coolant level HONDA INTEGRA 1998 4.G Workshop Manual

8.Mix the recommended antifreeze with an equal
amount of water in a clean container.
NOTE:
a Use only genuine Honda antifreeze/coolant.
a For best corrosion protection, the coolant concen-
tration must be maintained year-round at 500,6
minimum. Coolant concentrations less than 507o
may not provide sufficient protection against cor,
rosion or freezing.
a Coolant concentrations greater than 60% will im-
pair cooling efliciency and are not recommended.
CAUTION:
a Do not mix different brands of anti-lrcezel
coolants.
a Do not use additional rust inhibitots or anti-tustproducts; they may not be compatible with the
coolant.

Fast ldle Thermo Valve (A/T model onlylFast ldle I nermo valve (A/ | mooel
Description
To prevent erratic running when the engine is warming
up. it is necessary to raise the idle speed. The fast idle
thermo valve is controlled by a thermowax plunger.
When the engine is cold, the engine coolant surround-
ing the thermowax contracts the plunger, allowing addi
tional air to be bvoassed into the intake manifold so that
the engine idles taster. When the engine reaches operat-
ing temperature, the valve closes. reducing the amount
of air bypassing into the manifold.

Inspection
NOTE: The fast idle thermo valve is factory adiusted; it
should not be disassembled.
1. Remove the intake air duct from the throttle body.
2. Start the engine.
3. Put your finger over the lower port in throttle body
and make sure that there is air flow with the engine
cold {engine coolant temperature below 86'F, 30"c).
LOWERPORT
lf there is no air flow, replace the last idle thermo
valve and retest.
Start the engine. Hold the engine at 3,000 rpm with
no load (in Park or neutral) until the radiator fan
comes on, then let it idle.
Check that valve is completely closed. lf not, air suc-
tion can be felt at the lower port in the throttle body.
l{ any suction is felt, the valve is leaking. Check
engine coolant level and for air in the engine
coolant system (see section 10). It OK, replace the
fast idle thermo valve and recheck.

SYMPTOMREMEDY
Hot air tlow is low.Blower motor runs, but one or more
speeds are inoperative.
Follow the flowchart (see page 21-9).
Blower runs propetly.Check for the following:. Clogged heater duct
. Clogged heater outlet
. Incorrect door Position
No hot air tlowBlower motor does not run at all.Follow the flowchart {see page 21-11}
Blower motor runs.Check for the following:
. clogged heater duct
. Clogged blower outlet. Clogged heatet valve
. Faultv air mix door
. Heater valve cable adjustment lsee page 21-27].
. Air mix control cable adiustment {see page 21-27)
. Faulty thermostat (see section 10)
. Clogged evsporator (with air conditioning)
. Frozen evaDorator (with air conditioning)
Mode control motor does not run, or one or more mooes are
inoDeratave.
Follow the flowchart (see page 21-14).
Recirculation control door does not change between FRESH
and RECIRCULATE.
Follow the flowchart {see page 21-17).

tt.Pour Honda All Season Antifreeze/Coolant Type 2into the radiator up to the base of the filler neck.
NOTE:
o Always use Honda All Season Antifreeze/Coolant
Type 2. Using a non-Honda coolant can result incorrosion, causing the cooling system to mal-function or fail.
o Honda All Season Antifreeze/Coolant Type 2 is amixture of 50% antifreeze and 50% water.Premixing is not required.
