, Subaru didn’t build them to last long.
