Liquid coolants

The engine coolant is a heat transfer fluid.
Its function is to maintain the engine at an ideal operating temperature. It is maintained under pressure and circulates between the engine and the radiator.
It consists of water with an additive such as ethylene glycol or propylene glycol in order to raise the boiling point and increase it resistance to freezing.

Provide one of the best liquid coolants to your Engine Cooling systems with other Valeo Protectiv® solutions:
Protectiv® 40, Protectiv® 50, Protectiv® 100 and Protectiv® 112.

Valeo Protectiv® 35
Valeo Protectiv® 35 is a high-quality ready-to-use liquid coolant containing about 35% of mono-ethylene glycol.
Protectiv® 35 is based on hybrid (G11) technology with mineral and organic additives (corrosion inhibitors, anti-deposit, antifoam and others).
Protectiv® is available in a 4 litre bottle in Green/Blue and Pink.
Protectiv® 35 Valeo part numbers:
- 4 Litre green/blue bottle: 820697
- 4 Litre pink bottle: 820698
Valeo Protectiv® 35 ready-to-use liquid coolant allows a high thermal conductivity and thus protects your Engine Cooling loop from freezing and overheating.
Protectiv® 35: Temperature protection: -20°C to +105°C (atmospheric pressure)
The high quality of Valeo Protectiv® 35 avoids:
- Corrosion: Electrochemical process in which a metal reacts with its
environment to form an oxide or other compound.
- Scale deposits and cavitation phenomenon:
Chemical reactions in your engine cooling circuit can engender scales
deposits and thus the cavitation phenomenon, which will damage your water
pump. (photo scale deposits & cavitation)

Valeo Protectiv® 40 & Protectiv® 50
Valeo Protectiv® 40 & Protectiv® 50 are high quality ready-to-use liquid coolants and respectively containing about 40% and 50% of mono-ethylene glycol.
Protectiv® 40 & Protectiv® 50 are in accordance with carmakers' norms such as DAIMLER DBL 7700.30, MAN 324-NF, Volkswagen 774 D/F & MTU MTL 50 48 based on Organic (G12) technology with 100% organic additives (corrosion inhibitors, anti-deposit, antifoam and others).
Protectiv® 40 is available in a 5 litre bottle in green/blue: Valeo part number 820699.
Protectiv® 50 is available in a 5 litre bottle, 25 litre can and 1000 litre tank in yellow & pink:
Protectiv® 50 Valeo part numbers:
- 5 litre yellow bottle: 820700
- 5 litre pink bottle: 820871
- 25 litre yellow can: 820705
- 25 litre pink can: 820706
- 1000 litre yellow tank: 820718
- 1000 litre pink tank: 820719

Valeo Protectiv® 40 and Protectiv® 50 ready-to-use liquid coolants allow a high thermal conductivity and thus protect your Engine Cooling loop from freezing and overheating with a temperature range protection depending on the concentration of mono-ethylene glycol.
- Protectiv® 40: Temperature protection: - 25°C to +106°C
(atmospheric pressure)
- Protectiv® 50: Temperature protection: - 35°C to +108°C
(atmospheric pressure)

The high quality of Valeo Protectiv® 40 & Protectiv® 50 components prevents:
- Corrosion: Electrochemical process in which a metal reacts with its
environment to form an oxide or other compound.
- Scale deposits and cavitation phenomenon:
Chemical reactions in your engine cooling circuit can engender scales
deposits and thus cavitation, which will damage your water
pump. (photo scale deposits & cavitation)

Valeo Protectiv® 112 & Protectiv® 100
Valeo Protectiv® 112 & Protectiv® 100 are high-quality concentrated antifreezes containing over 90% mono-ethylene glycol.
Protectiv® 112 & Protectiv® 100 are in accordance with carmakers norms like DAIMLER DBL 7700.30, MAN 324-NF, VW 774 D/F & MTU MTL 50 48 based on Organic (G12) technology with 100% organic additives (corrosion inhibitors, anti-deposit, antifoam and others). Protectiv® 112 is available in a 1 litre pink bottle: Valeo part number 820872.
After dilution, Valeo Protectiv® 112 & Protectiv® 100 concentrated antifreezes allow a high thermal conductivity and thus protect your Engine Cooling loop from freezing and overheating with temperature range protection depending on the dilution.

The high quality of Valeo Protectiv® 112 & Protectiv® 100 components prevents
- Corrosion: Electrochemical process in which a metal reacts with its
environment to form an oxide or other compound.
- Scale deposits and cavitation:
Chemical reactions in your engine cooling circuit can engender scale
deposits and thus cavitation, which damages your water
pump. (photo scale deposits & cavitation)

Valeo info: The coolant should be replaced every 2 years, over time it loses its cooling, anti-corrosive and anti-freeze properties.
