These heavy industrial G-drive setups prioritise dual-layer electronic safety. The primary NTC sender provides a rolling data stream so the operator can read live temperatures (like eighty-five degrees), while a totally independent mechanical temperature switch acts as a hard backup safety line, cutting engine fuel automatically if a wiring loom melts.

No, the high-temperature alarm will be entirely real. If an alternator or fan belt slips, the mechanical water pump will spin too slowly, disrupting the rapid circulation of coolant through the block galleries. The temperature sensor is simply doing its job by reporting the rapid heat buildup before terminal damage occurs.

Thermal drift happens when inferior internal elements degrade from repeated heating and cooling cycles, altering their baseline electrical resistance values. The sensor might read ninety degrees when the engine glycol is actually climbing past a dangerous one hundred and five degrees, blinding the controller to a thermal emergency.
