Shell DEX-COOL® Extended Life Antifreeze/ Coolant Typical
Concentrate Typical
Pre-diluted 50/50
Code No. 94040 94070
Appearance Orange Orange
Specific gravity 60/60 °F 1.130 1.06
Freezing point, °F (ASTM D 1177)
50 vol. % q.s. aqueous solution -34
Freeze point, ºF, as purchased -34
pH (ASTM D 1287), 1:2 dilution with water 8.3 8.3
Reserve Alkalinity (ASTM D 1121), as received 6.0 3.0
Silicate, % (as Anhydrous Alkali Metasilicate) None None
Recommended dilution for Shell DEX-COOL® 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-COOL® 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-COOL® 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-COOL® 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.
