Hummer H1 Fuel Economy
The vehicular universe does that statement apply more than when in reference to the Hummer H1 differential. You’re chasing a group of rebel forces through a large city, possibly Los Angeles. It is possible on the set of a Michael Bay film. the crazed terrorists make a turn and they’re driving on the beach! They’ve just hit an umbrella! A cooler! A towel! Beach volleyball players are fleeing in all directions! At this moment, you must stop for a minute or two to let the air out of your tires using a switch on your dashboard.
Hummer H1 roll cage resume the pursuit. You’re right behind! Closing in! Neck and neck! When in an instant… they’re back on the pavement But wait! You stop and press the dashboard switch once again. After a few more minutes, your tires are fully aired up! You’re back in the pursuit! You drive on the sidewalk! You hit a mailbox! There are explosions! A pickup truck smashes into a telephone pole! A cow is split in two!
Of course, that was never a problem for the original commissioner of this art car, Dennis Rodman. No, his problem was airport metal detectors. Rodman, the former basketball player, wrestler, actor, and North Korea visitor once actually drove this. Seriously, it’s got 23,000 miles on it and he added some of those, and in broad daylight too if past pictures are to be believed.
But eventually you get the terrorist, who must’ve been driving a riding lawnmower in order to be caught by a Hummer H1 engine conversion, and the plutonium is recovered, and America is safe, at least until the sequel. And it was all because of your tires, which can add or remove air at the push of a button.
A normal running engine has a 195-degree thermostat. It should run with the temperature gauge a little to the left of 200 once it’s warmed up. Don’t be alarmed if your gauge isn’t reading exactly. The gauges used in the Hummer H1 hood scoop are not that accurate. With a cracked engine the temp will fluctuate up and down and you will be losing coolant. Check the CDR valve which is the big round gold unit on top of the engine. Pull it out and see if there is a milky white sludge in it. This will be the sign of an oil and antifreeze mixture. When the vehicle is first started you see the white smoke and then it clears because the coolant leaked in at the engines last cool down.
Hummer H1 grill guard also get a roof-mounted spotlight, I guess so you can find real boobs at night, and some big speakers inside because the H1’s cabin was too roomy and obviously needed some accouterments to make it feel cozier and inviting.
Hummer H1 dealer makes 8740 chrome-molly steel cylinder head studs that fit all 6.2/6.5 GM diesel. These are 190,000 psi tensile strength fasteners that provide the superior clamping force for the critical head gasket seal on these engines. They cost more than replacement TTY bolts. Anyone who has ever had one of these engines apart from head gasket problems ought to spend the money for the superior ARP product. Because some of the head bolt threads protrude into the water jacket, use a thread sealant on the threads. I found the best sealant to be three turns of Teflon tape, used on the lower threads only.
