More about Subaru HG problem


Asked by May 26, 2017 at 01:49 AM about the 2009 Subaru Forester 2.5 XT

Question type: Maintenance & Repair

After my diagnosis of bad head gasket in Subaru Forester, I've been putting in
coolant every couple of days. I got an oil change and I'm watching the oil and
it doesn't seem to be burning it or leaking or cloudy.
Nothing leaking on the ground. Just using or losing coolant. Could it just be a
leaking radiator or hose?
Is it possible it will go for a while like this? I need to buy myself some time.
Anyone know about the Subaru radiator stuff mentioned in an above post?
Can it be ordered? The mechanic I asked didn't know anything about it. Dealer
is too far away and has bad reputation. Thanks for your input.

Leaking headgasket will only get worse as time goes by, coolant in the oil or oil in the coolant, white smoke on intial start up, fouling of O2 sensors and possible catalytic converter damage, and even possibly hydro locking of the engine. Using a sealer might give some time but using those tends to lead to other trouble like plugged radiators, heater cores and on some engines, blocking smaller coolant passages resulting in an engine hot spot that can cause sever overheating ruining what would have been a savable engine. So things will only go downhill from here.

Head gaskets going bad in Suburus is a common problem. Get it fixed or it will only get worse. Putting a bandaide on it is not a solution to the problem. Also a bad head gasket will not always put coolant into the oil.

You could try using some Subaru brand anti-leak to temporarily stop the HG problem but you really should have it fixed correctly with new multi-layer head gaskets. Do the timing belt and water pump while you are at it.

You can buy the Subaru brand anti-leak at Amazon.
