What are the common reasons for frequent water shortage in diesel vehicles?

[BrielleMarie]

Frequent water shortage indicates a leak in the cooling system or a slight head gasket failure. It may also be caused by excessively high coolant temperature leading to system water shortage. Below is relevant information about diesel vehicles: 1. Precautions: Pay attention to excessively high engine water temperature. Park the vehicle in a ventilated and shaded area. Then open the engine hood and wait for the coolant temperature to drop. If it is necessary to open immediately, use a large towel soaked in water to cover the antifreeze reservoir cap before attempting to slowly open it. When steam emerges, quickly move your hand away and wait until the steam completely dissipates before finally opening the cap to add coolant. 2. Scrap time: The vehicle will be mandatorily scrapped when the mileage reaches 600,000 kilometers, but the specific condition of the vehicle should also be considered. For commercial vehicles, the scrap time is 8 years. Each vehicle has its own scrap period from the time of purchase, which is a system designated by the national transportation department, specifying safety inspection regulations based on the number of seats and usage period during the vehicle's service life.
