This factory service and repair manual for the 1986 Chevrolet C35 covers an unchanged specification: a 4.8L inline-six or a 5.7L V8, both overhead-valve, in a two-door cab and chassis with Base trim. Unchanged does not mean interchangeable, though, because service information is written to a model year, and the figures that decide a repair, the clearances, torque values, capacities and adjustment ranges, are the ones stated for this year rather than for the one before or after.

- 5.7L V8 (350 cu in) — OHV, naturally aspirated, gasoline
Body styles covered

Known issues on the 1986 C35. The year passes without a recall, and no owner complaint is on record either. What the manual is for, then, is measurement and sequence. It states compression and oil pressure figures for the inline-six and the V8, the order and value for tightening a cylinder head, the clearance a valve train is set to, the capacities the cooling and lubrication systems take, the friction material thickness at which brakes come out, and the harness routing behind a lighting or charging fault.
THE PUSH PULL HEADLIGHT SWITCH MAY HAVE ELECTRICAL CONTACTS WHICH ALLOW AN INTERMITTENT HEADLIGHT CIRCUIT CAUSING HEADLIGHT TO FLICKER OR SUDDENLY GO OUT.
REPLACE HEADLIGHT SWITCH AS NECESSARY.
