General Information
Use Recommendations -- Pah/nol Formula U900 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 antifreeze/coolants of all major producers. Ethylene Glycol base 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 33.33%. (Maximum freeze protection is at 68% if required.) Water quality is an important factor affecting the long-term corrosion protection of any antifreeze. Avoid use of contaminated or heavily chlorinated water. Use of additional cooling system additives is not needed in automotive systems and is specifically discouraged. The recommended change interval is one year.
For HVAC systems, recreational vehicles, and protection of other hydronic systems, consult your sales representative for appropriate product recommendations.
Applicable Specification -- Exceeds the requirements of ASTMD 3306 and ASTM D4985, SAE J1034, and SAE J1941, Federal Specification OA548D; satisfying both Hot Surface Aluminum protection requirements of ASTM test D4340 and Cummins Heavy Duty Low Silicate requirements, and is designed to meet the requirements of GM1825M, GM1899M, Chrysler MS7170, and Ford ESEM97B44A.
Hoses and Gaskets -- No adverse effect on gaskets, hoses, or automotive finishes.
Cautionary Information -- Ethylene Glycol, the major component in Pah-nol, is poisonous to humans and animals when ingested. Store only in closed containers with complete cautionary warning information thereon, in a cool, secure place, out of reach of children. Do not use in any system connected with potable water. Consult your sales representative for our product for this purpose.
