i changed water pump last night with a brand new water pump from napa. i bolted it all on and was bolting the brackets etc on. put the timing belt back on and the tensioner pulley bolt that bolts to the waterpump is a different bolt from the one that came outof the origanal/bad water pump. i have 2 old pumps off my other 1.3 engines and both bolts are the same as each other but different than the new one that is bolted on. i went and got the same size bolt but metric thread and it is still to big. anyone know what size/thread this bolt is? all the fastener places are closed and suzuki is also. i am dealing with napa now.
