Choosing a cooling system Do you dread the thought of enduring another sweltering summer of sleepless nights? Can you no longer bear living in a hot box and want to install a cooling system but don’t know where to start? This brochure outlines various cooling options to help you choose the most effective system for your needs. If you [...]
evaporation cooling Evaporating water to reduce air temperature and increase air humidity. This process occurs when heat in the air is trans- ferred to the water, causing it to evaporate. Examples: •Sweating/Perspiring •“Swamp Coolers” •Outdoor Misters Download

Things You’ll Need: Engine Coolants Step1Add a mixture of one-half water and one-half antifreeze to the radiator. Fill it right up to the top. Step2Fill the overflow/coolant reservoir with the same 50/50 mixture. Step3Leave the radiator cap off, turn the engine on and let it run until the radiator “burps”: You will see the coolant level drop and [...]
The radiator cap actually increases the boiling point of your coolant by about 45 F (25 C). How does this simple cap do this? The same way a pressure cooker increases the boiling temperature of water. The cap is actually a pressure release valve, and on cars it is usually set to 15 psi. The [...]
A radiator is a type of heat exchanger. It is designed to transfer heat from the hot coolant that flows through it to the air blown through it by the fan. Most modern cars use aluminum radiators. These radiators are made by brazing thin aluminum fins to flattened aluminum tubes. The coolant flows from the [...]
Note that the walls of the cylinder are quite thin, and that the engine block is mostly hollow The engine block and cylinder head have many passageways cast or machined in them to allow for fluid flow. These passageways direct the coolant to the most critical areas of the engine. Temperatures in the combustion chamber of [...]
The water pump is a simple centrifugal pump driven by a belt connected to the crankshaft of the engine. The pump circulates fluid whenever the engine is running. A centrifugal pump like the one used in your car The water pump uses centrifugal force to send fluid to the outside while it spins, causing fluid to be [...]
