How do you change a timing belt on a 1990 ford escort gt 19l?

Jack up the RF corner of the vehicle and remove the RF wheel. Remove the front motor mount located on the right fender apron and support the engine by the oil pan using a floor jack with a block of wood(You will now be able to jack the engine up and down as you need to). Remove the serpentine belt and if there is a belt tensioner in the way of the timing cover, remove it too. Remove the crankshaft pulley and remove the timing cover. Remove the old belt, and it is recommended that you replace the water pump at this time as well. Line up the crankshft timing mark (the keyway will be pointing straight up), and line up the camshaft timing mark(an arrow cut into one of the windows of the gear lines up witha dot on the cylinder head). Install the new belt ad reaasemble in the reverse order as disassembly. i had found eaven with the mount disconected i coud not lower the moter far enough to get anything on the crank pully bolt so i ended up cutting the weel well and bending it up so i could.
