What is Heater Core Replacement?

A heater core is a small radiator that receives hot coolant from the top of your engine. You engine’s water pump circulates coolant from the main radiator into the engine and forces a portion of that hot coolant into the heater core. The hot coolant flows through the heater core and returns to the water pump through a second heater hose. With your blower fan operating, the heater core can add 85° to 100° above outside temperatures, giving you’re a maximum cabin temperature of up to 90°F.

How is Heater Core Replacement Done?

1. Disconnect the vehicle battery and remove the steering wheel.
2. Remove all outer doors and casings from the kick panels, fuse box, and speakers.
3. Remove any gauges, radio, speakers, glove box, and any other accessories.
4. Detach your air conditioner control panel.
5. Unbolt and carefully remove the car dashboard.
6. Identify and disconnect the 2 heater hoses.
7. Shift air ducts and other components away from the casing/housing of the heater.
8. Finally remove the heater core from its casing/housing.
9. Remove any fasteners or screws to gain free access to the heater core itself. Take the old heater core out and simply insert and fasten the replacement.

Recommendations

Antifreeze is also toxic and if somehow ingested, it can make a person very ill. Ethylene glycol, methanol and propylene glycol are among the main ingredients present and may lead to serious symptoms if not immediately treated.
