What item is used to cool the engine in a car?

The radiator transfers the heat from the fluid inside to the air outside, thereby cooling the fluid, which in turn cools the engine. Radiators are also often used to cool automatic transmission fluids, air conditioner refrigerant, intake air, and sometimes to cool motor oil or power steering fluid. Click to see full answer Is an…

Can an overheated engine be fixed?

If you continue to drive an overheated car, you run the risk of warping your cylinder heads. This result is decreased power, misfiring, and excessive oil burning. However, cylinder heads aren't the only things in your engine that can melt; other components like sensors, belts, and wiring are also at risk. Click to see full…

What is AC thermodynamics?

Of note, AC (Alternating Current) is often used to describe someone who is homosexual. It derives from the use of AC/DC as a term for bi-sexual (the inference being that someone who is DC (Direct Current) is straight). Click to see full answer What is AC and DC? Electric current flows in two ways as…
