What is a water pump friction wheel?
Description. The Dayco friction wheel is a component developed to transmit power from the crankshaft pulley to the water pump pulley. The main advantage of the friction wheel is the ability to switch on the water pump, via an electromechanical actuator.
How does a Mini Cooper water pump work?
The water pump has what looks to be a belt around the pulley but is actually rubber bonded to the outside. The water pump is turned by a metal wheel driven by the crankshaft pulley – this wheel is what transfers the motion of the crankshaft to the water pump.
How does a friction pulley work?
The friction wheel is in constant contact with the crankshaft pulley, but with the use of an electric motor the pulley’s radial movement is altered, and the rotating friction wheel comes into contact with the surface of the water pump pulley, bringing it into operation.
How much is a water pump for a Mini Cooper?
between $728 and $844
The average cost for a Mini Cooper water pump replacement is between $728 and $844. Labor costs are estimated between $387 and $489 while parts are priced between $340 and $355.
Why is my mini losing water?
Common sources of leaks are the thermostat housing and the radiator. You need a garage to pressure test the system. They can also check for exhaust gases in the coolant which may indicate head gasket failure. Chances are that it’s a leak rather than the head gasket.
Is there friction in a pulley?
In reality, friction is bound to be present between the pulley and the rope: static, if no slip; kinematic, if the rope slips over the groove of the pulley.
What forces are used in a pulley?
The force of gravity will pull directly down, and the normal force will pull in the opposite direction of the force of gravity equal in magnitude. Tension will pull to the right in the direction of the pulley clockwise.
Why is my Mini Cooper overheating?
Some of the most common issues that cause engine overheating, particularly in MINIs or BMWs are: low coolant levels (possibly due to engine leaks), radiator malfunction or failure, or water pump failure.
Do MINIs have head gasket problems?
Mini Coopers are powerful vehicles that offer superior performance. They might be small in stature, but they make a bold statement. Even though they are reliable, they are still known to have head gasket issues. Like any other vehicle, your Mini needs regular maintenance performed to keep it running smoothly.
Can I put water in my Mini Cooper coolant?
The type of coolant you should use for your Mini Cooper is a 50/50 mixture, 50 percent antifreeze and 50 percent water. If your antifreeze is more than 3 years old, discard the old coolant and purchase a fresh container.
