• Mishimoto Lifetime Warranty

DESCRIPTION

The Mishimoto Chevrolet Duramax low-temperature thermostats activate at a lower temperature than the OEM thermostats, making them the perfect solution for Duramax owners who live in warmer climates or use their trucks under heavy load or strenuous driving conditions. Activating at a lower temperature means coolant will begin flowing through the system and allow for cooler temperatures.

PURCHASE INCLUDES

(1) 174°F Thermostat
(1) 180°F Thermostat
Mishimoto Lifetime Warranty

The Mishimoto Chevrolet Duramax high temperature thermostats activate at a higher temperature than the OEM thermostats, making them the perfect solution for Duramax owners who live in colder climates, or have trouble reaching operating temperatures.Activating at a higher temperature means the thermostats will allow the coolant to stay in the engine longer delaying the coolant flowing through the radiator, which allows the engine to warm up sooner.

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. 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.

It's premixed with deionized water, so it's ready to use and safe for all water-cooled engines, protecting against boilover to 265 F and freezing to -26 F (with 15 psi cap)**. 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.

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.

The XDP X-TRA Cool Direct-Fit Replacement Radiator XD295 is an upgrade for the old leaking radiator in your 2001-2005 GM 6.6L Duramax LB7 and LLY. While the X-TRA Cool may resemble a stock replacement, the construction and design is far from it! The X-TRA Cool Radiators are specially designed with upgraded techniques borrowed from the semi-truck and HD industry. Unlike the OEM radiator, extra steps are taken to ensure added durability and strength to protect your cooling system.
High Efficiency Core
XDP's X-TRA Cool Radiators are built with a high efficiency core that has more fins per inch, and heavy-duty tubes to maximize cooling capabilities.
Internal Reinforcements
For added strength, special aluminum brazing techniques are used during construction. The reinforced end tubes and added strength at the outside corners protect the core where it is most vulnerable.
Gasket Design
X-TRA Cool Radiators feature a proprietary rubber gasket designed to withstand expansion, contraction, and the flex in the front end of your truck.
Revised End Tanks
Reinforcement ribs are strategically added to the end tanks to strengthen weak points. The plastic mix includes a fiber reinforcement that is added during tank construction to provide more strength over the factory tanks.
Upgraded Mounting Points
To allow the X-TRA Cool Radiator to stay securely mounted in the same factory location as the stock radiator, the mounting points have been upgraded for added strength and longevity.
Tank Attachment
To attach the end tanks to the core on the X-TRA Cool Radiator, a heavy gauge steel crimp strip is used instead of aluminum like the factory design. The heavy duty crimp helps eliminate tank and core separation failures that many experience with the factory radiator.
Features:

• Direct-Fit Replacement
• Upgraded Design For Increased Durability
• High-Efficiency Core To Maximize Cooling
• XD295 Specifications:
• Row Quantity: 1
• Core Width: 34 inch

Proper heat management from the cooling system is crucial on modified engines when you want trouble-free and reliable performance. The factory Duramax water pump is known to slip under load and can serious problems and serious repair bills on modified high-horsepower applications. This updated design is a drop-in replacement for the factory water pump and uses precision TIG welds to secure both the impeller and pump gear to the shaft. If your 2001-2005 Duramax powered truck is running a tuner, a bigger turbo, or bigger injectors, or if it's just time for routine maintenance, get peace of mind with the Sinister Diesel Welded Duramax Water Pump.

Features:

• TIG welded on both Impeller and Gear for high strength and slip-free operation
• Drop-in replacement for LB7/LLY factory water pump
• Meets or exceeds OEM specifications

Includes:

• Sinister Diesel "Welded" Water Pump

FAQ's

• Q: Is there a warranty for this product?
• A: This Sinister Diesel part is manufactured and tested right here at Sinister’s California headquarters and comes with a limited lifetime warranty.
• 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.
