EGR cooler replacement Puma 2.2

Yes the 2.2 does have the thermal protection, and will cut throttle response if it gets too hot. I think though that stopping the engine before is better. The trouble with these systems that the temp reading is only being read from a single position, and other parts of the engine could already be dry and getting much hotter than the area with the sensor.

Many engine protection systems use a pressure sensor instead so that a leak can be recognised way before coolant levels drop too much....

It wont stop the EGR heat exchange from physically failing, it may reduce the chance but thats just my passing thought and is not based on any factual evidence.

Low coolant alarms are the best way to protect from failures due to coolant loss.

If coolant drops off the primary temp sensor you have no chance.
