hi I own a 2002 buick lesabre 3800 series 11. my so called bypass pipe which is connecting my water pump and intake manifold was leaking, i ripped it off and cleaned out the old gunk, now im trying to replace it but it wont go in. I thought u could just put it on but the part that goes into the water pump wont fit no matter how hard i try. I even broke one trying to push it in. please tell me how do i replace the bypass pipe...do i have to take of the alternator for it to fit? helpppp

:confused:

Actually the 90 degree plastic elbow (bypass) goes between the lower intake manifold and tensioner assembly not the water pump itself on a Series II 3800 engine.

In addition to the alternator you will need to remove and/or set aside the tensioner assembly in order to remove and or properly replace the 90 degree coolant elbow from the tensioner and lower intake manifold. Also, there are two o-ring seals that should be replaced on the elbow. The elbow from a GM dealer or AC Delco supplier has the o-rings with it.
