Coolant Surge Tank Pressure Cap; Checking Coolant; Adding Coolant; Engine Overheating - Suzuki reno 2006 Owner's Manual

Checking Things Under the Hood:
SERVICE AND APPEARANCE CARE
If you have to add coolant more than four
times a year, have your dealer check your
cooling system.
CAUTION
If you use the proper coolant, you
don't have to add extra inhibitors or
additives which claim to improve the
system. These can be harmful.

Checking Coolant

The engine coolant surge tank is located
on the driver's side of the engine compart-
ment. See "Engine Compartment Over-
view" in this section for more information
on location.

Never turn the surge tank pressure
cap – even a little – when the engine
and radiator are hot.
Loosening the surge tank pressure
cap when the engine and radiator are
hot can allow steam and scalding liq-
uids to blow out and burn you badly.
The vehicle must be on a level surface.
When your engine is cold, the coolant level
should be between MAX and MIN mark on
the coolant surge tank. The level rises at
engine operation temperature and drops
again when the engine cools down.

Adding Coolant

If the level falls below the MIN mark, add
the proper coolant mixture at the surge
tank, but only when the engine is cool. If
the surge tank is empty, a special fill pro-
cedure is necessary. See "Cooling Sys-
tem" in this section for instructions on "How
to Add Coolant to the Coolant Surge
Tank".
Don't spill coolant on a hot engine.
You can be burned if you spill cool-
ant on hot engine parts. Coolant con-
tains ethylene glycol, and it will burn
if the engine parts are hot enough.

When replacing the pressure cap, make
WARNING sure it is hand-tight.

Engine Overheating

You will find a coolant temperature gauge
on your vehicle's instrument panel. See
"Engine Coolant Temperature Gauge" in
section 3.
WARNING
CAUTION
Your coolant surge tank cap is a
pressure-type cap and must be
tightly installed to prevent coolant
loss and possible engine damage
from overheating. See "Capacities
and Specifications" for more infor-
mation.
