         2) Align crankshaft sprocket mark with mark on lower timing
belt cover. See Fig. 10. Install timing belt around camshaft sprocket.
Rotate tensioner clockwise until Timing Belt Tension Scale (VW 210)
reads 13-14. Rotate crankshaft 2 revolutions and check timing mark
alignment. To complete installation, reverse removal procedure.

         REMOVAL
         1) Remove upper timing belt cover. Place crankshaft at TDC
with No. one cylinder on compression stroke. Remove timing belt from
camshaft sprocket. Remove camshaft sprocket. Remove Woodruff key.
Install camshaft sprocket bolt and washer until washer is tight
against camshaft.
         2) Rotate inner part of Oil Seal Extractor (2085) outward 2
turns and tighten set screw. See Fig. 11. Lubricate threaded area of
extractor and push in as far as possible. Loosen set screw and turn
inner part of extractor until oil seal is removed.
         INSTALLATION
         Coat new seal seat and lips lightly with engine oil. Using
Installer (10-203), install seal until flush. On 16-valve engines, use
Special Hex Head Bolt (10-203/1). To complete installation, reverse
removal procedure.Fig. 11:  Removing Camshaft Oil Seal

         Discharge system. Remove compressor from vehicle. Drain oil
from compressor through inlet and outlet holes. Refill compressor with
3.4-4.7 ounces of oil through suction port. When replacing evaporator,
add 2 ounces. When replacing other A/C components, add 1.4 ounces per
component replaced.
         NIPPONDENSO ROTARY VANE DRAIN & REFILL
         1) Before checking and adjusting oil level, operate
compressor at engine idle speed, and set controls at maximum cooling
and high blowing speed for 20-30 minutes to return oil to compressor.
         2) Stop engine. Discharge refrigerant and remove compressor
from vehicle. See SERVICING PRECAUTIONS at the beginning of this
article. Drain compressor oil through compressor intake and discharge
ports. Measure amount drained. Oil may be hard to drain if compressor
cool. Drain compressor while compressor is warm.
         3) If amount drained is less than 2.4 ounces, conduct leak
tests at system connections. If necessary, repair or replace faulty
parts. Check purity of oil level and adjust oil level as follows.
         4) If amount drained is more than 2.4 ounces, oil level is
okay; fill with same amount drained using new oil. If amount drained
is less than 2.4 ounces, pour 2.4 ounces of new refrigerant oil.
         5) When replacing condenser, add one ounce. when replacing
other A/C components, add .33 ounce per container replaced.
         NIPPONDENSO 6 & 10-CYL DRAIN & REFILL
         When inspecting system for oil loss, look for signs of
leaking (shiny, wet spots on components or underside of hood). If oil
leak is noted or component replacement is required, use the following
procedure as indicated:
         NO OIL LEAK
         Discharge system and change components as necessary. See
SERVICING PRECAUTIONS at the beginning of this article. Add
refrigerant oil to components as necessary.
         OIL LEAK
         1) Slowly discharge system. Repair or replace faulty
components. If equipped with a drain plug, remove plug, drain and
discard oil. If not equipped with a drain plug, remove compressor from
vehicle and pour oil out suction and discharge ports.
         2) Replace drain plug (if equipped). Add 1.5 ounces of new
refrigerant oil through suction port. Use new gaskets or "O" rings
when replacing suction and discharge lines.
         COMPRESSOR FAILURE OR SYSTEM CONTAMINATED
         If either situation exists, discharge system and remove

This Graphic For General Information Only
         On sticking lifters, disassemble and clean lifter. DO NOT mix
lifter components or positions. Parts are select-fitted and are not
interchangeable. Inspect all components for wear. Note amount of wear
in lifter body-to-camshaft contact area. Surface must have smooth and
convex contact face. If wear is apparent, carefully inspect cam lobe.
         Inspect push rod contact area and lifter body for scoring
or signs of wear. If body is scored, inspect lifter bore for damage
and lack of lubrication. On roller type lifters, inspect roller for
flaking, pitting, loss of needle bearings and roughness during
rotation.
         Measure lifter body O.D. in several areas. Measure lifter
bore I.D. of cylinder block. Some models offer oversized lifters.
Replace lifter if damaged.
         If lifter check valve is not operating, obstructions may be
preventing it from closing or valve spring may be broken. Clean or
replace components as necessary.
         Check plunger operation. Plunger should drop to bottom of the
body by its own weight when assembled dry. If plunger is not free,
soak lifter in solvent to dissolve deposits.
         Lifter leak-down test can be performed on lifter. Lifter
must be filled with special test oil. New lifters contain special test
oil. Using lifter leak-down tester, perform leak-down test following
manufacturer's instructions. If leak-down time is not within
specifications, replace lifter assembly.
         Lifters should be soaked in clean engine oil several hours
prior to installation. Coat lifter base, roller (if equipped) and
lifter body with ample amount of Molykote or camshaft lubricant. See

         TIMING BELT INTERFERENCE CAUTION
NOTE:    CAMSHAFT DRIVE BELTS OR TIMING BELTS - The condition of
         camshaft drive belts should always be checked on vehicles
         which have more than 50,000 miles. Although some
         manufacturers do not recommend replacement at a specified
         mileage, others require it at 60,000-100,000 miles. A
         camshaft drive belt failure may cause extensive damage to
         internal engine components on most engines, although some
         designs do not allow piston-to-valve contact. These designs
         are often called "Free Wheeling". Many manufacturers changed
         their maintenance and warranty schedules in the mid-1980's to
         reflect timing belt inspection and/or replacement at
         50,000-60,000 miles. Most service interval schedules shown in
         this section reflect these changes. Belts or components
         should be inspected and replaced if any of the following
         conditions exist:
      *  Crack Or Tears In Belt Surface
      *  Missing, Damaged, Cracked Or Rounded Teeth

flash for approximately 3 seconds in odometer display window as
ignition is turned on. When servicing becomes due (every 7500 miles),
appropriate service code will flash for approximately 60 seconds. The
four service codes available for display are as follows:
     *  IN 00 (No Service Necessary)
     *  OEL (Oil Change Service) Every 7500 Miles
     *  IN 01 (Inspection Service) Every 15,000 Miles
     *  IN 02 (Additional Servicing Work) Every 30,000 Miles
         2) After performing required maintenance, each effected
service code displayed must be reset individually. For example, at 15,
000 miles service codes OEL and IN 01 will both need to be reset.
         3) To reset service codes, turn ignition on. Press and hold
odometer reset button located below speedometer. While holding button,
press clock reset button (lower button for digital clock) located to
left of fuel gauge. Release buttons. Programming mode is now
activated. Service code OEL1.S (distance counter) should be displayed.
         4) Press clock reset button once more. 7500 miles should now
be indicated on display. Desired mileage for reset may be attained by
pressing clock reset button. Mileage displayed will decrease in
increments of 500 miles each time button is pressed. This feature
