What is a Car Water Pump?
It is the pump in the cooling system of an automobile that cause the
water to circulate. In other words a water pump is a belt driven device found in any car which transfers water from the radiator to the engine, thereby helping to keep it
cool. The outward design of the water pump can change from one car to another,
but there are some basic similarities as a result of their identical function.
The water pump can be found near the car's front or side, behind the fan belt.
It will look a bit like an octopus, with a prominent hollow disc shape in the
center and several arms radiating outward. One arm should be attached to the
radiator; another should be attached to the engine. These are hollow pipes in
reality, where the other arms are simply for added support to keep the water
pump in place. Rising from the disc should be an axle, over which is either the
fan belt or a secondary adjacent belt.
How Does a Car Water Pump Work?
As the car engine runs, the fan belt turns,
turning the axle at the center of the water pump. The pump operates on
centrifugal force. In the center hollow of the pump is the axle on the inside
of the pump, connected to a series of vanes, which turn along with the axle.
This turning motion creates suction, pulling water from the radiator. The water
reaches the pump and is thrown against the exterior walls of the pump by the
power of the vanes which are generating the centrifugal force. As the water circles
against the outer wall, it presses down a drain, which sends the water into the
engine block. From there it passes into the cylinder heads, and drains back
into the radiator for the process to repeat itself.
How to Tell if Your Water Pump is about
to Fail?
Every water pump has something called a weep hole. The hole is just a
few millimeters in diameter and should be located on the side of the pump or
facing toward the ground. Normally the weep hole is sealed by a gasket, but as
the water pump begins to wear, the gasket will erode. As a result coolant will
begin to dribble out of the hole. This is very serious and indicative that the
water pump is no longer able to do
its job. If coolant should
leak out of this hole while the engine is idling, you're best course of action
is to head to the closest mechanic immediately. You risk overheating your
engine and doing irreparable damage to it otherwise.
Car Water Pump Problems
Car water pump failure can lead to severe car overheating
problems, and eventually damage the engine of the car. Some of the
frequently encountered car water pump problems include coolant leaks, damaged
impeller, and defective bearing. Owing to the extensive use, and the wear and
tear car water pumps are subjected to daily, it's not surprising that they
encounter these problems. Symptoms of car water pump damage include coolant
leakage, noisy engine and corroded parts. If any of these symptoms are
observed, you will have to repair the water pump at the earliest. If you feel
that the problem is beyond repair or it has been a long time since you last
replaced your water pump, you may have to take the car water pump replacement
option a bit more seriously. You may have to replace the timing belt as well,
because like the pump, the belt is also bound to be subjected to great amount
of wear and tear.
