So I thought my system was sealed it just has an overflow tank so when it needs coolant It takes it out of the tank and that hose is above the bottom of the radiator cap.
It has a hot and a cold level on the overflow tank.
Yeah only the diesels got the sealed system in our trucks. The pressure cap is actually on the surge tank. There isn't one on the radiator. My Saturn is similar in that regard, although it has coolant hoses running everywhere.... more complicated system, I guess.
i’m replacing the radiator again now because the oil cooler is contaminated and I’m putting a new engine in didn’t wanna take a chance with trying to flush the oil cooler side out.
How is the oil cooler contaminated.... something in the oil from the old engine? The plastic on mine actually started cracking around the upper oil cooler port. That's why I replaced my last radiator. My original radiator broke in a similar manner, too, and then years later the oil cooler itself started leaking into the coolant. I think the upper hose tends to bounce around a bit weakening the area, so I zip-tied it down as best I could, this time.
