I have a 1998 Buick Century and while I was driving it the low coolant light came on. So I stopped at an auto place and had it topped off with 50/50 Dex Cool. When I went to start my car the heat my an awful noise and stopped working. My coolant light is also coming on and off, on and off. What could be the problem ? I don't believe there are any leaks. The heat is now barley on and I just want to know how to get rid of the coolant light. Thank you I'm advance !!!

Hello,
While the vehicle may have come with dexcool, most times it is changed to regular antifreeze because of compatibility and corrosion issues.
If, at some point, your vehicle was changed from dexcool to a typical green antifreeze, adding dexcool could be causing your issues.
I recommend having it inspected before allowing the issue to continue.
As for the noise from the heater, I am skeptical, but that should be inspected at the same time.
IF carpeting is wet - it may very well be directly related to the noisy heater AND coolant loss. Good luck with it!
