Is It Normal for Only One Fan to Spin on the Baojun 730?
2 Answers
This is a normal phenomenon. Only when the air conditioning is turned on in summer and the engine coolant temperature is very high will both fans spin together. Relevant information about the Baojun 730 is as follows: 1. Dimensions: The Baojun 730 is a 5-door, 7-seat MPV under SAIC-GM-Wuling. Its length, width, and height are 4780mm, 1780mm, and 1740mm respectively, with a wheelbase of 2750mm. 2. Powertrain: The Baojun 730 CVT version is equipped with a 1.5T turbocharged engine paired with a simulated 8-speed CVT continuously variable transmission. The engine's rated power is 111kW, and the maximum net torque is 250N·m.
My Baojun 730 has been used for several years, and fan issues are quite common. Under normal circumstances, it might be an energy-saving design feature that only one cooling fan operates, such as during low-speed driving or when the coolant temperature isn't high, with only one fan running for heat dissipation. However, if the temperature gauge rises or the other fan still doesn't spin after turning on the AC, this could indicate a problem, often stemming from a faulty fan motor, relay failure, or a short circuit in the wiring. I personally encountered this issue, which turned out to be due to oxidized relay contacts causing poor connectivity—replacing the relay solved the problem. I recommend you immediately monitor the coolant temperature; if the needle rises too high, pull over promptly to prevent engine overheating damage. Don’t delay—visit a 4S shop as soon as possible for a professional diagnostic tool to check error codes and the electrical circuit, ensuring driving safety. During routine maintenance, remind the technician to pay attention to the fan system to avoid future troubles.
