K100 16 valve engine. What is head stud tension in Nm?

when torquing down a head , modern figures in angles of rotaton
the initial tension is in nm to ensure that every stud is even then an angle meter is placed on the stud and the head is turned the set degrees ( in this case 90 degrees)
With tension wrenches there is a great variation in actual tension of the bolts and the angle method is more accurate

con rod bolt tension is 55-60ft/lbs
crank shaft main bearings is 80-85 ft/lbs
fly wheel bolts95-100 ft/lbs
crank shaft pulley nut 94-123 ft/lb
head studs tension 80-95 ft/lbs working in a spiral direction from no 1 stud directly in the centre of the head. Pull down in 10ft/lb increment starting at 20 ft/lbs
valve clearance is .010" both valves cold but after warming engine and re-tensioning the head studs re set valves to .012 both valves
injector retaining nuts tension12-17 ft/lbs

Hi, the first thing you will need to do is disconnect the battery cable. then take a wrench and release the tension on the serpentine belt by using the wrench to turn the tensioner to release the tension. From expirience i would draw a diagram of the belt routing before removing it. after the belt is removed you will need to remove the power wire from the back of the alternator by removing the nut that holds it on, then remove the connector from the side or back. there are three bolts holding the alternator to the engine. they should be a 15 mm or a 13 mm. assembly is reverse of removal. good luck

install:

1. The cylinder head should be cleaned and inspected prior to installation.

9. Apply a small amount of gasket sealant to the corners of the front camshaft caps and the top of the rear camshaft cover-to-cylinder head seal.
10. Install the valve cover using a new gasket
11. Align the timing marks on the camshaft gears.

15. Adjust the timing belt tension.
16. Install or connect the following:
    • Spark plug wires
    • Upper and lower timing belt coversCrankshaft pulley. Tighten the bolt to 70 ft. lbs. (95 Nm), plus an additional 30°, then another 15°.
