post to start cranking it over as soon as the glow plug light goes off . I weld a 6.2 Detroit once cuz one person cranked engine over to late and the 6.2 Detroit outer starter bolt broken the bell housing and I had to weld the block and drill it and Thread tap the block to bolt the starter back on lol 6.2 Detroit are knowing for that one day it will happen
Use a block heater, a lot easier on the starter, the engine, the glow plugs etc. As I recall, that was a Chevy diesel. Detroit and Chevy both owned by GM but not the same. I had a 6.2 naturally aspirated in a 1 ton in Alaska. Had to start it once in Chena Hot Springs at -50 F, ran the block heater and battery blankets for two days before, wrapped an electric blanket around the engine, it was still hard to start but the old rig finally fired up. It's a good engine.
Gotta run the glow plugs longer. I switched my '82 to manual and run them for 10 seconds the first time and she fires right up then once or twice intermittently once running to help warm things up. Don't be scared to get um hot and no need to wait once cycled.
below 35 you are supposed to give it throttle to help it start it even says so in the back of the visor i couldn't give it throttle because i didn't get in the truck
@@justinthor If you hold it too long it could burn out the glow plugs. I had a 79 Oldsmobile Tornado with the 350 Diesel engine. It had an automatic timer for the glow plugs, but it didn't work so I wired it to a push button and would time it with my watch. Worked good. I replaced 2 glow plugs I think they were cheap and easy to replace.
It is not if you spent more than 10 seconds researching you'd know that the 6.2 was built by Detroit diesels gm division. You are thinking of the gm lf9 diesel that was based of a gasser design
Supposedly it's not unheard of for the crankshaft to break. They have weak crankshafts. At least the early versions anyway. They were also known for glow plug failure too .
Yeah that is because they were designed to have a forged crank but general motors cheaped out and put a cast iron crank in and the reason that the crankshaft fails is because the harmonic balancer fails, because the crankshaft is made out of cast iron it relies heavily on the harmonic balancer to not grenade itself so to fix that issue you get a fluid damper and fluid dampers don't fail as soon as a regular rubber harmonic balancer. I have one on my truck
Really cool to see that vintage of truck being appreciated, especially by what sounds like a pretty young guy. I'm early 50s now so this was a childhood time truck for me (my parents had 1978 & 1980 Blazer's at the same time from new but just Gas versions). Not sure if the 2002 is your birth year or what but that would make you older than I thought from just hearing you, Either way, I just got a 2007.5 DURAMAX pickup that I love but 50% of people act funky like "why don't you have a new $65K - $90K truck?" Well it's my 4th vehicle for 2 drivers and just pulls a camper or some hauling work. Anyway, just think it's really cool to see a guy younger than me I think, have such love and appreciation for what is still a working, strong useable truck. My 1st vid but I;m going to look through more.
awesome truck but FAIL on converting the vents.. A/C is a must in summer and that means no vents for driver.. ha! no way on that.. great truck though.. i love the 6.2
Don't got ac anymore the AC compressor bracket broke off, apparently it's a pretty common problem with the 6.2s. but it's like the same as my old Scottsdale suburban that didn't have dash vents so it's still an upgrade I don't usually have my vents pointed at me anyways and thank you!
@@compressorhead02 I wouldnbt have no A/C.. yeah broklen brackets were an issue.. the R4 compressor vibrated horribly and caused breakage.. fit a new SANDEN conversion bracket on and have A/C... I been looking for square body of diese lor gas and seems everyone rips out the A/C.. must be some kind of man initiation thing or something to have a truck without A/C.. LOL..
Not starting on the first crank used to happen to me all the time until I read the starting instructions on the underside of the visor which say to give it about half throttle while cranking. Which makes sense when you have a mechanical lift pump.
Typical diesel lol. Good trucks and solid motors (with exceptions), but man they sure hate the cold! Got a 7.3 diesel and after having one and driving one wouldn’t want anything thing for a daily driver.
I had the exact same beast. Super rough to start in below zero weather. Ended up having to replace the 24v starter, got one with a warranty. A week later I ran it out of fuel. Found out it started in gear. That starter had so much power, I drove it with the key 2 blocks to gas station and actually shifted to second gear.
There's an interesting film on RU-vid called Detroit Diesel 6.2 training. You can't kill these damn things, they'll be around when everything else is gone! And they're slow as hell. Got to love them though!
I had a few of these motors back in the day. The first thing to go was the automatic glow plug relay. Second was one or more glow plugs. (Had a glove box full of spares). Third thing to go was the starter motor. The fourth thing to go was the can of starting fluid you keep between the seats.
Clean install on those switches, buttons and panels. Mine will cycle the glow plugs at start up if cold, but lately my controller has been acting daffy, it'll cycle the glow plugs if I hit a bump. Last month I was on a really bumpy road, and the glow plugs were on for about an hour while I was driving down the road. I'll probably replace the controller with a button.
Great looking truck just like the fall guy's truck, Colt Seavers. Wondering if the transfer case is a New Process 205 gear drive, or a N.P. 203 full time?
If you spend more than 30 seconds researching you would know that general motors and Detroit Diesel designed the engine together it is a general motors/Detroit diesel engine
@@compressorhead02 I can't argue with you there bud, I do see now what you're saying. However, that makes no sense to me. First off, General Motors Corporation owned and built Detroit Diesel since the late 1930's. They were not two separate corporations. GM built Detroit Diesel for their own heavy truck division and also sold these engines for other heavy truck manufacturers, equipment manufacturers and Marine applications. The 6.2 Diesel is a light truck engine which sits in the middle of the 350 Diesel and the 6.5 turbo diesel. All 3 of these engines were in fact designed, built and distributed by GM, just as Detroit Diesel was, which is now owned by Daimler engine works. Detroit Diesel engines were a 2 stroke design up until 1987 when the first 4 stroke was introduced, the series 60, and it states in the Wikipedia under Detroit Diesel that the series 60 was in fact the first 4 stroke Detroit engine. So, the 6.2 being a Detroit? That would mean that would be the first 4 stroke Detroit. And those came out in the early 80's. Not the same thing.
@@jasondrinovsky7962 Wikipedia shmikipedia, you believe that leftist drivel ? It's a Detroit diesel based light duty engine, nothing special, kinda like the Cummins 5.9, nothing special, school bus engine, civil service plain wrap.
@@jasondrinovsky7962the engine was designed by Detroit diesel and gm just because it wasn't manufactured by Detroit diesel don't mean it isn't a Detroit diesel
@ashtonmo2002 That makes no sense. So, is the 350 diesel before the 6.2 also a Detroit just because it says GM on the block? No, it's a 350 gas motor converted to a diesel engine. Now I realize the 6.2 was built solely as a diesel engine. Since you're so confident that this is a Detroit Diesel engine, which I've never heard true and so many other people I've talked to never have either. Now I did have one guy tell me some of the technology when building that engine design was based off of a Detroit engine for the light truck division. Now that might be true, but does not make it a Detroit. I want you to get under the hood of that pickup there and find one factory stamp in the block that says Detroit Diesel and post that for everyone to see and I will apologize for ever arguing with you about this subject.
The whole point of a glow plug is for it to be glowing hot. Letting it cool down defeats the purpose. At 20°F, 30 seconds of glow plug is probably more appropriate.
@@jeffconner2007 they were built for general motors by Detroit diesel though. And they were not a piece of junk. They were quite fuel efficient and reliable for a couple hundred thousand miles if you didn't abuse them. I have been around them my when life and I can say there are many motors that are much worse. Yes, they arent a 12 valve Cummins but they were a good motor for their time.
I had an 82 Silverado 1500 that got about 25 miles to the gallon at 75 miles an hour. It would bury the speedo and then some. Dual exhaust. The 4 speed auto trans. was garbage though. Loved that truck till it blew a head gasket. That was the beginning of the end for that truck but I loved it till then.
Pretty good! You can hear it starts hitting on a couple cylinders immediately. I had a 6.2 with terrible glowplugs. Before I changed them, I'd cycle it 2-3 times and it was still 15-20 seconds of cranking. One or two cylinders hit right away, but the rest would lag. After the plug change it starts a bit better than yours
Enjoy that thing while it lasts... I noticed youre from Washington and theres a shit ton of snow. You guys up north like putting salt on the road and you have no idea how fast that will rust metal. Nobody up north has classic vehicles youre one in a billion. 😂
You make a comment regarding the glow plugs, "you don't want cold fuel on hot glow plugs"! That's exactly what you do want, that's their whole purpose, to be red hot when the fuel is strayed in. In sub freasing temperature I would glow for 10 seconds and crank while still holding the glow button. It will probably start instantly. Be less load on the starter and battery.
I have the 2wd 3/4 ton version, , it only has 65,000 original miles but the body is garbage cause i live on the coast, so its super salty, what do you think its worth?
As an aside, as a diesel owner, you should know not to call it a 'throttle'. Better to call it an accelerator, or, like some oldtimers do, a foot feed.
My Mercedes diesel failed in the subfreezing weather. Then I changed the 11 year old battery and she turned over like new. The glow plugs also heated much faster. I have never had an 11 year battery before. I hope the new one gives the same. Its the same model Varta but without the OEM star logo.
The glow plug timer keeps them on after the truck has started. You need to learn how to start an old diesel, could have been running on the first time you turned it over.
