Heating/Heater Cores

In Boulder, we get some chilly, snowy winter weather, and therefore it is important to have a working heater in your car. Unfortunately, car heating systems are susceptible to failing and when that happens, you need a mechanic’s attention. During the cold months, it is imperative to have an operable heater and defroster. At Haglin Automotive, our expert technicians can determine the cause of the problem and fix it quickly and cost-effectively to get you traveling in comfort once again.

Your car’s climate control/heating system is driven by a heater core that works in conjunction with the engine’s cooling system. The system cools the engine by sending the heated antifreeze to the radiator, which allows outside air to blow across the radiator and cool the antifreeze. The antifreeze is then sent back to the engine. Hot antifreeze circulates throughout the cooling system via the radiator and heater hoses. When the car’s climate control heater is turned on, a diverter door opens to the heater core in the dashboard, and the A/C fan or blower directs air through the heater core, through the ducts, and into the interior of your car.

However, corrosion can build up in the system due to lack of cooling system flushes. In addition to serving as a temperature control substance, antifreeze also is a lubricant and rust inhibitor. If not flushed and replaced periodically, corrosion can develop. If antifreeze is dirty, it is a usually a sign of a coolant leak in the cooling system that has allowed air to enter the system. It could also be a leaky radiator/hose, water pump, or heater core. But no matter the problem, it must be remedied quickly to not only keep your car’s cabin comfortable, but also to prevent other underlying issues from turning into bigger problems.
