I did a search but didn't get the information I wanted.
I went out today and checked my oil and coolant. My oil was fine, so I took the radiator cap off, which kind of stuck for a moment, and noticed my coolant was a HAIR empty. But I also noticed that around the INNER EDGE of the Raidator Filler, what you put the radiaor cap on, had surface rust all around it. The coolant looks fine, but I don't want to have to deal with rusty coolant down the line.
So I think my radiator cap is leaking, since there is a little crusty remnants of antifreeze all over the outer circumference of the radiator filler.
So my question is is, what do you think I should do?
Should I take my car to the MOD friendly dealer and claim warranty, because I really don't want an entire rusty radiator system, which will happen if I don't act now.
Is there any way to kill the rust around the inner edge of the radiator filler?
I think my radiator cap is the culprit of the rust and the crusty remnants of antifreeze. So I am going to replace my radiator cap.
Should I go with a STI cap. Like this thread is talking about?
STi Radiator Cover
I would like some comments and or suggestions.
