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.
These filter are being used on gas engines too.
I am also a member of the BITOG site and they are filter and Oil gurus.
I just wanted to post it ahead of time in case someone was thinking of a coolant filter setup.
This is a great site and I want to share what I have learned from them.
I will also have power steering filter (spin on also).Once I get the ball rolling with my installs, pics and writeup for you guys/gals they will be posted accordingly.
I am still debating using a motor Guard TP bypass filter setup for my tranny or using a Hydraulic Donaldson filter setup rated at 3um that I would probably never have to change.I have a Frantz TP Bypass setup lined up to be installed for my oil. I will keep my dual remote Perma Cool setup and run 2 Wix 51515 on it. My oil capacity should be just over 8 quarts with the dual remote and bypass filter. My electric fan install and Spal controller is also on the list. And I think finally is my Sunpro triple mechanical guages for my oil temp, pressure and electrical voltage. My scanguage will keep track of my coolant temp. The guages are installed and wired to the dimmer. the voltage gauge is only on working as i have not setup my bypass setup, that will allow for my pressure and temp readings. I have pics of the install and prep of my console for my gauges.
The warm weather and non busy weekends are the only time I can work on the truck. I get yelled at by the wife all the time about spending too much time messing with truck..LOL
I want to get all this done before my drive up to Niagra Falls this summer. I want a very road worthy machine for lots of road trips.
