marine temperature gauge with alarm

• 2023-02-09

When the water temperature of the marine's engine is too high, the water temperature gauge will alarm. Fault phenomenon of high water temperature: the engine water temperature pointer swings to the red area; The cooling fan is in the maximum state; Insufficient coolant; When the car is driving, the power suddenly disappears, and there are severe knock and knock on the cylinder , which are mostly caused by overheating of the engine. The normal water temperature of the engine is between 85-95 degrees Celsius . When the water temperature is too high, the viscosity of the oil will become thinner , the lubricating performance will decline, and the piston, valve and other components are easy to deform when running at high speed , resulting in engine weakness .

The causes and solutions of the high water temperature of the engine that requires overhaul are as follows:

1.The engine temperature is too high due to insufficient cooling water in the cooling system, so it is necessary to stop and add coolant after the engine cools down ;

2.The engine temperature is too high due to the loose or broken water pump and fan belts, so it is necessary to go to the maintenance shop to replace relevant parts ;

3.The radiator shroud or radiator core ventilation duct is blocked by sundries, resulting in poor heat dissipation, which leads to high engine temperature. It is necessary to replace the heat shield or clean the sundries ;

4.The engine temperature is too high due to insufficient engine oil or substandard oil quality. Just replace the high-quality oil .

Treatment method for high water temperature: if the water temperature is too high due to the loss of coolant, a small amount of distilled water can be added for emergency (note that do not open the water tank cover when high temperature, there is a risk of scalding); For the problem of high water temperature caused by vehicles driving for a long time, you can pull over, turn on the hazard warning light, and then let the vehicle naturally cool down; If the cooling fan is damaged, it is also necessary to find the nearest maintenance shop for maintenance as soon as possible; When the thermostat is damaged, the small circulation should be blocked during disassembly, so as to ensure that the coolant is completely dissipated by the water tank .
