What should the oil temperature read on a peugeot 406 hdi 2003?
The normal operating temperature for the coolant in a Peugeot 406 HDi 2003 should be between 82°C and 102°C (180°F and 216°F). If the temperature gauge is reading higher than this, it could be an indication of a number of underlying faults, and professional repair advice should be sought as soon as possible.
