Hummer has been in the garage for a while now.

Well the Hummer had been stored in the warehouse for about 2 1/2 years now and only just got back out on the road again. Since then, I got a new house, so my attention has not been on the Hummer at all. Finally about 3 weeks ago, I worked on mounting the new tires since my right rear tire was always leaking, and showed signs of dry rot. But I still had a good amount of tread on the tires and they are around 8 years old now, so it was time for a change.

Also had a hard time starting the Hummer while it was being stored and I knew it was the glow plugs that was the cause. Got new plugs and installed them and the Hummer started right up unlike it was before. All 8 glow plugs where bad, electrically open. I started the Hummer up about once a month and drove it around the block, and back.

Got the inspection and tags updated and it feels good to be driving the Hummer again after about 2 1/2 years.

Oh yeah, I also had to have the water pump changed out due when the belts broke, it also broke the seal on the water pump Oct 11 - 2009. And got new shocked installed too. I forgot when I did all that, I think it was in mid 2009.

April 2009 I got a motorbike, so less time thinking about the Hummer.

Tires

Got some new tires from Community Tire Retreading this summer and need to replace my old tires that I got from them many years ago.

Bents & the Water Pump Replacement

Been a while, but here I am once again. Last thing was that the belts broke and I said no biggie, well it became more then just the belts to replace. When the belts broke, it also bent the shaft on the water pump and that also had to be replaced. So I left it for a while do to other things going on in left around me. Finally got it fixed over a year later. Sent to to A&L Automotive on Grant road and I was back in service once again.

Belts! & Water Pump

Well while sitting in a parking lot enjoying my new AC system that has my Hummer down to 67F in side and windows all fogging up on the outside, a belt broke. It was the alternator belts. No biggie, drive it back to the warehouse. Next morning I got new belts.

Two belts broke, both for the alternator. Found a second belt had jumps to the wrong pulley and was also twisted. Removed all the belts. Then found that the water pump is now very wobbly. I think one of the broken belts got under the other belts and caused the pump to break. So, I will have a shop fix it, I don't feel like messing with it right now, just too hot out!

You Know the A/C works when ......

Yes! Finally the A/C is in service and you know it is working when all the windows (except one) are all fogged up on the out side. Only the armored window was not fogged up. The A/C blows cold air even on a hot 90F day like to day while sitting idle. And on move it chills the vent air down to 43F before the compressor will shut off. It normally blowing between 43F and 48F.

Some time back in June , I got a new A/C compressor. Then finally in mid July I got it mounted. Then finally the first of month, August I took it to the A/C shop to have the connectors fitted and connected. Ran in to a problem, 2 problems, 1) I did not have the connectors for filling the system, and 2) the new inside A/C core had a hole in it. So Monday it was not completed due to lack of the fittings for filling. Tuesday it was not completed because of a hole in the coils we found when filling the system. Called up RedDot and they sent a new coil over night and so Wednesday it was finally completed.

I want to take it back because the connectors and hose are not in the right place and as a result, the side cover does not fit right and the hose is on a sharp edge under the hood. And I also have no low pressure switch in the system.

But other then a few minor issues, the system works great. The system sits between the rear sits, but the air flow you can feel up front with out any problems.

Setting the temperature is limited to 3 settings, you set the fan to low, medium, or high and once the coils get so cold, the compressor will shut off. So, so far I know the high speed setting is 67F before the A/C compressor shuts off with it being 90F outside. Also with the new fan on the outside, you can feel the air being sucked in under the hood scoop.

Now I have to make a few other changes in the wiring, since this system has two blower motors, it pulls more current then the older unit which had a single blower motor. Then I need to make a new cover for it to dress it up some. All in time.

A/C Shop: $450 for installing the fittings and charging the system.

Fuel Tank Sending Unit

Well last weekends work was not a waste, last night I checked out the resistance and all looked good. I got about 192 ohms from the sending unit and once I plugged the connections back located near the tank under the truck, I checked the gauges and it was reading 3/4 of a tank. Drove around, went to the gas station and filled up, and now I can see, I have a real full tank of fuel. I ran out once, and believe me, I don't want to do that again, cause it took me a while to get it primed and I ended up using a half can of WD40 as my primer to get it started.

Discovery info: I figured it out, Since a empty gauge means an open or high resistance, the full gauge must mean very little resistance. And I tested the old unit and it was still working. I have a feeling that there was a short on the last cable clamp next to the sending unit since it was crushed and was corrected before re-installing the tank.

Now this weekend I just got to get the wiring completed and then maybe next week If I have time, I will take it to the A/C shop to get the hose fittings installed and system charged, oh, one more thing, I need to change out the compressor, don't want to take a chance that it too was bad.

Hoses Installed!

Well this weekend I finally got the hoses all installed and just about ready to go. I figured I would have to drop the fuel tank in order to get the hoses where I wanted them. But I found out that there was no room under the tank, so I really did not have to remove the fuel tank after all. But since I had the tank down, I replaced the fuel level sending unit.


I bought 25 feet of high and low pressure A/C hose, and only 26 of heater hose that is only equal to 13 feet per run. And my new A/C unit is in the rear between the rear passenger seats. I figured that I was only going 9 feet, so 4 extra feet to cover it, end to end. Well I was about a foot short on each run for the heater hoses. So, no big deal, I can add on that those lines with out a big issue. In the end, after all the looking and figuring out where the best place for the hoses to go and to enter the cab at, I ended up going in on the right side, behind the right rear seat. So the lines come up the same side and the fuel fill line is also.

Now I need to go and get a new A/C compressor since I have a feeling that this one may not be all that good, I think it has poor pressure when I am rotating it. And I then also need to make the electrical connection, and that will be next weekends project. Then it should be off to the A/C shop to get the hose fitting put on and freon put in the system.

On the fuel sending unit, well after replacing it, at first it looked good, I saw 3/4 of a tank of fuel, then the next time I looked it was reading EMPTY. So now I have a second electrical item to check out also.
