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 supplemental 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 Kit 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 desirable 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 occurring.  This kit is a must for every truck. 
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. The lack of flow into the expansion tank is an indication that your filter is plugged. Change the filter if it should plug before the 3-month interval.  After the 4th filter is installed your filter should be changed once per year.

 If you have this style radiator our kit WILL NOT work for your truck.


Question: I have a 1994-1995 model year truck. What are the special concerns with this?

Answer: In 1994, Ford was transitioning from the IDI to the PSD. In the OE world "sweeping up the floor" is a term used for using up left over parts if not critical to operation before fully transitioning over to the new parts. Many of these trucks have IDI cooling systems. If your radiator cap is on the steel radiator and not on the expansion bottle, you have an IDI radiator. You can use the kit, but the return must be relocated from the instructions. You need to return the coolant from the filter to the heater hose that goes to the top of the water pump. This will require a 5/8" x 3/8" x 5/8" tee from an auto parts store. We can help you with one from our store if you'd like as well.
