KHE Posted September 22, 2012 Report Share Posted September 22, 2012 I received a call from a friend who has an '87 Allante with the 4.1 engine and he is in the middle of replacing the water pump. He can't get the pump off and says there is a pulley blocking it. I am going to help him tomorrow and wondered what the torque values are for the pump bolts, pulley bolts, etc. As I recall on the RWD platform with the HT-4100, there is a vacuum pump that needs to be removed but it has been so long sonce I worked on one of those engines, I can't remember.

Thanks for the offer but we completed the job back in September and I forgot to post back. All is well - no leaks.
