What is a heater core? A heater core is a device that uses coolant to heat the cabin of the vehicle. The heater core works by having coolant, already hot from the engine, pass through a small radiator (called the heater core), making the core hot. A fan blows the heat generated via the coolant into the cabin, warming the passengers.

What are signs my heater core does not work? One of the most obvious is that your car’s heater does not work, but that isn’t the only sign. Sometimes water can leak onto the floor in the passenger side, or the car can fog up the windshield quickly. Sometimes, the car may even smell sweet.

What happens when my heater core doesn’t work? Though beneficial when working properly, a broken heater core can be a major disadvantage. Cars without heat are not only unpleasant to drive in the winter, but are less valuable.

Since the heated air the core generates cools off as it is blown into the car, the heater core must be located very close to the cabin. Many times, the heater core is located under the radio or by the glove box. Due to it’s positioning, the cabin’s dashboard almost always must be taken apart to remove it.

We  recently performed a heater core replacement on a 2005 Jeep Grand Cherokee Laredo. The process begins by carefully taking off the dashboard, without damaging the plastic, radio, gauges, or wires. Though time consuming, it is crucial to take  time when disassembling the dashboard as to not break any crucial components. Once  we have  completely taken apart the dash, we can  now access to the heater core. At this point  you must be careful, as there could be coolant still in the core from previous use.

Now with access to the heater core, we remove it. The coolant is drained from the vehicle. We still have to be careful as there can still be some coolant left in the core itself. Next we remove the tubes pumping coolant into the heater core, then unbolt the core itself from the car. A visual inspection of  the core usually finds the issue. This one happens to be leaking.

Once the old heater core is removed and the new one is set into place, we run some water through the new heater core to make sure it is not defective. If everything checks out OK, it is bolted into place, then the hoses are reattached. Now begins the process of reassembling the dash. We check the electronic database to see exactly how it should be reattached, so we do not rely entirely on memory. From there we carefully attach wires, the radio, the gauges, and so on, putting the car back together again.

Auto Repair Mint Hill; Cooling System Maintenance

Auto Repair Mint Hill; Cooling System Maintenance.  I bet this time of year you are not thinking of your  Car’s Cooling System.  The truth is, this is a critical time of year for a car’s cooling system because we experience a change in temperatures that may uncover an issue that went unnoticed when the temps were warmer.  Cooling system failure is the number 1 cause of roadside auto failure.  Your cooling system consists of not just your radiator but the hoses and belts that operate them along with the coolant or antifreeze in your system.

If your car’s antifreeze is low the fluid in your engine can freeze and crack your engine block and cause a whole host of issues. But it does not stop there, look for cracks on the surface of drive belts.  These belts can be connected to your water pump, fan etc.  they need to be in good working order.  Belts  that are worn can make a lot of noise, especially in the morning.  If you hear noise coming from your engine in the morning, this may be something that needs further investigation.  Hoses are connected to your radiator and circulate antifreeze to vital components of your car.  Make sure these are not cracked or spongy, many times hoses fail from the inside out so it can be difficult to detect if you do not know what to look for.

Additionally, a bad thermostat can result in low heater output, overheating, poor fuel economy, knocking and pinging during acceleration, high idle speed or an electric cooling fan that runs continuously.  All of these things can impact your car’s performance when the mercury falls.

Performing routine car maintenance is meant to prolong the life of your vehicle and hopefully avoid major problems that can leave you stuck on the side of the road.  Setting up a schedule with a reputable auto repair facility can take the headache out of remembering when to do what and keep you on track.
