Damage to related components like chain guides or a chain tensioner will also produce noises like whining or buzzing. It’ll trigger your dashboard check engine light and likely store a timing-related trouble code, like P0011 or P0012 - depending on which timing component prompted the warning.Įngine noises: A loose or damaged timing chain often makes a rattling or whirring sound. Ensure your car engine doesn’t overheat by starting the engine and monitoring the temperature gauge.What Are The Symptoms Of A Defective Timing Chain?Ī faulty timing chain will cause your vehicle to exhibit one or more symptoms.Īn illuminated check engine light: If your timing isn’t running right, your engine computer will detect this problem at some point.Finally, bleed the cooling system and refill it with coolant according to the manufacturer’s instructions.Reinstall the pulley bolts and tighten them after you fix the drive belt.After you mount the new gasket or seal in place on the water pump, install the new water pump and gasket.Then use brake cleaner to clean the water pump mating surface. Remove water pump pulley retaining bolts.If it doesn’t come off easily, tap the pump with a dead blow hammer. Once done, remove the water pump slowly.Unscrew the water pump bolts and the pulley.If your vehicle has a manual drive belt tensioner, loosen the lock nut before turning the adjuster screw. Next, rotate the automatic tensioner to remove the drive belt.If the pulley starts to spin, put extra pressure on the belt tensioner to hold it in place. Use a ratchet or a wrench to loosen the water pump pulley retaining bolts.Proceed to drain the old coolant by lowering the radiator hose (safest method) or opening the radiator drain petcock.Place a fluid catch pan under your car before you remove the radiator cap. Raise the car using a jack and jack stand.Disconnect the battery and wait until the engine cools down.Here’s how you can replace the water pump: So it’s better to call an expert to help you replace or repair the water pump system. How To Replace A Water Pump?Įach engine model may have its own belt drive system or water pump replacement steps. It does so to absorb the heat that increases with engine speed - ensuring that the engine maintains normal temperatures. However, the water pump adjusts its speed according to how fast the engine runs. Usually, the water pump can move around 7500 gallons every hour. The coolant absorbs the engine heat before it travels to the radiator, which cools the coolant again. This force creates a suction that allows the pump to receive coolant from the radiator and send it to the engine. When you start your engine, the fan belt and the water pump’s central axis also begin to turn - creating a centrifugal force. This protects the engine and other essential parts from overheating. The water pump plays a key role in your vehicle’s cooling system by circulating coolant from the engine to the radiator. That’s why experts advise replacing the water pump when you get your timing belt changed. You can find the water pump underneath the timing belt. What Is A Water Pump?Ī water pump is a mechanical impeller pump which is a device used to increase the pressure and flow of fluid. Here are some of the most common queries about water pumps and water pump replacement cost, as well as their answers. A bad radiator or air bubbles can also cause inconsistent temperature readings. Fluctuating fluid gauge: If your temperature gauge needle oscillates between normal and high, your car’s water pump may be the culprit.You can also check for frothy oil on the oil dipstick for possible internal leaks Fluid leaks: Green, orange (rusty coolant), or red-colored coolant may leak out when water pump components develop cracks or wear out.Abnormal noises: A loose accessory belt, pulley, or worn-out bearings in the water pump cause squealing and whining engine sounds, especially when accelerating.Radiator steam: Steam billows from the engine as the coolant can’t circulate in an overheated radiator when the water pump malfunctions.It’s usually indicated by an engine temperature warning light or elevated engine temperature reading on the dashboard. High coolant temperature: The engine heats up without a good water pump, leading to high coolant temperatures.Here are a few signs to help you spot a water pump malfunction: As a result, a water pump malfunction is a serious issue as you’ll be looking at overheating, premature wear, and severe damage to vital car parts. The pump prevents engine overheating by continuously circulating coolant from the radiator to the engine. The water pump replacement cost should not deter you from considering the service.
