I am probably going to be swapping a crack-free dash in sometime soon. Since I will be in there, I suspect that my heater core is leaking somehow since I get a whiff of coolant when I turn the heater on sometimes, and there is a little coolant spillage on the firewall (engine side) where the hoses connect to the core pipes. Do I just need the 3 O-rings shown on RealOEM, or is there more I should replace in the heater core while I am in there?
Any other maintenance items that I should consider doing while I am in there?
