Air Cooled Engines
Engines that do not have a water cooling system can not use a heater core; one alternative is to guide air around the (very hot) engine exhaust manifold and then in to the vehicle's interior. Temperature control is achieved by mixing with unheated outside air. Air-cooled Volkswagen engines use this method. Depending on the design, this can cause a safety issue where a leak in the exhaust system will begin to fill the passenger cabin with deadly fumes.

Famous quotes containing the words air, cooled and/or engines:
“Nature is a setting that fits equally well a comic or a mourning piece. In good health, the air is a cordial of incredible virtue. Crossing a bare common, in snow puddles, at twilight, under a clouded sky, without having in my thoughts any occurrence of special good fortune, I have enjoyed a perfect exhilaration. I am glad to the brink of fear.”
—Ralph Waldo Emerson (1803–1882)
“He hath disgraced me, and hindered me half a million, laughed at my losses, mocked at my gains, scorned my nation, thwarted my bargains, cooled my friends, heated mine enemies; and what’s his reason? I am a Jew.”
—William Shakespeare (1564–1616)
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
