The mixture that is poured into the Renault 19 at the factory consists of 65% water and 35% antifreeze «GLACEOL AL» (Type «WITH»). With this composition of the mixture, the coolant remains in a liquid state up to -23°C, and only at -28°C does it begin to thicken. Below are the mixture ratios for various engine modifications:
Engine | All quantity including heating, l | Antifreeze additive, l | Water, l |
1.4 liter (C3J) | 5,4 | 1,9 | 3,5 |
1.7 liter (F3N) | 6,0 | 2,1 | 3,9 |
1.8 liter (F3P) | 6,5 | 2,3 | 4,2 |
16 valve (F7P) | 7,0 | 2,5 | 4,5 |
Diesel (F8Q) | 6,8 | 2,4 | 4,4 |
Diesel with turbocharger (F8Q) | 7,1 | 2,5 | 4,6 |
As an antifreeze additive, monoethylene glycol is usually used - an alcohol-based liquid that does not evaporate or thicken. Just as important as the antifreeze additive is the corrosion protection additive. It prevents the formation of scale and rust in the cooling system. Factory-filled coolant keeps the engine cool at all times. After 3 years, antifreeze and anticorrosion additives lose their properties. In this case, it is necessary to completely replace the coolant.
To do this, you can use any antifreeze additive that contains a component to protect against corrosion. A prerequisite is compliance with Renault recommendations. Be sure to check the manufacturer's table of this tool, which indicates its composition.
