Thermostats do have a limited lifetime and, in fact, are changed as a matter of course, as a precaution and as cheap insurance, whenever major work is done on the cooling system.

What are the functions of a water pump thermostat?

Like any thermostat, the circulating pump thermostat is used to regulate the temperature of the hot water and turn on and off the pump as necessary to ensure that hot water is appropriately flowing through your home without expending unnecessary energy.

What are the symptoms of a bad water pump?

A bad water pump will make a grinding or loud rattling noise like marbles hitting each other. This is due to a bad bearing inside the water pump. When this happens, the water pump pulley will start to wobble and eventually, the belt can slip out of place. Another symptom of a bad water pump is overheating.

What are the signs of a failing water pump?

Another sign of a bad water pump is a loss of coolant. Typically consisting of a 50/50 mixture of distilled water and antifreeze, coolant is the “blood” of a car’s cooling system. When the coolant system works as it should, no coolant should escape due to its closed design. But a bad water pump may cause coolant to leak from its gaskets and seals.

What happens if water pump is not working?

When the water pump fails completely, it will not be able to circulate coolant through the engine block. This results in an overheating situation and if not repaired or replaced quickly, can cause additional engine damage like cracked cylinder heads, pushed head gaskets, or burnt pistons.

When to replace a water pump in a car?

The cooling system thermostat should be replaced at the same time as the water pump particularly on a 20 year old car and particularly if the thermostat has never been replaced. Finally, all rubber coolant hoses, including heater hoses, should be carefully inspected for any rot, weakness, cuts, oil saturation or other damage.

Why is the car cooling system called a water pump?

The water pump circulates liquid coolant within the cooling system of a car engine; see the diagram and read more on how it works below. It’s called a water pump because in the early days of automobiles engine cooling systems were filled with water. Modern cars use a special fluid called antifreeze or coolant . Water pump.

How does the thermostat work on an engine?

To do this, the thermostat will start off in the fully closed position – blocking any coolant flow into the radiator where it would lose heat. Instead, the coolant is redirected back into the engine block to ensure it reaches its ideal temperature (around 190 degrees) sooner – regardless of how hot or cold the outside air is.

Where does the coolant go in a water pump?

The water pump moves the coolant through the coolant passages that are located in the engine. The coolant helps keep the engine temperature low.

How does coolant work in a car radiator?

The coolant helps keep the engine temperature low. The flow of coolant is held back by the thermostat until the coolant reaches the desired temperature, when the thermostat opens up and allows the coolant to flow through the radiator hose into the radiator.

What happens if your car thermostat is stuck closed?

Learn more… Your vehicle’s thermostat opens to allow coolant to flow through the radiator and cool the engine down. However, if the thermostat gets stuck in the closed position, the coolant can’t flow through the radiator and can make your engine overheat.

Can a sutck closed thermostat cause a water pump failure?

A sutck closed thermostat will block coolant circulation and overheat the engine, as well. One way to check for worn out or failed pump bearing is to check for water pump shaft movement. 1. With a faulty bearing, you can often hear a squealing, howling, or sometimes a grinding noise coming from the front of the engine.

Why is my water thermostat boiling coolant?

Look to the pulley that drives the water pump. If there is a stream of coolant running down below that pulley, its pretty likely the water pump. Same for the thermostat housing. Both can fail without actually leaking, especially the thermostat causing the coolant to boil over.

Bypass returns are generally short in length and are often considered a “fifth hose”. Although not commonplace, some engines such as this BMW V8 position their coolant bypass pipes internally in difficult-to-reach locations.

Where are the radiator and heater hoses located?

Radiator and Heater Hoses In a typical automotive cooling system, you’ll find at least 4 main hoses. First, the upper radiator hose leads directly from the thermostat housing (on the intake manifold or cylinder head) into the top of the radiator. Attached to the bottom of the radiator is a lower radiator hose.

What do you need to know about cooling system hoses?

In order to withstand the vibration and movements of the engine without breaking, cooling system hoses must be flexible. To achieve this, traditional (and OEM) coolant hoses feature outer layers made of a durable rubber compound. Underneath the rubber outer layer is a flexible fabric reinforcement mesh.
