If you're Corvette has either a manual water shut-off valve in the heater hose or a continuous smell of anti-freeze in your interior - it's most likely that your C3 Corvette has a leaky heater core. Engine coolant circulates through the heater hoses and into the interior compartment to provide the heat needed for winter time cruising comfort. Sludge in the coolant system will cause the heater core to become blocked or even worse, causing a leak which in turn covers your floorboard and carpets with your Corvette's cooling system.
