426 hemi water temp gauge

• 2022-11-16

The normal operation of the car 426 hemi engine requires a certain operating temperature. Too high or too low is not conducive to the normal operation and performance of the engine. On the other hand, the heat generated by the engine operation is difficult to meet the needs of conventional air cooling, so the car 426 hemi engine widely uses the water-cooled heat conduction plan. The role of the cooling system is to keep the engine operating within the most favorable temperature range, so as to improve the engine power and reduce engine wear and fuel consumption. Too high or too low temperature will adversely affect engine operation.

When encountering the alarm of too high water temperature, we should first slow down, and then drive the car 426 hemi to the roadside. Don't rush to shut down the engine, because too high water temperature will lead to too high temperature of the piston, steel wall, cylinder, crankshaft, etc., and the oil will become thinner and lose lubrication. If the 426 hemi engine is shut down at this time, the parts are in expansion state, and the clearance between the parts is very small. After shutdown, some soft metals fall off, and some even cause cylinder sticking. Therefore, do not turn off the ignition immediately after the boiler is opened, but keep idling for a while and try to cool down.

Just be careful not to open the water tank cover when the car 426 hemi is hot to avoid being burned by the water vapor ejected by the internal strong pressure. If the water volume is enough, check the fan behind the water tank. The fan should be running even after it is turned off when the water temperature is high. If the fan does not move, turn the fan blade first to see if the fan motor is stuck. It can be easily turned when it is normal. If there is no problem with the motor, the fan fuse should be checked, which is one of the reasons for frequent occurrence, especially in summer when the power consumption is high. The thermostat failure is also a frequent cause of high water temperature. Once it fails, the cooling water circulation will be cut off. When touching the two thick glue pipes above and below the water tank, there is an obvious temperature difference, the thermostat is damaged and needs to be removed and replaced, which is generally handled by professionals.
