Not necessary.
Although not necessary, many machine shops use a drop on the main and rod caps as "insurance".
Since it doesn't harm anything and it MIGHT prevent a bearing cap from working loose, why not?
no
It is always a good idea to replace the head bolts with new ones and is cheap insurance.
The basic idea of a thread is to be able to program different things that will be executed simultaneously.
This is pretty simple-there is a yoke on either end of the drive shaft-one connects to the tranny and one to the rear end. Each one has four bolts. It's a good idea to put some heat to the bolts before trying to remove them, Ford put a thread locker on the bolts and you'll have a hard time turning them without heat. You need a twelve point 12 mm socket to fit the bolts....pretty quick and easy
A thread is an execution path through a program, initiated as an asychronous process. Killing a thread means to stop its execution. Usually, this is not a good idea. A thread should stop its own execution, either because it has completed its work, or because it was told to do so, perhaps with a shared semaphore. If you kill the thread externally, the thread stops and does not get a chance to clean things up, such as closing files and making objects consistent.
It is a good idea to replace them at the same time as your regular tune-up.
It's a good idea.
i have know idea
The starter is bolted to the engine by two bolts which makes it very easy to change, just remove the bolts and drop the starter down until you can remove the wires from it, it is a good idea to remove the negative battery cable before starting the job to prevent arcing the wires to ground.
Yes, a chevy dealership will usually have good deals and or warranties on the cars. Dealerships are almost always fam most casesily owned which is a plus in most cases.
the main purpose for lock bolts or lock nuts are so someone does no steal the wheels off the car they are not necessary but a good idea if you really like the wheels
If the engine is high mileage yes, replace the head bolts. If it is low mileage it is your choice, but is always a good idea to replace them.
