How to Install a Water Pump on a 1992 Acura Integra 1.8L
- 1). Disconnect the negative battery cable and set it aside, making sure that it does not touch metal. Jack the front of the Integra up with the floor jack and support it with the jack stands. Remove the left wheel using the lug wrench. Remove the splash guard using the appropriate socket. Place the drain pan under the radiator petcock. Open the petcock and allow the antifreeze to drain. If you use a clean drain pan, you can reuse the antifreeze.
- 2). Loosen the tensioner on the accessory drive belts, then lift the belts off the pulleys. If the drive belt is tensioned with a slider on the accessory’s bracket, loosen the slider bolt and, if equipped, the lock nut, and slide the accessory toward the engine to loosen tension on the belt. If the belt uses a tensioner with a pulley, use a socket to push the pulley toward the engine to loosen tension on the belt.
- 3). Tighten the tensioner bolt to 40 foot-pounds of torque. Install the rest of the parts in reverse order of removal. Tighten the crankshaft pulley bolt to 130 foot-pounds of torque. Tighten the radiator petcock and refill the radiator. Reconnect the battery negative cable.
- 4). Unbolt the power steering pump, but do not remove the hoses. Pull the power steering pump away from its bracket and lay it out of the way. Remove the valve cover using the appropriate sockets. Place the block of wood on the floor jack and slide the jack under the engine’s oil pan. Jack it up just so the wood touches the bottom of the oil pan, to support the engine. Remove the left engine mount using the appropriate socket.
- 5). Turn the crankshaft counterclockwise until the timing marks line up. The 1992 Integra uses three sets of timing marks. The timing mark on the crankshaft pulley should line up at the 11 o’clock position. There are two sets of marks on the camshafts. Looking down at the engine, find the line on the left camshaft sprocket. It should be in the 3 o’clock position. It lines up with the line on the right camshaft sprocket, which should be at the 9 o’clock position. The second set of marks, the camshaft UP marks, should be at the 12 o’clock position on both camshafts. If the crankshaft pulley timing mark lines up but the camshaft marks do not line up, turn the crankshaft counterclockwise once more, and the marks should line up.
- 6). Remove the crankshaft pulley using the appropriate socket. Remove the timing belt covers using the appropriate socket. Loosen the timing belt tensioner bolt, then push the tensioner away from the belt. Tighten the bolt to hold the tensioner out of the way. Lift the belt off the pulleys.
- 7). Unbolt the water-pump-to-engine bolts, then pull the water pump and the drive sprocket off as an assembly. The new pump comes with a new sprocket. Fit the new O-ring in the water pump.
- 8). Bolt the new water pump onto the block. Tighten the 6mm bolts to 9 foot-pounds of torque. Tighten the 8mm bolts to 16 foot-pounds of torque.
- 9). Reinstall the lower timing belt cover and the crankshaft pulley. Make sure the timing marks are still lined up. If your engine is a B18A or B18B1, move the camshafts enough to insert a 5mm pin into each camshaft front bearing cap, to locate the camshafts. For other engines, just make sure the timing marks are lined up. The engine identifier is found on the sticker on the radiator shroud or the underside of the hood.
Remove the crankshaft pulley and the lower timing belt cover. Working clockwise, route the timing belt around the pulleys, starting at the crankshaft. Work your way over the top of the left camshaft, keeping the belt taut between the crankshaft sprocket and the camshaft sprocket. Route the belt over the right camshaft sprocket, in front of the water pump pulley, and behind the tensioner.
Remove the two 5mm pins if you installed them. Loosen the tensioner bolt to allow the tensioner to put tension on the belt. Turn the crankshaft counterclockwise four times until the timing marks line up. If they do not line up on the fourth rotation, turn the crankshaft two more times and the marks should line up. Loosen the tensioner bolt again, to allow the tensioner to put more tension on the belt. Turn the crankshaft counterclockwise until the camshaft sprocket timing mark is three teeth past the mark on the head.
