Engine cooling system
Overheating the engine can cause serious engine damage. To avoid the overheating the engine check the coolant level periodically. It should be at least at the "Min" mark in the coolant reservoir. If it's lower, add the coolant bringing the level to the "max" mark.
Caution: Never open the radiator or the coolant overflow reservoir when the engine is hot!
If you notice a coolant leak, have it fixed as soon as possible, as once the engine will be low on coolant it may overheat. If the engine temperature starts rising above normal, have your engine inspected before this can cause serious problems.
Check the front of the radiator - sometimes it may be obstructed with a debris; it's one of the possible reasons for overheating. Look at the image, this Buick' radiator is clogged. Avoid using a front end cover, as it can cause restrictions to the air flow through the radiator.

Why regular oil changes are so important?
Why regular oil changes are so important? What will happen if I miss my oil change?
Engine oil has limited life - after a certain point it starts losing lubricating qualities and carbonizes. Once it happens, the engine gets contaminated with carbon deposits or sludge (see the photo) that significantly shorten engine's life. When you change oil at or before manufacturer suggested interval, you change the oil before this "carbonizing" point, engine remains clean and once refilled with new oil ready to work hard again. If the engine oil has not been changed for long, carbon deposits start clogging the oil pick-up screen decreasing oil supply and increasing friction. Through the engine ventilation system the same carbon deposits build up inside the throttle body and EGR system causing rough idle and possible check engine light. Compression decreases and engine start wearing much faster.
