If your car is overheating, and you don’t have money for a mechanic, you can try flushing the heater core redneck style. It’s not the best way to do it, but it might work in a pinch. Here’s how:
First, find a garden hose that will fit onto the intake and output hoses of the heater core. If you can’t find one that fits snugly, you can use duct tape to secure it. Once the hose is in place, turn on the water and let it run through the system for a few minutes.
HOW TO FLUSH A HEATER CORE REDNECK STYLE !!!
- Remove the radiator cap and coolant overflow tank cap
- Place a garden hose into the radiator neck and turn on the water full blast
- Once the water is coming out of the overflow tank neck, turn off the water to the hose
- Replace both caps and start the engine
- Let it run until it reaches operating temperature, then turn off the engine
What is a Heater Core
A heater core is a small radiator-like device that is used to heat up the cabin of a vehicle. The way it works is by circulating hot engine coolant through its thin metal fins. This heats up the air that passes through the heater core and into the cabin.
Heater cores are usually located under the dashboard on the passenger side of the vehicle. In order to access it, you would need to remove the dash panel. Once you have access to the heater core, you can then flush it out with a garden hose or pressure washer.
If your vehicle’s heater core is leaking, you will notice coolant on the floor of your car or a sweet smell coming from the vents. If this happens, it is best to take your car to a mechanic so they can properly fix the leak.
What are the Symptoms of a Clogged Heater Core
A clogged heater core will cause your car’s engine to overheat. The symptoms of a clogged heater core are:
1. Your car’s engine overheats quickly.
2. You have to keep adding coolant to the radiator. 3. The temperature gauge on your dashboard reads higher than normal. 4. There is steam coming from under the hood of your car.
How Do You Flush a Heater Core Redneck Style
If your heater core is leaking, you’ll need to flush it out to get rid of the antifreeze. Here’s how to do it redneck style:
1. Remove the radiator cap and pour in a gallon of distilled water.
2. Start the engine and let it run until the thermostat opens. This will circulate the water through the system and help flush out any antifreeze that’s left in the heater core. 3. Once the thermostat opens, turn off the engine and let it cool down.
4. Drain the radiator and then remove the heater hoses from the engine (be careful not to spill any antifreeze). 5. Flush out the heater core with distilled water until all of the antifreeze is gone. You can use a small funnel or a turkey baster to help with this step.
If your heater core starts leaking, you can try to flush it out yourself using this redneck method. First, find a hose that will fit over the radiator petcock and attach it. Turn the petcock until water starts coming out, then put the other end of the hose into a bucket.
Let the water run for a few minutes, then turn off the petcock and remove the hose. Next, open up the hood and locate the heater hoses. There should be two hoses going into the firewall – one larger than the other.
The larger hose is the inlet hose and the smaller one is the outlet hose.
