Recommended dilution
for Shell DEX-COOLŪ Extended Life Antifreeze/Coolant
concentrate:
Boiling Protection, °F (C)
(15 lb. pressure cap) 50% (1 part AF/1 part water) 265 (129.4)
Freezing Protection, °F (C)
40% (2 parts AF/3 parts water) -12 (-24.4)
50% (1 part AF/1 part water) -34
(-37.2)
60% (3 parts AF/2 parts water) -61
(-51.7)
Note:
For optimum year
round protection against freezing, boiling and corrosion, a 50 percent
Shell DEX-COOLŪ Extended Life Antifreeze/Coolant concentrate solution (1
part AF/1 part water) is recommended. For maximum protection against
freezing in extremely cold areas, a 60 percent solution (3 parts AF/2
parts water) can be used. Concentrations greater than 67 percent or less
than 40 percent are not recommended. Shell DEX-COOLŪ Extended Life
Antifreeze/Coolant Pre-diluted 50/50 should be used as purchased. No
further dilution is recommended. Dilution of a 50/50 mixture by more than
10% with conventional coolants or water will reduce corrosion and freeze
point protection.
Handling and Safety Information
Shell DEX-COOLŪ Extended Life Coolant has a shelf life
of at least 8 years. Concentrate product should be mixed before use.
Always dispose of used coolant in accordance with local, state and federal
guidelines. These products are not to be used to protect the inside of
potable water systems against freezing. |
