DIESELSITE Coolant Filter Install Kit – Ford 7.3L Powerstroke

Protect Your Cooling System – Extend Water Pump & Radiator Life


NOTE: If you have a 1994–1995 model, see the FAQ section below for special installation considerations.

Coolant filtration is a proven solution in the heavy-duty diesel world — and it's just as critical for your 7.3L Powerstroke. Many diesel engines, including the 7.3L, are cast with sand, and not all of it is removed during manufacturing. Over time, this leftover sand leaches into the cooling system and causes premature wear to water pumps, hoses, and radiators.

The DIESELSITE Coolant Filter Kit captures abrasive materials like casting sand and precipitated SCAs (Supplemental Coolant Additives), helping prevent internal wear and extending the life of your water pump, radiator, oil cooler, and coolant lines.


Key Benefits:

  • Removes abrasive particles like sand and crystallized SCAs

  • Protects water pumps, hoses, radiators, and oil coolers

  • Prevents premature cooling system failure

  • Bypass-style filter — no flow restriction or overheating risk

  • Spin-on filter design for quick, easy replacement

  • Includes all fittings, hose, and stainless clamps

  • Virtually eliminates wear from coolant contaminants


🔧 How It Works:

This is a bypass-style system that filters a small amount of coolant at a time.
It’s routed in parallel with the factory cooling system, so it doesn’t affect coolant flow or cooling efficiency.
As the filter removes debris on each pass, your system is gradually cleaned of harmful particles.


🛠️ Installation & Maintenance:

  • Installs easily with basic tools

  • Includes custom instructions for minimal fluid loss

  • Initial Filter Change Schedule:

    • Replace every 3 months for the first 9 months

    • Then, replace once per year

  • You’ll know the filter is due when coolant flow into the overflow tank slows or stops


🧰 Kit Includes:

  • DIESELSITE coolant filter mount

  • High-quality hoses and stainless steel clamps

  • Brass fittings

  • Spin-on filter

  • Detailed installation instructions


⚠️ Special Note for 1994–1995 Trucks:

Some early 7.3L Powerstrokes came with IDI-style cooling systems (radiator cap on the radiator instead of the overflow tank). If your truck has this setup, you can still use this kit, but you’ll need to reroute the filter return line.

✅ You’ll need a 5/8" x 3/8" x 5/8" heater hose tee to connect the return line to the heater hose going to the top of the water pump.
We can supply this tee from our store — just ask!


💬 FAQs

Q: Will this restrict coolant flow or cause overheating?
A: No. The system is routed in parallel with the stock coolant path. Only a small amount is diverted through the filter, and the filter itself acts as a heat exchanger.

Q: What happens if the filter plugs up?
A: The system reverts to normal coolant flow. You simply lose filtration until the filter is replaced — no damage or flow restriction occurs.

Q: How do I know when to change the filter?
A: Watch the coolant return line into the expansion tank. If flow slows or stops, it’s time to change the filter.

Q: How much coolant will I lose during installation?
A: Very little. Our instructions walk you through how to avoid draining the system during install.


📸 Real-World Results:

  • Photo 1: Filter removed after 3 months after a full coolant flush — filled with sand and sediment.

  • Photo 2: 7.3L oil cooler clogged with debris — proof these particles wreak havoc on internal components.


🔩 Don’t wait for failure — protect your Powerstroke now.

Whether you’ve already replaced a water pump or are trying to make your current one last, it’s never too late to install a coolant filter. Give your cooling system the defense it needs with a proven, affordable solution.

Never Pay Again. Easy and affordable for your health and the vehicle.
Size: For Sonata Gas 2015-2019
Way easier to replace than I thought. I’ve done a cabin filter before, but never the engine air filter. After this, I’ll never pay someone to do it again. I actually went into a store first, and the cabin filter alone was the same price as this set that includes both the cabin and engine filters. Since I needed both, this was a no-brainer. Install was quick and straightforward, even for someone who’s not a "car guy". I can’t speak scientifically on how well they filter, but they’re definitely better than the mouse-destroyed ones that were in this car before. Huge improvement. Highly recommend if you’re looking to save money and do it yourself. They fit well and seemed to be exactly what was needed and expected.

Quality air filters

The Honda dealership quoted over $100 for parts alone. I purchased both filters for $25 and they where a perfect fit and easy to install without any tools.

4.5 2025 cx-50 : Cabin filter fit perfect. Engine filter was not as precise , it was a perfect edged rectangle whilst the new filter had round edges, it did fit after all. Way better than paying 100$+ at the dealer. I will come back once I notice any airflow changes & or smells .

Good Product, But Doesn't Fit All RAV4 Models
Size: For Avalon 19-22|Camry 18-24|19-25 RAV4/ES350, Size: For Avalon 19-22|Camry 18-24|19-25 RAV4/ES350
Both filters seemed to be of high quality, but the engine air filter did not fit in my 2019 RAV4 XSE Hybrid. Please note that ordering this was my mistake -- I didn't realize that the hybrid and gas-only filters were different sizes -- and that StaunchAuto also offers a hybrid version of the kit, which I have just ordered.

Good fit, good value
Style: CF12436 Classic, Style: CF12436 Classic
Purchased this filter for my 2023 Outback. First off changing the cabin filter on this model Subaru is amazingly easy and can be done with no tools and no more then 5 minutes. Pictures posted show packaging, the paper "Blue" filter side, the "Black" charcoal side and the foam outer edge. The filter is well made and is very sturdy as the outer shell is plastic vs. other paper filters that are more flexible. Holding the filter in your hand and giving it a slite shake you can hear the activated charcoal within it. After installing the filter I had a few trips in the car, did I notice any difference in the air quality coming into the cabin....... no. But does this mean its not working? also no. What I can say is the filter fit snug and left no gaps, and with the plastic surroundings and foam in sure the filter will not be letting anything get by as it passes through the system. All and all this filter is well made and sturdy, and seems to be a good value with other paper only filters being about the same price.
