Reproduction GM 10085701 Accessory Drive Belt Routing Label – 1988-1990 Chevrolet S10 & GMC S15 4.3L

Description

Restore the Original Underhood Belt-Routing Information

This factory-style reproduction replaces a faded, damaged or missing GM 10085701 accessory drive belt routing label. The artwork was recreated from an original label documented on a 1989 Chevrolet S10 pickup equipped with the 4.3L V6.

GM parts catalogs also associate reference number 10085701 with the corresponding GMC S15 and S15 Jimmy 4.3L applications. The label preserves the original black-and-white layout, accessory-drive pulley diagram, part number and “WITHOUT A/C” routing callout.

The original GM service label is discontinued, making an accurate reproduction useful for engine-bay restoration, detailing and replacement of an original decal that has faded, peeled or become unreadable.

Primary Fitment

• 1988–1990 Chevrolet S10 pickup with the 4.3L LB4 V6, VIN code Z
• 1988–1990 GMC S15 pickup with the 4.3L LB4 V6, VIN code Z

Catalog-Supported Exact-Match Applications

• 1988–1990 Chevrolet S10 Blazer with the 4.3L LB4 V6
• 1988–1990 GMC S15 Jimmy with the 4.3L LB4 V6
• Both 2WD and 4WD configurations when the original GM number and complete routing diagram match

Fitment rule: Do not order by model year or engine displacement alone. Accessory-drive routing can vary with the engine, air-conditioning system, air-pump equipment, alternator, power-steering equipment and other installed accessories. Compare GM reference number 10085701 and the complete pulley arrangement with the original vehicle.

Understanding the “WITHOUT A/C” Callout

The words “WITHOUT A/C” are part of a specific alternate-routing callout within the original diagram. They should not be used by themselves to determine whether the label fits a vehicle.

Match the complete illustration and original part number rather than relying only on whether the truck currently has air conditioning. A vehicle may also have been modified during its service life, including an A/C-delete pulley, accessory relocation or engine replacement.

Other Possible GM Applications

GM reference number 10085701 appears in parts catalogs for additional 1988–1993 GM truck applications. Those vehicles should be treated as exact part-number and exact-artwork match applications unless specifically identified in the primary fitment list above.

If your original label shows a different part number or a different pulley layout, do not assume the diagrams are interchangeable. Submit a photograph and dimensions through the GMT Central custom label request page.

Trim-to-Fit Construction

The label is intentionally supplied trim-to-fit. This allows the final edge to be cut closely around the printed border before installation.

Use sharp scissors or a precision craft knife, a straightedge and a protected cutting surface. Complete all trimming before removing the adhesive backing.

Installation

1. Compare the new label with the original part number and complete routing diagram.
2. Test-fit the label at the original underhood location.
3. Trim carefully around the outside edge while the backing remains attached.
4. Remove the old label and as much remaining adhesive as possible.
5. Clean the mounting surface and allow it to dry completely.
6. Peel back a small portion of the backing and align the label before full application.
7. Apply the label gradually from one side to the other.
8. Press outward while applying to reduce trapped air.
9. Press firmly across the entire label, especially around the edges.

Apply only to a clean, smooth and dry surface. Do not install the label directly against an exhaust component or another extreme-heat surface.

Frequently Asked Questions

Does this label fit a GMC S15 with the 4.3L engine?

Yes. GM reference number 10085701 is cataloged for 1988–1990 GMC S15 4.3L LB4 applications. Verify that the original vehicle uses VIN engine code Z and that the complete pulley diagram matches this reproduction.

Does it fit the GMC S15 Jimmy?

The label is catalog-supported for corresponding 1988–1990 GMC S15 Jimmy 4.3L LB4 applications. Compare the original number and entire routing diagram before ordering.

Does it fit both 2WD and 4WD vehicles?

The part number appears in both 2WD and 4WD S/T-series catalogs. Drivetrain alone does not establish fitment, so the original part number and diagram must still match.

Is this label only for a vehicle without air conditioning?

The phrase “WITHOUT A/C” identifies an alternate path shown within the routing diagram. Do not use A/C status alone as the fitment test. Compare the complete pulley arrangement and GM reference number.

Is this an original General Motors label?

No. This is a new aftermarket reproduction manufactured for GMT Central. It is not a genuine GM or New Old Stock service label.

Is the label pre-cut?

No. It is supplied trim-to-fit so the installer can create a clean final edge around the printed artwork.

Can it be installed on a later GMC Sonoma?

GM reference number 10085701 appears in some later S/T-series catalogs, but later vehicles may have different engines or accessory arrangements. Order for a Sonoma only when the original label number and complete artwork match exactly.

Where should the label be installed?

Install it at the vehicle’s original underhood label location. Placement can vary, so use the remaining original label, adhesive outline or vehicle-specific reference photography as a guide.
