Testing
Remove the YEL/RED wire from the engine oil pres-
sure swrtcn.
Check for continuity between the positive terminal
and the engine {ground). There should be continuity
with the engine stopped. There should be no conti-
nuity with the engine running.

Start the engine. Shut it off immedjately if the gauge
registers no oil pressure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (fan
comes on at least twice). The pressure should be:
Engino Oil Temperature: 176'F (80'C)
Engine Oil Pressure:
At ldle:70 kPa (0.7 kgt/cm', 10 psil
minimum
Ai 3,000 rpm: 3/r0 kPa {3.5 kgt/cm', 50 psi)
minimum
lf oil pressure in not within specifications, inspect the
oil pump (see page 8-9).

Goolant Temperature Gauge
Gauge Testing
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testin9.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire from the coolant tempera-
ture sending unit. and ground it with a jumper wire.
YEL/GRNWIRE
Turn the ignition switch ON {ll). Check that the
pointer of the coolant temperature gauge starts
moving toward the "H" mark. Turn the ignition
switch OFF before the pointer reaches "H" on the
gauge dial. Failure to do so may damage the gauge.
lf the pointer of the gauge does not move at all,
check for an open in the YEL/GRN wire.
lf the wires are OK, replace the coolant temperature
gauge.
lf the coolant temperature gauge works, test the
coolant temperature sending unit.

Testing
1. Disconnect the YEUGRN wire from the coolant tem

2. Using an ohmmeter, measure the change in resis-
tance between the positive terminal and the engine

at operating temPerature.

3. lf the readings are substantially different from the
specitications above, inspect the coolant level and
the cooling system. lf the cooling system is OK,
replace the sending unit.
