wbain is my hero. Anyone who says that replacing a 103 water pump is easy is a really good tech! Also, he must own the SnapOn FLXM13 thin shaft flex socket that will ease this job quite a bit.

I find this job a little challenging. It's not impossible, just hard to get at the three bolts and getting the tensioner out of the way is a little extra work beyond that. I have read that the pump can be changed without removing or loosening the tensioner, but I couldn't figure out how to do it.

I would highly recommend that you change the short hose between water pump and thermostat housing (I think that's where it is) because it is difficult to change otherwise. That makes it a good investment of a few bucks IMHO.

Good luck,
