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.

The water pump only operates when the engine’s running. Water 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 water pump either works or it doesn’t, you need to change it when it fails. Water 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 water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can you tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump – it’s got a problem. If you can see coolant in that area, you’ve got a leak.

Some water 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 water pump with a brand spankin’ 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 water pump gives out. They will all wear out eventually. Your service technician can get you back on the road and on with your life.

Radiator flushing is a necessary part of your vehicle’s maintenance. Cooling system failure is the leading cause of mechanical failure while driving on the highway. And if your cooling system fails, your engine and transmission could suffer major stress-related damage.

A standard drain and fill replaces only about half of the contaminated coolant. A Radiator Flush Service removes contaminated coolant and replaces it with fresh coolant helping to prevent future engine cooling problems.

Often problems with overheating can come from other areas as well; whether it be the water pump, heater core, or even within the engine head or head gasket. We offer diagnostics, service, and repair for all problematic areas of your vehicle.

The benefits of a Radiator Flush Service:

  1. Provides the best method of factory recommended cooling system service.
  2. Protects against coolant contamination.
  3. Removes rust and scale deposits that can cause overheating and breakdown.
  4. Protects against cooling system leaks.

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common, it is easy to prevent.

The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then goes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it’s back to the engine again.

There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is a mixture of water and antifreeze. The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage.

Another very important coolant issue that is often overlooked is the age of the coolant itself. Antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and other parts from rust, scaling and corrosion. Old coolant may still keep your engine cool, but it won’t protect it from corrosion.

If you see a warning message to check the coolant or if the temperature gauge is in the hot zone your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious. Remember four things.

First, you never want to open the radiator pressure cap. You could be severely burned.

Second, try to get to your Austin service center at Amazing Auto Repair and Transmission immediately if your coolant is low. If that is not possible, follow the directions in your owners manual – it will direct you to only make additions to the coolant overflow bottle.

Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your Amazing Auto Repair and Transmission service center where we can make necessary corrections.

Fourth, not all cars use the same type of antifreeze. You need to check your owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to rely on your Amazing Auto Repair and Transmission service center in Austin to do things right.

Remember, your Austin service center has the equipment to change your coolant quickly and inexpensively.
