@ ne-oving the radiator cap while the engine
is hot can cause the engine coolant to splay out, seri-
ously scalding you. Always let the engine and radiatol
cool down betore removing the radiator cap.
CAUTION: When poudng engine coolant, be sure to shut
the relay box lid and not to let coolant spill on the elec-
tlical pans or the paint. ll any coolant spills, rinse it otf
immediately.
1. Slide the heater temperature control lever to maxi-

Make sure the engine and radiator are cool to the
touch.
2. Remove the radiator cao.
3. Loosen the drain plug on the bottom of the radiator,

6. Tighten the radiator drain plug securely.
7. Mix the recommended antifreeze/coolant with an
equal amount of water in a clean container.
NOTE:
. Use only HONDA-RECOMMENOED antifreeze/
coolant.
a For best corrosion protection, the engine coolant
concentrations must be maintained year-round at
50% MINIMUM. Coolant concentrations less than
50% may not provide sufficient protection
against corrosion or freezing.
CAUTION:
a Do not mix ditterent blands ot anti-freeze/
coolants.
a Do not use additional rust inhibitois or anti-rust
products; they may not bs compatibl€ with the

or loose wires at all connectors rolated to the cilcuit that you are troubleshooting (see illustration b6low).
a Most ot tho troublashooting flowchans have you reset the Engine Control Module (ECM) and try to duplicate the Disg-

a ,,opon,'and ,,short,, are common electrical terms. An open is a break in a wir6 or at a conn€ction. A short is an
accidontal connaction ot a wir€ to ground or to another wire. In simple electronics, this usually means som€thing won't
work at all. In complex electronics (like ECM's), this can sometimes mean something wolks, but not the way it's sup-

Fast ldle Thermo Valve
DEscliptlon
To prevent erratic running when the engine is warming
up, it is n€cessary to raise the idle speed. The fast idle
thermo valve is controlled by a thermowax plunger, When
the engine is cold. the engine coolant su.rounding the
thermowax contracts the plunger, allowing additional air
to be bypassed into the intake manifold so that the en-
gine idlss taster. When the engine reaches operating tem-
peratur€, the valve closss, reducing the amount of air
bypassing into the manifold.

Rcgulator Valve
The r€gulator valve maintains a constant hydraulic pressure from the oil pump to the hydraulic control system, whil€
alEo furnishing oil to the lubricating system and torque convener.
Oil flows through B and B'. The oil which enters through B flows thfough the valve orifice to A, pushing the regulator
valve to the right. Acco.ding to the level of hydraulic pressure through B, the position of the valve changes, and the
amount of the oil thlough D from B'thus changes. This operation is continued. thus maintaining the line pressure.

Siator Reaction Hydtaulic Pressure Control
Hydraulic pressure increase, according to torque, is performed by the regulator vslve using stator torque reaction. Thestator shaft is splined to the stator and its a.m end contacts the fegulator spring cap. When the car is accelerating orclimbing (Torque Convener Range). stator torque reaction acts on the stator shalt and the stator shaft arm pushes thersgulator spring cap in this - direction in proportion to the reaction. The spring compresses and the regulator valve movesto increase the regulated control pressure or line pressure. Line pressure is maximum when the stator reaction is maximum.
