LONG VS. SHORT WATER PUMP

“Hub height” is the industry term for measure a water pump’s height. The hub height is a critical belt-alignment dimension determining where the water pump pulley belt groove(s) fall in relation to your crank, alternator, power steering pump, and air conditioning pulley grooves. The dimension from the mounting gasket surface to the outside face of the hub (where the pulley is bolted) is the hub height.
