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

SOURCE: my 1999 gmc savana van turns over but does not

could be a bad fuel pump, or fuel pump relay. they are having problems(a lot) with the ethanol in the gas on GM products.Fuel pumps sales are through the roof at parts house on GM's. Have a pressure check on your fuel system. That is probably it. Add a can of Seafoam to your fuel every 3000 miles to alleviate this problem.

1990 7.3 idi auto non turbo fly wheel removal a replacement


An automatic doesn't have a flywheel, it has a flex plate instead. The torque converter makes it act a lot like a flywheel, though.

But... you're probably talking about the flex plate or the ring gear around its edge. This is going to require removing the engine from the vehicle - there's no other possible way to get the flex plate out.

Once the engine is sitting on the shop floor, it's a simple job to replace the flex plate - first you unbolt the torque converter and set it aside, then you unbolt the flex plate from the crankshaft. Bolt the new flex plate onto the crankshaft, bolt the torque converter to the new flex plate, and put the engine back into the vehicle.
