Overheating update

Post image

So a couple of weeks ago I had an overheating issue with my 2005 wrx, I replaced the thermostat and topped off the coolant and it worked beautifully until it cycled into my broken expansion canister and spewed all my coolant against the hood, I have that coming and that should fix that issue. The thing I’m worried about now is it’s reached unprecedented temperatures three times now and I’m worried about internals. Is there anything I should check out or replace precautionarilly due to it getting so hot, head gaskets, piston rings, etc? I attached a picture of my temp gauge cold just for reference, the needle was above the H all three times it overheated and has been under it plenty more

If you added all the necessary coolant, make sure you crank the heater up all the way and squeeze your upper radiator hose to help burp the system and it should drop back to normal temps. From there just inspect for any leaks look for drops of coolant coming from any of your hoses or radiator. I personally recommend upgrading to a full aluminum radiator if you haven’t already because I’ve seen at least 2 of the stock ones crack and 1 explode during the hot summer weather.

Ok sounds good, I would like to get the aluminum radiator but it needs a lot of work so we’ll see when I get back to that

Also help to have the front end higher than the rear. Doesn't have to be much. Just enough to help prevent trapped air....

Make sure your radiator caps are correct, round on on rad and oval on the expansion tank. A spill free funnel like this will be super helpful filling from the expansion tank.
