>>D<< OIL FILTER INSTALLATION 1. Clean the installation surface of the filter bracket.  
2. Apply engine oil to the O-ring of the oil filter.  
3. Install the oil filter to the bracket and tighten it to the specified torque. 
Tightening torque: 14+/-2 N.m (122+/-17 in-lb)  
4. If no torque wrench can be used for tightening, use the following procedure. 
1. Screw in the oil filter until its O-ring contacts the oil filter bracket.  
2. Ti
ghten the oil filter 1 turn.

Q: Is there more noise on the customers radio?  
YES: Check all power and ground connections. If all connections are in 
good condition, consult the radio manufacturers service center.  
NO: The observed noise is normal.  
INSPECTION PROCEDURE 13: Noise is Detected with Engine Running. DIAGNOSIS 
CAUTION:
Never connect a noise filter to the high tension 
cable (spark plug wire). Spark plug wires 
incorporate resistors which have the effect of 
suppressing noise. If a spark plug wire is found 
to be causing noise, it must be replaced.  Confirm that the noise is not from an external 
source.  Noise prevention should be performed by 
suppressing strong sources of noise first.  
NOTE: Voltage surges can be induced in the electrical system by 
the collapse of a field (i.e. When power is removed from the 
coil in an A/C compressor clutch). This induced voltage 
surge will radiate a Radio Frequency (RF) signal that is 
picked up by the audio unit. In the case of the compressor 
clutch a "pop" will be heard through the speakers. The 
capacitor, installed on this vehicle, will store the excess 
voltage and prevent the production of RF noise. This is 
because the capacitor will charge and discharge as the 
voltage fluctuates. This has the effect of "attracting" noise 
and bleeding it to ground without interfering with the 
normal flow of current through the system.

Heater Air Conditioning, Ventilation - Endeavor 
GENERAL DESCRIPTION The heater and cooling units are combined in a single unit, which, with the mode 
film damper and flow rate control valve in the heater unit, reduces ventilation 
resistance, increases fan power, and decreases noise. 
GENERAL SPECIFICATION SAFETY PRECAUTIONS Because R-134a refrigerant is a hydro fluorocarbon (HFC) which contains 
hydrogen atoms in place of chlorine atoms, it will not cause damage to the ozone 
layer. 
Ozone filters out harmful radiation from the sun. To assist in protecting the ozone 
layer, Mitsubishi Motors Corporation recommends an R-134a refrigerant recycling 
device. 
Refrigerant R-134a is transparent and colorless in both the liquid and vapor state. 
Since it has a boiling point of -29.8°C (-21.64°F) at atmospheric pressure, it will be 
a vapor at all normal temperatures and pressures. The vapor is heavier than air, non-
flammable, and non-explosive. The following precautions must be observed when 
handlin
