Buick Rainier Heater Core

Why you drive your Rainier.

While it may not be difficult to locate replacement parts for Buick vehicles, these days the necessity for nothing but the absolute best are required to fix your car or truck. Buick automobile enthusiasts have become used to a certain level of reliability when driving their Rainier around town. Make no mistake, you didn't buy your Rainier unless you knew that you wanted efficiency and American style both rolled up into one car, truck, or SUV. Auto enthusiasts know that good looks is built into each Buick, and understand that only top quality repair Rainier parts will suffice when repairs are needed.

Why Heater Core replacement is so important.

Believe it or not, your car or truck's heating system is closely tied to its engine cooling system. The engine of your Buick Rainier 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 Buick Rainier 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.
