Slip off the old belt, install the new belt (ensuring all slack is on the tensioner side), loosen the tensioner bolt to apply spring pressure, rotate the crank two full turns to equalize tension, and torque the tensioner bolt to specification. Valve Clearance Adjustment
The 5A-FE is a simple engine, but it has quirks. The distributor ignition timing, the T-VIS (Toyota Variable Induction System) on early models, and the specific torque sequence for the cylinder head are all mission-critical. A generic parts-store manual (Haynes/Chilton) gives you 70% of the info. The gives you 100%: exact bearing clearances, wiring pinouts for the ECU, diagnostic trouble code (DTC) trees, and vacuum routing diagrams. If you need help with a specific repair
: Inspect cooling and braking systems; check ball joints and steering. Every 30,000 Miles : Replace cabin and engine air filters; check fuel system. Every 60,000 Miles : Inspect drive belts and change transmission fluid. Every 100,000 Miles : Replace engine coolant and spark plugs. Resources & Manuals Digital Downloads
Here are the critical engineering torque parameters derived from standard 5A-FE documentation: Torque Specification (Nm) Torque Specification (Ft-Lbs) 29 Nm, then 49 Nm, then +90° 22 ft-lbs, then 36 ft-lbs, then +90° Multi-step sequence; always use new stretch bolts. Camshaft Bearing Caps 9.5 ft-lbs Tighten evenly from the center outward. Crankshaft Main Caps Lubricate threads with clean engine oil. Connecting Rod Caps Check plastigage clearances before final torque. Flywheel / Driveplate Use a thread-locking compound. Spark Plugs Do not over-tighten in aluminum threads. 4.
