The 1966 Plymouth Belvedere I and II service manual covers all factory engine options including the legendary Slant-6, 273 V8, and 318 V8. TorqueFlite automatic and four-speed manual transmission procedures, torsion bar suspension setup, complete wiring diagrams, brake system service, and troubleshooting for Chrysler classic B-body intermediate.
1966 Plymouth Belvedere I II Service Repair Workshop Manual
VEHICLE/EQUIPMENT INTRODUCTION:
The 1966 Plymouth Belvedere was a standout in Chrysler intermediate B-body lineup, arriving during a golden era of American automobile design when manufacturers competed fiercely on style, performance, and value. The second-generation Belvedere for 1965-1966 featured a dramatically restyled body with crisp lines, a distinctive full-width grille, and an interior that offered more refinement than its price suggested. The Belvedere I served as the base trim while the Belvedere II added upgraded interior appointments, bright trim, and optional V8 power that made it a legitimate performance contender.
Under the hood, 1966 Belvedere buyers could choose from several legendary Chrysler powerplants. The base 225 cubic inch Slant-6 was nearly indestructible and known for its smooth operation and excellent fuel economy. Step-up options included the classic 273 cubic inch LA V8 and the formidable 318 and 361 cubic inch V8 engines, with the legendary 426 Hemi available in the satellite and GTX line. The TorqueFlite three-speed automatic was widely regarded as one of the most durable automatic transmissions ever built, while the four-speed manual option attracted performance enthusiasts. The 1966 model year was particularly significant as it represented the peak of the A-to-A-body design before Chrysler downsized the B-body for 1967.
SERVICE & REPAIR SCOPE:
- Slant-6 225 cubic inch engine overhaul, timing chain, oil pump replacement
