Best Antifreeze Coolant Additive

Six Feet Under - The Complete Third Season

Yellow-colored, longer-life, ethylene glycol-based antifreeze/coolant for use in gasoline and diesel engines.
Provides year-round antifreeze, anti-boil and corrosion protection.
50/50 mixture of coolant and distilled water provides freeze protection down to -34°F (-37°C) and boiling protection up to 265°F (129°C).
Do not mix different colors or types of coolant in your vehicle.

ORIGINAL: The original global extended life antifreeze/coolant.
QUALITY: Works for all heavy-duty diesel, gasoline and natural gas engine cooling systems.
PROTECTION: Provides a total cooling system protection for all on-road and off-road heavy duty engines.
DURABILITY: Coolant, designed to last the lifetime of the engine.
HEAVY-DUTY: Antifreeze car coolant cooling system solution, whose long-term.

CUTTING EDGE TECHNOLOGY - We at Red Line created this industry, pushing bubbles out of the way to ensure efficient and effective engine cooling.
ULTIMATE COOLING PERFORMANCE - Coolant additive with a unique agent that lowers temperatures by reducing and eliminating bubbles or vapor barrier that form on hot metal surfaces.
PERFORM AND PROTECT - Waterwetter protects from rust and corrosion, allowing the use of straight water in racing or reduced antifreeze levels in warm climates.
EASY TO USE - Use one bottle for most cars and light trucks, treats 3 to 5 gallons. Larger cooling systems should use 2 bottles.
small cooling systems should use 1oz per quart.
WHY RED LINE - Established in 1979, Red Line Products perform and protect better than any on the market. No compromises.

...ling system.(Need vacuum pump and not included in the kit) Add coolant in vacuum, there is no large air pocket and avoid warping or other damage in engine. Normally, it takes 5-10mins to refill the coolant, the exact time depends on the size of the tank. Easy to operate and save time.
WIDELY USAGE RADIATOR PURGE AND ANTIFREEZE REFILL TOOL: JIFETOR antifreeze filler kit includes a universal tapered rubber adapter, with MIN. diameter 1.5CM and MAX. diameter 5CM, fits for almost all types of vehicles. The adapter can replace the radiator cap to seal the cooling system, and connect with the quick coupler on coolant refiller to help to fill antifreeze..
WATER TANK COOLANT VACUUM REFILL: Plastic covered premium brass manifold body, equipped with brass fittings, anti-corrosion and durable. The index range of gauge is -30~0inHg (-76~0cmHg), and normally -25~-20inHg is right time to add coolant. 18" rubber resin material weave reinforced hose, featured with anti-corrosion, low fluid resistance, high bearing pressure, ensure durability and good air sealing. Also there is a 21" metal chain hook for hanging on the engine hood..
ACCESSORIES: There are 2 styles air plugs in the case for you to choose, European style air plug and a American style one (pre-installed on....

4-in-1 Tester - Measuring Freezing of automoblie antifreeze based on ethylene glycol or propylene glycol -60℉ to 32℉. Measuring Specific Gravity of battery acid 1.10 to 1.40Kg/L. Measuring of Windshield Washer Fluid based on ethanol or isopropyl alcohol -40℉ to 32℉. Measuring Urea Concentration in automobile diesel exhauset fluid (DEF) 30% to 35%.
Display In Fahrenheit - Updated antifreeze coolant refractometer in Fahrenheit (℉) display, allow you easy to read measured results by ℉ unit, no need to units conversion and save your time.
ATC Function - Coolant refractometer Fahrenheit can automatically compensate temperature when ambient temperature changes, eliminate the deviation, you can get the accurate results fast and easier.
Easy To Use - Only need 2 or 3 drops of solution and wait for few seconds, then you get the accurate results. These antifreeze tester needs less sample solution than tradistional hydrometer and less expensive then digital refractometer.
Durable And Portable - Antifreeze coolant tester is made of aluminum and ABS rubber, non-staining, anti-rust and stury for long perfermance. Comes with durable plastic box, portable and easy to take with you.
