1994 HMCS Project

Foam insulation seems to be going in well. It might make squeaks when driving, but this has YTD. It is easy to cut, very flexible, and expands when you let it go so it fills up the space, and holds itself in. Seems like it will dampen the sound significantly if I can put enough in.

Time to go looking for A/V equipment!

So this one doesnt have the upgraded heater unit right??? I dont know much about H1's but was wondering can these be fixed and if not whats the cost of an upgraded unit?

Your doing all this work on it, and i cant even figure out how to put on my rear lamp brush guards, then again handy work defintly does not run in the family.

[3Hummer]

after all this work you could probably sell it for more than you bought it. Also which engine does it cuase didnt they offer two different engine options.

[BlueHUMMERH2]

NHG,
This is the original heater, correct. You can buy the new one from AM General for something like $4,000. Or you can get a 1992/1993 unit for about $400-$700. Or, like I want to do, carefully take it out, disassemble it, and replace the components, and then reinstall it. I think I want to build a whole new unit actually and put it in.

3Hummer,
This is the 6.5L engine, the larger of the two available. The truck has most other options also, such as CTIS, Upgraded sound (which still sucks), 2-piece rims, etc.

Well will most likely be a lot less expensive than 4g's. That should be one hell of a project. At least summer is approaching (I think) so heater wont be needed much

I have begun to install the acoustic dampening material. The foam-like pipe insulation has gone in very easily so far, and fills the spaces in the doors/pillars nicely.

Here is the foam in the passengers side, up around the roof. Looks sort of like what was in there!


This is in the b-pillar:


For the smaller areas, instead of HUSHMat or something else thin and expensive, I opted for:


I will be amazed if it works, but if I think the foam works, I can't see why this wouldn't. I found it at walmart, and it's about $0.50/SQ Foot! But if anyone ever tears this truck apart, they're going to be in for a colorful surprise!

excuse my ignorance, but what does HMCS mean?

thanks!

HMCS is the wagon H1. HMC4 is the four man opentop. The VLCO had the zip out windows and the soft top. I don't know the rest off hand, but they were short-hand within AM General for the different models.

do you know what the initials actually stand for?

thanks again!

There are all the designations, but no explanations. I will have to ask around next time I'm at an AM General event.
