REMOVAL AND INSTALLATION
1. Drain engine coolant. Refer to MA section, ªChanging Engine
Coolantº.
2. Remove left side battery. (If so equipped)
3. Remove radiator upper hose.
4. Remove radiator shroud.
5. Remove intake air duct, inlet pipe.
6. Remove harness and connectors.
7. Install in reverse order of removal.
IAfter installation, run engine for a few minutes and check
for leaks.
IBe careful not to spill coolant in engine compartment. Use
a rag to absorb coolant.
INSPECTION
1. Check valve seating condition at ordinary temperatures. It
should seat tightly.
2. Check valve opening temperature and maximum valve lift.
Valve opening temperature ÉC (ÉF) 82 (180)
Maximum valve lift mm/ÉC (in/ÉF) 10/95 (0.39/203)
3. Then check if valve closes at 5ÉC (9ÉF) below valve opening
temperature.
Water Outlet
INSPECTION
Visual inspection for water leaks. If there is leakage, replace gas-
ket.
