How do I know if my water pump is reverse rotation?

How do I know if my water pump is reverse rotation?

Water pump pulleys running on the inside surface of the belt indicate a Standard Rotation water pump (grooved side of belt). Water pump pulleys running on the outside surface of the belt indicate a Reverse Rotation water pump (flat or smooth side of belt).

What is the direction of rotation of pump?

Rotation is indicated on the head of the pump, you’ll see an arrow going counter-clockwise. This is the direction you want the pump spinning. If you turn the motor around and look at the backside and remove the cap, you’ll see a shaft located in the center.

Are water pumps directional?

Water Pump: The Difference A STANDARD rotation pump rotates the same direction of the crankshaft. A REVERSE rotation pump rotates the opposite direction of the crankshaft. Water pump pulleys running on the INSIDE surface of the belt indicate a STANDARD ROTATION water pump.

What will happen if pump rotation direction is reversed?

A common myth is that in reverse rotation, the pump causes backward flow, that is, IN the discharge and OUT the suction. In reality, a pump operating in reverse rotation because of wiring or phase change will pump in the normal direction. Now, it won’t pump very well. Its flow will be reduced, as will its head.

Do all pumps have a specific direction of rotation?

First off, let’s address how we look at a pump – the direction of rotation is always determined when FACING THE SHAFT. Centrifugal pumps are available in two options, either Counter Clockwise (CCW) or Clockwise (CW). To match the pump shaft with a drive shaft we always MATCH THE OPPOSITE ROTATION.

Where do water pumps go?

The water pump is always located near the serpentine belt, timing belt, or timing chain since it is powered by one of them. This means that it is also installed at the front of the engine. If the timing belt powers the water pump, it may be difficult to see it though. You may need to remove a lot of covers to see it.
