The heater core was leaking onto the passenger floor so I bypassed it. It never gets cold enough to worry about it here near the coast. But I am wondering if I will hurt anything by turning on the defroster. Will it do anything at all? I thought if it was fogged up the air blowing on it might...
I popped the cap on the radiator this morning to check the level and the level was fine but it looked like a rootbeer float in there (Lots of brownish bubbles). The car was warm already if that makes a difference.
Should I be concerned?
