1998 PONTIAC GRAND PRIX coolant temperature

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It doesn’t take much fluid, generally less
than one
pint
(0.5 L). Don’t ovefill.
LOTICE:
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label
is
made especially for your automatic transaxle.
Damage caused
by fluid other than DEXRON-III
is not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as described
4. When the correct fluid level is obtained, push the
under “How to Check” earlier in this section.
dipstick back in
all the way.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain
in your vehicle for 5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating
or if you need to add coolant to your
radiator, see “Engine Overheating” in the Index.
A 50/50 mixture of water and DEX-COOL’
coolant will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 OF (129°C).
J
e Protect against rust and corrosion.
e Help keep the proper engine temperature.
0 Let the warning lights and gages work as
they should.

Radiator Pressure 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.
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.
When
you replace your thermostat, a GM thermostat
is recommended.
