The cooling system in your diesel engine is designed to reduce the temperature of the engine by diverting the excess heat to the radiator, where it is then burned off in the atmosphere. The system uses a water pump to circulate the coolant throughout the engine by moving it through various channels. It collects heat generated by the combustion process, passes it to the radiator and repeats the process until you eventually change the coolant.

The coolant system needs regular care and maintenance or you will run into problems under the hood. In addition to changing the coolant on a regular basis, you may need to replace certain coolant components that help deliver the coolant, including the water pump, coolant temperature sensor, the tubes moving the coolant, and even the radiator. Without a steady stream of coolant, the engine will start to overheat and the damage will spread to other crucial components, leading to costly repairs that could otherwise be avoided. 

We sell a wide range of replacement coolant system parts at Bostech Auto to help you keep your engine cool. You may need to replace the water pump if the coolant isn’t reaching the intended destination. Check the coolant temperature sensor to see if the coolant is able to deliver the heat to the radiator. Inspect the coolant hoses and bypass systems that keep it flowing. Keeping your engine the right temperature takes more than a coolant change. Browse our selection of replacement coolant system parts to prevent your vehicle from overheating.
