1988 Acura Legend Timing Belt Installation Instructions

The Acura Legend was a series of luxury cars manufactured by Honda under its Acura brand from 1986 to 1995. The 1988 models were available with six-cylinder engines having a displacement of either 2.5 liters or 2.7 liters. The procedure for installing a timing belt is the same for both engines. The timing belt on a 1988 Acura Legend keeps the rotation of the camshaft and crankshaft synchronized, so that the cylinder valves open and close at the correct time.

Tools Used: Socket wrench set, Chain hoist, Torque wrench

Timing Belt Installation

Disconnect the cable on the negative battery terminal with a socket wrench. Detach the cover for the crankshaft pulley and the harness cover above the upper timing belt cover. Release the clamp for the engine sub-harness. Remove the support bolts and side mount brackets for the engine.

Raise and support the engine with a chain hoist. Disconnect the lower splash guard on the engine with a socket wrench. Remove the adjusting bolt on the idler pulley for the air conditioner, and disconnect the air compressor drive belt. Disconnect the mounting bolt and adjusting bolt for the alternator. Detach the drive belt for the alternator and remove the alternator.

Remove the mounting bolt and the drive belt for the power steering pump with a socket wrench. Disconnect the power steering pump. Remove the upper covers for the timing belt.

Turn the crankshaft clockwise so that the number-1 piston is at its top dead center position by aligning the timing marks on the crankshaft. Remove the bolt for the crankshaft pulley with a socket wrench and detach the crankshaft pulley. Disconnect the lower cover for the timing belt.

Loosen the adjusting bolt for the timing belt tensioner with a socket wrench. Push the tensioner to relieve the tension on the timing belt and tighten the adjusting bolt. Remove the timing belts, and adjust the crankshaft again to align its timing marks if necessary.

Place the new timing belt onto the crankshaft, front camshaft, water pump, tensioner pulleys and rear camshaft, in that order. Turn the bolt on the belt tensioner pulley a half-turn counterclockwise with a socket wrench. This allows the tensioner spring to set the timing belt tension automatically. Tighten the pulley bolt to 31 foot-pounds with a torque wrench.

Turn the crankshaft six turns clockwise so that the crankshaft and camshaft timing marks align again. Continue turning the crankshaft to align the blue mark on the crankshaft pulley with the pointer on the engine. Loosen the pulley bolt on the timing belt tensioner, then tighten it with a socket wrench.

Tighten the crankshaft pulley bolt to 83 foot-pounds with a torque wrench. Perform steps one through three in reverse order to install the remaining components. Torque the bolts for the engine side mount bracket to 40 foot-pounds.
