How can I tell if my Subaru is overheating?
You can get another fairly definitive test response by having a hydrocarbon sensor “sniff” the bubbles emanating from the coolant (rad cap or expansion tank if visible) to show exhaust gases present in the coolant. That nails the diagnosis.
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.
Can a bad head gasket cause a car to overheat?
If it is loosing coolant and it is not a leak, it is most likely a head gasket issue. When having a bad head gasket coolant sometimes goes from the head gasket leak directly to the combustion chamber and the problem will not put oil in the coolant and vice versa.
What should I do if my Subaru water pump overheats?
Also note that Subaru water pumps are also ultra-reliable, so when you replace the HGs DO of course replace the t-belt (since it comes off!), and test its tensioners, but leave the water pump alone to save a few bucks. Sounds like heresy, but remember that Subies are unlike Hondas, Toyotas and VWs that eat water pumps for lunch.

What to do if your Subaru heater overheats?
So before you bite the $1500-1800 bullet, at least spray-clean the front radiator surface of debris, and disconnect and with a garden hose BACK-FLUSH the two heater core hoses under the windshield.
What causes a Subaru head gasket to overheat?

Why does my Subaru Outlander have a bad coolant leak?

What to do if your Subaru engine overheats?
Once coolant leaks into your car’s cylinders or into the combustion chamber itself, you will see telltale white exhaust smoke. If the radiator in a Subaru is repaired or replaced, it’s best to test the vehicle before taking onto the road to ensure that the engine won’t overheat again.
Why does my Subaru engine keep running out of coolant?
In this situation, the coolant repeatedly needs replenishing, despite there being no trace of oil or fluid on the ground. The likely reason is that coolant is being sucked into the head gasket and ejected from the exhaust.
Can a Subaru test be inaccurate if the engine is cold?
A Subaru test can be inaccurate because it’s performed while the engine is either cool or only lukewarm. For instance, if the engine is cold and the pressure is only 15 to 20 psi, the breach could be hard to detect because the gasket seal will likely perform as expected.
What should I do if my Subaru engine is leaking?
The problem drew protests that prompted Subaru to extend its warranty plan and add an anti–leak cooling system conditioner. In order to stop leaks before they get out of hand, the engine’s bottom should be inspected by a technician during each oil change.

Can a Subaru T-stat thermostat be bad?
Note also that unless you’ve replaced the OE big thermostat with a cheaper, smaller-orificed aftermarket one, the OE t-stat is NEVER the culprit in this scenario, so don’t bother to replace it if it’s the big OE one. I’ve tested so many of these and NEVER found a bad one, so don’t waste your time.

What kind of car is 2006 Subaru Legacy Outback?

What causes a Subaru 2.5L engine to leak coolant?
Faulty chemistry and corrosion are a common problem on older 2.5L models, in which coolant tends to leak from the left–side cylinder. This problem has largely decreased since Subaru added ground straps, which protect the most vulnerable part of the head gasket.
If it is loosing coolant and it is not a leak, it is most likely a head gasket issue. When having a bad head gasket coolant sometimes goes from the head gasket leak directly to the combustion chamber and the problem will not put oil in the coolant and vice versa.
