water pump may also be broken, i had the same problem and when i replaced the water pump on my 92 camaro i found the inside of the pump was full of build up. try repalcing water pump.
When selecting an electric baseboard thermostat for optimal heating control, consider key features such as programmable settings for customized heating schedules, accuracy in temperature control, compatibility with your baseboard heater system, energy-saving features like timers or sensors, and ease of use for convenient operation.
An open thermostat would keep the engine from heating up to normal operating temperature. The sensors effected can only report what they sense. The "check engine" light may throw a code like "P0116" (engine coolant temperature circuit range/performance problem).
A thermostat uses electrical energy to power its internal circuits and sensors that monitor the temperature. When the desired temperature is reached, the thermostat activates a switch that turns off the heating or cooling system, which uses mechanical energy to control the flow of air or water. The thermal energy comes into play as the thermostat detects temperature fluctuations in the environment and signals the heating or cooling systems to adjust accordingly.
If you mean that the motor is actually heating up and not the meter it could be the result of an broken thermostat or clogged vaterpipes. If you mean by the meter it could be a result of having to little water in the system. The meter relies from the input of 2 different sensors.
You cracked your head.
the thermostat could be stuck closed or the radiator fan is not working. check the fuse or the temp sensor, but be careul because the 94 have 2 sensors. 1 for the fan and 1 for the temp gauge.
sensors are not protected by fuses.
The Mercedes-Benz E220 CDI engine overheating control system primarily utilizes a combination of cooling components and sensors to maintain optimal operating temperatures. It features a thermostat that regulates coolant flow to the engine and radiator, ensuring efficient heat dissipation. Additionally, the engine management system monitors temperature sensors, adjusting fan speeds and coolant circulation accordingly to prevent overheating. If temperatures exceed safe limits, the system can trigger warning lights or even reduce engine power to protect against damage.
On my 1988, O2 sensor is threaded into side of exhaust pipe underneath near transmission. When I changed it, it was difficult to remove. I had to keep heating the exhaust pipe with a torch to get it out.
possibly overheating or faulty sensors in cap lid!
Check your TPS and O2 sensors. Could be a bad thermostat. My 94 did that ,changed it and solved problem.
i couldnt tell you pal
