Motor oil is your vehicle's third cooling system

With summer approaching, AAA reminds motorists that low oil levels contribute to the engine overheating that occurs in millions of vehicles each summer.

According to John Nielsen, director of AAA's nationwide Approved Auto Repair network, When it comes to a vehicle's cooling systems, most people know about the air-conditioning system and the engine cooling system of water pump, radiator and liquid coolant. But many motorists might be surprised to learn oil also plays an important role in keeping vehicles cool. Heat that builds up in moving parts is reduced as oil circulates through the engine. The air passing under the vehicle as it is driven cools the oil in its pan before re-circulation, he said.

But the lower the level of oil, the hotter and harder the remaining oil has to work. Keeping the level at the "full" mark ensures proper lubrication and contributes to engine cooling, Nielsen says.
