How to Change the Timing Belt on a 1987 Acura Integra

The 1987 Acura Integra uses a 1.6L engine. This engine is an interference engine, which means that if the belt stretches past the scope of the tensioner, the valves will most likely hit the pistons and cause excessive engine damage. For this reason, Acura recommends changing the timing belt every 60,000 miles. It takes about four hours to replace the timing belt in the 1.6L Integra engine. No special tools are required.

Tools Used: Set of wrenches, Floor jack, Jack stands, Lug wrench, Set of sockets, Torque wrench

Change Timing Belt

Disconnect the battery ground cable and lay it aside, ensuring that it does not touch metal. Jack up the front of the Integra using the floor jack, then support it with jack stands. Remove the left-front wheel using the lug wrench. Remove the left-front splash guard.

Loosen the drive belt tensioners with the appropriate sockets or wrenches. Push the tensioners in toward the engine to loosen the tension on the belts. Lift the belts off the pulleys. Remove the power steering pump, but do not disconnect the power steering hoses. Just lay the pump out of the way. Remove the upper timing belt cover using the appropriate socket.

Turn the crankshaft counterclockwise until the timing mark on the crankshaft is lined up at the 11 o'clock position. Check the timing marks on the camshafts. The cams have several timing marks. In the 1987 model, the timing marks on the camshafts line up at the 12 o'clock position. If the camshaft timing marks are not lined up, turn the crankshaft one more turn and all three marks will line up.

Remove the crankshaft pulley bolt, the pulley, the lower timing belt cover and the guide plate using the appropriate sockets and wrenches. Loosen the tensioner bolt and push the tensioner away from the belt. Tighten the tensioner bolt enough to hold the tensioner out of the way. Lift the timing belt off the sprockets.

Install the crankshaft pulley and the lower timing belt cover temporarily. Check that the timing marks are still lined up. Remove the pulley and lower timing belt cover.

Install the timing belt working in a clockwise direction, starting at the crankshaft pulley. Route the timing belt up over the top of the camshafts, keeping it taut between the crankshaft sprocket and the left camshaft sprocket (as you are looking down at the engine). Route the timing belt over the water pump pulley and behind the tensioner pulley.

Loosen the tensioner bolt, allowing the tensioner to put tension on the belt. Tighten the tensioner bolt enough to hold it in place. Turn the crankshaft counterclockwise four to six turns, until the timing marks are lined up again. Turn the crankshaft until three teeth of the camshaft pass the timing mark. Loosen the tensioner bolt to allow the tensioner to put more tension on the belt. Tighten the tensioner bolt to 33 foot-pounds of torque.

Install the rest of the parts in reverse order of removal. Install the guide plate, ensuring the convex side is toward the timing belt. Tighten the crankshaft pulley bolt to 83 foot-pounds of torque.
