Green Mountain Non-toxic Antifreeze/Coolant Green Mountain Antifreeze is a propylene glycol based non-toxic antifreeze/coolant for use in automotive and heavy-duty engines.  It provides engine protection comparable to, if not better than, ethylene glycol based coolants without the toxicity hazards associated with ethylene glycol. (Universal Formula Pre-charged for Heavy Duty Use) Also available in ready-to-use 50% premix

• Green Mountain meets or exceeds performance requirements for both automotive and Heavy Duty cooling systems, including those with aluminum heat rejecting components such as aluminum cylinder heads, water pumps and radiators.  It provides corrosion protection for all cooling system metals and is compatible with propylene glycol based antifreeze/coolants of all major producers.  It is pre-charged to protect heavy duty truck engine cooling components such as wet sleeve liners.  Green Mountain antifreeze/coolant should not be used in concentrated form in your vehicle.  A 50% dilution is generally recommended for best balanced protection against corrosion and summer boiling.  Do not dilute to less than 33 2/3%  (Maximum freeze protection is at 70% if required.)  Water quality can be an important factor affecting the long-term corrosion protection of any antifreeze.  Avoid use of contaminated or heavily chlorinated water.  Test coolant annually or at maintenance intervals, replace when depleted or, if testing is not done, replace every two years.
• For HVAC systems, recreational vehicles, and protection of other hydronic systems, consult your sales representative for product recommendations.

• Exceeds the requirements of ASTM D6210 and the corrosion limits in ASTM D3306, ASTM D4985, SAE/J1034, SAE/J1941, and Federal Specification OA548D; satisfying both Host Surface Aluminum protection requirements of ASTM test D4340 and Cummins Heavy Duty Low Silicate requirements, and is designed to meet the requirements of TMC RP-330, GM1825M, GM1899M, Chrysler MS7170, and Ford ESEM97B44A.

• No adverse effect on gaskets, hoses, or automotive finishes.

• Protects all materials common to water supply systems, including metals and plastics (except acetates). Keeps seals and rubber parts flexible.
