When the temperature climbs

Check in order: coolant level, drive belt (for the water pump), thermostat opening, radiator airflow and fan operation, then the water pump itself. A sudden overheating usually means loss of coolant or a broken belt/pump.

  • Never open the cap when hot — severe burns
  • A 50/50 mix of coolant and distilled water protects from -35 °C to above 130 °C
  • Coolant also prevents corrosion and lubricates the water pump
  • Use the manufacturer’s coolant type (e.g. OAT, G12)

FAQ

Le ventilateur ne s’enclenche pas, ou seulement avec la clim. À vitesse, l’air passe ; à l’arrêt, il n’y en a pas.
50/50 est la norme. Moins protège du gel ; plus de ~70 % réduit l’échange de chaleur.
