'04 Santa Fe Timing Belt Question

I bought the vehicle one year ago at 68k, it was a lease vehicle. It is now at 80,230 miles. It runs smooth, I take good care of it. I am aware the timing belt needs to be replaced at 60k. I do not know if it was done before I bought the vehicle, and I don't think I can pull any service records (tips to do so would be appreciated). It shifts smooth, it runs smooth.

What are the symptoms (if any) that the timing belt needs to be replaced? Will I feel anything? Smell anything? Will it drive different?

Also if I do go to check the timing belt, where can I open the timing belt cover and with what tools?

thanks!

EDIT into profile what vehicle you drive --> 2004 Santa Fe (2.4, 2.7 or 3.5,,, AWD or 2WD).... right now I be just guessing as to what you actually have.

<--- please fill in the 'location' and 'what you drive' boxes on your personal profile page.
This information makes it much easier for other members to answer/comment on your posts.

There will usually be no signs of failure......it will just fail. If you are not sure if it has been replaced then don't take a chance....replace it

Garage
Look on hmaservice.com for full instructions. Also if you are not mechanically inclined then i would take it to a garage as the job is pretty involved.

__________________________________
1. Remove the wheel of passenger side.
2. Remove the side cover.
3. Remove the engine cover.

4. Disconnect the powersteering hose fixing on the engine mounting bracket.

5. Remove the engine mounting bracket.

Before removing the engine mounting bracket support the engine oil pan with a jack or equivalent so as not to do down the engine.

6. Disconnect the connectors from the timing belt upper cover and remove the upper cover.
7. Remove the drive belt and loosen the 2 alternator mounting nuts (14 mm) and 2 bolts (12 mm) connecting the engine support bracket.
8. Loosen the 5 engine support bracket bolts.

To loosen the bolt shown in the forward of engine, first disconnect the alternator.

9. Remove the engine support bracket bolt by moving the engine up and down slightly and remove the bracket upward.
10. Remove the auto tensioner.

Rotate the crankshaft clockwise and align the timing mark to set the No.1 cylinder's piston to TDC (compression stroke).
At this time, the timing marks of the camshaft sprocket and cylinder head cover should coincide with each other.

11. Unbolt the tensioner to remove the timing belt.

If you plan to use the timing belt again, mark the rotation direction on the belt so you reinstall it correctly.

INSTALLATION
1. Install idler pulley to engine support lower bracket.

2. Install tensioner arm, shaft and plane washer to cylinder block.

--------------------------------------------------------------------------------

: 35 ~55 Nm (350 ~ 550 kg.cm)
--------------------------------------------------------------------------------

3. Install crankshaft sprocket and align the timing mark.

Be careful not to bend crankshaft sensing blade.

4. Install camshaft sprocket and adjust initial installation state as illustration.

5. Install auto tensioner to oil pump case.

If the auto tensioner rod is in its fully extended position, reset it as follows.

1. Clamp it in a vise equipped with soft jaws, in a level position. Use a plain washer if there is a pulg at the buttom of the auto tensioner.
2. Compress the rod slowly with the vose until the set hole in the rod is aligned with set hole in the cylinder.

3. Insert a set pin through the auto tensioner body and rod.

Leave the set pin installed in the auto tensioner.

6. Alighen the timing marks of each sprocket and install the timing belt in this order.
Crankshaft sprocket → Idler pulley → Exhaust camshaft sprocket (LH) → Intake camshaft sprocket (RH) → Exhaust camshaft sprocket (RH) → Tensioner pulley

• In this step, No. 1 is in TDC (Compression stroke)
• Do not insert fingers.

7. After installating the timing belt, reconfirm the timing mark.
8. Timing belt tension adjustment.
(1) Setting tension (under Non-operation of auto tensioner : set pin installed)
A. After turning the crankshaft 1/4 revolution connterclockwise, turn it clockwise to fit it in the position of No. 1 TDC.
Release the center bolt, and torque wrench as shown illustration and then tighten the center bolt by specified torque.
--------------------------------------------------------------------------------

Tension torque : 5Nm (50kg.cm, 3.7lb.ft)
--------------------------------------------------------------------------------

Be careful not to turn the tensioner pulley with the center bolt when tightening the center bolt.

--------------------------------------------------------------------------------

Tightening torque
Tensioner bolt : 43 ~ 55Nm (430 ~ 550kg.cm, 31 ~ 39lb.ft)
--------------------------------------------------------------------------------

(2) Tension checking set pin of auto tensioer.
A. Rotate the crankshaft 2 rotation clockwise and measure the projected load of auto tensioner in the TDC (#1 compression stroke) after 5 minutes.
B. Check the projected length is 3.8 ~ 4.5 mm.
C. Check again if the timing marks of each sprocket is with in specified position.

9. Install the engine support bracket.
10. Install the timing belt cover.
11. Install the alternator and drive belt.
12. Install the engine mounting bracket.
13. Install the side cover.
14. Install the wheel of passenger side.
INSPECTION
1. Inspect the belt closely. If the following problems are evident, replace the belt with a new one.
(1) Hardened back surface of rubber
Back surface is glossn, non-elastic and so hard that when the nail of your finger is pressed into it, no mark is produced.

(2) Cracked back surface of rubber.

(3) Side of belt is badly worn.

A belt in good condition should have clear-cut sides as if it were cut with a sharp knife.

(4) Teeth are badly worn out.
(5) Missing tooth

2. If backlash or an irregular noise is observed when rotating the pulley, replace the timing belt tensioner and idler pulley.
