[928uk] 928 vs PK tensioner

[via 928uk]

“But I can't think of any way the original design stresses water pump, unless I'm missing something. I think there's a roundabout benefit in PK tensioner allows use of older/cheaper pump from earlier cars.”

 

I agree Adrian – pump clarification - the early 77 to 86 v the late 87 to 95 water pumps. They are exactly the same apart from the design of the boss and strengthening bracket for the small idler pulley. Because the PKT does not use the idler pulley you can use either the early or late pump type. Currently here in the States the early Laso pump new with plastic impeller is available and lower cost so the obvious choice if you use the PKT.
