2004 Silverado 1500 Work Truck, 36,000 miles

 

The speedometer was reading 18 mph when at rest, engine running or off. Now it's up 61. Therefore, it reads much faster than the actual speed.

 

What causes this and what is the fix? Thank you.

My 2005 is doing the same.

Any suggested solutions?

I believe there is a recall for that, take em in to your dealers. It should be fixed for free, Its a common problem.

YUP. Sounds like the bad cluster issue. Check out the dealer.

--------------------------------------------------------------------------------

 

 

 

 

GM PARTS BULLETINS & INFORMATION - TO CADILLAC, CHEVROLET AND GMC DEALERS

 

Subject:Bulletin GMP07-174 - Special Coverage Adjustment #07187– Instrument Panel Cluster Gauge Needle FunctionMessage #:VSU20071575

DESCRIPTION:

SPECIAL COVERAGE Adjustment #07187– SEPTEMBER 28, 2007

 

DUE TO PART AVAILABILITY, THIS SPECIAL COVERAGE IS BEING ADMINISTERED IN PHASES. YOU WILL BE NOTIFIED AS EACH ADDITIONAL PHASE IS RELEASED.

 

CUSTOMERS ARE BEING INSTRUCTED TO CONTACT THE DEALERSHIP TO ARRANGE AN APPOINTMENT IF THEY BELIEVE THEIR VEHICLE HAS THIS CONDITION. THE CUSTOMER IS BEING ASKED TO PROVIDE THE VIN SO THE IPC CAN BE ORDERED IN ADVANCE OF THE SCHEDULED APPOINTMENT. THIS WILL ELIMINATE THE NEED TO KEEP THE VEHICLE OVERNIGHT.

Some customers of 2003-2004 model year Cadillac Escalade, Escalade ESV, and Escalade EXT; Chevrolet Avalanche, Silverado, Suburban, and Tahoe; and GMC Sierra, Yukon, and Yukon XL vehicles have reported that the instrument panel (IP) cluster gauges stick, flutter, or become inoperative. This may cause inaccurate readings, including the speedometer and fuel gauge.

This special coverage covers the condition described above for a period of 7 years or 70,000 miles (110,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.

Refer to Special Coverage Adjustment #07187 for further information

 

EFFECTIVE DATE:

Initial owner mailing is scheduled to begin: Phase 1 9-28-07

 

 

GENERAL INFORMATION:

Instrument panel clusters (IPC) required to complete this special coverage are to be obtained from the Electronic Service Centers. Refer to GM Service Policies and Procedures Manual, section 1.5.9, for specific procedures. To eliminate keeping the customer's vehicle overnight, customers are being told to contact the dealership to arrange a service appointment and to supply their VIN. Dealers are to pre-order the IPC identifying the part from the Electronic Parts Catalog using the VIN filter so it will be at the dealership on the day of the scheduled appointment.

1. The customer will contact the dealership to arrange an appointment and provide their VIN.

2. Contact a GM Authorized Electronic Service Center to order an exchange and arrange for delivery of the pre-exchange product.

3. All units will be shipped FedEx Ground.

4. After removal of the defective unit, return the defective core to the Electronic Service Center using the supplied pre-paid Automatic Return shipping (ARS) label.

5. Failure to return the product within 30 days to the Electronic Service Center will result in a charge to the Dealer's Open Parts Account.

 

 

Also note if you are outside the mileage limits there are several cluster rebuilders

on e-bay that will replace the stepper motors (thats the part that fails) for around

$150 bucks.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
