How to Add Coolant to the Coolant Surge Tank If you haven't found problem yet, but coolant level a the isn't at FULL COLD, add 50/50 mixture of clean a water (preferably distilled) and DEX-COOL coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. (See "Engine Coolant', the Index in for more information.) TM Steam and scalding liquids from cooling a hot system can blow out burn you badly. They and are under pressure, and you turn the coolant if surge tank pressure cap even a little they can come outat high speed. Neverturn the cap when the cooling system, including the coolant surgetank pressure cap,is hot. Wait for the cooling system and coolant surge tank pressure capto cool if you ever have to turn the pressure cap. -- -- ~ 5-16
