Replacement
1.Using a ring expander, remove the old piston rings.
Clean all the ring grooves thoroughly with a
squared-off broken ring or a ring gtoove cleaner
with a blade to fit the piston grooves.
The top ring groove is 1.2 mm (0.042 in) wide, rhe
second ring groove is 1.2 mm (0.042 in) wide, and
the oil ring groove is 2.8 mm (0.11 in) wide. File
down a blade if necessary.
Do not use a wire brush to clean ring lands, or cutring lands deeper with cleaning tool.
3. Install the new rings in the proper sequence andposition (shown in the right column).
NOTE: lfthe piston is to be separated from the con-
necting rod, do not install new rings yet.

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:

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.
