DIESELSITE 2008-2010 Ford 6.4L Coolant Filtration System F250/350/450
Billet Aluminum Housing
PLEASE NOTE: Shut off Valves are included in this system. 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.
Recommendations on filter changes:
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.
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.
Answer: You can monitor the flow in the return line by looking at the return flow into the expansion tank. Having someone rev the motor a bit makes it easier to see the flow or lack of flow. Another way is to feel how hot the filter is. When the filter is clean, and the engine is up to operating temperatures, the filter will be very hot as it will be the same temperature as the engine coolant. As the filter gets dirty, it will cause less flow to pass through the filter. When the filter is very dirty, or almost plugged, the filter will be significantly cooler than normal. And lastly, you can also install a sight glass (3/8" glass fuel filter available at any auto parts store) in the return line going from the filter to the expansion tank to see the actual flow.
Answer: There is almost no fluid loss when installing this kit.
Answer: We chose a location behind the front bumper (on the passenger side) for easy access. However, we supply enough hose and the instructions for connecting the system to your engine, that you can feel free to mount it in another location should something you've already added to your truck interferes.
