Looking rearward towards front of engine from in front of radiator, which way, CW or CCW, does 87Ford Ranger2.9L crankshaft (fan & pump) turn?


fan clutches are Left hand thread as they tighten up when the engine is running. If they were right hand thread then when the fan is working they would come loose off the shaft
In short undoing then actually tightens them

  • Place the drain pan under the radiator drain plug, open the plug and allow it to drain. Close the plug. Loosen the four nuts on the water pump pulley but do not remove them yet. Loosen the adjusting bolts in the alternator and the power steering pump with a wrench, push them away from the belts and remove the belts.
  • 2Remove the bolts securing the fan shroud to the radiator support using a 10 mm socket. Remove the four nuts on the water pump pulley, then remove the fan and shroud as an assembly. Remove the bolts in the crankshaft pulley using a socket. Loosen and remove the crankshaft bolt using a socket.

    • 3

  • Remove the top radiator hose. Extract all the 10 mm bolts securing the top and bottom timing covers and remove the covers.
  • 4Install the crankshaft bolt temporarily. Use a socket on the bolt and turn the crankshaft clockwise until the mark on the crankshaft sprocket aligns with the timing mark on the block at the 12 o'clock position. Look at the camshaft sprockets and make sure the left sprocket has the "I" facing straight up and the right sprocket has the "E" facing up. At the same time, notice that there is a line on each sprocket adjacent to each mark--make sure they line up with the notch on the cylinder head at 12 o'clock. This allows for perfect alignment. If they do not come close to aligning, rotate the crankshaft one more time and they will align.
  • 5Loosen the tensioner bolt and push the tensioner away from the belt. Loosely tighten the bolt to maintain position. Remove the belt.
  • 6Install the new belt starting on the right side away from the tensioner. Keep all the tension on the right side. Loosen the tensioner bolt and allow it to apply tension on the belt. Do not tighten the bolt yet. Rotate the engine two turns clockwise and re-align the timing marks. Tighten the tensioner bolt to 35 foot-pounds.
  • 7Install the timing belt covers. Remove the crankshaft bolt and install the crankshaft pulley. Reinstall the bolt and tighten. Install the radiator shroud and fan as an assembly. Place the fan on the water pump pulley, install the four nuts loosely, install the bolts in the fan shroud and tighten.
  • 8Install the belts around the crank pulley, water pump pulley and alternator and pull the alternator up to tension the belt and tighten the bolts using a socket. Tighten the water pump pulley nuts using a wrench.
  • 9Install the belt on the power steering pump, pull the pump out to tension the belt and tighten the bolts. Install the upper radiator hose. Fill the radiator with antifreeze

    My water pump is leaking i guess some screws are loose.. What should i do.. To fix it myself?


    well if your leaking from your water pump it shouldnt be the screws loose. there is a weepm hole that when that leaks it means your ater pump is bad. but if the screws are loose just get a socket set an ratched an extention an tighten them up. the water pump is the pulley that has the fan on it.

    Im changeing the water pump on a 199 gmc 3500 and I cat get the cooling fan off. There is a large nut attaches the fan to the water pump that turns everything but wont break free. what is the trick?


    You can get the special tools to remove it or some people take a air hammer with a pointed bit and give the edge of the nut a quick hit in the direction the fan spins to break loose the nut.And to tighten it thread it back on half way then start the engine and when it spins it will tighten it up.
