Most of the areas inside the cylinder head that are not of structural significance are filled with a coolant passage. Honda blocks use aluminum, open-deck construction with iron sleeve inserts as friction surfaces. Metal surface temperatures in the cylinder head and combustion chamber can rise higher than 500 degrees F, so the cooling of these surfaces becomes a vital engine-design element for power and longevity. If an engine ran without coolant, even for a brief period, the temperatures could soar high enough to melt a piston and fuse it to the cylinder wall. So learn well, grasshopper, and dont forget to flush.

Understanding how the cooling system works, how to improve it, and how to identify possible problems can save you from making potentially wallet-devastating mistakes as well as help you to maximize performance.

Knowledge, in this instance, is your best defense. In these instances, a stock cooling system may not be able to handle the extra load. Sure, they rate low on the scale of sexiness, especially when compared to the likes of turbocharging but remember: Engines tweaked to rev higher or handle forced induction to create more power also create additional heat as a byproduct. Yet important as they are, cooling systems have a tendency to get overlooked. This absorption of heat is vital to proper engine performance. The remaining 70 percent of the fuels potential energy escapes through the tailpipe or is converted into heat thats absorbed by the cooling system. At peak efficiency, only about 30 percent of your fuels energy is used to create reciprocating power. The modified engine under your fauxcarbon-fiber hood is an air pump that uses a spark to release the potential energy of gasoline. Nice work, sportthis completely unnecessary trip may have just cost you your motor.

No one noticed the temperature needle peg itself deep into the doom zone. As the car inches up a congested interchange ramp, the engine begins to run a little roughthen a thin plume of steam rises from under the corner of the hood. Two hours later, the tiny coupe crawls along a clogged freeway, enjoying the inti-macy of Friday-night traffic. The turbocharged B18 and an engine-management system were completely justifiable expenses in your quest to be the toast of the show-car scene.

After all, youve spent the past year squeezing your parents credit cards for those mods to your Integra. Such mindless activity arouses the proposal of a road trip and, three pairs of eyes fixate on you for silent nomination as the driver. Its Friday afternoon.and you and your jobless friends are bored.
