As the mornings have grown colder, I’ve noticed my heater isn’t putting out hot air. With winter approaching, I’d like to get this fixed soon.

Cold-Mornings-Car

The method used to warm a car’s cabin isn’t very different from the one used to keep the engine cool. In fact, it’s all hooked together and runs on the same circuit. Coolant circulates through the engine and absorbs engine heat, which is exchanged with the outside air by way of the radiator. A much smaller radiator called the heater core uses the same hot coolant to keep the cabin toasty. In general, there are two things that can go wrong with this setup.

Here are the two main culprits of reduced heat output in your vehicle’s cabin:

1) The first item to check is the engine temperature. To help cold engines warm up fast, the flow of coolant is restricted by way of the thermostat—a thermal valve that opens when it’s hot and closes when it’s cold. When the thermostat wears out, it remains stuck open or shut, which leads to either overheating or cool operation.

A worn-out thermostat might be preventing the coolant from getting warm enough to heat the cabin. Replacing the thermostat can be a 20-minute job or a real hassle. Check your service manual to see how involved the replacement is or stop by any of our 5 convenient locations in the Reno-Sparks area.

2) If the thermostat is fine, the flow of coolant in the heater core may be restricted by built-up goop. Sediment and grime can accumulate between coolant changes and collect in the heater core.

A flush can be done by disconnecting the heater hoses at the water pump (when the car is cold) and using compressed air to push the coolant and gunk backward, out the inlet hose. Be sure to capture all the old coolant and dispose of it properly. Follow that with a few rounds of filling the core with tap water and flushing it out in the same way, then refill the core with mixed coolant and reattach the hoses. None of these fixes are hard, but the heater-core flush is messy, so you might want to take your car to a shop for service.

Properly maintaining the cooling system is key for the heating system of your vehicle to work efficiently. Having the coolant in your engine flushed regularly and re-filled with the clean coolant/water mix is very important along with repairing any leaks that occur in your cooling system. We recommend having your cooling/heating system inspected on a regular basis with each oil change, so that you are aware of any issues and can have them repaired while they are still small.

The hot summer heat is never easy on a vehicle and can lead to overheating and damage to your radiator and engine if not taken care of properly.

Your vehicles cooling system is what keeps your engine at the proper temperature. If the engine is too cold, it emits more pollutants and engine components can wear out quicker. If the engine is too hot, it can cause serious damage, or even stop working completely.

Visit Sierra Car Care and MST Tire Center today for your FREE COOLING SYSTEM INSPECTION before the heat wave hits ($27 Value). Offer ends July 31, 2014.

At Sierra Car Care and MST Tire Center, one of our ASE certified technicians can thoroughly inspect your cooling system for any malfunctions. If any parts are worn out or need replacement, our technicians can quickly and efficiently take care of that for you.

Description of Cooling System

The cooling system primarily consists of:

  • Cooling Fan
  • Water Pump
  • Thermostat
  • Radiator
  • Heater Core
  • Heater Valve

and various other parts that primarily work together to dissipate and remove heat from a vehicle’s engine.

The antifreeze is also responsible for keeping other engine fluids from boiling or freezing. After the antifreeze flows through the engine, it cycles back to the radiator, where the excess heat escapes through the radiator’s walls. The antifreeze is cooled by the cooling fan and readied to be re-released into the engine to dissipate additional heat.

Benefits of Cooling System Repair

Over time, antifreeze breaks down and loses its efficiency. If not drained and replaced, old antifreeze can lead to corrosion.

During a cooling system flush and fill, our staff will drain the antifreeze from the radiator, flush the cooling system, and fill the radiator with  new antifreeze.

Proper cooling system maintenance will help keep your vehicle running cool all Summer long.

Cooling System Inspection Includes: 

During an inspection of the cooling system service, our experts will check the cooling fan for damage and the fan belt for cracks. Because the radiator is responsible for cooling the antifreeze as it circulates throughout the cooling system, a leak or a broken radiator hose can lead to major engine failure.

A radiator pressure test is one way we can check for potential leaks or radiator damage.

Ultimately, neglecting basic cooling system and radiator maintenance can lead to a potential radiator replacement and major engine or radiator repairs down the road.
