If No Steam Is Coming From Your Engine An overheat warning, along with a low coolant light, can indicate a serious problem. See Low Coolant Warning Light on page 3-30. If you get an engine overheat warning with no low coolant light, but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you: Climb a long hill on a hot day. Stop after high-speed driving. Idle for long periods in traffic. Tow a trailer. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. In heavy traffic, let the engine idle in NEUTRAL (N) while stopped. If it is safe to do so, pull off the road, shift to PARK (P) or NEUTRAL (N) and let the engine idle. 2. Turn on your heater to full hot at the highest fan speed and open the window as necessary. 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 three minutes while you're parked. If you still have the warning, turn off the engine and get everyone out of the vehicle until it cools down. You may decide not to lift the hood but to get service help right away. 5-28

If
No
Steam
Is
Coming
From
Your
Engine
An overheat warning, along with a low coolant light, can
indicate a serious problem. See
Low Coolant Warning
Light
on page
3-30.
If you get an engine overheat warning with no
low
coolant light, but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a
little too hot
when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning
with
no
sign
of
steam,
try this for a minute or
so:
1.
In heavy traffic, let
the
engine idle in NEUTRAL
(N)
while stopped. If
it
is
safe
to do
so,
pull off the
road,
shift to PARK
(P)
or NEUTRAL
(N)
and let the
engine idle.
2.
Turn on your heater to full hot at
the
highest
fan
speed and open the
window as necessary.
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 three minutes while
you’re
parked. If
you still
have the warning,
turn
off
the
engine and get
everyone
out
of
the vehicle
until
it
cools down.
You may decide not to lift the
hood
but
to
get
service
help right away.
