After-glow control
1. Turn ignition switch OFF.
2. Leave harness connector joined to glow control unit.
3. Connect test lamp to glow control unit as shown in ``Pre-glow
control''.
4. Turn ignition switch to START and return to ON. Measure
terminal voltage and count the times the test lamp turns on
and off.
1) At coolant temperature below 50ÉC (122ÉF) the battery volt-
age appears intermittently for 15 seconds. Test lamp turns on
and off approx. 3 times.
2) At coolant temperature over 50ÉC (122ÉF) the battery voltage
appears for 2 seconds.
Component Inspection
GLOW PLUG CONNECTING PLATE NUTS
Check that all glow plug connecting plate nuts and harness nut
are installed securely.
GLOW PLUG
Remove glow plug connecting plate and perform continuity test
between each glow plug and cylinder head.
No continuity ... Replace glow plug.
Two manufacturer's ceramic glow plugs are provided on
TD25 engine.
A color mark of orange or blue is put on the glow plug head.
Do not mix them in one engine. Do not use if dropped on the
floor.
GLOW RELAY
The glow relay is normally open.

Connecting rod bearing (Big end)
1. Install connecting rod bearing to connecting rod and cap.
2. Install connecting rod cap to connecting rod.
lTighten bolts to the specified torque.
3. Measure inner diameter ``C'' of each bearing.
4. Measure outer diameter ``Dp'' of each crankshaft pin journal.
5. Calculate connecting rod bearing clearance.
Connecting rod bearing clearance
= C þ Dp: mm (in)
Standard
0.010 - 0.035 (0.0004 - 0.0014)
Limit
0.09 (0.0035)
6. If it exceeds the limit, replace bearing.
7. If clearance cannot be adjusted within the standard of any
bearing, grind crankshaft journal and use undersized bear-
ing. Refer to step 7 of ``BEARING CLEARANCE Ð Main
bearing''.

HFC-134a (R-134a) Service Tools and
Equipment
Never mix HFC-134a refrigerant and/or its specified lubricant with CFC-12 (R-12) refrigerant and/or its lubri-
cation oil.
Separate and non-interchangeable service equipment must be used for each type of refrigerant/lubricant.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
Adapters that convert one size fitting to another must never be used: refrigerant/lubricant contamination will
occur and compressor failure will result.
