I got somewhere around 7 years and 10k miles out of the first rebuilt one I installed in 2001, Drew. The failure wasn’t catastrophic and the leaking was evident to anyone that opens the bonnet regularly.
It’s not god awful roadside repair on a long trip so a spare makes decent sense. As you saw, I did mine again just because the engine was out, and 150 bucks was not a lot in context of how much I was already spending. However if the engine was not out, then that pump would have stayed in there until it started leaking.
Thanks Erica. Mine seems fine now, but I hope when it decides to go I can hobble along for a while if I’m on a tour. If not, I’ll be relying on SNG or XKs to send one post haste.
I had a new Series II pump I carried around on my first tour until I checked and it wouldn’t work on my Series I. I carry an alternator, a fuel pump and a bunch of other items plus tools. Guess I need to get a water pump.
use the image in a previous post and identify bolts and locations
tack the gasket in place to avoid misalignment
use a jockey pulley to keep the proper belt tension and avoid stressing the bearings
double check rad hose fitting especially the bottom one
if you are using the newly manufactured pump from XKs, install the pump pulley after you mount the pump otherwise it would fit through the picture frame
