Automotive Cooling System Repair & Maintenance in Denton TX

A car engine runs best at a high temperature because a cold engine adds wear to its components faster and the engine becomes less efficient. More pollution is emitted from a cold engine as well. However, your vehicle still needs a cooling system to help disperse excess heat so the engine doesn’t overheat and can warm quickly, then maintain a more constant temperature.

When the engine coolant is at about 200 degrees Fahrenheit (93 degrees Celsius), you’ll find that the engine runs at an optimal level based on the heat of the combustion chamber, the viscosity of the oil, and the slowed wearing of metal parts. Your car could use a liquid cooling system or an air cooling system, but most cars use liquid coolant.


When your car starts to overheat, you most likely have an issue with your cooling system. However, there are a number of parts that make up the system, and you should contact a coolant system expert to help you determine where the problem lies. The diagnosis could show issues in a variety of areas, including:


  • Plumbing – Your car has a series of tubes and pipes that process the coolant fluid through the car’s engine.
  • Fluid – This is the main component used for cooling, and perhaps the easiest to resolve, if your coolant fluid is running low.
  • Water Pump – This part of the cooling system is connected to the crankshaft by a belt and circulates the fluid.
  • The Engine – Consisting of a main block and cylinders, there are a number of passageways that allow the flow of fluid to critical areas of the engine.
  • Radiator – This device is tasked with transferring heat from the hot coolant to air that is blown through it by a fan.
  • Pressure Cap – This works like the seal on a pressure cooker to increase the boiling point of your engine coolant.
  • Thermostat – It measures temperature, just like the thermostat in your home, and allows the engine to heat up quickly, then maintain a constant temperature.
  • Fan – Assists the thermostat in maintaining a constant temperature in your engine.


Each of these parts of your cooling system is essential to the continued functionality of your car, and any one of them being faulty can be detrimental. If you suspect there is a problem with any aspect of your vehicle’s cooling system, contact Spenser’s Quality Automotive for an appointment. Our skilled technicians will inspect the cooling system for leaks and other problems and make sure that anything which could be leading to your car overheating is repaired properly and in a timely manner.
