Engine Overheating - Chevrolet SS Sedan 2017 Owner's Manual

284 Vehicle Care
If no coolant is visible in the engine
coolant recovery reservoir, add
coolant as follows:
1. Locate the radiator cap. See
Engine Compartment Overview
0 274.
2. Cover the radiator cap with a
thick cloth and turn it slowly
counterclockwise and remove.
3. If there is no coolant visible or
the level is low, slowly fill the
system through the radiator
cap opening with a 50/
50 mixture of clean, drinkable
water and DEX-COOL coolant
until full.
Wait 30 seconds for the
coolant to settle and top off if
the level drops.
Do not spill coolant on the
accessory drive belts.
If a spill occurs, rinse the belt
with fresh water.
4. Start the engine.
5. With the engine idling, top off
the coolant through the radiator
cap opening until full.
Wait 30 seconds for the
coolant to settle and top off if
the level drops.
6. Once the system is full, put the
radiator cap back on by turning
clockwise.
7. Turn the engine off.
8. Check the coolant level in the
engine coolant recovery
reservoir and fill it until the
level is at the top mark on the
dipstick cap. Filling to this level
provides additional coolant to
allow for any air that may be
left in the cooling system.
Caution
If the pressure cap is not tightly
installed, coolant loss and
possible engine damage may
occur. Be sure the cap is properly
and tightly secured.
