To prevent the entry of dust or other foreign bodies, plug the dismantled hoses and
compressor nipples. << B >> COMPRESSOR REMOVAL Take care not to spill any compressor oil when removing the compressor. INSTALLATION SERVICE POINT >> A << COMPRESSOR INSTALLATION If a new compressor is installed, first adjust the amount of oil according to the
procedures described below, and then install the compressor.
1. Measure the amount [X cm
3 (X fl.oz) of oil within the removed compressor.
2. Drain (from the new compressor) the amount of oil calculated according to the
following formula, and then install the new compressor.
New compressor oil amount = 140cm

CAUTION: As the compressor oil and receiver are highly
moisture absorbent, use a non-porous material to
plug the hose and nipples.
NOTE:
Y cm
3 (Y fl.oz) indicates the amount of oil in the refrigerant
line, the condenser, the evaporator, etc.
NOTE: When replacing the following parts at the same times as the
compressor, subtract the rated oil amount of each part from
Y cm3 (Y fl.oz) and discharge from the new compressor.

handling R-134a.
R-134a evaporates so rapidly at normal atmospheric pressures and temperatures that
it tends to freeze anything it contacts. For this reason, extreme care must be taken to
prevent any liquid refrigerant from contacting the skin and especially the eyes.
Always wear safety goggles when servicing the refrigeration part of the A/C
system. Keep a bottle of sterile mineral oil handy when working on the refrigeration
system.
1. Should any liquid refrigerant get into your eyes, use a few drops of mineral oil
to wash them out.
R-134a is rapidly absorbed by the oil.
2. Next splash your eyes with plenty of cold water.
3. Call your doctor immediately even if irritation has ceased.
In most instances, moderate heat is required to bring the pressure of the refrigerant
in its container above the pressure of the system when charging or adding
refrigerant.
A bucket or large pan of hot water not over 40°C (104.0°F) is all the heat required
for this purpose. Do not heat the refrigerant container with a blow torch or any other
means that would raise temperature and pressure above this temperature. Do not
weld or steam-clean on or near the system components or refrigerant lines.
WARNING:Do not heat R-134a above 40 °C (104.0 °F) or it may
catch fire and explode.
CAUTION: Keep R-134a containers upright when charging the
system.
WARNING:The leak detector for R-134a should be used to
check for refrigerant gas leaks.
CAUTION: Do not allow liquid refrigerant to touch bright metal

2004 STEERING
Power Steering - Endeavor
GENERAL DESCRIPTION Power steering has been adopted in all vehicles to make the steering system easier
to handle.
A 4-spoke steering wheel is used. A steering column has a shock absorbing mechanism and a tilt steering
mechanism. A rack and pinion steering gear is used. An oil pump responsive to engine RPM is used, which, with tuning for a rigid
gear box mount, improves steering stability at high speeds. The separate plastic resin oil reservoir reduces weight and makes fluid level
checking easier.
