Question about 2001 Hyundai Sonata

1 Answer

Can an Alternator Belt installation cause a timing belt problem?


My wife's 2001 sonata (96,000km) broke its alternator belt while driving to work. I picked up the car and drove it to the nearest garage (not a hyundai dealership). When they replaced the alternator belt it was thrown off and then the timing belt failed - and did terrible internal damage. Ther cost of the repair is more than the value of the car. I called Hyundai to inquire about the amazing coincidence here. The head mechanic says that the garage should have checked for play in the crankshaft pulley before putting the alternator belt on and this could have caused the timing belt to jump. However the Hyundai Service Manager says this could not happen..... So is there any relationship between an improper alternator belt installation and the jumped timing belt...or was it just my very bad luck and timing?? Is there anything else that I should know.....my great car is now worthless...

    Yeh...that's what I'm wondering..did something get messed-up.....just seems strange that while the car was still on the ramp..the timing belt failed....!! I know the life expectancy of the belt is about 100K...but it literally popped when they started the car right after installing the alternator belt.

  • dstaubit Oct 22, 2008



    Hmmm....that's an interesting possibility..... does the cover interfere with the installation of the alternator belt....(ie. is it in the way - and would need to be pushed over??) It may be diffiult to tell from the cover now becuase it was removed to investigate the resultant damge.....

  • dstaubit Oct 22, 2008



    One more point - the Hyundai mechanic said excess play in the crank pulley could cause the timing belt to jump...it should be tightened first prior to the alternator belt being installed....any thoughts on that??

    my car actually died due to alternater belt coming off due to pulley being lose and key worked its way almost out could that cause timing to jump

  • Bill Boyd Feb 23, 2014

    The crank pulley for the timing belt has a small key to drive it and it is possible that if the crank pulley was loose enough to damage the alternator belt that the key became dislodged and allowed the timing pulley to slip on the shaft. IT requires a large tension on the crank pulley ( around 95 ft/lb ) and if that is not there then any thing can happen. Repairs to timing belt damage normally amounts to bent valves and a head shave to clean out any warpage. Normal practice in replacing a belt is to replace all the oil seals -hydraulic adjuster and idler pulleys . Normal cost around $1000 for the job so if you have been quoted more than that get more quotes

    if they were prying on cover and pushed cover into belt it seems like to much of a coincidence. While 90% percent of the time when a timing belt breaks or jumps it is when you first crank car. this is because of the initial strain on belt starter turns crank and belt turns cam. So it is like a **** on belt .Your engine is known as an interference engine which means damage can be done when breaks. I would look at area around crank pulley and see if you see belt cover cracked from prying on.

    if the pulley was loose yes that would allow gear to "walk" out and belt to slip off. but there would be no reason to loosen pulley to install belt. there would be know reason for cover to be messed with foer belt installation either. if you see the teeth on belt stripped then it was just time for belt to go this is usually what happens.will be a spot with about 10-15 teeth on timing belt with no teeth on it. if belt is shredded and broke then something caused this like cover pushed against it.

WHERE IS THE SERPENTINE BELT LOCATED ON A 2003 HYUNDAI SONATA


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.

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.

Hi and welcome to FixYa!

Looks like that you have an alternator belt issue. It was squeaking for the belt is loosen. I strongy suggest that you tighthen it for the alternator to charge the battery. If the alternator belt looks worn then replace it for optimum performance.

Hope this helps and thank you for using FixYa! Have a good one!

My Sonata GL is at 105K; in the maintenance schedule it is recommended to replace the timing belt. 1) If this particular belt breaks what would be the damage? 2) How much leeway do I have, eg.:100 miles,...


Timing belts are typically only used on overhead camshaft engines. Timing belts are used to synchronize the crankshaft with the camshaft, similar to a timing chain on an overhead valve (pushrod) engine. Unlike a timing belt, a timing chain will normally last the life of the engine without needing service or replacement. Timing belts use raised teeth to mesh with sprockets to operate the valvetrain of an overhead camshaft engine.

Whenever a vehicle with an unknown service history comes into your repair facility or is recently purchased, here are some points that should be asked to help prevent costly engine damage:

* Does the owner know if, or when the belt was replaced-
* If the vehicle purchased is used, or the condition and mileage of the last timing belt replacement are unknown, it is recommended to inspect, replace or at least inform the owner that the vehicle is equipped with a timing belt.
* Note the mileage of the vehicle. The average replacement interval for a timing belt is approximately 60,000 miles (96,000 km).


Inspection

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. All worn or damaged drive belts should be replaced immediately.

Removal & Installation

1. Raise and support the vehicle.
2. Remove the engine splash shield.
3. Rotate the drive belt tensioner clockwise to release the drive belt tension.
4. Remove the drive belt from the alternator.
5. Slowly release the drive belt tensioner.
6. Remove the drive belt from the accessory drive pulleys.

The belt is not adjusted correctly - that is assuming that the correct belt has been installed for your vehicle. If you'r esure it has, then the belt needs to be adjusted tighter onto the pulleys. It's not hard to do, and if your alternator wasn't tightened all the way, it may have loosened during driving. Have this checked and it should be fine. I've had this same thing happen a few times over my 46 years of life.

I have a 2001 nissan sentra and it needs a new alternator. i can't figure out how to get the last bolt out. do i have to remove the fan? also, i need pointers on getting the belt back on tightly. thanks....


  • Disconnect and label the wiring harness connections to the alternator (Painters Masking tape works very well for labeling Automotive wiring).
  • Loosen the alternator pivot bolt.
  • Remove the bolt that attaches the alternator to the adjustment arm.
  • Rotate the alternator to loosen the drive belt and disengage the belt from the pulley. Be careful that any spacers that are used in mounting are kept with their original bolts. This will make correct reinstallation much easier.
  • While supporting the alternator remove the pivot bolt.
  • Remove the alternator from the vehicle.
To reinstall the alternator, reverse the removal procedure.
To adjust the belt tension, leave the pivot and adjusting arms loose. Look up the belt tension specification for the vehicle you are working on. Using a belt tension gauge on the belt apply pressure to the alternator until the correct belt tension registers on the gauge and tighten the mounting and adjustment bolts to the specified torque specification.
CAUTION Over tightening of the alternator drive belt will cause the unit to whine and premature failure of the alternator drive end bearing, the water pump or the engine crankshaft.
