Timing belt replacement and crankshaft oil seal

I have taken my timing cover off my vehicle to check out the belt.
The belt looks pretty good to me considering the 147,000 miles it's got.
I'm a little puzzled on how this works considering the amount of tension and how you can calculate tension on the belt. I realize it has an idler and a tenitioner pulley. But I read somewhere you have to have like.30 downward tention on the belt. I don't get it?

Please try and explain. And the other issue is the water pump the housing looks new. And the belt says it's a Kia belt but surely this has been changed at some point. It would be nice if mechanics would put a date on the belt when changing. Anyway my other question of concern is where is the front crankshaft seal hidden? I'm going to replace everything being I have gone this far. Please explain the timing procedure and do I or do I not need to remove the two cam gears? Thanks, Jack

Welcome to 2CarPros.

The belt tension is measured by resistance. Basically, a scale is used to apply pressure on the belt and it must meet a prescribed tension before the belt move beyond a certain measurement.

Here are the directions for replacing the timing belt. The belt should be inspected every 60,000 miles and the recommended replacement is at 105 regardless of condition. The attached pictures correlate with these directions.

____________________________________________

REMOVAL
1. Disconnect the negative battery cable.
2. Remove the two fresh air duct mounting bolts on the radiator.
3. Loosen the fresh air duct clamp at the intake housing.
4. Remove the hose at the resonance chamber.

6. Remove the five cooling fan shroud bolts.
7. Remove the four thermo-modulated fan nuts.

9. Loosen the two generator mounting bolts (A and B).
10. Loosen the generator drive belt from the generator by loosening the adjusting bolt (c).
11. Remove the generator drive belt.
12. Remove the fan pulley.

14. Loosen the A/C idler pulley nut (A).
15. Remove the A/C drive belt by loosening the adjusting bolt.

Picture 7

16. Loosen the power steering pump lock bolt and mounting bolt.
17. Remove the power steering belt.
18. Remove five bolts and the upper timing belt cover.
19. Remove two bolts and the lower timing cover.

20. Loosen the tensioner lock bolt and pivot the tensioner pulley outward to remove the tension from the timing belt, then re-tighten the tensioner lock bolt.

Tightening Torque: 27 - 38 ft. Lbs. (37 - 52 Nm)

21. Mark the timing belt rotation for proper reinstallation if it is reused.

Picture 9

22. Remove the timing belt.

CAUTION: Be careful not to allow oil or grease on the belt.

INSTALLATION

Picture 10

1. Align the timing belt pulley and the pump body alignment marks.

Picture 11

2. Align the mating marks on the camshaft pulleys with the alignment marks on the seal plate.

NOTICE:
- For intake side camshaft pulley, align I mark.
- For exhaust side camshaft pulley, align E mark.

Picture 12

3. Install the timing belt so that there is no looseness at the tension side, and at the two camshaft pulleys.

CAUTION:
- If the timing belt is being reused, it must be reinstalled to rotate in the original direction.
- Check that there is no oil, grease, or dirt on the timing belt

4. Loosen the tensioner lock bolt.
5. Turn the crankshaft two complete revolutions in the direction of rotation.
6. Check that the mating marks are correctly aligned. If not aligned correctly, remove the timing belt and tensioner, and return to step 1.

Picture 13

7. Turn the crankshaft to align the S mark of the exhaust camshaft pulley with the seal plate mating mark.
8. Tighten the timing belt tensioner lock bolt.

Tightening torque: 27 - 38 ft. Lbs. (37 - 52 Nm, 3.8 - 5.3 kg-m)

Picture 14

9. Check the timing belt deflection. If the deflection is not correct, loosen the tensioner lock bolt and repeat steps 5-7 above. Replace the tensioner spring if necessary.

Belt deflection: 0.30 - 0.33 inch (7.5 - 8.5 mm)/22 lbs. (98 N, 10 kg)

1O. Install the lower timing belt cover and two bolts.

Tightening torque: 61 - 87 inch lbs. (7 - 10 Nm)

11. Install the upper timing belt cover and five bolts.

Tightening torque: 61 - 87 inch lbs. (7 - 10 Nm)

12. Install the power steering drive belt and set belt deflection.

Power Steering Belt deflection:
New: 0.31 - 0.39 inch (8 - 10 mm)
Used 0.35 - 0.43 inch (9 - 11 mm)

Picture 15

13. Tighten the lock bolt (A) and mounting bolt (B).

Tightening torque: 27 - 34 ft. Lbs. (37 - 46 Nm)

14. Install the fan pulley.
15. Install the generator drive belt and adjust belt deflection by tightening adjusting bolt (c).
