The main job of an expansion tank has to do with, not surprisingly, expansion. As a basic requirement, expansion tanks should allow enough space for coolant to expand at normal operating temperature and not be pushed out of the pressure relief fitting in the neck.
Cooling systems are one of the most important systems in an engine. Running an engine too hot can cause fluids and parts to break down an can ultimately lead to a catastrophic failure. At the same time an engine that is running too cold can be inefficient and poor performing.
There are two ways that engines have traditionally been cooled, by air and by water. Many old cars and even some newer motorcycles feature air cooled engines. However, most modern cars require liquid cooled systems.
As with installing anything the Accusump has a list of Do and Do Nots when installing. These unfortunately are common mistakes we see despite warnings in our full product installation guide. To save you the time we have listed a few of the common mistakes we see along with the correct way.
