-----------------

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

Radiator

Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.

1C-LTC and 2CL-TC Engines

1. Position a suitable drain pan under the radiator and drain the cooling system by opening the radiator draincock.

6. Disconnect the upper and lower hoses from the radiator.
7. Disconnect the water temperature switch connector.
8. On vehicles equipped with automatic transaxle, disconnect the two cooler hoses from the cooler pipes.

Take care when disconnecting the cooler lines because some of the transmission oil will leak from the line. Place a small plastic container under the lines to collect the oil and plug each connection to prevent further leakage.

9. Remove the two bolts and radiator supports.
10. Remove the radiator from the vehicle.

To install:

11. Place the radiator in position and support it by hand. Install the two radiator supports with bolts. Make sure that the rubber cushion of each support is not depressed or crimped.
