If you think the only consequence of driving with a bad Saturn heater core is that you'll be a little cold, think again. When a Saturn heater core starts to leak, it's only a matter of time before you end up with serious damage in your car's bodywork. Why? Because the Saturn heater core uses engine coolant to warm the air entering the cockpit. Engine coolant is mostly water, and when that water leaks out of the Saturn heater core and heads for the floorpans, rust is the result. Keep your car warm and keep it out of the body shop by installing a new premium Saturn heater core from us at the first sign of trouble. And what are the signs of trouble with your Saturn heater core, anyway? Low coolant level in the radiator is often the first sign that coolant is escaping, possibly from the Saturn heater core. If the antifreeze is low and you find unexplained dampness on the vehicle's carpets, you've most likely got a Saturn heater core leak.
