Many of the expensive vehicle repairs that are often needed could be avoided if the car fluids had been checked regularly, Probably more people would understand the need for routine auto service if the reasons for checking the vital fluids were understood.
The main purpose of engine oil is to lubricate, but it also plays a big part in cooling as well. Engine components are really large blocks of metal moving against each other at high speed. If say an engine is running at 3000 rpm (revolutions per minute), then in a four cylinder engine the pistons are moving up and down at an incredible rate, as there are a number of different engine strokes as part of the cycle – induction, compression, expansion and exhaust all need the piston to move up and down the cylinder.
To keep compression high enough, the each piston is fitted with a metal ring to ensure a pressure tight seal. Engine oil lubrication is vital to keep the metal surfaces from seizing up with friction. There are many additional engine components which need to be kept lubricated such as the main engine bearings on the crankshaft, camshaft and valves. Finally engine oil circulating helps distribute the heat of combustion away from the cylinders. If the engine oil level is not checked, and it drops, then friction can cause severe engine wear very rapidly leading to a seized engine, which would need a major re-build.

Internal combustion engines have been around since the mid 1800’s, and have not fundamentally changed since that time. Burning fuel to cause an explosion to push down a piston in a cylinder is actually a very inefficient way of powering an engine, and up to 30% of all heat generated by the combustion is wasted. In fact a large part of engine components are dedicated to removing heat and sending it out into the atmosphere. Concentrated engine coolant (sometimes known as antifreeze) is mixed with water to help cool the engine block, with the use of pipes, radiator and electric fans.
The engine block itself has a number of hollow parts which are separate from the gasoline parts and surround the cylinders. Coolant is circulated around the block and into a radiator where heat is exchanged to the exterior of the vehicle. This coolant is driven by a water pump, which is mounted on the engine block and driven directly from the rotation of the crankshaft usually by a drive belt. Normally water will boil at a relatively low temperature, which would not be helpful for cooling, so the cooling system (when operating hot) is pressurized. Water at a high pressure boils at a higher temperature, especially when mixed with coolant, and that helps distribute more heat away from the engine block. Failure to regularly check the engine coolant can result in the engine not being cooled enough, and it can overheat leaving you stranded on the highway.
Transmission Fluid and More
Keep an eye on your transmission fluid, especially if you see any drops of red fluid underneath your vehicle, as this can be the first sign that a major transmission repair may be needed.
There are also a large number of other critical fluids that need checking on a regular schedule, including power steering fluid, hydraulic clutch fluid, and last but most importantly brake fluid.
