![]() ![]() Your temperature gauge will rise quickly, particularly if it is very warm outside.Ĭooling Fan Motor Failure: If the motor for your radiator cooling fan fails, it will not cycle on. It’s also possible that the sensor is shorting.įailed Thermostat: If your car’s thermostat sticks in the closed position, coolant will not fully cycle through the engine, and it will begin to overheat. The needle may be stuck in the hot range (this can happen after overheating the engine), or a stepper gear in the gauge may be damaged.įailed Temp Sensor: If the temperature sensor on your engine block has failed, it may not send any information to the system, or it may send an erroneous signal, causing the gauge to rise without any actual overheating. However, if the engine isn’t actually hot (the temp gauge is maxed out but there’s no abnormal levels of heat from the engine), this isn’t the problem.īroken Temp Gauge: If the temperature gauge is maxed out but the engine isn’t actually hot, then the problem may be a broken temperature gauge. If this occurs, your engine can overheat, and serious damage can result, up to and including cracking the block. Low Coolant: The first suspected cause of your temperature gauge maxing out is low coolant. Factory diagrams are much harder to read.Service type Temperature gauge is maxed out Inspection offers redrawn diagrams as well as factory diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams. If you’re tracking down a wiring issue, is the better choice. In most cases, their diagrams are right from the factory manuals. They include wiring diagrams and technical service bulletins.
