Radiator Fan Running when Engine is Off

Описание: Radiator Fan Running when Engine is Off could be due to couple of reasons:
1) Stuck Relay Coil
2) Overheated Engine: this could be due to low coolant level or leakage or even a damaged water pump which doesn't circulate the coolant well enough.

This video is about fixing problem (1) where the relay coil is released upon tapping, allowing the radiator fan to stop running when engine is off.

for Proton Gen2, the relay is PW537074, or any 12V 30A DC relay that could also be modified to fit the pins' fittings.
