    Anyone notice how the H2 (Concept) looks really H3-like?

    Gas engine.... 6-spd tranny. It looks like the H3 might have looked if they didn't discontinue it. I wonder how large it'll be? Is it coming out or just a concept? If it's in the current H3-ish size range, smaller than a H2, larger than a Bronco, might be something to think about. If it's...

    Changed oil and found this!...

    That's the L side of the AC Delco filter which collapsed inward. Seems to run fine. Been on there for a yr. Not like the bearings are spectacular anyway. Life goes on. What do they say??? "You can't kill an Atlas 3.7L!" ....they die on their own LOL!😂

    Backflushing the Power Steering Reservoir (pics)

    [broken pump] Ouch! What fluid were you using? Not that it really matters. I saw that pump on RockAuto with the reservoir. Round body....Looks like a Colorado or some other pump to me. I've looked at both pumps, pretty sure the Colorado reservoir won't fit on. Has anyone tried it? Worst case...

    Backflushing the Power Steering Reservoir (pics)

    Been going through a low Power Steering issue lately. Decided to back-flush the PS unit before I buy a new pump. Thought I'd post a picture how I did the flush for others who might need to do the same. A plugged internal filter is not uncommon cause for PS issues. First remove the pump and...

    H3T Hummer H3T fuel pump discontinued?

    Does your gauge still work properly? OK, I havent looked to see if it's available, hopefully you'll find one. But for what it's worth, if you Can't find a new fuel pump, don't fret. I'm the kind of guy who likes to buy OEMp parts...... but I have to admit I've had a few vehicles I've owned...

    H3 Sunroof not closing

    Start by looking at the obvious stuff up front by the motor (up front..easy to get to). Remove motor, look at gear. See if you can slide it back. Be cognisant of the cables/belt (can't remember which)... so you keep them straight. Like I say, it literally takes like 5 min to drop the headliner...

    H3 alpha power steering pump

    Here's the link of (Colorado) pump differences. Maybe there are multiple Colorado differences too...IDK. https://hummer4x4offroad.com/forum/threads/h3-i5-power-steering-pump-comparison.16357/

    H3 Alpha oil leak. At our witts end

    Some oil leaks are harder to pinpoint than a person would think. Esp when everything's oily. I've been there on various engines over the yrs. Long road but glad you got it fixed!

    H3 Sunroof not closing

    Start by checking the fuse if you haven't already. Pull off the lace around the sunroof and the headliner should drop down a bit to see the motor and mechanism a little better. See if anything is loos as far as the retracting mechanism goes. Backprobe the motor to check for power. You can...

    H3 Sunroof not closing

    There's a plastic gear that commonly breaks, or the teeth break off. It's available off ebay for like $10-$15. Not sure that's your problem, but dig into it. Might be what you need. I bought one just to have as a spare...just in case...

    Flickering lights then dead BCM issue

    That was back in the 80's a guy could swap eproms. lol Trace back your brake wiring. Look in your bulb connectors just to be sure nothing is shorted. Could be a shorted brake switch or even turn signal switch, or flashers. It's going to require some meter work. How is the battery to body (and...

    Need help with 'Reduced Power' msg when I give throttle a bit too quickly

    As far as the other errors go, has your tk ever been in an accident? There's a sensor that monitors intertia and stability under the driver's seat. Those have been known to go flaky for some forum members in the past. You might do a general google search on those errors and see what comes up...

    Need help with 'Reduced Power' msg when I give throttle a bit too quickly

    You might do a compression test too. It's somewhat common on these engines the center cylinders burn valves. Esp #3. Mine's had low compression on #3 for a few tens of thousands of miles. The ECM keeps track of misfires and when they get high enough over a given period of time (3 seconds? 4...

    Hummer H3 - Replacement Rear Frame Shackle Mount

    Wow..you're right. Those are terrible. You'll probably have more metal work to do once you get the old ones cut off. I'm sure you can modify new or fab-up shackles once you get into it. Love to see the finished product.

    Well...Lol! As luck would have it I need the ever allusive 434 (02207B) door check again!!

    Just the spring, or is there more going on I can't see in the pic? Must be bad luck. Did GM use them in the Colorado's or another vehicle?

    Leaky Sunroof

    Yep! Good call. Definitely another possible source of leaks (and headaches if the bolts rust in).

    Leaky Sunroof

    I've been fighting leaks and wet carpets since I bought my rig years ago! :rolleyes: I've had the interior/carpets out a couple times. New sun roof gasket. Tried a number of things that never seemed to work. We had a lot of rain this summer, esp in July. This fall I had an inch of water standing...

    Oil usage observations

    I don't remember (and too lazy to re-read all the posts) ...did you ever do a compression test?

    Oil usage observations

    Good to hear the updates. Walmart sells T6 around here, as do the Farm n Barn stores. Here's an idea...crazy as it seems. If dollars matter, do some commuting calculations: a smaller electric car would cost you very little to commute up over the mountains. You gain back (regen downhill) most of...
