I had the low coolant level light come on in my car about two weeks ago. I was close to home so I just drove it home.
When I got there, the surge tank was empty, so I filled it with a bottle of 50/50 I had in my trunk. Then I noticed there was a pretty decent leak coming from the heater inlet hose.
I tried to change the heater inlet hose, but it turned out that the plastic (!) pipe that was the inlet of the heater core was the part leaking, not the hose.
So, I replaced the heater core and now the system is full and there are no leaks......
BUT THE LOW COOLANT LIGHT IS STILL ON!!
What's going on?
Thanks!
