Donut Size on S-10

When I had my son's truck on the lift at the muffler shop today (didn't buy yet) the guy was surprised that the spare tire donut was a 16" wheel while the truck (standard 2wd S-10) has 15" wheels.  I didn't measure the overall size of the donut, but I assume the donut has a lower profile and would have a larger wheel.  Does everyone else have 16" donut wheels or did GM stick the wrong one under our truck?

Greg, my 2wd S10 has the full sized spare option, so I have a 15 inch spare with a stock full size 205/75/R15 tire, the wheel is just the stock steel wheel rather than the aluminum wheels that come standard with an LS S10.  I have since moved my tire size up to 225/70/R15, but I just will keep the stock tire size for the spare for now.

I also want to ask, what kind of exhaust work are you thinking about having done, are you going to run duals on his truck?  What kinds of exhaust systems are you looking at?  I would be interested if you do buy an aftermarket exhaust for the S10 what kinds of improvements can be made.  I wonder how the sound will be, I do not want to make my 4.3 S10 sound "ricey" or something, I'd like to be heard a little more with a nice deep tone, but nothing obnoxious, I'd also be interested in any mpg gains with an aftermarket, have you found anything out about this on the 4.3?  Thanks, I did not say this in my last message, but putting a 16 inch rim for the spare has to be a mistake, it just seems wrong...

See my other thread about exhaust details - but I'm probably going with a FM40 Delta Flow.  I'm not sure whether it will be single or dual yet.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      While waiting for parts I have been working on installing the AC compressor, new accumulator, and orifice tube. Also changed out the high side ball valve (original). The orifice tube that was in there wasn't too bad. Slightly dirty, a little bit of junk, but not blocked. Glad I changed it out.   The accumulator, which should have been a 5 minute job, may have just burned $50. Put some PAG in it, wrote the date and mileage on the side, fresh o-rings and gooey'd up the threads and rings with Nylog. Got everything connected and snugged and was going to vacuum down the system, and....   My manifold gauge won't fit on the port. It's not an R12 service port. It LOOKS like an R134 service port but the diameter is a hair too large. There's a sticker on the accumulator that says it's designed to be used with R12 and R134a systems only. So it's not R1234yf. Even if I reduced the diameter slightly with a file, the shoulder on the port is too large so the quick-connect valve won't lock on. I'm stumped. It's going back, and 50/50 on if they'll give me a refund.   Also, I did a fuel pressure test.... Key on, the gauge spikes to about 60psi and quickly bleeds off, like 2psi per second. The fuel isn't going into the plenum, no smell, starts fine, so I'm guessing there's a bad check valve in the pump and the fuel is just draining back into the tank. oh, hell. But, it shouldn't be a problem, pump primes just fine and the truck starts right up. It just means I can't really ever use fuel pressure to verify a leak at the injector or intake.

      SERCICE ESC message?

      By No F-bdy Bs · Posted

      Got this yesterday out of nowhere. Truck is a 25',6.6 gasser with 8k miles.  Only semi anomaly is that the truck had been sitting, uncranked for 6 days. Elec Stability Control showed immediately upon cranking, not while driving. No drivability issues, just the message. Battery didn't seem to be weak when cranking over.  I drove it, killed it, let it sit a few hrs with no avail.  Truck is 100% stock. No damage.

      This can be done.  It is not cheap and requires an instrument cluster swap with custom programming, new steering wheel with the controls on it, and a special jumper harness.   The cluster upgrade - 12.3” Digital Cluster Upgrade – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The wheel upgrade - Steering Wheel Upgrade Kit – 2022.5–2026 Silverado / Sierra (T1 Refresh Pickup) - WAMS   The column harness upgrade - 2019 - 2026 Silverado / Sierra: Steering Wheel LIN Bus Harness - Harness Dr. - DIY Done Right     The problem with doing all of this?  You pretty much can't have any programming done to your truck that involves the cluster ever again.  The dealer won't be able to program the cluster as GM's system will only pull data for the cluster the truck came with.  So it would be advised also to turn off over the air updates.   TLDR;  Should have bought an LT double cab?  You'd have a power seat, the wheel controls, the cluster, all things that you've been seeking in your various posts so far about your new WT regular cab.

      Yes.  The 2.7 Turbomax has Active Fuel Management.  It is NOT the same as the V8s.  Totally different system.     Here is an article from GM when the 2.7 came out explaining the cylinder deactivation and the valve lift system.  Starts at the section called "SCS Valvetrain":   New Turbocharged 2.7L 4-Cylinder Engine Powers Full-Size Trucks – TechLink         This is an internet myth going around.  It was alleged that some 5.3s had this mystical 8th digit of the VIN as an "E" which somehow meant it had a new one year only 5.3 that didn't have DFM.  The writer of said article and the person that made the claim conveniently can't count because they posted the VIN.  The 8th digit was a "D" which meant its still the 5.3 with DFM.  The 9th digit of the VIN was an "E" and the 9th digit isn't the engine code.  At all.
