Bars Leaks has some of the anti-corrosives in it. The real fun is in what's in the patented Bar's Leaks powder. You've heard the tip about using finely ground pepper so it swells and fills small leaks? The BL powder is mostly crushed ginger, and has some powdered walnut shell in it! It works, so why ask?Ranger said:Most any brand of green coolant is good. One gallon of coolant mixed 50/50 will equal 2 gallons and should be enough but check the owners manual to be sure. Don't forget to pick up some cooling system suppliment (sealnt tabs).
