The reasons for the difficulty in starting the Ford Transit diesel vehicle in the morning are: 1. Use of high-viscosity engine oil in winter; 2. Excessive carbon deposits in the intake system and at the root of the intake valve, resulting in an overly lean air-fuel mixture during cold starts; 3. Severe throttle valve contamination, leading to insufficient air intake; 4. Transmission lubricating oil viscosity being too thick, causing excessive engine operating resistance; 5. Insufficient cylinder compression pressure in the engine, among others. Taking the 2020 Ford Transit as an example, its front suspension is a MacPherson independent suspension, the rear suspension is a leaf spring non-independent suspension, equipped with a 2.0T turbocharged engine, with a maximum horsepower of 202 PS, a maximum power of 148.5 kW, a maximum torque of 300 Nm, and matched with a 5-speed manual transmission.
It's quite common for my Ford Transit diesel to struggle with cold starts in winter, mainly due to three major components. First, the battery can't handle the low temperatures. Diesel engines already have high compression ratios, and if the battery weakens even slightly, it immediately fails—especially older batteries over five years old; they should be replaced when necessary. Second, there's the fuel system. Diesel fuel gels like lard in sub-zero temperatures, so remember to switch to -10 diesel in advance and drain the water separator monthly, or the fuel lines will clog completely. Lastly, there's the glow plug system—each plug needs to be removed and tested for resistance; if it exceeds 1 ohm, it's done for. Oh, and if the starter motor's carbon brushes are severely worn, it'll just spin noisily without engaging. Honestly, plugging in a block heater half an hour beforehand is the easiest solution.
