Precautions
LIQUID GASKET APPLICATION PROCEDURENJLC00011. Use a scraper to remove all traces of old liquid gasket from
mating surfaces and grooves. Also, completely clean any oil
from these areas.
2. Apply a continuous bead of liquid gasket to mating surfaces.
(Use Genuine Liquid Gasket or equivalent.)
+For oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm
(0.138 to 0.177 in).
+For areas except oil pan, be sure liquid gasket diameter is 2.0
to 3.0 mm (0.079 to 0.118 in).
3. Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).
4. Assembly should be done within 5 minutes after coating.
5. Wait at least 30 minutes before refilling engine oil and engine
coolant.

CAUTION:
+When removing water pump assembly, be careful not to
get coolant on drive belt.
+Water pump cannot be disassembled and should be
replaced as a unit.
+After installing water pump, and check for leaks using
radiator cap tester.
1. Drain engine coolant.
Refer to LC-17, ªChanging Engine Coolantº.
2. Remove drive belts and idler pulley.
3. Loosen water pump pulley bolts.
4. Remove water pump pulley.
5. Remove front right wheel.

6. Check drained coolant for contaminants such as rust, corro-
sion or discoloration. If contaminated flush engine cooling
system, refer to LC-19, ªFLUSHING COOLING SYSTEMº.

Ð REFILLING ENGINE COOLANT ÐNJLC0037S021. Install reservoir tank, lower radiator hose and cylinder block
drain plug.
+Apply sealant to the thread of cylinder block drain plug.
: 35 - 44 N´m (3.50 - 4.50 kg-m, 26 - 32 ft-lb)
2. Fill radiator slowly with coolant until coolant spills from the air
relief plug, then install air relief plug.
