CORRECT! I asked my boss and he Googled it also, I NEVER would have thought that was a temp sensor for emission reasons
That is one sharp truck! I have a '70 Chevy 3/4T Longhorn that weighs a lot. I want to get it to the scales one day. With 402BBC/400THM and 3.56 rear gears, it's set up for pulling a travel trailer. As a Longhorn it has the 1T frame, so it's way beefy.
Are you sure that ambient air temp sensor is for emission? It could be but it’s in an unusual place for it.
I have 4 chevys. I have an 85 k2500 GMC, a 2009 3500hd, 2011 2500hd and a 2019 2500hd. The frame on the 85 is laughable. My friend has a Military truck from the 80s and it's much beefier than mine. Still not comparable to today's trucks though. My 2009 3500hd is the next weakest truck I own. The frames were redesigned in 2011. They are boxed in now and the axles got bigger. The famous 8 bolt Chevy pattern changed in 2011. These truck are incredibly beefy. You can put several thousand pounds of cargo right in the bed. Plus the 6.0 engine is legendary. I love the new stuff.
That 12a164 basic engineering number is derived for use in emission or anything to control drivability like EEC system. Later model cars/ trucks, even automatic temperature control. God I miss Fords numbering system. So easy to figure out. Every number and letter means something.
It IS weird Apparently it’s for spark timing or something like that. Ford is different for sure. It is interesting to me to see how they did stuff back in the day
Back around 2000 I passed stalled Chevy 3500 dually "Aren't all 3500 series duallys?" laying sideways. Couldn't tell you the year but it looked kinda new. It had been towing a pretty big open car trailer with if I remember correct it had at least 6 cars on it. It was BIG and had a car on the part on the trailer that went over the cab bed. Half way across the street I see the right rear double tires still bolted on the drum and about half of the axle was still sticking out on the wheels. Smoke was coming from both the wheels and axle tube on the bearing areas, I'm guessing the axle snapped as it came out and the weight of the back snapped it? The driver might of just come off the highway as he felt and heard it making weird noises. I don't know how that truck wasn't pulled over for over weight tow.
I see lots of duallys towing 4,5,6 vehicles, I’m thinking “man that’s a load” They’re really working these late model 1 ton diesel duallys, that what I like to see tho! They weren’t made for turbo whistle and “rolling coal” they were made for WORK
Interesting to hear that the sheet metal is thicker on the newer trucks. I would have though that, like cars, it was thinner. I know my '68-'72 GS cars had what seemed to be thicker sheet metal than my '87 T-Type. Cheers!
Not to toot Ford again. But that’s the exact reason they came out with the semi floating axle. No load stress on the axle what’s so ever. All on the heavty hub. Great idea.
Me too when I compared my GS to my friends 87 GN.. This big 3500 series for the day really looked dwarfed by the car trailer. It might of even held more than 6 cars. Probably did it's think for a while but just finally gave. I'm also guessing the single car right above the cab and rear end made a big difference for failure. The tow hitch for the trailer was in the bed of the truck like you would see on a big box 18 wheeler. Pulling the trailer "should" of worked better??
The body panels are thinner on newer vehicles, but it’s High Strength Steel, what’s heavier on the newer trucks are the frames and supporting hardware PLUS all the electrical gizmos
Yeah, makes sense. All that electronic stuff scares me, actually, but eventually, if I make it that long), I will probably get an electric daily driver with all that heavy stuff on it. Still scares me--lowest bid and all. All the electric items on the '66 'vette work just fine, interestingly enough. A few new bulbs, and the clock is dead, but not a big deal. On my Buicks, I don't remember having to do any new harnesses, etc., either. For the new cars and all their complexity, computers, etc., well, it does worry me. My daily is a 15 year-old Corolla, which runs just fine. Struts and motor mounts went--SURPRISED ME!--but the electrics are just fine, what little it has. A friend told me there were companies getting ready to do assembly-line like conversions on today's gas and diesel vehicles to electric and that it will be a huge business. I guess some of today's bigger duallys etc. will go that route eventually. I can see where a guy with a fleet will not be able to buy all new electric vehicles at once and conversions may be cheaper. With the weight of the engine removed, it may make sense. Who knows? I know that gas is not going to get cheaper over the next 10 years or so and that Tesla will NOT be the biggest electric car company pretty soon. The future for us who need good gas (I use VP and even their 93 has gone from 5.00 to 7.50 already!!) for our older cars will be pretty bleak and expensive when electrics are on the road in higher numbers. Cheers!
What is REALLY scary, is on a lot of late model vehicles, I truly believe the engineers run out of places to tap power for everything. I’ve seen it in the collision industry, a body man will remove the tail lights or something in the far back of the vehicle, and the sunroof or power seats or some other electrical gizmo has to be reset in the far front of the vehicle The engineers try to rationalize it in the service manual, explaining “ the ground for the wipers is thru the left rear turn signal and license light” They didn’t plan on it I’m sure, the electrical systems are overwhelmed on newer cars.
