INSTALLATION
1. INSTALL TIMING BELT
(a) Check the No. 1 and No. 2 belt idlers.
(1) Visually check the seal portion of the idler pulley for oil leakage.
-
If leakage is found, replace the idler.
(2) Check that the idler turns smoothly.
-
If necessary, replace the idler.
|
(b) Check the water pump.
(1) Visually check the air hole and water hole for coolant leakage.
-
If leakage is found, replace the water pump and belt.
(2) Turn the pulley, and check that the water pump bearing moves smoothly and quietly.
-
If necessary, replace the water pump.
|
|
(c) Remove any oil or water on the crankshaft, oil pump pulley, water pump pulley, No. 1 and No. 2 belt idlers. Keep them clean.
NOTICE:
Only wipe the pulleys. Do not use any cleansing agents on the pulleys.
(d) Set the No. 1 cylinder to TDC/compression.
(1) Turn the hexagon head portion of the camshaft to align the timing marks of the camshaft timing pulleys and timing belt plates.
HINT:
Turn the camshaft timing pulleys slightly clockwise to make installation of the timing belt easier.
