Water pump: work, service and price

The water pump is part engine your car. It is used to circulate coolant in the cooling system to lower engine temperatures and prevent overheating. If the water pump is faulty, you risk engine damage.

🚗 What is a water pump used for?

First of all, remember that your car's engine is based on the principle jogging, or a mixture of gas and air that burns at very high temperatures. Therefore, it is necessary to cool the engine so as not to damage non-metallic parts such as gaskets.

This is the role of your cooling system, which includes a water pump. It needs energy to function. This energy is generated by your motor and transmitted through the belt. Depending on the car model, this may be timing belt WHERE strap for accessories.

Thus, the water pump allows for faster circulation. coolant in the cooling system. For this, the water pump consists of a propeller connected to a pulley mounted on a bearing.

🗓️ When to change the HS water pump?

You should check the water pump as soon as you notice a problem with the cooling system. Several symptoms can indicate a malfunctioning water pump:

• One coolant leak : blue, green, orange or pink puddle under the car. This is one of the colors of the coolant.

Good to know : If the engine temperature light comes on, it could indicate a variety of other problems, such as a faulty sensor or a broken radiator. Therefore, we advise you to advance a little in the diagnosis before simply changing the water pump.

As such, your water pump needs to be replaced if it leaks, if it gets jammed, or if the propeller blades are faulty.

🇧🇷 Should the water pump be replaced when replacing the auxiliary or timing belt?

If your water pump is built into the accessory belt, we recommend that you replace it at the same time than the alternator belt. Observations are the same for the accessory belt and timing belt.

In the vast majority of cases, the timing belt is replaced after a sudden break. This often damages the tensioning rollers and the water pump. As a precautionary measure, we recommend replacing the entire distribution kit including the water pump.

Anyway, we believe thata loose belt cannot be reassembled.unless it's new. In case of tampering with the engine requiring the removal of accessories or the timing belt.

As explained above, if you observe a coolant leak, the problem may be with the water pump. This is because leakage can be from a seal or from the outlet of the water pump.
