The fluid in the radiator need to be clean and clear in spite of generally getting green. What you do not choose to see is oil, debris or nothing. If you're comfortable working around cars and radiators you could start and run the auto together with the radiator cap off. When you have bubbles like a rolling boil once you rev up the engine then the car or truck likely has internal failure within the form of lost compression within the engine escaping by way of the normally isolated cooling method.
There will likely be a brake fluid reservoir mounted towards the firewall of the engine compartment.

Smoke in the tailpipe is going to be burning oil, burning coolant or unburnt gasoline in some circumstances. Coolant burns white and smells like burning maple syrup. Oil burns blue/white/grey and may also be visible coming in the engine oil dipstick when you remove the dipstick whilst the engine is running. The term for this really is "blow-by" which refers to engine oil blowing by piston rings which have come to be worn with age, heat and friction.
Finally one of the most vital thing to prevent is an engine using a knocking sound. A knock is identified to be the death march of an engine because it indicates a significant internal engine element failure. Steer clear of knocking engines altogether.
