| General Filter Facts - Coolant Filters |
| Keeping the coolant contaminant-free
is critical to maintaining proper diesel engine temperature.
NAPA Filters has applied years of research and development
in filter media technology to create the industry's highest
performing coolant filters. Use our Filter
Look-up feature or consult your NAPA Filters Distributor,
to find the best NAPA Filters filter for your needs. |
| What
the Coolant Filter Does... |
Coolant filters are used on most
types of diesel engines. These filters help to maintain
proper engine heat transfer by filtering solid contaminants
from the coolant and by minimizing corrosion and deposits
in the cooling system.
| Properly
installed and maintained, coolant filters help
to provide: |
 |
A clean, well-functioning
engine cooling system. |
|
Proper engine heat dissipation. |
|
Engine efficiency through
improved heat conductivity. |
|
Method to introduce necessary
Supplemental Coolant Additives (SCA's) when required. |
Coolant filters mechanically filter
the coolant through a fine media, removing impurities
such as sand and rust particles suspended in the cooling
system. The coolant filter also conditions the coolant
by softening the water to minimize scale deposits, maintains
a neutral to slightly alkaline condition in the coolant,
and prevents rust.
Corrosion
Inhibitors
In some applications, a corrosion
inhibitor (SCA) is placed in the coolant filter. This
inhibitor dissolves into the coolant, forming a protective
film on all metal surfaces in the cooling system. The
inhibitor is a combination of chemical compounds blended
to provide corrosion and cavitation erosion protection,
pH control and water softening. |
