The heater core actually works as a heat exchanger in your 1992 Volkswagen Jetta. It is like a mini radiator that allows the heat to be removed from the engine’s coolant, then transferring it to the passenger’s compartment. The heated coolant is transferred from the engine with the use of the heater valve and through the heater core, whereas the cooled coolant that will leave the heater core is then transferred back to the water pump to circulate again in the cooling system. The heater core is located inside the HVAC in order to control the flow of air from the passenger’s compartment. The air that is used for heating, cooling, defrosting, and ventilation is being directed by the movable doors in the plenum chamber. There are actually several types of heater cores available in the market, but the aluminum type is the most common produced by OE manufacturers. Aluminum is much lighter and could last longer compared to brass type heater core. If you often experience failure in your heater core more often than usual, perhaps you should consider replacing it. Our Febi aluminum heater core may be the perfect solution for your need. The Febi aluminum heater core is much resistant to corrosion, fatigue, and internal corrosion. These factors are actually the most common cause of heater core failure. The electrolysis condition is also a common failure in the heater core.

So make sure that the heater core that is used in your 1992 Volkswagen Jetta is in perfect shape. For the best deal in R3000-184823 Febi heater core aluminum, check out our online catalog now.
