Coolant Temperature Sensor (MR2) R & I: Installation

1. To install, reverse removal procedure. Proper cooling system bleeding procedure must be followed.
2. Remove spare tire, front luggage compartment trim and upper radiator support seal. Connect air bleed hoses to heater and radiator air drain plugs. Attach and support opposite end of hoses to hood or hood support. See Fig 1. Ensure hoses are not pinched.
3. Place heater control lever on instrument panel to warmest position. Open heater and radiator air drain plugs at least 3 turns.
4. Slowly add coolant through coolant filler. Air will bleed from hoses on heater and radiator air drain plugs. Ensure coolant in air bleed hoses and coolant filler are at the same lever.
5. If coolant level in air bleed hoses is lower than lever in coolant filler, air still exists in cooling system. Check for pinched or restriction in air bleed hoses. If necessary, repeat step 4). When proper coolant level is obtained in air bleed hoses, close air drain plugs. Remove air bleed hoses.
