Cant find torque settings for a mazda XA 3.0L 4 cylider

Follow the link mazda b2500 torque sequence and settings cylinder head td bolts

Hi,

I've attached an image showing the torque settings for the major items. I hope this helps.

go to autozone.com and login or set up an account if you don't already have one it's free. Then you will be able to punch in the year make and model of your car and find repair manuals for any vehicle you desire. In your case 83 mazda 626. and go to cylinder head info and there you will find what your looking for. Good luck.

contact parts store or dealer service,

What year an what C.I.

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

Since you didn't say which engine you have, I've pulled torque specs for 3 different engines. Also, since I can't include a diagram showing the relative locations of the numbered head-bolt locations, it would be a good idea for you to purchase a vehicle specific repair guide that will show this info.

Take particular note about the TTY (Torque to Yield) bolts used on 2 of the 3 engines shown. It is said that new head bolts MUST BE USED when head is replaced or re-installed to obtain the proper torque.

B2500 4 Cylinder

Torque sequence: --------- ' 10 6 2 4 8 ' front ' ' ' 7 3 1 5 9 ' -----------Step 1: torque in sequence to 51 Ft/Lbs Step 2: torque again in sequence to 51 Ft/Lbs Step 3: final tighten all bolts an additional 90 to 100 degrees recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) that permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.

B3000 3.0 6 Cylinder

Torque sequence ---------- ' 6 4 2 8 ' ' ' ' 5 1 3 7 ' ---------- Step 1: torque to 59 Ft/Lbs Step 2: loosen in sequence (1) full turn Step 3: torque to 41 Ft/Lbs Step 4: torque to 73 Ft/Lbs

B4000 4.0 6 Cylinder

Torque sequence --------- ' 5 1 3 7 ' ' ' ' 6 4 2 8 ' --------- Step 1: torque cylinder head bolts in sequence to 26 Ft/Lbs Step 2: torque cylinder head bolts to 56 Ft/Lbs Step 3: turn cylinder head bolts in sequence an additional 90-degrees recheck final torque in sequence *** CAUTION ***engine uses Torque To Yield head bolts (TTY) that permanently stretch during the initial installation. New head bolts must be used when cylinder head is replaced or re-installed to obtain proper torque.

Good luck with this job!

Position the cylinder head on the cylinder block. Tighten the cylinder head bolts in 2 steps following the proper torque sequence. The first step is 37 ft. lbs. (50 Nm) and the second step is 68 ft. lbs. (92 Nm).
