How to Add Coolant to the Coolant
Surge Tank
If you have not found a problem yet, check to see
if coolant is visible in the surge tank. If coolant is
visible but the coolant level is not at or above the
FULL COLD mark, add a 50/50 mixture of clean,
drinkable water 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
on page 415 for more information.
If no coolant is visible in the surge tank, add
coolant as follows:
{ CAUTION:
Steam and scalding liquids from a hot
cooling system can blow out and burn
you badly. They are under pressure,
and if you turn the radiator pressure
cap — even a little — they can come out
at high speed. Never turn the cap when
the cooling system, including the radiator
pressure cap, is hot. Wait for the cooling
system and radiator pressure cap to cool
if you ever have to turn the pressure cap.
