Product Description

Coolant filters are not a new idea to the diesel engine world. They come in most OEM applications for medium duty and OTR tractor trailer rigs. The idea was somehow tossed aside for light duty applications, most likely due to cost. For our light duty trucks it is a very important issue that needed to be addressed. Many diesel engines - like the Powerstroke - are cast with sand in the process. This sand is NOT completely removed from the system. In fact, much of this sand leaches out of the casting over time. The sand wears away at water pump seals, hoses and radiators. Removal of this sand can greatly increase your water pump life.
In addition to sand, there are other things that the filter is removing. SCAs, or supplimental coolant additives used in protecting against cavitation, often flake off the walls. This "precipitate" is a very abrasive particle - like a scale - floating around freely in the system unless caught by a filter.
The DIESELSITE Coolant Filter Install system will remove the loose particles in your cooling system and give your water pumps, radiators, water necks and radiator hoses the protection they need from these abrasive materials.  Wear is virtually eliminated by the removal of undesirable elements in your system. The desireable elements, like the actual chemical used in the SCA is not removed. 
The DIESELSITE Coolant Filter Kit is a bypass-style system that filters a small amount of the coolant on each pass.  By using a spin on filter we make it easy for you to change your coolant filter at regular intervals.  These filters will remove all solid particles -- new or old.  It is never too late to install a coolant filter in order to extend the longevity of your cooling system components.  While you cannot reverse the damage that is already done, you can eliminate further damage from occuring.  This kit is a must for every truck. 
In the past 9 years of doing business, we have seen a pattern of water pump failure. If you are one of the unlucky owners who have lost your pump between 40,000 and 80,000 miles it isn't too late to protect your new pump.  While some damage to your pump may already be done, a coolant filter install kit will extend the longevity of your pump before it fails.  AND, it will definitely insure that your next water pump will last much longer than your first one did.
The DIESELSITE Coolant Filter Install Kit includes all fittings, hose and stainless steel clamps needed for installation.

Recommendations on filter changes:
Use one filter every three months for the first nine months after installation. After the 4th filter is installed your filter should be changed once per year.




Question:Will a coolant filter rob coolant flow and cause overheating problems?

Answer: No. 
The DIESELSITE Coolant Filter Kit is routed in parallel with the current flow of your coolant system.  The majority of the coolant on each pass takes its normal path. Only a very small amount of coolant that would have travelled through the upper radiator hose is "bypassed" from the system to run through the new spin on coolant filter. So, your coolant follows its normal path while that small amount pulled off by our unit is directed through the new spin on filter.   That small amount, therefore, has actually bypassed the radiator. However, the filter itself acts as a radiator - heat exchanger - for the small amount of fluid pulled from the system into the filter so no amount of cooling has been lost in the process.  As this small amount of bypassed fluid leaves the coolant filter, it enters the heater hose return line which eventually makes it way into the lower radiator hose and resumes its original path. The continual movement of the coolant through the system will eventually insure that the entire system is filtered clean.

Question:What happens if the coolant filter is plugged and I don't catch it before it stops flowing?

Answer: You would no longer have an effective coolant filter in the system. That is ALL that would happen. Your coolant filter is a "bypass" in your system. Should the flow of this bypass be stopped -- by either an inline shut off valve or a plugged filter -- your coolant would follow its original path through the upper radiator(heater) hose as it did before the coolant filter was installed. No harm would be done.

Question:How do you know if the filter is working or needs to be changed?

Answer: You can feel for heat in the filter. If it feels cooler than it normally is, then a good chance it's dirty. As flow slows down through the filter, the temperature in the filter drops. A clogged filter will be approximately the same temperature as ambient.
Question:How much coolant will I lose if all I do at this time is add your Coolant Filter Install Kit?

Answer:  There is almost no fluid loss when installing this kit.  
Question:Where does the system mount?

Answer:  We have chosen to use existing bolts from the TPS body on the drivers side of the motor.  However, if you have a preferred location you wish to mount the filter head then you can do so.










Hey, guys and or gals!  

Just wanted to drop you a quick note here.  I purchased your dieselsite transmission filter kit with pressure gauge for my 02 diesel excursion.  I had to share this with you.  I installed your kit when my truck had 30K on it.  I had already done the initial tranny service right when I bought it, and converted to using Mobil syn atf fluid.  After reading about your product I decided to purchase the filter kit.  Well after driving a 100,000 miles.  It was time to drop the pan and change the internal filter.   To my shocked surprise the pan was just as clean as if I just serviced it yesterday!   And when I pulled the oem tranny filter out, I could not believe it.  The filter was not even dirty.  Amazing even after 100K of driving.  And there was zero debris in my pan. And the transmission shifts just as g ood now with 131,xxx as it did when I bought it.    

Im just stunned, that that little spin on filter is doing that good of a job.  You guys should be selling these to Ford.   

I also, purchased the coolant filter kit from you as well.  That one I was always leery about. But I read on several diesel post board about a coolant filter. And figured ah, what the heck, better have one.  Seeing the rate of water pumps going out.  But the curious george in me, decided to cut a old filter open.  Man you guys were spot on.  I could not believe the junk that was in there.  That's crazy.  So, for sure as you showed in the picture and your information was accurate 100%.  

 A happy customer !
