It’s always a good idea to keep your cool, and that’s especially true when it comes to some components of your vehicle.  One is the engine.  It’s hot under that hood thanks to the mini explosions that are occurring in the internal combustion engine when it’s running.  Your vehicle has a cooling system which takes the heat out of the engine by moving a liquid coolant to a spot where the heat can escape (the radiator). 

The part that keeps that coolant moving is the water pump, which could probably be more accurately called the coolant pump since water is only one component of the fluid that does the cooling. If the water pump fails, your engine can overheat quickly, and that can cause significant and expensive damage to your vehicle.  Water pumps can be driven by belts (mechanical) or electricity (electric).

Your vehicle’s manufacturer recommends mileage intervals when you should consider replacing your water pump even if seems to be working fine.  That way   you are less likely to have a water pump break down at an inopportune time. Some manufacturers recommend replacing it every 60,000-100,000 miles/100,000-160,000 km.

Sometimes your water pump will fail before that, of course.  One sign something is wrong with the cooling system is if you notice the engine is overheating.  An illuminated engine temperature warning light on your dash or a temperature gauge that shows above normal are two things to look for.

You may also see steam coming out of the engine compartment, which is another sign of overheating.  Both could mean your water pump needs replacing.  We also recommend that when your vehicle’s timing belt needs to be replaced that you have the water pump replaced at the same time since everything will already be apart.

When your vehicle is already in to have the water pump replaced, it’s a good time for a technician to examine other cooling system components at the same time.  Those will include belts, pulleys, hoses, clamps as well as the radiator, thermostat and heater core.

Your vehicle is like you in a way.  When it gets hot, it needs to be cooled down.  And one of the key parts to keeping it cool is the water pump.

Now, that’s a bit of a misnomer.  It IS a pump, but it’s pumping coolant, not pure water.  Cooling off your engine is vital since it builds up heat when it creates power by burning fuel.  Your water pump acts as a way to recirculate that coolant.  It goes through a series of tubes and hoses through the engine where it picks up heat, then is sent off to the radiator to get rid of that heat.  Cooled off, the coolant is recycled through the water pump to start the journey again.

The water pump works by taking mechanical power from the engine, usually from a belt.  Obviously, that belt has to be in good condition and adjusted properly or else the water pump won’t be able to do its job.

Here are some things to look for that will signal problems with your water pump.  If your heat gauge is erratic or showing a much higher than normal temperature, that could be a sign of trouble.  Another is if you hear a whine under the hood.  And if that gets louder when you go faster, get it checked right away.  You may see steam coming out from under the hood or coolant may be leaking. 

These signs signal that it’s time for you to have a technician check to see where the problem is. Some water pumps are powered by a timing belt.  If your vehicle has that design and your timing belt is due for replacement, sometimes it’s a good idea to replace the water pump too, even if it’s working properly.  That’s because the labor to replace the timing belt can be expensive and it may be wise to proactively take care of the water pump while it’s disassembled.

Your service advisor will explain the options available and offer the best path to keeping your water pump doing its job.  Your engine’s life depends on it.

No matter what the temperature is outside, it’s important for your vehicle’s engine to remain cool, calm, and collected.  Well, cool, anyway. If your vehicle has a gasoline engine, it’s powered by a bunch of explosions involving spark plugs, pistons, gasoline, and air.  And the by-product of all those things working together? HEAT.

There’s a whole cooling system to keep everything at a tolerable temperature for your engine’s parts, and a key part of that is the water pump.  Technically, it’s pumping more than water. It should actually be called the “coolant” pump since the liquid that circulates through the system is a mixture of water and coolant. 

Basically, the water pump keeps this coolant moving through your engine, where it picks up the engine heat, and then is pumped into the radiator where it gets rid of that heat.  When a water pump fails, the engine heat can build up.  When you get a warning light on the dash (either a gauge or a light) that shows the temperature is too high, it could mean a bad water pump. 

They can fail for many reasons. They have bearings in them that wear out, as does the seal between the pump and the engine. They’re often driven by a belt or chain that can go bad.  Corrosion can spell the end of a water pump, too. 

If a technician determines your water pump has failed, it’s time to replace it. In addition, other components of the cooling system will be inspected.  The best way to avoid a water pump failure is regular maintenance of your cooling system which includes regular draining and flushing of the coolant. 

Just like it’s important for you to keep your cool, the same goes for your vehicle’s engine.
