Timing Belts have come to replace timing chains. The serpentine belt (timing belt) ensures that the crankshaft, valves, and motor pistons are operating in unison. Timing belts are more efficient than chains. But, why should you be worried about water pumps & timing belts at the same time? READ MORE BELOW
Why replace a Water Pump & Timing Belt at the same time?
Both of these engine components are essential to the proper operation of the vehicle. They will both need periodic replacement. This only applies to vehicles with a timing belt, timing chains do not need to be replaced. How do these components work together? In most cases, each timing belt drives the water pump. You will want to consulate your vehicle’s owner’s manual on the schedule for changing out your water pump & timing belt. What you will typically find is that the schedules are pretty much on the same time frame.
How does the water pump work?
When an engine is running it will generate high temperatures. Heat must be redirected and mitigated properly. A motor must be kept at an optimal temperature. An engine that is not kept at the optimal temperature can suffer catastrophic failure. Most vehicle’s water pumps are driven by a timing belt. The timing belt is driven by the motor. Water and fluids are circulated around the motor and flow back through the radiator thus cooling it. An engine’s water pump also facilitates circulating the coolant (such as antifreeze) through the heater core so that the cab of the vehicle can stay warm in winter.
Since the water pump’s action is controlled by the motor’s activity, the flow rate of fluid is controlled by engine RPMs. Your vehicle’s thermostat essentially helps regulate the flow of fluids based on the engine temperature. As the temps increase so will the rate of water flow. This helps your vehicle maintain proper temperature. The water pump & timing belt work in tandem to help regulate this process.
When Should Your timing belt be replaced?
If your timing belt were to break it would mean that your engine would immediately stop. Most manufacturers provide a suggested time frame for repalcement. But, to know more about Signs and symptoms of a bad timing belt check out our article HERE!!!
