Water Pumps & Cooling Systems Repair in Ennis, TX
The cooling system in most cars consists of the radiator and water pump. Water circulates through passages around the cylinders and then travels through the radiator to cool it off.
The need to replace the various components of the cooling system – such as the water pump, thermostat, and radiator – are affected by a variety of factors. Some of these factors include your driving habits, various operating conditions, the type of vehicle and coolant being used, and of course the frequency of scheduled maintenance services like coolant changes. Possible problems with your vehicle’s cooling system may include overheating, a “sweet smell”, leaks, and the frequent need to add fluid.
A Vehicle Has Five Principal Components In Its Cooling System
- An auto radiator has a set of tubes called the “core” that the coolant flows through. Cooling fins surround the core. As air passes through the fins, the coolant releases its heat to the fins, which dissipate the heat.
- Radiator Cap
- There has to be a place to pour in coolant and the radiator cap covers that filling hole. The cap is also designed to seal the system to a specific pressure.
- Radiator Hoses
- The coolant goes from the radiator to the engine through a series of hoses that are sturdy and flexible enough to handle engine vibration and high heat.
- Like the device on your home heating/cooling system, the engine thermostat keeps the engine at the proper operating temperature.
- Water Pump
- This is the heart of the engine cooling system. It pumps coolant through the whole cooling system, and into the engine block.
