Water Pump Replacement

Your water pump has a crucial role to play in the safe and smooth operation of your engine. It keeps coolant from the radiator in circulation around all the different parts of the engine, removing excess heat and keeping the temperature constant. Running your engine with a failed or leaking water pump can very quickly cause severe problems, even a seized engine. If you suspect your water pump is failing, don’t delay, call in the experts right away and save yourself time and money. The AutoMend network of vehicle repair and maintenance specialists covers the whole of the UK, and our trusted garages and mobile mechanics are always nearby to help you in your hour of need. Our members are located in all parts of England, Ireland, Scotland and Wales, so whether you need a routine water pump repair, or an emergency water pump replacement, call on us and we will get you back on the road.

Understanding Water Pump Problems

Because your water pump is so critical to engine temperature control, it’s never a good idea to drive if you are aware that it is faulty. There are a number of signs of a faulty water pump to look out for, so if you see any of these, don’t drive your vehicle. Either call out an AutoMend mobile mechanic to get your vehicle fixed, or get your vehicle towed to your nearest garage. A water pump replacement is a lot cheaper than repairing an engine damaged by overheating.

Leaks

A leaking water pump may leave a pool of either clear water or bluish liquid on the ground under the middle of your engine. This is your engine coolant, and the bluish colour is caused by additives such as antifreeze.

Noises

A failing water pump often develops a noisy bearing, which can be heard as a high-pitched buzzing or whining when the engine is running. If the drive belt is loose or slipping (or even over-tightened) this may be a source of noise and should be investigated. A loose belt will make the pump inefficient. An over-tightened belt may damage the pump bearing, leading to early failure.

High temperature

You should always periodically check your temperature gauge when driving. If you notice the engine suddenly beginning to run hotter than usual, it is time to consider that the water pump may be beginning to fail. Get it fixed at this point, or you may find.

Steam

If you see steam coming from around the lid of your engine compartment, you are in real trouble. Either the water pump has completely packed in, or your radiator is damaged. Either way, once you get to this stage, engine damage may already have occurred, or you are well on the way to a seized engine.

Answers to your questions

What is my water pump and what does it do?

Your water pump is a mechanical pump, which uses centrifugal (circular) force to pump coolant from the radiator around the engine and back again. In essence, the pump consists of a belt-driven hub, which is attached to a bearing, which in turn drives an impeller. The impeller is contained within a housing, which is attached to the engine block, and sealed to make it water-tight. There are many different designs of water pump depending on the make and model of your car, but they all work in basically the same way

The pump has two hollow tubes, one of which is attached to the engine and the other to the radiator, to carry the coolant. The belt that drives the hub can either be the car’s fan belt, or another secondary belt, which provides the circular motion to drive the pump.

Once the engine is running, the fan belt or the secondary belt turns the hub, which turns the impeller (a series of vanes along an axle). The turning motion causes suction, which pulls coolant from the radiator along one of the hollow tubes. Once the coolant is inside the pump housing, the power of the vanes pushes it against the outer wall, where it circles around and out of a drain. From the drain, the coolant goes into the engine block through the other hollow tube, and into the cylinder heads, cooling as it goes. The coolant finally drains back into the radiator, and this process continues all the time the engine is running.

How long will my clutch last?

Your clutch relies on friction to operate, and it has lots of moving parts. For this reason, a clutch is designated as a 'wear part' which means it will need to be replaced at some point in the life of your vehicle. Under normal circumstances, a clutch can be expected to last around seven years. There are many factors that will reduce the life of a clutch. Driving with your foot resting on the clutch pedal (called riding the clutch) is a sure way to burn out a clutch more quickly. Aggressive driving involving lots of acceleration is another. Even city driving, where there is a tendency for slow-moving start/stop traffic, and lots of gear changes, can cause your clutch to wear out faster.

How long will my water pump last?

As with any mechanical component of a car, the water pump is made from long-lasting materials, but will wear over time. A water pump is not expected to last for the full life of your engine and will need to be replaced at a certain mileage. The replacement interval for a water pump will vary depending upon vehicle type and manufacturer, but it can usually last from up to 60,000 miles, to much as 120,000 miles in some models.

Manufacturers recommend that when your vehicle is ready for a timing belt or cambelt change, that the water pump is also replaced at the same time. There several reasons why it is recommended that timing belt and water pump replacement go hand in hand. The first is that both components tend to wear at a similar rate, so replacing one will almost certainly coincide with replacing the other. The second reason is one of cost and convenience - both replacements involve stripping down the engine to complete the task, so it makes sense to replace both items at the same time to save on labour costs. The third reason is that the water pump is critical to your engine, as a faulty pump can result in major engine damage, so a policy of replacement before failure can save you massive repair costs at a later date.
