The water temperature sensor plug is turned when the fan is unplugged" means that there is no problem with the fan and the fan control circuit, to be precise, it should be a temperature control switch, not a water temperature sensor; If it is not used (the temperature control switch is good), it means that there is a problem with the water circulation, either there is a lack of water or the air in the waterway is not discharged, or there is a problem with the water pump, the water is not pumped, the water is not circulating, of course, the actual temperature cannot be sensed, and the worst result is that the cylinder bed is flushed, the water strings into the oil channel, and the oil enters the water channel. The water pipes are inflated and the temperature is not sensitive.

It's so serious upstairs.
Recently, I've had this problem with my Liberty.
It's like this: before, in the morning, the cool car fire does not love, to hit three or four times before starting, just go to a small repair shop to see, he gave a change to a water temperature plug (of course, very cottage kind), but I replaced the one (is Bosch's, it seems that the original brand is not bad) put it away, after the trial of this fault has improved, nothing else has been noted, and then the weather is getting hotter, when the traffic jam is found that the water temperature rises vigorously, all hear the sound of water boiling, the fan does not move, sometimes I am afraid to turn off the car, I went to the repair shop again, they looked for it, they just couldn't find the problem, and they changed a water temperature plug and it still didn't work, but unplugged the water temperature plug and the fan turned, the same as the landlord's, I guess it may be a problem with the new water temperature plug, I took out the original Bosch that I replaced before, and it was all OK when I replaced it, and they were also helpless, but the morning start or returned to the original problem, and it took three or four times to start. I don't know why.

Summary. Let's see if there is any problem with the fan and the fan control circuit, to be precise, it should be a temperature control switch, not a water temperature sensor; If it is not used (the temperature control switch is good), it means that there is a problem with the water circulation, either there is a lack of water or the air in the waterway is not discharged, or there is a problem with the water pump, the water is not pumped, the water is not circulating, of course, the actual temperature cannot be sensed, and the worst result is that the cylinder bed is flushed, the water strings into the oil channel, and the oil enters the water channel. The water pipes are inflated and the temperature is not sensitive.
Hello, I am the answerer, I have provided consultation to nearly 3,000 people, and the cumulative service time of spring rent is long, including 700 hours!

Hello! I don't remember very clearly, there seem to be two fans on the Liberty Ship, but one is a radiator (water tank) fan and the other is a condenser (air conditioner) fan, if this is the case, it is possible that a single radiator fan is rotating at high speeds.
Another possibility is that the fan motor is broken, or the fan resistance is broken.
For the sake of your car, it's a good idea to have it overhauled, after all, this is about the engine and safety.
& Installing the tail drum has little effect on the dynamics, if the tail drum is not suitable, not only the sound is not good, but also the dynamics will be reduced. The "turbofan" of the intake pipe does a bit of a role in the power boost, which is not very noticeable. >>>More
