Saturn L300 Heater Core

Your L300 is a prized possession.

Select Your VehicleAnyone who operates a Saturn knows that when it comes to repairing their automobile only the absolute best replacement parts will do. When your Saturn L300 left the factory, it was destined for a driver who prioritizes an American name in their automobile. While it may not be difficult to buy replacement parts for Saturn vehicles, these days only the highest quality are required to fix your automobile. Make no mistake, you bought your L300 because you knew that you wanted horsepower and great value both rolled up into one vehicle.

Don't go too long without fixing your Heater Core... here's why.

Believe it or not, your car or truck's heating system is closely tied to its engine cooling system. The engine of your Saturn L300 circulates liquid coolant throughout the block to absorb heat, and sends this liquid to the heater core (a small radiator) through a heater supply hose when you want to warm your vehicle's cabin. This heater core is almost always installed on the passenger side of the firewall, and you can find a couple of hoses leading to it. To make a long story short, your Saturn L300 heater core is a small radiator that creates a pocket of heat for your blower motor to funnel air past as it goes through to the interior.

You've tried the rest, now try the best.
