We have successfully changed the waterpump ourselves thanks to the great help on this website i happened to stumble across. But now my question is how do I adjust the tension pulley so the belt isn't to tight I was told there are 4 different settings but we are not sure of what to do or which to pick. If anyone can help it would be greatly appreciated.
Thanks for your time
typically, on any car, the belts should be tense enough that if you push halfway between two pulleys, there should be about half an inch of deflection... too much more and it'* no good. shouldn't be too much less either...
