Step #1. Locate the heater core

To start, you must locate the heater core in your car. If this is your first time opening or finding the heater core, it might take a while, but it’s okay. It is mainly attached to the firewall and away from your car’s engine. The heater core has two hoses, the inlet, and the outlet, passing the cold and hot coolant. The heat from the inlet hose travels to the heater core and produces heat for the car’s cabin. If you have trouble finding the heater core to the firewall, locate the coolant tank and follow the pipes, as these hoses lead to the heater core. 


Step #2. Cut the hoses

After locating the heater core and its hoses, you have to cut the hoses but before that, put an empty container below the car to avoid the excess coolant from flowing or splattering to the surface. Remember that you must be careful not to break or tear them down in cutting hoses, as you will need to repair them, and it can be time-consuming for you.  

Cut the inlet hose first by using a hose cutter. Allow the remaining coolant stuck in the hose to flow into the container. Y prefer you can attach another hose to the inlet to lead the coolant to the container. After successfully cutting the inlet hose, do the same method to the outlet hose.

Step #3. Flushing and backflushing 

After cutting the hoses, you can now proceed with flushing them out. In this step, you can use a 5-gallon container to see the amount of the grimes that built up into the hoses or heater core. Use a garden hose, attach the hose’s end to the inlet heater core hose, and allow water to flow for a few minutes. During the first few minutes, grime flows out from the outlet heater hoses.

You have to backflush it after flushing the water from the inlet and the outlet hoses. Insert the water hoses supply from the outlet hose, and the water goes out to the inlet hose. Remove the hose from the inlet hose and attach it to the outlet hose. Allow the water to flow again for a few minutes. In backflushing, you can decide whether to contain the water or let it flow to the water drainage.


Step #4. Air compressor 

After flushing the heater core, use an air compressor to clear all the possible grimes or dirt blocked into the hoses. In using an air compressor, you only need a little air, as high pressure can cause severe damage to the heater, so most people only prefer water flushing and do not apply air compressors. If you are unsure about using the compressor, skip it out or ask a licensed mechanic. Attach the hoses back together, along with the hose clamps. If you find your hoses leaking, make sure to replace or bypass them in the meantime.
