# REMANUFACTURED TBI FUEL INJECTORS (APPLICATION)

#### MODELS: 1985-86 S/T, M-VAN, AND CABALLERO WITH 2.5L, 2.8L, 4.3L ENGINES EQUIPPED WITH TBI

Remanufactured Fuel Injectors (see Figure No. 1) for General Motors vehicles equipped with Throttle Body Injection (TBI) were available from WDDGM beginning March 1, 1986. The new line of Remanufactured Injectors will cover all GM vehicles with single point (2.5L) and dual point (2.8L and 4.3L) TBI for model years 1985-1986. An application chart is attached. Remanufactured TBI Fuel Injectors are the recommended choice for new vehicle warranties requiring an injector replacement. These injectors meet the same specifications as the new injectors they replace. After March 1, 1986, dealers should order Remanufactured Injectors to be used for warranty; however, new injectors may still be used until inventory is depleted. Beyond vehicle warranty, the injectors are warranted for 90 day and/or 4,000 miles. In order to help dealers return the core injectors in good condition, a two-tube package was designed (see Figure No. 2). The inner tube contains the injector and all of the additional parts and instructions necessary to install the remanufactured injectors. The outside tube MUST be used to return the old injector to obtain core credit. The procedures for removal and installation the injectors can be found in section 6E2-C2 of the S/T and M-Van Service Manuals.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
