How do you replace the water pump on a 1993 Honda Accord EX?

Answer 1

First of all it involves removing all of the belts. The lower splash guard has to be removed to gain access to the crankshft pulley. The crankshaft pulley bolt needs to be removed. ( Note: THE CRANKSHAFT BOLT IS VERY TIGHT AND USUALLY NEEDS TO BE REMOVED BY A 1/2" DRIVE PNUEMATIC IMPACT WRENCH ) The crankshaft pulley will turn as you try to loosen the bolt so you need to gain access to the transmission's flwheel and wedge a prybar or similar tool between the transmission housing and the flwheel's teeth. Then you can loosen the crankshaft pulley bolt counterclockwise. Next you will need to remove the engine valve cover to be able to remove the upper timing cover. Remove the upper and lower timing covers to gain access to the timing belt and other components inside. Remove the number one spark plug and put a long thin screwdriver or equivalent into the spark plug hole to assist in setting the engine to the number one cylinder top dead center position. Rotate the engine in a clockwise direction until the timing marks on the camshaftgear line up with the head ( Note: BE SURE TO POSITION THE UP MARK STAMPED ON THE GEAR TO THE TOP ) Make sure the lower timing marks on the crankshft sprocket lines up with the mark on the engine block and that the camshaft marks also line up. Once all the marks are lined up, loosen the timing belt tensioner bolt only( DO NOT REMOVE) until there is slack in the timing belt and tighten the bolt slightly. Remove the timing belt and then remove the bolts that attach the water pump to the engine block. Installation is the reverse of removal.
