< ON-VEHICLE REPAIR >
RADIATOR
WARNING:
Never remove radiator cap when engine is hot. Serious burns could occur from high-pressure engine
coolant escaping from radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to
release built-up pressure. Carefully remove radiator cap by turning it all the way.
1. Remove the following parts:
 Engine under cover.
 Air duct (inlet): Refer to EM-26, "
Exploded View".
 Horn: Refer to HRN-6, "
Exploded View".
 Hood lock: Refer to DLK-220, "
Exploded View".
2. Drain engine coolant from radiator. Refer to CO-8, "
Draining".
CAUTION:
 Perform this step when the engine is cold.
 Never spill engine coolant on drive belt.
3. Disconnect reservoir tank hose from radiator pipe (upper).
4. Disconnect CVT fluid cooler hoses from radiator.
 Install blind plug to avoid leakage of CVT fluid.
5. Disconnect Low-pressure flexible hose from lower pressure pipe, and then move it to aside. Refer to HA-
38, "Exploded View".
6. Remove radiator cap adapter and radiator hoses (upper) and radiator pipe (upper) assembly.
CAUTION:
Be careful not to allow engine coolant to contact drive belt.
7. Disconnect radiator hose (lower) from radiator.
8. Remove condenser. Refer to HA-46, "
Exploded View".
CAUTION:
Be careful not to damage condenser core.
9. Remove radiator upper clip (2) by pulling the tabs (A) outside to
release the lock (B) and then remove mounting rubbers (upper)
(1).
CAUTION:
Never pull the tabs outside excessively to prevent it from
damping.
10. Lift up and remove radiator from front of radiator core support.
CAUTION:
Be careful not to damage or scratch on radiator core.
INSTALLATION
Note the following, and installation is the reverse order of removal.
Radiator Upper Clip
Install radiator upper clip on radiator core connection as follows:
1. Install mounting rubbers (upper) (1) on mounting pins (A) of radi-
ator.
2. Align radiator upper clip (2) with radiator core connection (B),
then insert radiator upper clip straight into radiator core connec-
tions until a click is heard.
3. After connecting radiator upper clip, use the following method to
check it is fully connected.
 Visually confirm that two radiator upper clips are connected to
radiator core connections.
 Move radiator upper clip and the radiator forward and backward to check they are securely connected.
