radiator cap CHEVROLET VENTURE 1998 Owners Manual

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.

A CAUTION:
Steam and scalding liquids from a hot cooling
system can blow out and burn you badly. They
are under pressure, and
if you turn the radiator
pressure cap
-- even a little -- they can come out
at high speed. Never turn the cap when the
cooling system, including the radiator pressure
cap, is hot. Wait for the cooling system and the
radiator pressure cap to cool
if you ever have to
turn the pressure cap.

2. Then keep turning the pressure cap, but now push
down as you turn
it. Remove the pressure cap.
1.
You can remove the radiator pressure cap when the
cooling system, including the radiator pressure cap and
upper radiator hose, is
no longer hot. Turn the pressure
cap slowly counterclockwise until it first stops. (Don’t
press down while
turning the pressure cap.)
If you hear a hiss, wait for that to stop. A hiss means
there is still some pressure left.

Checking Coolant If this light comes on, it
The engine coolant reservoir
is located on the driver’s
side
of the vehicle, above the air cleaner. means you’re low
on
engine coolant.
Adding Coolant
If you need more coolant, add the proper DEX-COOL@
coolant mixture
at the coolant recovery tank.
When your engine is cold, the coolant level should
be at FULL COLD, or a little higher. When your engine is warm, the level should
be above the FULL
COLD mark, or a little higher.
Add coolant mixture at the recovery tank, but be careful
not to spill it. ’hrning the radiator pressure cap
when the
engine and radiator
are hot can allow steam and
scalding liquids to blow out and burn you badly.
With the coolant recovery tank, you will almost
never have to add coolant
at the radiator.
Never turn the radiator pressure cap
-- even a
little -- when the engine and radiator are hot.

Thermostat
Engine coolant temperature is controlled by a thermostat
in the engine coolant system. The thermostat stops the
flow
of coolant through the radiator until the coolant
reaches a preset temperature.
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.
Radiator I ressure Cap
NOTICE:
Your radiator cap is a 15 psi (105 kPa)
pressure-type cap and must be tightly installed to
prevent coolant
loss and possible engine damage
from overheating. Be sure the arrows on the cap
line up with the overflow tube on the radiator
filler neck.
When you replace your radiator pressure cap,
a GM cap
is recommended. When you replace your thermostat, a
GM thermostat
is recommended.

Steering Fluid
'l'kv Gower steering fluid reservoir is located to the right
of the windshield washer fluid reservoir, at the back of
the engine compartment.

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should be
performed at least twice a year (for instance, each spring
and fall).
You should let your dealer’s service department
or other qualijied service center do these jobs. Make sure
any necessary repairs are completed at once.
Proper procedures to perform these services may be
found in a service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front Drive A: 3
Boot and Seal Inspection
Inspect the front and rear suspension and steering system
for damaged, loose or missing parts, signs
of wear or lack
of lubrication. Inspect the power steering lines and hoses
for proper hook-up, binding, leaks, cracks, chafing, etc.
Clean and then inspect the drive axle boot seals for
damage, tears or leakage. Replace seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body near
the exhaust system.
Look for broken, damaged, missing or
out-of-position parts as well as
open seams, holes, loose
connections
or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into
the vehicle. See “Engine Exhaust”
in the Index.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect
all pipes, fittings
and clamps; replace
as needed. Clean the outside of the
radiator and air conditioning condenser. To help ensure
proper operation, a pressure test
of the cooling system and
pressure cap is recommended at least once a year.
Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts as
needed. Replace
any components that have high effort
or excessive wear.
Do not lubricate accelerator and
cruise control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and hoses
for proper hook-up, binding, leaks, cracks, chafing, etc.
Inspect disc brake pads for wear and rotors for surface
condition.
Also inspect drum brake linings for wear and
cracks. Inspect other brake parts, including
drums, wheel
cylinders, calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or conditions
result in frequent braking.
