GMC 2001 C3 - Checking Coolant

6-28
Checking Coolant
The coolant surge
tank is located on the
passenger’s side of the
engine compartment.
See “Engine Compartment Overview” in the Index
for more information on location.
CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the
FULL COLD mark.
If the LOW COOLANT
message comes on and
stays on, it means you’re
low on engine coolant.
See “Low Coolant” in the Index.
