How to Replace the Crankshaft Sensor in Ford 150 eHow

I wondered the same thing and looked for days on end. To my surprise, there is no tension pulley for the 2003 Kia Spectra. The Kia 4 cyl has two (2) belts. The outside belt services the power steering and air conditioning. The inside belt (the one you want to service) services the alternator and water pump. The alternator tension is set by two (2) adjustment screws located on the alternator. One screw is used as a locking bolt and the upper bolt is used as the adjuster. You must first loosen the locking bolt which is located between the belt and the alternator housing. Loosen about 6 to 8 travels of the wrench (size 13mm), then tighten the upper bolt until you have no more than 1/2 inch of movement in the belt when you press down. After the correct tension is achieved, tighten the locking bolt and your done. As long as you're down there, you might as well check the outer belt as well. Same principle, one locking and one adjuster. Good Luck, Fred

there should be an adjustment bolt somewhere on the bracket. turn it one way it pulls the AC pulley towards the other pulley put the belt on then turn the adjustment bolt the opposite way and it will push it away and tighten the belt. you only want about an 1/8 inch play in the belt so the tighter the better

Remove the alternator/power steering pump and water pump drive belt to gain access to the air conditioning drive belt.
To remove and install the air conditioning compressor drive belt, first loosen the tensioner pulley lock nut, then turn the adjusting screw to raise or lower the tensioner pulley assembly Accessory Drive - 3.3L Engine or Accessory Drive - 3.5L Engine To adjust the air conditioning drive belt, loosen the tensioner pulley nut and adjust belt tension by tightening adjusting screw. Torque pulley nut to 54 N•m (40 ft. lbs.) after adjustment.
The Poly-V generator/power steering belt has an adjustable tensioner pulley located on the timing belt cover Accessory Drive - 3.5L Engine to maintain proper belt tension. To remove or install this belt, Release tension by loosening the tensioner pulley nut and adjustment bolt Accessory Drive - 3.5L Engine Reverse procedure to install and tighten belt to specified tension.

Here are the instructions to replace the belt which are ones the same as the 2.3 earlier engine.
Getting Started

• Remove the radiator shroud and loosen the water pump pulley bolts. Remove the accessory drive belts. Remove the water pump pulley bolts. Remove the water pump pulley and the radiator cooling fan. Drain and recover the Freon from the air-conditioning system. Remove the air-conditioning compressor.
  Remove the power steering pump but leave the lines attached and move aside. Remove the air conditioning bracket. Remove the crankshaft pulley bolt and the pulley using the wheel puller. Remove the timing belt cover.
  

Align Crankshaft and Block

• Turn the crankshaft clockwise until the keyway on the crankshaft sprocket is straight up and the dot to the right side of it is lined up with the corresponding mark on the block. Check that the triangle mark on the camshaft sprocket lines up with the same type mark on the block at the 5 o'clock position. If not then turn the crankshaft one more time and it will align.
  

Loosen Tensioner

• Loosen the large bolt on the top of the tensioner and then loosen the bolt closest to the tensioner pulley. Use the special ford tool and turn the tensioner clockwise to take the tension off of the timing belt and tighten the adjusting bolt lightly to hold it out of your way. Remove the timing belt.
  

Work Counterclockwise

• Install the new timing belt starting on the right side and work counterclockwise. The circle on the crankshaft sprocket and the diamond marks on the oil pump and the triangle marks on the camshaft sprocket should always stay lined up. Loosen the adjuster bolt on the tensioner and rotate the engine two turns clockwise and realign the timing marks. Tighten the tensioner-adjusting bolt next to the tensioner pulley and then pivot bolt. Install the rest of the components in the reverse order that they were removed and tighten the crankshaft bolt to 121 foot-pounds of torque.

2.7L Engine
A/C & Alternator Belt

1. Raise and safely support the vehicle.
2. Remove the right front wheel and belt splash shield.
3. Loosen tensioner locking bolt and pivot bolt.
4. Rotate tensioner clockwise to allow enough slack to remove belt

To install:

1. Install the air conditioning compressor/alternator belt on pulleys, tensioner in slack position, slip belt over idler last.
2. Adjust drive belt tension.
3. Install the belt splash shield and right front wheel.
4. Lower vehicle.

1. Before servicing the vehicle, refer to the Precautions Section.
2. Raise and safely support the vehicle.
3. Remove the right front wheel and belt splash shield.
4. Loosen the tensioner locking bolt and pivot bolt.
5. Rotate tensioner clockwise to allow enough slack to remove the belt

To install:

1. With the tensioner in a slack position, install the Air Conditioning (A/C) compressor/alternator belt on the pulleys. Slip the belt over the idler last.
2. Adjust the drive belt tension.
3. Install the belt splash shield and right front wheel. Tighten the wheel lug nuts to 100 ft. lbs. (136 Nm).
4. Lower the vehicle.
   

Power Steering Belt

1. Raise and safely support the vehicle.
2. Remove the right front wheel and belt splash shield.
3. Remove the air conditioning compressor/alternator belt.
4. Loosen belt adjusting bolt. It is not necessary to loosen the pivot bolt on the power steering pump. There is a bushing incorporated into the power steering pump/bracket that allows it to pivot.
5. Remove the power steering belt.

To install:

1. Install the power steering belt on pulleys.
2. Adjust drive belt tension.
3. Install the air conditioning compressor/alternator belt.
4. Install the belt splash shield and right front wheel.
5. Lower vehicle.

A/C Compressor Belt

1. Remove the alternator/power steering and water pump drive belt to gain access to the air conditioning belt.
   

2. Loosen the tensioner pulley locknut, then turn the adjusting screw to raise or lower the tensioner pulley assembly. Remove the belt.
   

To install:

1. Install the belt.
   

2. To adjust the belt, loosen the tensioner pulley nut and adjust the belt tension by tightening the adjusting screw. Tighten the pulley nut to 40 ft. lbs. (54 Nm) after adjustment.
   

3. Install the alternator/power steering and water pump drive belt and adjust.
   

4. Start the engine and check for proper belt alignment and any abnormal noise.
   

You need to pull out the timing cover. 4-6 hours of work. Here is the step to remove the Cover, then you need to remove the Sprockets.

1. Remove the oil pan.
2. Remove the power steering belt if so equipped.
3. Remove the air conditioning belt, compressor and bracket if so equipped.
4. Remove the fan clutch (fluid coupling), with the fan and water pump pulley.
5. Matchmark and remove the crankshaft pulley(s). This bolt will be very tight. Use the counter-holding bar, properly installed, to hold the crankshaft while loosening the bolt. Use the pulley extractor or gear puller to remove the pulley from the shaft.
6. Remove the water bypass pipe.
7. Remove the fan belt adjusting bar. If necessary, remove the lower power steering bracket for access.
8. Disconnect the heater water outlet pipe.
9. Unbolt the timing chain cover assembly. Be careful to loosen only the correct bolts.

To install:

1. Install new gaskets over the dowels on the timing chain cover. Slide the cover assembly over the dowels and pump spline. Insert the retaining bolts and tighten them. Tighten the 8mm bolts to 9 ft. lbs. (13 Nm) and the 10mm bolts to 29 ft. lbs. (39 Nm).
2. Temporarily install the adjusting bar to the alternator. Install the adjusting bar to the chain cover and tighten the bolts to 9 ft. lbs. (13 Nm).
3. Install the heater water outlet pipe.
4. Install the water bypass pipe.
5. Install the crankshaft pulley and bolt. Use the counter-holding tool to hold the pulley and tighten the bolt to 116 ft. lbs. (157 Nm). If equipped with air conditioning, install the second crankshaft pulley.
6. Install the water pump pulley and fluid coupling with the fan.
7. Adjust the tension on the drive belts.
8. Install the air conditioning compressor bracket, compressor and belt if they were removed.
9. Install the power steering belt and adjust it.
10. Attach the oil pan.
11. Install the radiator.
