e. Disconnect the timing belt from the timing belt idler No.1, and remove the timing belt.
26. INSTALL TIMING BELT
a. Check the timing belt idler No. 1 and No. 2.
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 timing 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 pulley, oil pump pulley, water pump pulley, idler No.1 and idler No.2, and keep them clean.
NOTICE: Only wipe the pulleys; do not use any cleansing agent.
