For Passenger Cars + Light Commercial Vehicles

Fort Exhaust Crystal Preventer has been specifically formulated to prevent blockages and damage to theSelective Catalytic Reduction (SCR) system and componentscaused by the formation of crystals.

The formation of crystals in the SCR system can occur in the Diesel Exhaust Fluid (AdBlue) tank, level sensor, fluid pump, AdBlue injector and exhaust system, including the mixer and the SCR catalyst.

Crystals form in the exhaust system when the exhaust gas temperatures are low, a result of driving styles, road restriction challenges such asregular travel in low speed zonesand incomplete combustion.

Fort Exhaust Crystal Preventer dissolves crystals that have formed in the exhaust fluid tank, affecting the function of the level sensor and fluid pump.

Use Fort Exhaust Crystal Preventer on every service and when topping up the vehicles Diesel Exhaust Fluid (AdBlue) to prevent the build-up of crystals forming in the Selective Catalytic Reduction (SCR) system.

• Keeps the complete SCR system free from crystals
• Prevents crystals from forming on the following components and ensures they function correctly:
• Fluid Tank
• Level Sensor
• Fluid Pump
• AdBlue Injector
• Exhaust SCR Mixer
• SCR Catalyst
• NOx Trap

BEST PRACTICE
At every service, add Fort Exhaust Crystal Preventer to the AdBlue tank. Clean the diesel fuel and oil systems using Fort Advanced Formula Diesel Treatment and Fort Advanced Formula Motor Flush to restore performance and importantly, to maintain exhaust gas temperatures.

In between services, when refilling the AdBlue tank, add Fort Exhaust Crystal Preventer to the AdBlue tank.
