Causes of an Overheating Engine

The cooling system of an engine is designed as a sealed system with the engine coolant held under pressure. When under pressure, water and engine coolant boil at a higher temperature. As your coolant and water increase in temperature and approach the boiling point, the state of the liquid begins to change to a gas, seen as steam.

The main cause of high water temperature? There are many reasons for the high water temperature. Here are some examples that I can easily judge: Insufficient coolant causes high water temperature. It is easy to judge when the coolant is low

 · Even in perfectly sealed engines, water intrudes and forms condensation within the engine. For every gallon of gasoline burned, a little more than a gallon of water vapor forms as a byproduct. During the course of longer trips, the engine reaches its ideal operating temperature, and the heat causes any condensed water to evaporate.

Engine knocking

This sudden increase in pressure and temperature causes the distinctive diesel 'knock' or 'clatter', some of which must be allowed for in the engine design. Careful design of the injector pump, fuel injector, combustion chamber, piston crown and cylinder head can reduce knocking greatly, and modern engines using electronic common rail injection.

Causes (and cures) of Erratic Engine Temperature Swings

Causes (and cures) of Erratic Engine Temperature Swings Engines do not rise in temperature and immediately drop so it is likely you have air trapped in your cooling system. Air rises to the top of the cooling system and gets trapped, causing the cooling system to vapor lock.

Water In Oil Contamination

The Effects of Water Contamination. In a lubricating system, the two most harmful phases are free and emulsified water. In journal bearings for example, the incompressibility of water relative to oil can result in a loss of the hydrodynamic oil film that in turn leads to excessive wear. As little as one percent water in oil can reduce the life expectancy of a journal bearing by as much as 90.
