Toyota RAV4 (XA40) 2013-2018 Service Manual: Radiator
Components
On-vehicle inspection
- Check radiator reservoir cap subassembly
- Measure the valve opening pressure.
- If there are water stains or foreign matter on oring
1, clean it with water and finger scouring.
- Check that o-ring 1 is not deformed, cracked or
swollen.
- Apply engine coolant to o-ring 1 and rubber
packing 2 before using a radiator cap tester.
- When using the cap tester, tilt it more than 30
degrees.
- Pump the cap tester several times, and check
the maximum pressure*.
Pump speed:
1 pump per second
*: Even if the cap cannot maintain the
maximum pressure, it is not a defect.
Judgment criterion
If the maximum pressure is less than the
minimum standard value, replace the radiator
reservoir cap sub-assembly.
On-vehicle cleaning
- Inspect radiator assembly
- Check that the radiator and condenser are not
blocked with leaves, dirt, or insects. Clean the hose
connections.
If the fins are blocked, wash them with water or a
steam cleaner.
Notice:
- If the distance between the steam cleaner and
core is too close, the fins may be damaged.
- Keep the following injection distance.
Standard injection distance
- If the fins are bent, straighten them with a
screwdriver or pliers.
- Never apply water directly onto the electronic
components.
- Dry the fins with compressed air.
