Materials of tolerance parts: Type D pump are made of cast iron, the shaft is 45# steel.
Type DY: The materials are divided into three types: I - cast iron(the temperature in operation is 20--150degrees)
II_cast steel (the temperature in operation is 45--400degrees)
III_stainless steel (the temperature in operation is 45--400degrees)
Type DF: According to the liquid can be divided into cast steel and stainless steel.

Q:what causes water pump failure?

Q:Water pump 07 dodge.charger?
Anytime you replace your water pump. You should replace the thermostat and gasket. Also check the upper and lower radiator hoses to see if either one of them are collapsed.It wouldn't hurt to replace the radiator cap.
Q:How do i know if my car water pump is working?
It doesn't have to leak from the weep hole to have a bad shaft bearing in your pump. This won't affect your pump's ability to create a flow. Warm your car up and see if coolant ever moves or if it just stays put or comes out of the cap. You may just have a bad thermostat or a clogged radiatior (internally clogged).
Q:Thermostat or water pump problem?
Either the water pump... Or it could be the radiator that might not be performing as well.

Q:The water well pump is surging water pressure is dropping and keeps tripping the breaker?
The pump either needs repairs, or to be replaced. It's not the kind of thing you can really do yourself unless you know how to work on pumps. And if you knew that, you wouldn't be asking. Call a professional.
Q:Ford Focus 1.6 Petrol Water Pump Problem ***HELP***?
well you will need a new pump, but im wondering why they are advising you to get a camber kit. camber kits are for the slant of how your wheels touch the ground i.e When the bottom of the tire is more inwards and the top is out, that is referred to as positive camber. Positive camber wears the outside of the tires at a rapid rate. Positive camber is generally the result of a bad alignment or wearing ball joint. A camber kit is not usually required for this because replacing the faulty part and realignment generally pulls everything into spec. One time a camber kit will be needed for positive camber is when the vehicles ride height is raised. When it is raised, it puts stress on the top ball joint because the wheels lifting motion conflicts with the ball joint position therefore pushing it to the side. With an adjustable camber kit, this is corrected by sliding the ball joint back inwards, towards the motor, to bring the wheel back into spec. they will of needed to look underneath your car to diagnose the problem. but i would take it to another garage to get them to diagnose the problem. i hope this helps man.
