Evolution of the Automotive Radiator

From the time of the very first vehicles until the ’70s, radiators were made of a combination of brass and copper. No other material could compete with this combination in terms of heat dissipation, resistance to corrosion and ease of repair.

Consequences of Overheating

It is hard to disagree that one of the most destructive things a person can do to their vehicle is to allow the engine to overheat. Severe overheating can render the engine — and many of its component parts — completely useless, resulting in a large repair bill.

Heater Malfunctioning May Not Be a Cooling System Problem

Vehicle AC and heating systems have many common parts, which work synchronously to produce warm or cool air for the driver and passengers.

Many auto technicians identify the vehicle’s cooling system as the culprit; however, this may not always be the case.

Cold Weather Cooling System Protection

Flex Fans Versus Clutch Fans – Their Pros and Cons

Engine cooling fans are necessary to draw air through the radiator while the vehicle is moving at a slow speed or when at an idle. When the vehicle is moving at sufficient speed, air is being forced through the radiator at greater cubic feet per minute (CFM) than the fan is capable of, making the fan redundant.

How to Check for Leaks in an Automotive Cooling System

Cooling system leaks can be internal or external in nature. Either one is cause for concern and immediate attention to head off any possibility of overheating or catastrophic engine failure.
