Coolant Leak From Heater Core: Lincoln MKZ Heating & Air Conditioning

Problem overview

A coolant leak may develop from the heater core. The failure may be due to electrolysis. Our technicians recommend to check for voltage in the coolant with the battery disconnected. If voltage is found the cooling system should be flushed and jumper wires added to engine ground straps as necessary.
