Conveys the heat

The heat from the engine is propelled by the water pump, conveyed to the radiator and expelled to the outside air.

The media that conveys the heat is the coolant liquid, it circulates in the whole cooling loop. Overheat can cause severe damage to the cooling loop and engine components leading to expensive repair, therefore the choice of good quality coolant will play a key role.

Why and when changing the coolant liquid?

In the long run inhibitor packages break down and progressively no longer protect efficiently the cooling system from various aggressions. The best guide for replacing coolant is time.

Valeo recommends to :
  • Change the coolant every 2 years
  • Benefit from a reparation to change the coolant: Any operation on the engine cooling system requires opening the circuit and removing the coolant, this is always a good opportunity to renew the whole liquid and protect the new components.
  • Flush before fitting: Failures on changed components are often related to poor servicing practices, basic operation as cooling loop flushing permit to secure the servicing operation.
  • Use Valeo Fastfill tool for efficient coolant filling (Valeo part 698798)
Coolant colour

Coolants are the antifreeze. Most antifreeze contains mainly ethylene glycol, which is colourless.
To this base of antifreeze coolant makers add a variety of chemicals that prevent rust and corrosion as well as a solvent to keep those inhibitors in solution and a limited amount of distilled water. Days are added to:

  • be able to see clearly the remaining level of coolant in the tank
  • differentiate one car brand from another
