How to Know If Your Cadillac Escalade Water Pump is Faulty
Out of the many problems that can happen to your car, water pump failure can be one of the worst. Basically, it's the one in charge of pumping the coolant and water to the engine so that it won't overheat. It can be a hassle if the Cadillac Escalade water pump becomes faulty, which is why here are some troubleshooting tips to help you diagnose if you should have it replaced already.
The usual cause of a faulty water pump is a broken bearing on the pump shaft that has a leak. This can be seen seeping from the weep hole, which is located at the bottom of the water pump. You can also inspect the gasket that's found behind it. Take note that you won't be able to notice that the water pump is leaking once the engine is off, so you have to ensure that it is on before working on it.
Loose pump shaft
Oftentimes, the reason why the bearing gets worn out is because of a loose pump shaft. Locate it and grab the fan and start wobbling it. If it moves, then it's an indication that the shaft is broken. This must be replaced immediately to avoid damaging the water pump.
Signs of leak
This troubleshooting technique is a good way to know if your water pump is leaking. Have your Cadillac Escalade parked on a concrete surface, preferably inside your garage. Place a white or light-colored cardboard directly underneath the motor. When morning comes and you find out that the board is wet, then the water pump is indeed leaking.
If you hear any odd noises coming from under the hood, then there must be something wrong with the components. A low-pitched grinding sound indicates that the bearing is worn. Have this replaced immediately because it can affect the water pump.
Thermostat warning light is on
You can check the warning lights on your dashboard to find out if the parts under the hood are still okay. If the thermostat warning light turns on, then it's an indication that your vehicle is not getting enough coolant because the water pump is leaking.
