Why does my Subaru Legacy overheat so much?
I have 2 Subaru Legacy’s. Both have given me the same overheating problem at various times. This mimics all the symptoms of a head gasket leak. But the solution is ridiculously simple. Air gets trapped in the heater element, which sits under the dashboard and is higher than the radiator so that the air does not bleed out.
What to do if your Subaru Outback overheats?
Get or make a u-bend of 16mm metal pipe and disconnect the two heater hoses at the firewall behind the engine and join them together with the u-bend and two hose clamps. The overheating problem will go away for good. But of course, now you have no heater.
Why does my Subaru radiator keep overheating?
There may be a problem (warp, a crack which opens in the neck) where the radiator cap seal sits against the opening of the radiator. Also, when a radiator is pressure tested, it’s usually only luke warm, by then. IF there is any crack which opens, it could be opening only when the parts are hot.
What’s the problem with my Sons Subaru Outback?
Well, I’m back…my sons Subaru Outback came back from the mechanic and was running without overheating for about a day before it started in again. They claimed it was the radiator cap. Then the next day it overheated again – they claimed it was a defective cap…now it’s back in there again, with the same overheating problem.
