A/C Belt Tensioner Bolt Replacement - Cross-Reference Part Number

Body/Interiorbeginner✓ OP Confirmed

Problem

During engine rebuild on a 1987 Supra Turbo, the A/C belt tensioner bolt was found to be bent. The bolt is not listed as a standalone part in Toyota parts diagrams for the 86.5-88 model years, making replacement difficult to source.

Root Cause

The A/C belt tensioner adjusting bolt had become bent over time (discovered at 135k miles during head gasket rebuild). Toyota does not list the bolt as a separate part number in the earlier 1986.5-1988 parts illustrations, only in later model year diagrams.
