Checking Coolant
The engine coolant surge tank is located on the
passenger’s side of the vehicle at the rear of the engine
compartment. SeeEngine Compartment Overview on
page 5-12for more information on location.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the
FULL COLD mark or a little higher.
Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixtureto the coolant surge tank,but be careful
not to spill it.
{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.
{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. Do not spill coolant on a hot engine.
Coolant Surge Tank Pressure Cap
Notice: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.

Tire Sealant
The kit contains a liquid sealant that when injected into
a at 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 at tire or
a tire that has had a “blow out” 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.
Using Tire Sealant
Before using the tire sealant, be sure the valve stem
area is clean and free of debris, such as mud, snow, ice,
brake dust, etc. The valve stem should be located at
the bottom of the tire before applying the tire sealant.
To apply the tire sealant, do the following:
1. Turn the valve cap on the tire valve
counterclockwise to remove it.
2. Remove the valve core using the valve core tool
provided in the tire inator kit. An extra valve core
is also provided in the kit.3. Shake the bottle to make sure the sealant is well
mixed.
4. Attach the tire sealant lling hose to the bottle of
tire sealant to pierce the seal on the bottle.
5. Remove the sealing plug from the end of the lling
hose and insert the end of the hose over the tire
valve.
6. Hold the bottle upside down over the tire valve and
squeeze the sealant into the tire until the bottle is
empty.
7. Remove the sealant lling hose from the tire valve
and reinstall the sealing plug.
8. Insert the valve core back into the tire valve. Turn
valve core tool clockwise to secure the valve core.
Once the tire sealant is applied, you can use the
compressor to inate the tire.
