How to Add Coolant to the Coolant Surge Tank If you haven't found problem yet, but the coolant level a isn't at FULL COLD, add a50/50 mixture of clean water (preferably distilled) andDEX-COOL TM coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure is cool cap, before you do it. (See "Engine Coolant" the Index for in more information.) Steam and scalding liquids from a hot cooling system can blow out and burn badly. They are you under pressure, and if you turn the coolant surge tank pressure cap even a little they can come out at high speed. Never turn the capwhen the cooling system,including the coolant surge tank pressure cap, i hot. Waitfor thecooling system s and coolant surge tank pressure cap to cool if you o ever have t turn the pressure cap. -- -- 5-16
