Need torque for a 2000 Toyota Celicia GT 1.8L


Crank Main caps Tightening Torque

For the 12 Pointed Head Bearing Cap Sub-Assembly Bolts
Start from center bolts and tighten in a clockwise rotation working out
Step 1 all bolts 22 Nm or 16 ft lb
Step 2 all bolts 44 Nm or 32 ft lb
Step 3 all bolts 45 degrees additional clockwise rotation using an angle indicator.
Step 4 all bolts 45 degrees additional clockwise rotation using an angle indicator.

Hexagon Head Bearing Cap Sub-Assembly Bolts
1ZZ-FE Engine 18.5 Nm (14 ft.lb)
2ZZ-GE Engine 18 Nm (13 ft.lb)

Connecting rod:
1. Apply a light coat of engine oil on the threads and under the heads of the connecting rod cap bolts.
2. Install and alternately tighten the 2 connecting rod cap bolts in several passes. Torque: 1ZZ-FE: 20 Nm (204 kgf-cm, 15 ft. lbs.) 2ZZ-GE: 30 Nm (306 kgf-cm, 22 ft. lbs.) If any of the connecting rod cap bolts does not meet the torque specification, replace the connecting rod cap bolts.
3. Retighten the cap bolts by 90° more
4. Check that the crankshaft turns smoothly.

Replacing head


There should be 10 headbolts. This vehicle uses torque to yield headbolts and should be replaced with the new gasket. Bolts 1-8 get torqued to 40 ft lbs initially, bolts 9 and 10 get torqued to 30 ft lbs initially, Then all bolts get turned an additional 90 degrees. I would strongly suggest borrowing a torque angle gauge for doing this or you might be doing the same repair next week.
