First off, thanks for establishing and keeping up such a great forum. I went through the past 3 years of threads before I bought my Hummer and the information posted was of tremendous value. I bought a 2007 H2 Arctic Blue with every option and 95K miles. The owner left it stock except for the radio which is a Pioneer that has Apple CarPlay. I plan on keeping the truck for 4 years and 40K miles. From my reading it appears to me that the first 2 repairs should be:

1) Replace the rusted brake lines since a failure could be catastrophic
2) Replace the radiator with one that isn't intertwined to the transmission (not sure if I got that one right, hopefully the mechanic will know)

The other items I can run to failure like the shocks & air suspension

Maintenance items should be:
Change all fluids
Reseal all lights
Underbody rust prevention

What did I miss?? Again, thanks for all the collective wisdom on this board. I'll contribute where I can.

 

if the brake lines are corroded then inspect the top of the fuel pump they tend to rot out about the same time.

 

2007 Glacier Blue Metallic Limited Edition.

 

Great idea, thanks. The break line replacement is way beyond my skill set so I’ll ask the shop to look at the fuel pump as well

 

Congrats! That is a very clean looking H2. Show some pictures of the undercarriage frame rails and brake lines let see what kind of condition it is under there. what you need is the aftermarket transmission cooler and for it to be installed to bypass the radiator. all together.

 

very clean, someone took care of it

thanks for sharing

Love that color, have your truck inspected, if the lines are not rusty, then maybe they don't need replaced, the lines on my 2006 are fine. I went with a new radiator from the GM dealer as preventative maintenance, did new hoses and fluids at the same time.

 

If the undercarriage and existing brake lines are not looking bad there is no need to replace the brake lines. Mine is a 2003 and the brake lines are perfectly fine. Just depends on where it came from and if it was cared for. The radiator - while it is possible for one to develop a leak between the trans cooler section and the main radiator (can also happen between the engine oil cooler section), that realistically is not a super common issue. The reason you hear about it is simple, the other 99% who have not experienced that have no reason to complain about it happening. The few who it did happen to, rightfully so, tend to be very vocal about how upset they are that it happened. Even then, most who it did happen to, still replace the radiator with the stock type. Otherwise you have to then look at dealing with the transmission cooler lined and the engine oil cooler lines which both attach to the radiator. Again, it "could" happen but it is not as frequent of a problem as you might think by reading online. There are literally millions of full size GM trucks and SUV's on the road, as well as millions of other vehicles on the roads that use the exact same type of radiator with integrated transmission (and often engine oil as well) coolers. It is not an inevitable thing and likely will not happen, but it certainly could. If you feel that due to the age it would be good to go ahead and replace the radiator, then by all means as a good flush of the cooling system and replacement radiator will certainly not hurt anything.

Yours does have an extra button someone added which is on the dash just above the headlight switch. Air suspension is generally not troublesome and short of a major failure in the compressor shelf itself is usually not expensive to replace a failed air spring. It is very nice to have if you tow anything since the rear is self levelling. Also with H2's climbing in value and collectability, originality becomes important. I'd personally discourage ripping the air suspension out and converting it to coil springs.

The real common issues, the most pervasive on an H2 being water leaks, yes that is one to look into asap. On that it is not a matter of if, it is a matter of when and where from. That being said, the prior owner may have already taken care of things. If after heavy rain you have no signs of water in the floorboards then just enjoy it. Preventative maintenance is of course a good thing though such as making sure the sunroof drains are clear. Very nice looking H2 and congrats!

 

Looks to be a very nice truck, great colour and it's great to see one in good condition.

Could that extra button be a water heater? My friends truck has a stock water heater, so I assume there must be a switch somewhere.

Brake lines very important and I speak from experience and a few near misses, It would be worth getting them inspected, there are 8 galvanized-steel solid lines, and 6 flexible lines, one particular bad spot is where the mount just above the rear diff, it tends to be the one's out-of-sight.

As MixManSC say's if the lines look OK then no problem, it's easy to spot corroded/rusted lines.

Does it fit in your garage?

 

Will do. Seems some on forum have had a good experience with a “rust converter”. I’ll try that and see what happens.
