How To Add Coolant To The Coolant Surge Tank - Chevrolet C6H042 Owner's Manual

CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don't touch them.
If you do, you can be burned.
Don't run the engine if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
NOTICE:
Engine damage from running your engine
without coolant isn't covered by your warranty.
If there seems to be no leak, start the engine again. The
fan speed should increase when idle speed is doubled by
pushing the accelerator pedal down. If it doesn't, your
vehicle needs service. Turn off the engine.
How to Add Coolant to the Coolant
Surge Tank
If you haven't found a problem yet, but the coolant
level isn't at the COLD ADD mark or higher, add a
50/50 mixture of clean, drinkable water and 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 the Caterpillar
Engine Operation & Maintenance Manual for the
proper engine coolant to use.
