What to do when car is overheating, water pump, radiator?

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system:
the radiator
the radiator cap
the hoses
the thermostat and
the water pump

The water pump’s like the heart of your cooling system, circulating the fluid throughout. It’s a small pump that’s driven by the engine; usually by belt, but sometimes by a chain or gear.

Water Pump

The pump only operates when the engine’s running.  Pump failure is pretty routine. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your owners’ manual or service technician to see what’s recommended.

Since a pump either works or it doesn’t, you need to change it when it fails.  Pumps fail in one of two ways: the bearings fail or they begin to leak. It’s possible to have a leak from a cracked pump, but it usually leaks at the gasket where it attaches to the engine.

So how can you tell when the pump is failing? If you can hear a low-pitched grinding sound coming from the  pump – it’s got a problem. If you can see coolant in that area, you’ve got a leak.
Some pumps are driven off the timing belt. They might be under a plastic cover so you can’t see the water pump. Look for coolant on the driveway. If you see some, have your service center check it out.

Most timing belts need to be changed at 60,000 miles – some longer. It’s a good idea to change your water pump at the same time if it’s one of those that’s driven off the timing belt. To start with, 90% of the work’s already done with the timing belt change. And, if you don’t, and develop a leak later, you’ll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

You can replace your pump with a brand new one or with a rebuilt pump. Rebuilt will save you some money, but ask your technician what he thinks. Don’t feel too bad if your  pump gives out. They will all wear out eventually. Your service technician can get you back on the road and on with your life. Triangle 773-539-5858.
