CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the proper
coolant mixture will. Your vehicle's coolant
warning system is set for the proper coolant
mixture. With plain water or the wrong mixture,
your engine could get too hot but you wouldn't
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a 50/50 mixture of clean, drinkable water
and DEX
-COOL
coolant.
NOTICE:
In cold weather, water can freeze and crack the
engine, radiator, heater core and other parts.
So use the recommended coolant.
CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol
and it will burn if the engine parts are hot
enough. Don't spill coolant on a hot engine.

5-17
1. Park the vehicle on a level surface. You can remove
the coolant surge tank pressure cap when the cooling
system, including the coolant surge tank pressure cap
and upper radiator hose, is no longer hot. Turn the
pressure cap slowly counterclockwise (left) about
one
-quarter turn and then stop.
If you hear a hiss, wait for that to stop.
A hiss means there is still some pressure left.
2. Then keep turning the pressure cap slowly,
and remove it.
3. Then fill the coolant surge tank with the proper
mixture, to the FULL COLD mark on the coolant
surge tank.

5-18
4. With the coolant surge tank pressure cap off,
start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fan(s).
By this time, the coolant level inside the coolant
surge tank may be lower. If the level is lower, add
more of the proper mixture to the coolant surge tank
until the level reaches the FULL COLD mark on the
coolant surge tank.5. Then replace the pressure cap. Be sure the pressure
cap is hand
-tight and fully seated.

If a Tire Goes Flat
Your Corvette has no spare tire, no tire changing
equipment and no place to store a tire.
It's unusual for a tire to ªblow outº while you're
driving, especially if you maintain your tires properly.
See ªTiresº in the Index. If air goes out of a tire,
it's much more likely to leak out slowly.
If your vehicle has Extended Mobility Tires (EMT), you
won't need to stop on the side of the road to change a
flat tire. EMT tires can operate effectively with no air
pressure. If you drive on a deflated EMT for 50 miles
(80 km) or less and at speeds of 55 mph (90 km/h) or
less, there is a good chance that the tire can be repaired.
Contact the nearest authorized Chevrolet or Goodyear
EMT servicing facility, as soon as possible, to have the
flat tire inspected and repaired or replaced. For more
information, see ªExtended Mobility Tiresº in the Index.CAUTION:
Special tools and procedures are required to
service an Extended Mobility Tire (EMT).
If these special tools and procedures aren't
used, you or others could be injured and your
vehicle could be damaged. Always be sure the
proper tools and procedures, as described in the
service manual, are used.
To order a service manual, see ªService and Owner
Publicationsº in the Index.

5-20
Z06 models do not have Extended Mobility Tires.
If a Z06 model tire goes flat, avoid further tire and
wheel damage by driving slowly to a level place and
stopping. Then do this:
1. Turn on the hazard warning flashers.
2. Set the parking brake firmly.
3. Put the shift lever (manual transmission)
in REVERSE (R).
4. Turn off the engine.
5. Inspect the flat tire.
If the tire has been separated from the wheel or has
damaged sidewalls or large tears that allow rapid air
loss, call a tire repair facility. See ªRoadside Assistanceº
in the Index.
If the flat tire is due to a slow leak caused by a nail or
other similar road hazard, the tire inflator kit may be
used to repair the damaged tire temporarily. The kit uses
a liquid tire sealant to seal small punctures in the tread
area of the tire. The flat tire is then inflated to at least 26 psi (179 kPa)
and driven to evenly distribute the tire sealant. The tire
pressure is checked after driving for a maximum of
10 minutes to see if the slow leak has been stopped.
If the tire pressure is 19 psi (131 kPa) or more, inflate
the tire up to the standard operating pressure as shown
on the Tire Pressure Label found on the rear edge of the
driver's door. See ªTires, Pressureº in the Index.
You should have the damaged tire repaired as soon
as possible. The tire sealant is a temporary repair only.
For more information regarding the tire inflator kit see
ªTire Inflator Kitº following this section.
NOTICE:
If the tire pressure has dropped below 19 psi
(131 kPa), the vehicle should not be driven
further. Damage to the tire may be severe
and the sealant will not be effective. Contact
Roadside Assistance. See ªRoadside Assistanceº
in the Index.

5-22 Tire Sealant
The kit contains a liquid sealant that when injected into
a flat tire, may temporarily repair nail holes or cuts in
the tread area of the tire. The tire sealant cannot repair
tire damage caused while driving on a flat tire or a tire
that has had a ªblow outº or a tire that has punctures in
the sidewall areas. The tire sealant solution is a one
-time
use application for one tire only. Check the tire sealant
expiration date; the sealant may not be as effective
beyond the expiration date. The tire sealant can be
peeled off easily after drying.
NOTICE:
Do not use a tire sealant if your vehicle is
equipped with Extended Mobility Tires or tire
pressure monitors. The tire sealant can damage
tire pressure monitor sensors. See ªExtended
Mobility Tiresº in the Index.
Air Compressor
The air compressor included in the tire inflator kit, was
designed exclusively for the Z06 Model equipped with
P295/35ZR18 and P265/40ZR17 tires. After the sealant
has been injected into the flat tire, use the air compressor
to inflate the tire to at least 26 psi (179 kPa). Instructions
for connecting and using the air compressor are located
on the air compressor.
A. Inflating Hose
B. Air Pressure GageC. ON/OFF Switch
D. Air Compressor Plug

5-23
NOTICE:
The car engine must be running to avoid draining
the battery while running the air compressor.
Follow the proper steps to be sure your vehicle won't
move. See ªParking Your Vehicle, Manual Transmissionº
in the Index.
CAUTION:
It can be dangerous to get out of your vehicle
with the engine running, if the shift lever is not in
NEUTRAL (N) with the parking brake firmly set
(manual transmission). Your vehicle can roll or
move suddenly even when on fairly level ground.
To be sure your vehicle won't move, always set
your parking brake and move the shift lever to
NEUTRAL (N) when you start or idle your engine.
CAUTION:
Idling the engine in a closed-in place or with
the climate control system off can cause deadly
carbon monoxide (CO). See ªEngine Exhaustº in
the Index.
CAUTION:
Inflating something too much can make it
explode, and you or others could be injured.
Be sure to read the inflator instructions, and
inflate the tire to its recommended pressure.
Do not exceed 36 psi (248 kPa).

5-24
NOTICE:
Do not allow the air compressor to operate
continuously for more than six minutes to help
prevent damage from overheating.
NOTICE:
If 26 psi (179 kPa) tire pressure cannot be
reached after six minutes, the vehicle should not
be driven further. Damage to the tire is severe
and the sealant will not be effective. Remove the
air compressor plug from the accessory power
outlet and unscrew the inflating hose from
the tire valve. See ªRoadside Assistanceº in
the Index.
If 26 psi (179 kPa) tire pressure is reached in six minutes
or less, disconnect the air compressor and attach the
enclosed maximum speed label to the inside upper left
corner of the windshield or to the face of the radio/clock.
The maximum speed
label reminds you to
drive cautiously and
not to exceed 55 mph
(90 km/h) until you
have the damaged tire
inspected and repaired.
Place the air compressor pump and accessories
into the inflator kit case and store in the hatch/trunk
compartment area of your vehicle.
