A simple test for interfacial tension is to place a drop of used oil from the dipstick on the surface of water. If the oil drop spreads out over the water’s surface (instead of beading up like a new oil) it may be time for an oil change. Lesson No. 5 - Signs of Coolant Leak ...
Engine coolant not only cools the internal components of an engine but helps with the oil as well. Coolant passes from the water pump through the engine coolant passages in the block surrounding the cylinders and up through the cylinder heads. Oil to the valve train returns to the oil pan ...
With the engine cold, remove the oil fill cap to inspect for brown milky goo that has collected on the bottom of the cap, which is an indication that coolant is leaking into the oil. Chances are the head gasket has failed, but if theengine has been severely overheatedit could have a c...
Monitoring the condition of the oil allows you to optimize drain intervals, so you can maximize the fluid’s service life. Performing fewer oil changes minimizes maintenance costs and reduces downtime for businesses that depend on equipment and vehicle availability. It also reduces the amount of wa...
How much do you know about the oil drilling process? DCI Remember those orange juice commercials? The ones where people tried to poke a rolling orange with a straw? It's easy to think of the oil drilling process like that: Difficult to find the bullseye for the straw, but just a ma...
Here's something else that makes a do-it-yourself oil change take longer: disposing of the used oil. Just dumping it is not only bad for the environment, but also illegal. So, do-it-yourselfers need to collect the dirty, used oil and safely transport it to a recycling or disposal ...
Red or brown drops of oil in the coolant would be a symptom of such a leak. Because the oil cooler is inside the radiator, the radiator must be replaced to eliminate the problem. The transmission fluid should also be changed.PRESSURE TESTING THE COOLING SYSTEM FOR LEAKS...
The dashboard instrument cluster in your car organizes a variety of sensors and gauges, including the oil pressure gauge, coolant temperature gauge, fuel level gauge, tachometer and more. But the most prominent gauge— and perhaps the most important, at least in terms of how many times you lo...
overheating in A8. The head gasket is a crucial component that seals the gap between the engine block and the cylinder head, preventing the mixing of engine coolant, engine oil, and combustion gases. When a head gasket blows or fails, several problems can arise, leading to engine overheating...
It’s especially important to plan for a pre-winter oil change because oil gets thick and lazy in winter temperatures. Consider changing to “winter weight” oil if you live in a cold climate. Want to keep your oil warm in wintry climates? Consider purchasing anelectric blanket for your car...
