Do you understand that this system will not work on dual alternator equipped trucks?*
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.
We custom CNC machined a tee to tap into the heater line. Much smaller and compact. There is no extra weight hanging off the heater hose. This machined piece weighs only ounces. We also machined a tee to return the coolant to the resevoir tank. In addition to the machined fittings, a custom powdercoated mounting bracket has been designed specifically for EASY bolt in on the Duramax. All clamps used are 100% stainless steel, including the screw.
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.
HOW DOES IT WORK?
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 6 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, bracket, 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.
FREQUENTLY ASKED QUESTIONS:
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 heater core 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 heater core. As this small amount of bypassed fluid leaves the coolant filter, it enters the expansion tank which eventually makes it way into the lower radiator hose and back 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 heater core 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: One way to tell is by simply feeling the filter itself. When it starts feeling cooler than normal, it has stopped flowing. Another way is to install a clear sight glass in the outlet hose. This is done by using a simple glass fuel filter available at any auto parts store. Remove the filter inside the housing and splice into the line.
Question:What are the ball valves for?
Answer:The optional ball valves screw directly into the filter head assembly. They can be purchased separately below. They allow you to shut off the flow in both lines so filter changes are cleaner. The system can be under pressure and these allow changing the filter without getting sprayed with coolant. This means less coolant losses and less mess. The other benefit, rare as it is, if you find yourself without a replacement filter, the unit can be shut off and the truck can be run as usual with no change in coolant flow or loss of coolant.
