Oldsmobile 1998 Cutlass - How to Add Coolant to the Coolant Surge Tank

How to Add Coolant to the Coolant
Surge Tank
If you haven’t found a problem yet, but the coolant level
isn’t at
FULL COLD mark or slightly higher, add a
50/50 mixture of clean 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’’ in the Index for more infomation.)
I
Steam and scaldmg liquids from a hot cooling
system can blow out and burn you badly. They
are 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 cap
when the cooling system, including the coolant
surge tank pressure cap, is hot. Wait for the
cooling system and coolant surge
tank pressure
cap to cool
if you ever have to turn the
pressure cap.
