4, one of them is the thrust bearing
They had a 2.5L 4 cylinder engine and a 3.5L 6 cylinder engine available.
There are two cylinder heads on a V6 3.1L engine.
I assume you mean to ask how difficult it is to change the main bearings WITHOUT pulling the engine out of the vehicle. Don't bother. To properly replace the main bearings you need to pull the crankshaft away from the engine far enough to be able to put a micrometer on the bearing surfaces of the crankshaft. To do that you need to disconnect the crankshaft from the transmission AND pull the pistons part way out. Also, depending on the type of seal used, many rear main seals must be replaced by pressing them into place after the crankshaft is in. Don't even try to replace bearings without first verifying the status of the crankshaft. It must be round and within tolerance. If the old bearings have worn there isn't much chance that the crankshaft hasn't been affected.
I am assuming you mean the engine: 2.4L 4 cylinder engine: 4.25qts 3.4L 6 cylinder engine: 4.5qts
It depends upon cylinder in car. 3 ignition coils - 3 cylinder engine. 4 ignition coils- 4 cylinder engine.
Parts of car that needs friction are many , some of them are listed below: 1. car and road-tires . 2. In different parts of car engine e.g: Cam lobes, cam followers, lifters, cam bearings, main bearings, rod bearings, cylinders and piston rings, cylinders and piston skirts.
This engine (allowing it is an automotive engine) is a four valve per cylinder engine.
1 cylinder at a time.
A normal combustion engine has one piston per cylinder. So a 4 cylinder has 4 pistons, a 8 cylinder has 8 pistons, etc.
2 on the 4 cylinder engine or 6 on the 6 cylinder engine.
