Engine Service Manual | Toyota 5a-fe

Replace every 100,000 km (Critical: The 5A-FE is generally a non-interference engine, but timing belt failure will cause immediate engine stalling). Valve Clearance Inspection: Every 40,000 km. Tune-Up and Mechanical Adjustments 1. Valve Clearance Adjustment (Engine Cold)

Loosen the timing belt tensioner bolt, push the tensioner pulley back against its spring, and temporarily snug the bolt down to hold it in place.

Key procedures in this section include:

Regular preventative maintenance is the secret to keeping a 5A-FE engine running past 300,000 miles. According to the factory service manual, these are the primary fluid and service requirements: Engine Oil 3.2 Liters (3.4 US quarts) Capacity (dry engine): 3.7 Liters (3.9 US quarts) Replace every 100,000 km (Critical: The 5A-FE is

: Tighten in sequence (9-3-1-6-8-7-5-2-4-10) in three passes: 22 ft-lb, then 43 ft-lb, and a final pass at 47 ft-lb. Camshaft Bearing Cap Bolts : 9 ft-lb. Camshaft Timing Pulley : 43 ft-lb. Valve Clearances (Cold) : 0.15–0.25 mm (0.006–0.010 in). : 0.25–0.35 mm (0.010–0.014 in). Timing Alignment

Slip the new timing belt onto the gears. Start at the crankshaft gear, route it tightly up the straight side past the water pump pulley to the camshaft gear, and finally loop it over the tensioner pulley.
