What are the reasons for the high water temperature of the Baojun 730?
2 Answers
The high water temperature of the Baojun 730 can be caused by many reasons, mostly due to insufficient coolant, a faulty thermostat, water pipe leakage, or insufficient cooling water. Common causes include a broken fan belt, radiator or water pipe leakage, thermostat failure, and engine oil leakage. Below is a detailed introduction about the Baojun 730: 1. Dimensions: The length, width, and height of the Baojun 730 are 4780 mm, 1780 mm, and 1740 mm respectively, with a wheelbase of 2750 mm. The car offers a spacious interior, which has made it popular among consumers since its launch. The Baojun 730 is known for its high cost-performance ratio. 2. Engine: The Baojun 730 is equipped with two types of engines: a 1.5-liter turbocharged engine and a 1.5-liter naturally aspirated engine. The 1.5-liter turbocharged engine delivers a maximum power of 108 kW and a maximum torque of 250 Nm, with the maximum power achieved at 5200 rpm and the maximum torque between 2200 to 3400 rpm. This engine features DVVT technology and multi-point fuel injection, and it uses an aluminum cylinder head and cast iron cylinder block. It is paired with either a 6-speed manual transmission or a CVT. The 1.5-liter naturally aspirated engine produces a maximum power of 77 kW and a maximum torque of 135 Nm, with the maximum power achieved at 5600 rpm and the maximum torque between 3600 to 5200 rpm. This engine also features DVVT technology and multi-point fuel injection, and it uses an aluminum cylinder head and cast iron cylinder block. It is paired with a 6-speed manual transmission. 3. Suspension: The Baojun 730 uses a MacPherson independent suspension at the front and a torsion beam non-independent suspension at the rear. Most MPV models use a torsion beam suspension at the rear to maximize interior space.
I've been driving for over twenty years and have encountered overheating issues several times with my Baojun 730. The most common cause is insufficient or leaking coolant, especially during long summer drives when evaporation is more likely. Another reason could be a faulty thermostat stuck in the closed position, preventing coolant circulation for heat dissipation. Radiator blockage is also a problem, where dust or debris clogs the air passages and affects ventilation. The fan not working is another possibility, due to reasons like a short-circuited motor or a faulty temperature control switch. If the water pump is leaking, the engine temperature can spike. I remember once when I was hauling cargo uphill, the temperature suddenly rose, and I found out the coolant had completely leaked out. It's important to regularly check the radiator water level and the fan's operation. If any abnormalities are noticed, stop the car immediately to let it cool down and prevent engine damage.
