1998 CHEVROLET VENTURE engine

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection
you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
I NOTICE:
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles
involved in the jump
start procedure. Put an
automatic transaxle in PARK
(P).
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or the accessory power outlet. Turn
off all
lamps that aren’t needed as well as radios. This will
avoid sparks and help save both batteries. In
addition, it could save your radio!
4. Open the hoods and locate the batteries. Find
the positive
(+) and negative (-) terminals on
each battery.
I CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands,
clothing and tools
away from any underhood
electric fan.

A CAUTION:

Fans or other moving engine parts can injure you
badly.
Keep your hands away from moving parts
once the engine
is running.
5. Connect the red positive (+) cable to the positive (+)
terminal of the vehicle with the dead battery. Use a
remote positive
(+) terminal if the vehicle has one.
6. Don’t let the other end
touch metal. Connect it
to the positive
(+)
terminal of the good
battery. Use a remote
positive
(+) terminal if
the vehicle has one.
... ,
7. Now connect the
black negative
(-) cable
to the good battery’s
negative
(-) terminal.
Don’t let the other end touch anything until the next step. The other end
of the negative (-) cable doesn 1 go
to the dead battery. It goes to a heavy unpainted metal
part on the engine
of the vehicle with the dead battery.

8. Attach the cable at least
18 inches
(45 cm) away
from the dead battery,
but not near engine parts
that move.
The electrical
connection is just
as
good there, but the
chance of sparks getting
back to the battery is
much less.
9. Now start the vehicle with the good battery and run
the engine for
a while.
If it won’t start after a few tries, it probably
needs service.
10.
Try to start the vehicle with
the dead battery.
11. Remove the cables in reverse order to prevent
electrical shorting. Take care that
they don’t touch
each other or
any other metal.

Engine Overheating
You will find a coolant temperature gage on your
vehicle’s instrument panel.
See “Engine Coolant
Temperature Gage” in the Index.
You also have a low
coolant level light on your instrument panel. See “Low
Coolant Light’’ in the Index.
Overheated Engine Protection
Operating
Mode
Should an overheated engine condition exist, an
overheat protection mode which alternates firing groups
of three cylinders helps prevent engine damage. In this
mode, you will notice a significant loss in power and
engine performance. The low coolant light may come
on
and the temperature gage will indicate an overheat
condition exists. This emergency operating mode allows
your vehicle to be driven to a safe place in an
emergency. Towing
a trailer in the overheat protection
mode should be avoided.
NOTICE:
I
After driving in the overheated engine protection
operating mode, to avoid engine damage, allow
the engine to cool before attempting any repair.
The engine oil will be severely degraded. Repair
the cause of coolant loss and change the
oil. See
“Engine Oil, When
to Change” in the Index.

If Steam Is Coming From Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see
or hear steam coming
from it. Just turn it
off and get everyone away
from the vehicle until it cools down. Wait until
there is no sign
of steam or coolant before you
open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out
of the vehicle until the
engine
is cool.
I NOTICE:
If your engine catches fire because you keep
driving with no coolarmt, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty. See “Overheated
Engine Protection Operating Mode” in the Index.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be
too serious. Sometimes
the engine can get a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high-speed driving.
0 Idle for long periods in traffic.
0 Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (D)
or THIRD
(3).
If you no longer have the overheat warning, you
can drive. Just to
be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and
park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops. But then, if you still have the
warning,
turn ofthe engine and get everyone out of the
vehicle
until it cools down. Also, see “Overheated
Engine Protection Operating Mode” listed previously in
this section.
You may decide not to lift the hood but to get service
help right away.

When you decide it’s safe to lift the hood, here’s what
rou’ll see:
i. Radiator Pressure Cap
3. Electric Engine Fans
3. Coolant Recovery Tank
A CAUTION:
I
An electric engine cooling fan under the hood can
start
up even when the engine is not running and
can injure you. Keep hands, clothing and tools
away from any underhood electric fan.
If the coolant inside the coolant recovery tank is boiling,
don’t
do anything else until it cools down.

ProCarManuals.com

The coolant level should be at or above the
FULL COLD mark.
If it isn't, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else
in
the cooling system.
A 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.
