How do I remove the water pump drive pulley on a 98 Cadillac Deville?
This is not the tensioner pulley or the pulley on the water pump this is the pulley attached to the engine drive. I can not get it off and I need to in order to replace the head gasket. Please help.
There are 3 bolts on the inside of the block cover, but none on the pulley itself. I have loosened the bolts on the inside as far as possible and still it will not come undone.
The center of the bolt has a 10mm bolt hole. The 10mm is the top of the bolt I don't know the actual bolt measurement.
It should have 4 bolts in the center holding it in place
Water Pumps - All You Want To Know
Water pumps are instruments, which help in movement of water from low pressure to high-pressure area. The movement could be due to pressure or suction.
Broader Categories
There are two broader categories, which provide the basis of classification. First is the positive displacement type. Here, the fluid moves from a section of reduced volume to the increased one. This ensures a regular flow in spite of the changes in pressure. However it contains a release valve to prevent severe fluctuation. The other is the dynamic one. Here, the movement of fluid relies upon its own momentum. The Dynamic water pumps can be divided into 2 parts depending upon the motion of the fluid.
Rotary Motion- Centrifugal Pump
This type of water pumps has a component called Impeller, which drives the fluid and converts its energy into pressure. The water is stored in a Pump Casing. It is essential to avoid leakage of fluid by using labyrinth seals, mechanical seals or gasket. The motor provides current for the pump to run. It is necessary to use oil to avoid friction and maintain the flow. The actual movement is caused due to the rotation of the fluid therein.
Linear Motion-Jet Pump
The jet water pumps are the most common example of the linear motion of the fluid. These do not possess any moving parts that drive the water inside it. These are also called Eductors or air ejectors. Such pumps works on the principle of creating low pressure. The movement completely relies on the changes in the fluid. But there efficiency decreases with increase in pressure. Hence, instead of pumping water they are commonly used to remove water. These make use of nozzles and a freeder stream. Although care must be given to ignite it properly otherwise it would star pumping water instead of drawing it.
In a nutshell, one can say that Water pumps work on the principle of compression or physical lifting both for pumping water and removing it. They are used in swimming pools for sanitizing the water. These also help in retaining the chlorine composition in the beach water by sucking the water vapor using these pumps.
