#4 of 5 Plastic Impelled Water Pumps by frumunda Mar 04, 2009 (6:17 pm)
For those of you who have had the misfortune of dealing with the "plastic impeller on the water pump" issue, there is an upgrade. GMB makes the reman water pump to cure that ill. It is the original pump casting but with a new STEEL impeller. BMW and Mercedes have also been those nasty culprits that enjoy putting the plastic in their cooling systems. Its my opinion that it my be a German thing.
#5 of 5 Help with 97 Grand Cherokee bypass hose on water pump by lunytnz May 11, 2009 (2:38 pm)
I'm trying to replace the water pump on my 97 GC with a 5.2 V8. I have everything removed from the old pump except the bypass hose (a 1" dia hose about 4" long, from the top of the pump to the block). I can't move the hose clamp up the hose because there's not enough room under the big aluminum bracket that the AC compressor and alternator are mounted to. I tried removing the big aluminum bracket, but can't get it. Maybe I'm missing a few bolts, maybe behind the water pump? I would like to replace the bypass hose while I'm in there, but I will definitely need to remove the bracket to do that. Any help would be greatly appreciated! What I thought would take a few hours has already taken much longer and I don't even have the old pump out yet!
