98. How to determine if a cold oil cooler is leaking? (Including high oil pressure and high water pressure.)
A large amount of leakage can be determined through changes in the fuel tank level and bearing temperature； A small amount of leakage can be determined by regularly taking lubricant samples for analysis.
Make sure to check the oil tank level. If the oil pressure is higher than the water pressure, the level drops rapidly, which may indicate a leak in the cold oil cooler. If oil is present in the return water from the cold oil cooler, it also indicates a leak there. If the oil tank level rises, and a large amount of water can be drained from the bottom of the tank or if the oil contains water, this suggests that the water pressure is higher than the oil pressure, indicating a leak in the cold oil cooler.
Be sure to check the oil tank level. 1. If the oil pressure is higher than the water pressure, the oil level drops rapidly; this may indicate a leak in the cold oil cooler. 2. If the oil pressure is lower than the water pressure, oil appears in the return water from the cold oil cooler, which also indicates a leak there. If the oil tank level rises and a large amount of water can be drained from the bottom of the tank, or if the oil contains water, it means that the water pressure is higher than the oil pressure, indicating a leak in the cold oil cooler.
I would like to ask whether, under normal conditions, it is the circulating water pressure that is high or the lubricating oil pressure
Oil mist detection can be used; I’m not sure if it’s for pipelines
