SOURCE: 87 samurai bolt torque specs for engine

The haynes book is not recommended since there are numerous mistakes and they still will not update. One of the biggest is the firing order.

The factory service manual is the only way to go.

Head bolts - 46 - 50.5 lbs (there is an order sequence for the bolts)

Intake & exhuast manifolds- 13.5 - 20 lbs

Flywheel - 41.5 - 47 lbs

Clutch cover - 13.5 - 20 lbs

I need too know the torque specs on head bolts and crankcam 2.4 engine


on a 2002 2.4 engine head bolts are 'torqued to distance'.

First, install all the bolts, and, in a sequential fashion, starting at the innermost, working outward, torque all bolts to 70 N-m/806 kgf-cm/58 foot lbs.

Next, mark the front side of each head bolt with a dot of paint. Retighten the cylinder head bolts 90 degrees, starting at the inner 2, and working outward.I dont thin anything has changed on this engine since then.

I need the torque specs and sequence on a 1998 chevy 350 vortec


Vortecs are a little different that old school small blocks, grab a Haynes or Chiltons, the cross patterns and specs are simply diagramed. Vortec, as any really, start with 25# then 45# and then final torque which I believe is around 70-75# but to be sure verify with the manual. AutoZones, Murry's, Adavance auto all carry the books, Cheap insurance.

Head tourque specs


The Haynes manual says for 96 - 98 to torque the head bolts to 22 ft lbs and than the short bolts 45 degrees, medium 55 and long 65 degrees

Those bolts are "Torque To Yield" bolts. You should be using new head bolts, tighten them to the spec listed and then rotate them the additional degrees of rotation that is specified. This assures that the bolts are tightened to a maximum clamp load.

To start out with, be sure to torque from the center out and there is a designated sequence to go in
