Suzuki Big Dipper big fan cooling difficult problem to solve

A mileage of about twelve,000 km, equipped with K12 engine Changan Suzuki Major Dipper. Consumers report: car or truck cooling fan won't do the job, leading to the water temperature is also high, the engine is bursting water pipes.

Check the examination: the upkeep workers consider the car, the primary substitute of the new water pipes, and include a great coolant, and after that start out the engine and continue to operate for some time, coolant temperature progressively increased until finally the temperature is as well substantial, the fan even now operate, indicating that cooling there are actually problems together with the system.



Then, the maintenance personnel from the vehicle cooling technique circuit is checked. According towards the circuit diagram, we are able to see the engine handle unit voltage signal acquisition coolant V45.06 CK100 key programmer temperature sensor so that you can decide the level from the coolant temperature. Once the temperature is too substantial, the engine handle unit controls the cooling fan relay, cooling fan operation, which lowers the engine coolant temperature.

Maintenance personnel in the engine coolant temperature is as well higher, unplug the cooling fan connector, check accessibility lamp cooling fan power measurement terminal, in no way found energy. Subsequently, the maintenance employees get a good cooling fan connector, the battery back-end, inside the left front suspension, come across the cooling fan relay, the relay testing. Initially, load shorting relay connector at each ends of your wire, you may see the fan is running, indicating BMW ICOM A2+B+C the line is usual. The inspection, maintenance personnel discovered traces of rust relays have water, then remove the relay case, plainly see the relay internal corrosion leading to bad perform, bringing the bring about recognized.

Troubleshooting: Replacing the cooling fan relay, start the automobile, when the coolant reaches a particular temperature, the cooling followers are working, troubleshooting.
