All this talk about water pump failures makes me nervous.
You see, I installed a "rebuilt" pump from 928 International in 2003 and haven't touched it since - put on approx. 42K kilometers/26K miles since then. Not sure what to do ?
CHANGE IT IMMEDIATELY!!!
I put one in my car, ran it for 4 years, thought I was good as no cooling problems. When it was time for new timing belt, I pulled the pump and found it ground into the block significantly. I had to do the PC-7 epoxy fix, the gap was almost 1/16" that it cut into the block. I didn't have any overheating, noise or anything that would indicate the impeller moved on shaft and was grinding into the block..

Installed a Guardian pump, and all is well.
I was getting nervous, now you make me feel paranoid. You call that help ;-)
Kidding aside, that is a scary looking stuff. Why do you guys drive cars that "eat" water pumps ? (or is it a case of crappy water pumps) It's been 14 years but I'd swear my old water pump felt as solid as the new one I put in. I questioned my wisdom of changing it. I'll double-check the records I got with the car but I think it was the original pump with approx. 80K miles on it.
Can't believe you didn't hear the impeller grinding into the block.

It is a silent death. Believe it.

Monitor the location of the bearing cartridge.
You will need a small inspection mirror and a good light source.
- Pull the driver's side timing belt cover.
- Run the inspection mirror underneath the pulley and find the weep hole in the raised structure of the casting that supports the pulley.
- If the trailing lip of the pulley occludes any part of the weep hole, your impeller is migrating.
- If not, then it is highly likely that it isn't.
If you find other threads about migration, I've posted pictures. I'll try to find them, when I can, but that'll be not real soon. Post back if you can't find them.
I practice what I preach: my '91 has a rebuilt pump that was installed in the 2006-2009 timeframe when the pumps were falling like rain. It's one of two out of a dozen or so that I installed in that period that hasn't already failed.

Dave, thanks for the constructive post. Seems to me like the most rational approach. I may not get to it for a while, getting ready for a hernia surgery, but after recovery I will take a look at it.
I just have a problem with blindly pulling out a pump that has worked for 14 years and replace it with current vintage of pumps that are failing at a rate that is just unacceptable to me.
Adam from Ontario just reported a Laso pump failing after only 3 yr.s/20K kilometers. Another fellow mentioned 3 pumps in 8 yr.s, ridicules. The Guardian pump may be the solution, waiting to see/understand the cause of Bertrand's coupler failure.
Happy End of Year Stuff to everyone from Camp 928! Time to make your resolutions about your cars, e.g., checking your water pump and attending the 2018 edition of Camp 928, June 15-17.
I'll start getting things organized in the next weeks, with help from those who know where I need help!
The Camp 928 Clubhouse is closed up and nearly done on the inside. Lifts should be arriving next week. Kinda chilly for putting up the siding, -10F this morning.
A small varmint has already found a home.
Parking lot was lost to new garage, but plenty of more space elsewhere.
How about a shot with the overhead lights on. Interesting that you chose something other than fluorescent or faux-fluorescent LED. Is the Smart car what you use to get around your compound May to November?
Looking snowy outside. Cozy on the inside...will it be climate controlled? Working in a warm garage during winter is one of my favorite pastimes. Really looks great...the peak for tall lifts is nice!
I gave lighting much thought. Some of the guys at Garage Journal like retina-burning levels of lumens/square foot. I figured out what I had in my current workroom, and went for something in-between, 31 lumens per square foot. My old eyes have trouble with shadowing, so I considered broad lights, like standard four-footers (but LED) and even stringing 200 feet of 24V LED strips. Putting up 16 or 24 big fixtures on a 10-14 foot ceiling gave me pause, so I settled on this easier solution: 8 "Big Bulbs" that spread light all around, bouncing off 6 gallons of ultra-white paint everywhere above 8 feet. It's working well for carpentry tasks.
The plan is to install - myself - a Mitsubishi mini-split AC/heat pump unit, the new sort that puts out good heat even when it's very cold outside, even the -16F we had last night. If I can work on a 928's AC, I should be good, right?
Almost goofed and put the front bulb fixtures above where the garage doors go.
Curt, looking really good!! cant wait for Camp 928 2018! -16 degrees...Brrrr we were down to only -2 degrees in Massachusetts..stay warm and happy New Years !
Add a light-colored finish to the floor to benefit from the reflected light.
Interesting choice of lighting method, by the way. As I age I find I like more and more light in the work areas. I started out with way-overkill florescent and LED lighting, and put in dimmers. The biggest challenge is still getting adequate light for tasks under a car while it's on the lift. Ends up being something that's movable, magnet base, etc.
Do you have a separate thread for your garage/workshop project? We can move the garage-related posts here to that one if you do.
When we bought our house 5+ years ago, light in the garage was dim like a horror movie basement. Plenty of sockets but 60w bulbs were pathetic. I replaced them all with 3,000 lumen curly florescent bulbs and that's worked fine. When the first two went out earlier this year, I replace them with 10,000 lumen LED "corn cob" bulbs. Holy Hell.....these things are awesome!!! I figure over time do half / half will give me just the right amount of light.
I've been considering these for a while now, but finally decided to try them once Menards started to stock them figuring it would be easier to return if I didn't like them or they burn out in an unreasonable amount of time or something.
Only downside is, not dimmable - I'm hoping new version down the road are.
Curt - Your timing is perfect. I've been considering the Mitsubishi and LG mini-split systems for my garage and for a remodel of sunroom into 4-season space. They look fairly simple to install. Hmmm...will be fun talking to you about this at Camp928.
