Getting the most out of your performance parts comes down to the details. When faced with hard driving conditions, a vehicle's cooling system becomes highly pressurized. Factory caps are not equipped to handle long term use and often lose pressure, in turn reducing the potential coolant boiling point and boiling the coolant. The Mishimoto 1.1 Bar Overflow Reservoir Cap will keep coolant where it needs to be, flowing within the system.

Mishimoto Liquid Chill, the new performance radiator additive will help cool your car up to 30 degrees over regular coolant.Liquid Chill is non-corrosive and compatible with all coolant and/or water mixtures.Made in USA.

Liquid Chill Synthetic Engine Coolant technology combines an inherently nontoxic propylene glycol base with unique poly organic additives (POAT) to allow a service life that can exceed 7+ years or 750,000 miles in Heavy Duty (diesel) applications and over 2+ years or 250,000 miles in Light Duty (gasoline) applications, although Mishimoto engineers recommend consulting your service manual for application-specific guidelines. Liquid Chill Synthetic Engine Coolant is designed to meet or exceed all stock specifications and exceeds the specs needed to pass ASTM D6210 and ASTM D3306 coolant tests. It's premixed with deionized water, so it's ready to use and safe for all water-cooled engines, protecting against boilover to 265 degrees Fahrenheit and freezing to -26 degrees Fahrenheit (with 15 psi cap)**.

Do you hear that? That little sigh that's coming from your engine bay? That's your radiator asking for Mishimoto Liquid Chill Synthetic Engine Coolant. Formulated to operate flawlessly under extreme conditions and with both gasoline and diesel, Liquid Chill will help your engine warm up quickly and maintain ideal operating temperatures.

The proprietary formula doesn't contain any nasty nitrates, amines, high-fructose corn syrup, phosphates, silicates, borates, and all those other ates that will clog up thermostats and radiators, and cause excessive wear on water pumps. However, Mishimoto engineers strongly recommend that you and your children do NOT consume this coolant. Seriously, don't drink it, and keep it on a high shelf so kids and pets can't get to it. Now, by popular demand, we're offering Liquid Chill in convenient 64 oz. containers, so you can top your coolant off, quickly refill your dirtbike radiator, or just keep it around as a conversation piece.

It's been over a decade since the last 1999-2003 7.3L Powerstroke rolled off the assembly line. A lot can happen to a vehicle in that much time. And, if you're like many 7.3L Powerstroke owners, you've been through more than one degas tank.

Over time, the stock plastic tank becomes brittle and cloudy, making it prone to breaking and impossible to see the coolant level.

Luckily, Mishimoto has a solution that will look and function in 15 years, just as well as it does today. Replace your ugly and brittle plastic stock tank with Mishimoto's all-aluminum 1999-2003 7.3L Powerstroke degas tank.

The fully-welded design of Mishimoto's degas tank means that it won't crack and leak coolant, and the integrated sight glass makes checking the coolant level easy. No more trying to shine a flashlight through a muddy tank. For even more convenience, the Mishimoto degas tank includes an additional 1/8" NPT port for easy pressure monitoring. Of course, this degas tank is also backed by Mishimoto's Lifetime Warranty.

In the unlikely event you have an issue, Mishimoto has you, and your 1999-2003 Ford 7.3L Powerstroke, covered.

This Replacement Coolant Filter from CAT fits all Sinister Diesel Coolant Filtration Kits as well as all of our Bypass Oil/Coolant Filtration Kits and is available on many of them as an upgrade option.

These replacement coolant filters for diesel engines use the best quality materials to withstand whatever duty your truck sees. The advanced filtration in every CAT coolant filter removes contaminants like casting sand leftover from the manufacturing process, metal shavings, rust, and mineral deposits floating in your coolant that can diminish the heat capacity of your truck?s cooling system, lead to overheating, and even engine failure.

On new installations of a Sinister Diesel Coolant Filtration Kit, we recommend replacement of the first filter at 500 miles and replacement of the second and third filters after 3,000 miles each. After three filter changes, replacement can be done once a year.

Removing contaminates such as the casting sand and metal shavings means your engine's water pump, EGR cooler and oil cooler will last longer. This kit is designed to bypass and filter small amounts of the engine’s coolant while your diesel engine is running. The CNC machined billet 6061 aluminum anodized construction filter block attaches to a supplied bracket, which mounts to factory holes so no drilling is required. Filter block includes 2 threaded inlet ports and 1 outlet port. This kit includes all fittings needed for installation. The filter can be easily unscrewed for replacement. We recommend replacement of the first filter at 500 miles with replacement of the second and third filters is at 3,000 miles each. After 3 changes, filter replacement can be done once a year. The silicone hoses fittings are pre-assembled for simple, leak-proof connections that factory tested at twice the recommended radiator cap pressure. 

Features:

• Construction - 6061 Aluminum Filter Block, Silicone Hose
• Product Design - CNC Machined 6061 Aluminum, Anodized in Sinister Blue
• Performance Notes - Cleaner coolant for longer engine life
• Special Note - Recommended Tools: 9/16”, 13/16” wrench, 8mm socket, 3/8” 12 point socket or 5/16” combination wrench, large adjustable wrench, regular screw driver, utility knife, diagonal cutters

FAQ's

• Q: What is the installation time for this product?
• A: The Sinsiter Diesel Coolant Filer Bypass system takes approximately 2 hours for installation. Installation time may vary based on experience.
• Q: Why do I need a Coolant Filtration system?
• A: From the factory, many engine blocks will have sand, from the casting process, still in the cooling channels. If not filtered out, the sand can clog EGR coolers or cause premature wear of water pumps or coolant seals. Our Sinister Diesel Coolant Filtration System is a stylish and affordable "insurance" against premature failures from debris in the coolant system.
