Service bulletin 20-001

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

UBJECT: 4P10 Engine Repair vs. Replacement Worksheet MODELS: FEC52, FEC72, FEC92, FGB72 DESCRIPTION: When repairing engine damage, dealers are expected to follow the most economical repair method, regardless of whether the repair is within warranty or is customer pay. If the vehicle is within warranty coverage, and the damage is severe enough to question whether an engine repair is the most economical solution, the dealer must open a Technical Assistance Request (TAR) and submit a 4P10 repair cost comparison worksheet. The Technical Support Center will review the worksheet and the information outlined for 4P10 engine failures in SIB 19-005, and will provide repair guidance accordingly. The worksheet is located in the TSC Resource Center under “4P10 Cost Simulator for repair vs replacement”, and under Service-Publications-Service Forms-“MFTA-4P10WS”. Please note that MFTA supplies large engine components such as cylinder blocks, short engine assemblies, etc. for 4P10 engine repairs when a complete engine assembly replacement is not essential.
