Sitting Engine

The engine is in the car, and is sealed.

Four Questions...

1. What size is the front crankshaft bolt of a Fiero V6?
1a. How much torque do you have to put on it to get it moving.
2. If the engine hasn't been running in 6 years (The car/engine spent 5 years inside, 1 year out) could turning the engine slightly over do any damage? Not even a full rotation, I just want to see if it's seized.
3. If it does turn over, would you recommend that I start it without tearing it apart?
4. If it doesn't turn over, what is an estimated cost for rebuilding it?

I say don't even bother with the hand crank. Unless it does not have a starter.

You can pull the coil wire and both the plugs going to the ignition module. (I remove the module wires just for the slight chance that the cranking will power up the module and damage pickup coil)

Check all the fluids, and hit the key, if it rotates without any bangs, hook up the ignition and light the fire so to speak.   

If its been sitting that long, before you put it into extended use, it will need a full tune up and oil change.


Oh pop the air filter out. In most cases it will be rusty and you don't want chunks flying into the intake.
