An automotive cooling system protects an engine from catastrophic failure (e.g., blown head gaskets, and warped or cracked cylinder heads or cylinder blocks ) due to overheating. Basically, it consists of the following:
A series of galleries cast into the engine block and cylinder head, surrounding the combustion chambers with circulating coolant to carry away heat.
A mixture of water and antifreeze in proportions appropriate to the climate. Antifreeze itself is usually ethylene glycol or...
Brake rotors come in many different types. Before you can purchase a fresh set of brake rotors, you should understand each of these different types, what sets them apart, and what are the pros and cons of every style. The four kinds of brake rotors are:

Air conditioning was first offered by Packard, in 1939, in its production cars. These units were manufactured by Bishop and Babcock Co, of Cleveland, OH. Cars ordered with the new "Weather Conditioner" were shipped from Packard's East Grand Boulevard facility to the B&B factory where the conversion was performed. Once complete, the car was shipped to a local dealer where the customer would take delivery. Packard fully warranted and supported this conversion, and marketed it well. However,...
Pistons are one of the hardest working components of an internal combustion engine, where temperatures inside cylinders can reach over 1,800 degrees F. Early pistons were of cast iron, but there were obvious benefits for engine balancing if a lighter alloy could be used. To produce pistons that could survive engine combustion temperatures, it was necessary to develop new alloys such as Y alloy and hiduminium (high-strength aluminum alloy), specifically for use as pistons. A few early gas...
