Wynns CV Crystal Clean And Protect 500Ml (W21090)

Description

Genuine Wynns · Part no. W21090

Safety: Danger. Causes serious eye damage. Read the label before use.

Wynns CV Crystal Clean and Protect (W21090) is a 500ml AdBlue treatment that goes into the AdBlue tank, not the fuel, to stop crystals forming in the SCR system and to dissolve light crystal build-up. A 125ml dose treats a smaller AdBlue tank of 10 to 20 litres, and the full 500ml treats a 45 to 75 litre tank.

Good to know

• Where does it go? Only in the AdBlue tank, which has its own filler, usually with a blue cap; never pour it into the fuel tank, and never put fuel additives in the AdBlue.
• How often do I add it? At every AdBlue refill, sized to the tank: 125ml for a tank of 10 to 20 litres, the whole bottle for one of 45 to 75 litres.
• What does it help prevent? AdBlue crystals in the tank, pump, lines or injector are a common cause of AdBlue warnings and SCR faults, and keeping them away avoids costly repairs and downtime.

Which one?

For the exhaust side of the same system, Wynns CV Dpf Regen And Nox Sensor Protector 1 Litre (W28090) helps keep NOx sensors free of AdBlue contamination.
