Be Cool, America's leader in power cooling technology, has done it again with Be Coolant, an Extended-Life, Super Duty Coolant & Antifreeze that is ideal for all applications. Be Coolant features a new-generation earth-friendly biodegradable, propylene glycol formula that protects cooling systems and aluminum components down to 26 degrees below zero (F). Be Coolant provides 300,000 miles of extended-life coolant protection that is ideal for all performance and severe duty applications including American, European, and Asian high performance cars as well as diesel-powered tow vehicles and RVs. Additionally, Be Coolant features a self-sealing capability that is ideal for sealing hairline cracks in aluminum blocks and heads. Be Coolant is made in the USA, is compatible with all colors of coolant and all types of radiators, comes ready to use in recyclable gallon jugs, and is UPS-able. A convenient two gallon master pack is the easiest way to purchase Be Coolant's extended protection. Best of all, Be Coolant doubles a Be Cool radiator's factory warranty.
I used this when install this brand's radiator in my TJ. My engine temps are now 30 lower in the Southern Cali heat. Never above 210 and I've a winch blocking 1/4 my grill.
Use for all engines, especially here you're dealing w/aluminum cooling systems (radiator, pump, heater core, etc). I've even used it on a water-cooled whole-house (LP) generator.
While costly, it's super clean. If you're going to use it, you really need to fully protect your investment by fully flushing your system. DexCool is like drinking toxic rain water, Prestone is like drinking sulfur water from the tap, and Be Cool is like water from a PUR filter. I used it recently on my Vette and will purchase the bigger containers for 2 AMCs I have (one is getting a REMAN'd engine w/Edelbrock heads and an aluminum radiator). I would definitely recommend this product to everyone.
