B. REPAIR PROCEDURE2003 - 2008 MAZDA6 3.0L:
2006 TRIBUTE 3.0L - (built AFTER Jan. 17, 2006):
2008 TRIBUTE 3.0L - (with engine build date BEFORE May 16, 2007):
CAUTION:
Before attempting a 2006 Tribute repair, confirm if water pump pulley is driven by INTAKE or EXHAUST camshaft. Be sure to use correct repair procedure. The water pump on 2006 Tribute vehicles built AFTER Jan. 17, 2006 are driven by the "EXHAUST" camshaft pulley.
1. Verify the water pump is driven by the EXHAUST camshaft pulley.
2. Turn engine ON.
3. Verify the concern by use a stethoscope and conventional diagnostics to isolate the sound. If the noise comes from the LH valve cover area near cylinder # 6, proceed to Step 4.
4. Turn engine OFF.
5. Remove the LH valve cover according to applicable Workshop Manual.
6. Rotate the engine clockwise until cylinder # 6 EXHAUST cam lobes are pointing up (valves are fully CLOSED).
7. Remove all EXHAUST camshaft caps (do not remove INTAKE camshaft caps).
NOTE:
The camshaft caps must be completely lifted off, then set back into position. Loosening and retorquing cap bolts is not sufficient.
8. Reinstall all camshaft caps and torque bolts (except cam cap number 4L) in the sequence shown above to 8 Nm (72 lb-in).
9. Using a screwdriver positioned on each side of the top of cam cap number 4L, apply hand pressure and shift the cam cap toward the EXHAUST side of the cylinder head.
10. While holding cam cap number 4L in the shifted position, torque fasteners number 9 (inboard) first, to 8 Nm (72 lb-in), then torque fastener number 10.
11. Reinstall LH valve cover.
12. Verify repair.
