First test of an engine is the compression test. If the compression is within 75% of the new engine spec, all cylinders should be within 20 psi of each other.
Next test is the cylinder leakdown test. Putting pressure into each cylinder and checking the leakage past the rings and valves.
General rule of thumb of any engine- if it starts up on the first 2 or 3 revolutions, does not emit blue smoke from the tailpipe and will pull the vehicle up a hill at normal speed, then it should be a good engine.

If your vehicle has an engine oil cooler ther will be two hydraulic lines going to each side of your radiator. If there are only lines going to one side of your radiator, then it doesn't have an engine oil cooler.
You Don't - It just breaks and blows the engine
Yes it can! How much work I do not know. I saw an 80 a few years back with a 125 engine in it. I just got cr80 and I'm going to put a 125 engine in it, just to play with people at the track. I'll let you know how hard it is.
You will not know. It may look great and be ready to snap. That is why you are required to replace the belt at a set mileage. If the engine is an interference engine and the belt breaks you will be more than just stranded with a non-running engine. You will have major internal engine damage. Replace the belt at the interval that is listed in your owners manual and do not neglect this maintenance.
