Should I be able to move the water pump pulley by hand on my GEMS efi engine??
Thinking the belt isn't tight enough, but as I don't have a belt tensioner on the system, its hard to know what is tight enough.
Have some cooling issues, and I'm not sure the pump is giving 100% if the belt is slipping.
I have heard of people knurling the flat area of the water pulley for extra grip?.....anyone got or done this to good effect?
Its also a new poly 7-rib belt, and I've already tighten it a few times.....

If you turn the pulley it should turn the engine over.
Post a photo of your belt routing - I've seen quite a few belt routes with the water pump barely deflecting the belt and this is not enough.
