Welcome to the insanity. Its nice to have another 97.5 H1 owner on the board.

ok seriosuly someone explain why for 1997 its the only time youll ever hear 1997.5, like why dont you hear, 2000.5 or 1996.5 etc.?

Thanks for the warm reception guys. I guess the owners of the 1997.5 Hummers want to make it known that they have the updated HVAC systems in their H1s as factory equipment.

I've attached a photo of my old ride ( 1970 hemi Cuda ), and my new ride ( the H1 ). I think the Hummer will be easier on fuel )

that is a beastly brushguard on the h1, you might want to raise that front license plate bracket so you dont loose the license plate when yuour out offroading

Nice looking rig. Your gonna love those cepek rims, are they 16.5 or 17's? The tires gotta go, you need something a bit more meaty. Looks like it was kept outside from the looks of the brush guard and winch. Make sure to measure those front springs. The factory winch is a heavy mofo, which will wear those springs out pretty fast. When you throw that 150 pound brushguard on top of it, that only compounds your spring problems.

It was actually kept inside for the past 8 years, which I think was also the last time it was washed. It only has 33K miles on it, and the engine was replaced under warranty 9K miles ago.

The rims are 16.5 " and I plan to put on a set of Parnelli Jones Dirt Grips as soon as it arrives. Is it a smart move to keep the 16.5 factory rims, or should I replace them with 17" and get the new tires in 17" ? Any suggestions for tires ( it will be on-road most of the time ) ?

Thanks for the tip on the front spring height. Please send me more tips, as I am completely new to the Hummer scene.

I am just starting to gather some new parts ( ball joints, halfshafts, brake pads/dics, etc ) just to have on hand if I ever need them.

Yeah, the 97.5 have some costly upgrades that make the rig much better.

[3Hummer]

What happened to the engine that it was replaced at 9,000 miles under warranty? And has it even been driven in eight years, that cant be good for the car either they need some exercise every now and then

I'm not positive, but I think it was because of the bad #8 cylinder problem on some blocks. It was done at a Hummer dealer shortly before the last owner purchased it. He has a copy of the work order, so when I get to see it I'll know for sure. I sure hope those replacement blocks were better than the originals. Does anybody have an answer to that ?

Great rides bro !! %Welcome to the site !

[ssgharkness020147]

Yes. They were better. As to what extent depends on the year. Some say that the No 8. was a problem til 2001, for the record most people saying that are trying to sell a truck. My truck has a 99/00 block in it, and over 70K on it, with no problems (JINX). IMO, You'll be fine, just dont go nut with power add ons. The 6.5 in stock form was not ment to be making 350 Hp, with 600 lb/tq. The main issue you could face with a newer block is headgaskets, which do tend to fail. I had mine fixed (both) for under 2K when one went.

Thanks for the positive news. I'm not planning to install a lot of engine mods, but I do plan to replace the stock exhaust system with a stainless steel system that removes the catalytic converter and maybe the muffler.

I also plan to install a rear cylinder head cooling kit. Do you guys have any of these installed ?
