When your coolant circulates thru your heater core and radiator it creates a tiny bit of electricity that will slowly eat your heater core and radiator up from the inside out. The process is known as "electrolysis" and you can limit the damaging effect by grounding your heater core and radiator with a simple ground wire that is attached to the frame. Here's a picture of my radiator ground wire that is soldered to the coolant recovery tank outlet and grounded to the hood hinge bolt. If soldering or bolting isn't an option you can also use common alligator clips to connect to your heater core and radiator (I'm using a big alligator clip to attach to my heater core inlet tube).
