19. Remove plug from exhaust camshaft sprocket 11.

20. Using a wrench on hexagon to hold camshafts 12, loosen camshaft sprocket retaining bolts 13 & 14.

Attention To Removal Step #20 is critical to proper installation!

21. Remove and discard timing belt.

NOTE: DO NOT reinstall used belt. Timing belt must always be renewed once it had been loosened or removed.

IMPORTANT: To maximize Timing Belt System performance...it is recommended that Timing Belt Tenionser(s) and Idler(s) be replaced at the same time as Timing Belts!

Installation:

NOTE: The lower guide pulley may not be fitted to some models a after 06/1999.

1. Ensure camshaft alignment tool installed correctly 7.

NOTE: Valves for No.4 cylinder should be on 'overlap' (camshaft lobes facing inward).

2. Temporarily install crankshaft pulley 3.

3. Check that the notch and pointer are alligned 2.

4. Remove plug from cylinder block 15 and install crankshaft timing pin 16

No.303-574 (T97P6000A).

5. Adjust position of crankshaft until it rest against timing pin.

6. Remove crankshaft pulley.

NOTE: Under normal circumstances, the variable valve timing system will not return to its original base position. Ensure adjustable exhaust camshaft sprocket is reset as follows:

Ensure camshaft alignment tool installed 7.

Lightly tighten the camshaft sprocket bolt 14, to prevent sprocket hub turning on camshaft.

Turn the exhaust camshaft sprocket by hand fully counterclockwise.

Loosen the camshaft sprocket bolt 14.

Ensure the sprocket moves freely on the camshaft.

Turn sprocket until hole and largelug of sprocket hub at top.

7. Type A:

Ensure the tensioner bracket is unhooked from metal clip 10 and is at the 4 o'clock position 17.

Align 6mm Allen wrench hole 18 with the 'U' shaped notch in the pointer 19.

8. Type B:

Ensure the tensioner bracket is unhooked from metal clip 10.

9. Install the new timing belt in a counterclockwise direction starting at the crankshaft sprocket, ensure timing belt taut between sprocets on non-tensioned side.

10. Ensure crankshaft remains resting against timing pin 16 during the tensioning procedure.

11. Type A:

Hook the tensioner bracket 17 into the metal clip 10.

Position the 6mm Allen wrench hole 18 at the 4 o'clock position. Finger tighten the tensioner bolt 8.

Turn the tensioner counterclockwise 20 until 'U' shaped notch in the pointer 19 aligned with mark on bracket 17.

Hold the tensioner pulley in position.

12 Type B:

Hook the tensioner bracket into the metal clip 10 and finger tighten the tensioner bolt 8.

Turn the tensioner counterclockwise 21 until the tip of the pointer 22 aligned with the mark 23.

Hold the tensioner pulley in position.

13. Torque the tensioner bolt 8 to 18.5 ft. lbs.

In the 1998 Mercury Mountaineer : The 4.0 liter SOHC - V6 engine has ( 3 ) timing CHAINS The 5.0 liter V8 engine has ( 1 ) timing CHAIN

Normally the timing chain will last the life of the engine and is not an item you replace. But on your Saturn it is critical that the oil/filter be changed exactly as listed in the owner's manual. The timing chain may also come into contact with the timing cover, causing noise in the engine. The only way to know for sure if the chain needs replacing is to look at it. If you do that, you might as well just replace it.
