Auto Parts / COMMON PROBLEMS FOUND IN
COOLING SYSTEMS
The following chart is a listing of the six most common problems seen in
today’s cooling systems. Along with each problem is a description of how it
occurs, how it affects your engine and most importantly, the cure.

✱ It should be noted that rust can appear even within a chemically protected system when
oil is present in the coolant. If you do notice the presence of rust, the oil cooler should be
inspected for possible leaks.
