Santana water tank is short of water.

Hello: According to the above-mentioned vehicle failure phenomenon, combined with the analysis of maintenance experience, if the water tank cover, water tank and cooling system water pipes are well connected, it is recommended to check the following points: 1, warm air water tank; It is suggested to check the performance of the heater tank in the cab to see if there is water seepage. This position is not easy to check. If there is slight water seepage, it will be difficult to find it with the increase of temperature, and there will be water shortage. 2. Cooling system; This fault source judgment mainly checks the performance of the engine cooling system, that is, whether the sealing performance of the engine cylinder gasket has decreased, and secondly checks the damage degree of the cylinder head. Judgment method: It is suggested to go to the repair shop to remind the maintenance technician to use the freezing point instrument to detect whether the exhaust pipe product is below 0, otherwise it will be repaired. 3. Throttle preheating; This situation can be judged by visual inspection, and the throttle preheating water pipe can be checked for corrosion and water seepage. To sum up, according to the previous maintenance situation, it is recommended to go to the repair shop to check the above maintenance suggestions, hoping to bring you help.
