Vehicles Covered: Hyundai Sonata 2002-2004 (2.4L & 2.7L Engines)

In 2003, Hyundai produced two types of Sonata:
Available engines:
4 Cylinders 2.4L VIN "S", MFI DOHC - see Figures 1 and 3.
6 Cylinders 2.7L VIN "H", MFI DOHC - see Figures 2 and 3.

To differentiate between these types of 2003 Hyundai Sonatas, the VIN 8th digit (Engine Type) will either be "S" or "H" as in the table above.

To locate the Engine drive belt, jack up the vehicle & place it onto jack stands, then slide under the car (toss a cardboard mat down first), then, once under the car, remove the (plastic) engine splash shield. Once removed, the drive & accessory belts are easily observed.


Fig. 1 Accessory Drive Belt Routing 2.4L (4 cyl) Engine - Hyundai Sonata
The "COMPRESSOR" refers to the A/C compressor, and "GENERATOR" refers to the Alternator.


Fig. 2 Accessory Drive Belt Routing 2.7L (6 cyl) Engine - Hyundai Sonata
The Belt Routing on the Left is "With A/C", on the Right is "without A/C"

Inspection - Drivebelt and Accessory Belts

Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. Worn or damaged drive belts should be replaced.

Drivebelt Removal & Installation - 2003 Sonata (2.4L and 2.7L engines)

Raise and support the vehicle.
Remove the engine splash shield.
Rotate the drive belt tensioner clockwise to release the drive belt tension.
Remove the drive belt from the alternator.
Slowly release the drive belt tensioner.
Remove the drive belt from the accessory drive pulleys.

To install:

Install the drive belt to the accessory drive pulley.
Rotate the drive belt tensioner clockwise.
Install the drive belt to the alternator.
Ensure the drive belt is properly aligned and seated into the grooves of the accessory drive pulleys.
Slowly release the drive belt tensioner
Install the engine splash shield.
Lower the vehicle.

Here's the best illustration I can find of the Hyundai 2.4L and 2.7L engines - the drivebelt seems to be located on the passenger side of both of these transversely mounted engines.

How do you make the tensioner release to tighten the timing belt?

The belt tensioner keeps the belt tight inside each accessory pulley while the engine is running. The tensioner is made up of a spring-loaded arm. If the spring inside of the tensioner becomes loose then it will not be able to hold the belt properly.And belt will also get loose. The belt tensioner is on the engine underneath the alternator. Its fitted by bolt.To loose the belt you will need drive socket and breaker bar .Turn the breaker bar counterclockwise to release tension from the belt.Remove the mounting bolt at the top center of the tensioner arm.The tensioner arm is loose and will easily come out.If you in-case are to replace the tensioner then place the new tensioner in same place and tighten the bolt which you removed.Before removing or moving the belt check the position of the belt passing from each that when you fit the parts there is no problem in fitting the parts.
After its done.Start the engine and see that belt and tensioner runs freely and belt moving from each pulley smoothly.

The tensioner seems to have sliped is it beyond repair of can i just retightin it

if the tensioner has slipped and not tensioning the belt enough then it's probably broken and must be replaced. Belt Tension The belt is automatically adjusted using a spring loaded tensioner. If belt slippage is suspected or unusual belt noises occurs, the following procedure should be used to determine if the tensioner or belt is at fault.
  1. Start the engine and allow it to warm up to normal operating temperature with all accessories (such as the A/C) turned ON; this should take approximately 10 minutes. If the vehicle is equipped with power steering, turn the steering wheel to the left and right several times during warm-up to make sure a proper load is placed on the belt.
  2. Turn the engine and accessories OFF.
  3. Using a 14mm or 9⁄16 in. wrench, depress the tensioner arm until the belt becomes loosened, then slowly allow the tensioner to return to position and apply tension to the belt. Do not allow the tensioner to snap against the belt.
  4. Inspect the markings located on the tensioner arm. If the marks on the arm fall outside the operating range, the drive belt must be replaced. NOTE: Inspection of the belt using a tension gauge must be performed with the upper engine mount removed.
  5. Using tool SA9181-NE or an equivalent calibrated belt tension gauge, measure and note the tension readings at the 2 points located centrally between 2 belt pulleys as shown in the illustration. The dotted lines represent other possible paths which your belt may follow, depending on the engine and accessories with which your vehicle is equipped.
  6. Repeat the measurements from the previous step 2 more times, then calculate the average result for each test location. The readings should be 50–65 lbs. (22.7–29.2 kg) for new belts or a minimum of 45 lbs. (20.4 kg) for used belts. If the readings are out of this range or do not meet the minimum and the drive belt passed the test in Step 4, the drive belt tensioner must be replaced.

    NOTE: The A/C drive belt self tensioner is NOT a dynamic tensioner. After adjustment the tensioner bracket bolts are tightened. The torsion spring is no longer responsible for tensioning the A/C belt. The torsion spring is only used for initial belt tensioning.
    1. Remove generator/power steering belt to gain access to A/C belt. Refer to GENERATOR/POWER STEERING BELT for procedure.

    1. Loosen BUT DO NOT REMOVE tensioner locking bolt and pivot bolt (Fig. 2).
    2. Insert 1/2" drive breaker bar into square opening on belt tensioner. Rotate tensioner counterclockwise until belt can be removed from pulleys (Fig. 2).
    3. Slowly rotate tensioner clockwise to relieve spring load.
    Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt.

    Belt replacement under any or all of the following conditions is required:
    • Excessive wear
    • Frayed cords
    • Severe glazing
  • Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 3).

    Do not use any type of belt dressing or restorer on Poly-V Belts. INSTALLATION


NOTE: Verify that torsion spring position is in the new belt position before installing a NEW belt (Fig. 4). If torsion spring is not in the new belt position, follow steps 1-7 to change the tensioner spring from the USED belt position to the NEW belt position.
  1. Insert a 1/2" drive breaker bar into the square opening on the tensioner. Hold counterclockwise pressure on tensioner while removing the locking bolt (Fig. 2).
  2. Carefully release spring load of the torsion spring on the tensioner.
  3. Remove pivot bolt, tensioner, and spring from front timing cover.
  4. Insert spring arm into the NEW belt position on the tensioner (Fig. 4).
  5. Install torsion spring, tensioner, and pivot bolt.
  6. Install pivot bolt. Tighten only finger tight, at this time.
  7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
    1. Install the NEW belt by rotating the tensioner counterclockwise until the NEW belt can be installed on pulleys. See (Fig. 5) for belt routing.
    2. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
    3. Tighten tensioner locking bolt and pivot bolt to 28 Nm (250 in. lbs.) (Fig. 2).
    4. Install generator/power steering belt.

    NOTE: A "used belt" is considered having more than 500 miles of service use. NOTE: Perform steps 1-7 to change the tensioner spring from the NEW belt position, to the USED belt position.
    1. Insert a 1/2" drive breaker bar into the square opening on tensioner. Hold counterclockwise pressure on tensioner, while removing tensioner locking bolt (Fig. 2).
    2. Carefully release the tension of spring on tensioner.
    3. Remove pivot bolt, tensioner, and spring from front cover.
    4. Insert spring into the USED belt position on tensioner bracket (Fig. 4).
    5. Install spring, tensioner bracket, and pivot bolt.
    6. Install pivot bolt. Tighten only finger tight, at this time.
    7. Using a 1/2" drive breaker bar, apply counterclockwise pressure until locking bolt can be installed.
    8. Install the USED belt by rotating tensioner counterclockwise until belt can be installed on pulleys. See (Fig. 5) for belt routing.
    9. Release tensioner and remove breaker bar. Belt is automatically adjusted with the tensioner's torsion spring.
    10. Tighten tensioner locking bolt and pivot bolt to 28 Nm (250 in. lbs.) (Fig. 2).
    11. Install generator/power steering belt.

How to replace serpentine belt for 96 bonnville

This is a fairly straightforward mechanical procedure. If you will allow me to provide a little perspective first, just so we start on the same page.

Since you ask only for the procedure for replacement, I do not want to jump over the diagnostic element of this process. If you are holding a broken belt in your hand you can skip directly past this paragraph. The serpentine belt, referred to as the engine drivebelt does what fan belts did in the "old days". This belt is by the crankshaft and in turn spins the alternator, the water pump and the pump for the power steering and the air conditioner compressor. This belt is a wear item and should be examined once per year. The belt is smooth on one side and has ribs running long ways on the other side. Using a flashlight check for shiny areas, cracks of any kind or fluid on the belt. Any of these, change the belt.

Now we need to get our navigational landmarks in sync. The engine in most front-wheel drive vehicles is mounted transversely (sideways). So front and back of the engine become left (front of engine) and right (rear of engine). The drivebelt is on the front of the engine, so to your left as you raise the hood and peer inside.

There should be a drivebelt routing decal on the upper radiator panel (between the engine and the front of the car). I recommend at this point that you also take a few pictures of the drivebelt with your cell phone or digital camera. Detail its path around all accessory components. I know that this is belt and suspenders but it will help greatly with replacement. Now look for the belt tensioner under the power steering pump. The power steering pump is at 12:00 o'clock on the front of the engine. Read the sticker on the square power steering reservoir at the top front of the engine to ensure you are in the right place. The tensioner is the round pulley that looks like it it isn't attached to anything and therefore has no purpose. Put the appropriate wrench on the nut on the front of the tensioner and turn counterclockwise (push toward the back of the car). A long handled ratchet works best here since you will need to get some leverage to turn the tensioner. This will loosen tension on the belt. While holding the belt tensioner remove the belt from all of the pulleys and pull it out. When you release the belt tensioner, it will swing down out of the way. Now again rotate the belt tensioner and route the new belt onto the engine. This should do it. If you are going to be doing this intermediate level of repair and maintenance I recommend you get a hard-copy repair manual for your vehicle or subscribe to one of the many excellent repair on-line service. Good luck!
