You are so correct! Complexity and additional points of failure.

An important fact to keep in mind:  When one adds an improvement of any
kind such as aftermarket coolers, gauges, etc.   you must be aware that
while you are aiming for greater reliability you are also adding complexity
to your vehicle... so very careful thinking and execution is called for.
As Mark.mentions, problems are often caused by so called improvements that
are poorly done.
