05LegacyGTGa Posted November 16, 2017 Share Posted November 16, 2017 Finally took a quick video of what the coolant tank (or whatever the proper name of it is) sounds like on my car after every time I drive it. Is this normal or do I have an issue? Link to comment Share on other sites More sharing options...
relative4 Posted November 16, 2017 Share Posted November 16, 2017 Not normal. Are you experiencing any other symptoms - overheating, underheating, low coolant, engine performance problems, check engine light? If not, I would start by replacing both radiator caps. Note they are different part numbers. Link to comment Share on other sites More sharing options...
MilesA Posted November 16, 2017 Share Posted November 16, 2017 Can you hear any noise from there when the engine is running? Have you serviced the cooling system recently? Link to comment Share on other sites More sharing options...

Note they are different part numbers. No overheating or underheating that I've noticed. I'll add just a little bit of coolant to the overflow tank maybe every oil change. I was previously getting a CEL randomly for system too lean. One other thing, my heat does seem to come and go when I'm using it. But I also have that constant ticking/gurgling etc under the dash that these things seem to be known for. Link to comment Share on other sites More sharing options...

I haven't tried listening for it while running. I just always notice it after I turn it off. It's probably been over a year since I've had the cooling system opened up at all.

JmP6889928 Posted November 18, 2017 Share Posted November 18, 2017 Burp the system. It sounds like air in the system and your heat coming and going, sounds like an air bubble around the turbo. Jack up the RF wheel as high as you possibly can. When it's cold, remove the cap, start the engine and wait for the coolant to go down and add as needed.

05LegacyGTGa Posted November 18, 2017 Author Share Posted November 18, 2017 I take it you didn't like this one? Doh! I thought I said something to that. The last time the system was open, I put new ones on it from Subaru. Link to comment Share on other sites More sharing options...
