The 1992 Honda Civic LX uses the 1.5L and 1.6L engines. The timing belt replacement process in both engines is the same. Both engines are interference engines. The timing belt should be changed every 90,000 miles or 72 months, according to Honda, as the previous use and history of these engines show that the belt stretches past its useful life at this interval. Should this happen, more likely than not, the valves will hit the pistons and cause extensive engine damage.
Disconnect the battery ground cable and lay it aside. Do not allow the cable to touch metal. Raise the front of the Civic and support it with the jack stands. Remove the left-front wheel using the lug wrench. Remove the left-front inner bumper splashguard using the appropriate socket.
Support the engine by pushing the floor jack under the oil pan and jacking it up so it just touches the pan. Release tension on the accessory drive belts by loosening the slider bolts and pushing the component away from the belt, or by pushing the tensioner away from the belt with a wrench. Lift the belts off the pulleys.
Remove the top engine mount, the timing belt cover and the valve cover using the appropriate sockets. Turn the crankshaft counterclockwise until the timing mark on the crankshaft pulley lines up at the 1 o’clock position. The camshaft timing marks should also be lined up. If your engine ID is B20A3, D15B2, D15B6, D16A6, D15B7 or D15B8, the camshaft sprocket timing mark lines up with the upper surface of the cylinder head (12 o’clock position). If your engine ID is D15Z1, the timing marks are at the 9 o’clock and 3 o’clock positions; and if the engine ID is D16Z6, the timing mark is at the 7 o’clock position.
Remove the crankshaft pulley bolt using the appropriate socket, then pull off the crankshaft pulley. Remove the lower timing belt cover using the appropriate socket. Loosen the timing belt tensioner bolt. Push the tensioner away from the belt. Tighten the bolt just enough to hold the tensioner out of the way. Lift the timing belt off the sprockets. Check that all the appropriate timing marks are lined up.
Install the timing belt, starting at the crankshaft pulley. Route it over the top of the camshaft pulley, keeping it tight between the crankshaft and camshaft sprocket. Route it over the outside of the water pump pulley and behind the tensioner pulley.
Loosen the tensioner bolt and let the tensioner put tension on the timing belt. Tighten the tensioner bolt. Turn the crankshaft counterclockwise four turns, until the timing marks line up again. Loosen the tensioner bolt, allowing the tensioner to put tension on the belt. Turn the crankshaft counterclockwise until the camshaft turns three teeth.
Tighten the tensioner bolt to 31 foot-pounds of torque if your engine ID is B20A3. Tighten the tensioner bolt to 33 foot-pounds of torque for any other engine ID. Install the rest of the parts in reverse order of removal. Oil the threads and the face of the crankshaft pulley. Tighten the crankshaft pulley bolt accordingly: Engine ID B20A3--108 foot-pounds of torque; B15B2, D15B6, D16A6--119 foot-pounds of torque; D15B7, D15B8, D15Z1 and D16Z6--134 foot-pounds of torque.
