I have a 1997 Buick Lesabre, 3.8 "K" engine. There is a water leak at a plastic fitting above the water pump, I believe the fitting is called a heater bypass pipe. It is basically a 90 degree plastic elbow that has an o-ring on both ends. To the best of my knowledge the fitting plugs into the block and into the belt tensioner."Go figure" anyway the part is under $10 and the labor is just under $300. Is there a step by step proceedure I can get for replacing the belt tensioner. If so I believe with the new plastic 90 my leak will be fixed. Any help with this greatly appreciated.
have the same problem?
