Replacing the heat sink cooling system
Radiator be replaced when it detects a leak of the coolant. The workshop which has the special equipment, the radiator can be checked and repaired. To remove the heat sink assembly is more convenient with electric.
A WARNING Remove the radiator on a cold engine only. |
You will need: the key "10", pliers with long thin jaws, flat-blade screwdriver. | | 2. Disconnect the harness connector of the main fan by clicking on a spring clamp. | 3. Similarly disconnect the connector harness additional fan. |
| | 4. Loosen the clamp of steam-hose to the expansion tank, squeezing it with pliers bent tabs, slide the clamp on a hose ... | 5. ... and remove the hose from the radiator pipe. |
| | 6. Loosen the hose clamp securing the supply ... | 7. ... and disconnect the hose from the radiator pipe. |
8. Similarly disconnect the discharge hose from the water distribution pipe.
NOTE Replacing the heat sink cooling system is shown by the example of the car Chevrolet Lanos. |
| | 9. Remove the bolt of the upper radiator support bracket to the upper cross frame radiator ... | 10. ... and remove the bracket assembly with pillow top support. |
11. Similarly remove the second upper radiator support. 12. Remove the heat sink assembly with the fan assembly from the engine compartment.

Remove them from the cross, if they remained in her hole, or remove them from the pins and check. Highly crimped or hardened, replace the cushions. Similarly, remove the cushion from the upper bracket supports, inspect and replace if necessary. |

Leaking radiator is determined by the emerging air bubbles. If the radiator does not fit fully into the container, check it consistently from all sides. 21. Install the radiator outlet hose and electric fans in reverse order of removal. 22. Install the heat sink on the car in reverse order of removal.
HELPFUL ADVICE To further exclude the possibility of leakage of the coolant, before installing grease fittings radiator hose with a thin layer of silicone sealant. |
