#18112 of 18277 Water pump replacement job - 2002 TB by johntr Jan 28, 2008 (2:07 pm)
I started hearing a rattling type noise from the engine at idle speed. I figure it is most likely the water pump bearings. I don't have any leaks, but I want to replace it as soon as possible. My question to those that may have taken the task on them self... Is this something that I could do rather than taking it to the garage. I have ~128K miles on it. It's a 2002 Trailblazer, I-6 engine. If it is something I can do, what should I expect to run into? (remove fan, fan clutch, serpentine belt, ect...?) I am fairly mechanical, I used to do my own repairs from valve cover gasket replacement, manifold gaskets, engine starter replacement. But I have never worked on anything newer than 1990.   Just trying to get some ideas as to the value of the job.   Thanks John Replies to this message: ugltrk (Jan 29, 2008 1:29 pm) johntr (Feb 02, 2008 1:20 pm) johntr (Feb 17, 2008 11:01 am)

Replying to: johntr (Jan 28, 2008 2:07 pm) John, I would check the idler/tension pulley bearing before I went too far.I've had them rattle, and squeal like a water pump.   gmfan4,..I would suspect the radio..   Just a shadetree guess...Bill Replies to this message: johntr (Feb 02, 2008 1:20 pm) johntr (Feb 17, 2008 11:01 am)

Replying to: ugltrk (Jan 29, 2008 1:29 pm) Thanks for the advice. I actually got to look at it today. The fan is loose where it is bolted to the wheel assembly. Is that the fan clutch assembly or just a bearing assembly? I can wiggle the fan by the fan blades.   I will be dropping it off tomorrow at the dealer.   John Replies to this message: johntr (Feb 17, 2008 11:01 am)

Unless you checked to see if the bolts are loose,prob the fan clutch assembly.   Bill

Replying to: johntr (Feb 02, 2008 1:20 pm) I didn't have time to replace it, so I took it to the dealer - It was the water pump. All is well again...   Thank you all for the feedback.
#18117 of 18277 Wet left foot? by seiford Feb 18, 2008 (10:18 am)
I've been noticing that the top of my left shoe is wet after driving my 2003 Envoy. It looks like dirty water (from melted road salt/snow crud).   Anyone else ever experience this? Where is the leak coming from?   Thanks.
#18118 of 18277 02 TB LTZ 4X4 switch by bobed2121 Feb 19, 2008 (9:09 am)
Seems that since I had the Transmission rebuilt my 4x4 switch is jumping back and forth from 2wd to Awd as I drive. I can feel the slight clunk as it transfers back and forth into each drive mode. I had the switch replaced once probably around 40,000 miles or so (120,000 now). Anyone know what causes this and what needs to be replaced? As I recall it is something in the transfer case that causes this to happen?
#18119 of 18277 '02 Red Trailblazer - RIP by wharthog69 Feb 19, 2008 (8:10 pm)
sigh. My very reliable, very low maintenance '02 Trailblazer with 175,000 miles died on the way home from a work trip last week. It doggedly traveled 5 miles and up a steep mountain with no oil pressure to a service station near Shady Springs, WV to make sure I got somewhere safe and warm. The engine seized just as I threw it into neutral pulling onto the lot. It was 20 degrees, 9:00 at night, with the wind blowing hard. I'm gonna miss it.   I never realized how emotionally attached I was to the thought of snapping it's 200,000 mile pictures and showing them to everyone. I guess it just won't happen now.   Anybody doing anything interesting with broken Trailblazers these days? Engine swaps?

Replying to: wharthog69 (Feb 19, 2008 8:10 pm) I think with that many miles I would just let it go. We just turned 60K on our 02, hope we get another 115K out of it! Replies to this message: wharthog69 (Feb 20, 2008 4:45 pm) ross1962 (Feb 22, 2008 2:48 pm) bobed2121 (Mar 06, 2008 8:50 am)

Replying to: wharthog69 (Feb 19, 2008 8:10 pm) Well let's see. Hows the suspension? Does all the electronics work still? Brakes in good order? No body damage? If you have minimal problems then just get a couple estimates and replace and or rebuild the engine. Or you can go down to your local dealer and start making those strokes on another depreciating asset. Yeah it will smell all nice and the paint will shine but it will be just another used car in a couple years. I will never I REPEAT never buy another brand new car as long as I live. Let some other fool pay full price then swoop in there after a couple years and take it for what it's worth. Has anyone ever bought a used car based on Kelly Blue Book to have it depreciate by 25% only after 3 months? Well that's what happens on brand new vehicles. The big three will be just like the American TV manufactures. Just a name that we once new. Pay a couple grand for a new engine drive it until 2012 then consider getting another car.   Just my $0.02 Replies to this message: wharthog69 (Feb 20, 2008 4:41 pm) ross1962 (Feb 22, 2008 7:45 pm)
