How do you change a water bypass hose in a 1998 oldsmobile intrigue?
You have to remove the tensioner assembly, not just the tensioner pulley, but the whole assembly, in order to access the plastic bypass hose. Be very careful, as these pipes get old, the plastic becomes brittle, and possibly the flange end will break off and remain in the block when you remove the pipe, check the block opening carefully to remove all of the remaining flange. Also, be very careful when removing the lover pipe nipple into the engine block, if you try to pry the tensioner assembly off the block, you will probably snap off the machined nipple that locates into the block, Ask me how I know!!! Good Luck, it can be done but you need to move carefully and deliberately. (by the way, a rebuilt tensioner assembly costs about $80 US, the pipe is about $6.
