What does a heater core do? A radiator-like component that is all about keeping the right temperature in your vehicle, the heater core functions as a modulator of the automotive heating and defrosting process. It is in charge of the circulation of warm air inside the cabin, ensuring, for one, that your windows don’t fog up. The heater core makes this possible by ensuring coolant flows properly through the hoses.
So where is the heater core located? It’s usually found just behind your vehicle’s dashboard. The center part of the passenger side is where it should be (it is uncommon to find the heater core in other locations). To easily identify the heater core, search for a small radiator that has a small conductive tubing and piping. If you’re having trouble locating the heater core, consult your car manual.
A malfunctioning heater core could be hard to deal with when you’re on the road, especially if you have passengers. Look out for the following bad heater core symptoms:
- Fogging out – Is every window of your car always covered in moisture? If the fog accumulating inside your car looks nothing like simple mist, that is a sign that your heater core might already be broken.
- Sweet scent – Is there a fruity smell—almost melon-like scent–wafting in your vehicle? Better check the inside (or even the outside) of your car and keep an eye out for leaking radiator fluid.
- Thirst for coolant – Does your car not have enough coolant? Leaking coolant can be due to a blown heater core. Make sure to examine your passenger-side floor and look out for puddles.
- Uneven temperature – Does it get chilly on your car’s passenger side? If so, this could be the perfect time to check your heater core for holes.
You can follow the steps below to temporarily bypass the heater core:
Step 1 – Remove the dashboard cover. – Take off your dashboard cover to access the location of your heater core. You might need to disassemble your entire dashboard or just take out your air conditioning gratings. The complexity of this step depends on the exact location of your heater core.
Step 2 – Detach the hoses. – Before working on your heater core, make sure it isn’t hot. The same goes for your engine. Take some time to let your vehicle cool down before removing the heater core. When the heater core is cold enough, start working on its hoses. There are two hoses attached to your heater core: one that lets the antifreeze in and one that lets it out. You can remove the hoses easily by getting rid of their clamps; however, if they don’t have clamps, just go ahead and cut them.
Step 3 – Connect the hoses. -Link the hoses together using a hose connector or coupler. Attach the two ends together. This should make a short loop of tubing for the antifreeze, thus bypassing the heater core.
So, “What happens if I bypass the heater core,” you ask? Well, it provides a temporary solution to keep your cooling system working and, at the same time, prevents coolant from leaking into the passenger side. When bypassing the heater core, keep in mind that the heater and defrost system will not be functional. Both systems will only resume operation when the heater core is replaced.
Remember, bypassing the heater core is just a short-time remedy. It is still best to have your faulty heater core replaced. If you need a new heater core, you can check Auto Parts Warehouse for high-quality options sold at budget-friendly prices.
