Is the jap import alternator belt the same size as the uk one? I can't seem to get one that fits as still slips adjusted to the max!

Anyone got a part number?

Nope there different due to water pump pulley size.

Think mike on here is best mate mjp.

He Will sort u out.

Z nut just learned me this so thought I'd try whoop whoop.

I dont understand hes talking about alternator belt not water pump belt i thought they were seperate i didnt realize jdm cars had diffrent pulley sizes on there water pumps

Last I checked sure there all on one belt, except air con and power steering.

 

Water pump pulleys are different sizes for sure, euro spec maybe like it for motorways and jap more in town unsure why really.

Is it the viscous fan pulley which is a diffrent size on jdm cars then not the actual water pump itself .:confused:

the viscous fan pulley is all so the water pump pulley

 

one pulley does 2 jobs

But doesnt the viscous fan pulley bolt to water pump

yep you are 100% right the viscous fan bolts on to the Pump holding the pulley in place between them

Im still confused so jdm cars use the same water pump as uk cars but diffrent size viscous fan pulleys so diffrent lenght belts yes.

Same Fan

Same Viscous

Same Pump

 

Different sized Pulley

 

Jap = Larger

UK/US = Smaller

Ok thanks got it now, was a bit confused i was thinking pulley was part of the viscous fan itself .:thumbup1:
