H1 in various seasons
 

I was wondering for those who have an H1 and live in areas where the climate changes how they run. I'm in Canada so it get hot here about 2-3 months. Hot and humid - not dry. Then our winters can get pretty cold but in my area it's not that bad.

I live in the midwest where it gets very cold in the winter and very humid in the summer. I have not had any problems. On very cold days, just use the block heater.

Dont have one so cant get a full opinion on it. But I live in florida, and its very hot and humid all year round and theres a fair share of H1's down here, so i cant imagine they run bad here if quite a few people have em. As for cold, only thing i would see a problem, is doesnt diesel become like a gel i the cold or someting like that?!

Re: H1 in various seasons
 

Good to hear. Block heater will have to do. We have a 2 car garage and the H3 fits on one side but the H1 will never fit on the other. Looks like I'll be parking it on the driveway all year round.

I live in mid Ohio, never had a problem due to being to hot or cold, most stations run with winter diesel anyway after November, and then switch back around March

Good to hear. Deposit is in for the H1 ow I just have to wait to have it imported to Canada!.

Nice, what color did you get??? What year did you get??? and is it the open back or the suv

I live in Northern Idaho, about 80 miles south of the Canadian border. I use my H1 to pull my snowmobiles. I was in McCall, Idaho in January with beautiful sunny days, but the mercury was at -16F. My rig started every day without being plugged in. I would recomend plugging in however. As for you H1 owners in the south, all of the deisel pumps begin running a diesel blend from the pumps with 'anti-gel' beginning in Ocotber, November. I still put additive in mine if the temps look like they will drop below zero. My Dmax Chevy gel'd up on me when I was travelling down the interstate due to below zero temps compounded by wind chill.

One other point. A heated windshield is a must. My 2000 H1's defrost has a hard time keeping up in extreme cold. I turn on the heated windshield and crank my heater to keep me warm. I have a 92 H1 w/o a heated windshield, and it sucks to drive in the winter. I have to choose to either keep the windshield clear with the defrost or keep me warm with the heat.

Good to hear about the different climates. I'm getting 95 wagon, with tinted windows and it the dark metallic green they had that year. I hope it doesn't take too long to get here!! However it would be prefect if I sold my car before it gets here!

Re: H1 in various seasons
 

I don't want to contradict what everyone is saying but my '94 is a real pain to start below ~40 degrees. I've been tweaking a few things and its getting better but I'm still hesitant to go anywhere where there isn't a place to plug in when its below freezing. I'm guessing its something that can be fixed. I've never had a diesel this cranky before.

Re: H1 in various seasons
 

I guess it's good we have a H3 just in case! I just bought and dowloaded the parts list and service manual. I also printed all 1600+ pages of them too!!! It's nice to have a network printer in my office!!:jump: :jump:

Once I get the H1 I'll go over it and may have another guy who works on them do the same for me. Heck maybe I can assist him in some stuff to learn more about it.

Cold weather starting trick of the trade--Cycle your glow plugs. Turn your key on and when your 'wait' light goes out, turn the key off and then back on until the 'wait' light goes out, then start. You can cycle your plugs 3 or 4 times if necessary and it will not hurt anything. I learned this from my dad, a 20 year long haul truck driver. If this doesn't work, you may have a glow plug issue or just a plain-old cold blooded Hummer.:D

Re: H1 in various seasons
 

Good info!! I'll need it when it gets cold up here! ANy problems in the heat? My H1 is coming from Arkansas and I'm not sure what the weathers like there during the seasons. It's been in the same state since 95!

Re: H1 in various seasons
 

I've tried cycling my plugs a few times before and never had much luck. The second/third times they only stay on for a fraction of a second and starting is no different. All plugs and the controller are new. Compression is good. Any other hints?

Re: H1 in various seasons
 

Hot and humid in the summer.

Just curious, is there a solar powered block heater? Not sure if it'd be practicle, but the thought just hit me so I'm asking.

Re: H1 in various seasons
 

Not sure about a solar block heater but at least my small solar panel I bought a few years ago might come in handy now. :excited:

Re: H1 in various seasons
 

With A 94 MY hummer, I believe they were all non turbo with A mechanical pump? For cold starting you can also put the throttle pedal to the floor and it will help in starting. Make sure all glow plugs are good, should have A 15A draw on each plug. Test 4 at A time and go from there, each bank should have appox 60A draw. On A mechanical pump you also need to make sure the cold advance works, consult A service manual for that one as I have not even seen one for A few years.

Re: H1 in various seasons
 

Something that you might want to consider is installing an engine heater like these ones from Webasto. They use diesel to keep the engine warm, and come with timers so you can set them to start a couple hours before you need to go somewhere, or use it on demand, or all the time. I found out about them through my dad when he bought them for his semis. I'm in Canada too and would seriously consider them on a diesel.

Re: H1 in various seasons
 

I'll look at a few different ones. If I can fit into the garage I will but our H3 uses the space in the winter. The other side fit my PT Cruiser but hopefully that's sold soon. All the tools and equipment I have will only fit one of the Hummers in there now. What makes it hard is that it's a 2 door garage and not a single double door.

Selwa,

When I had my h1 a few years back it fit in a standard size garage all I had to do was fold in the mirrors on each side.
