Volvo FH4/FM/FMX AdBlue Tank 22116321 22193761 RH Euro 6 Used Diesel Exhaust Fluid (DEF) Systems

This is an original Volvo AdBlue (DEF / urea) tank, part number 22116321, removed from a running Volvo FH4 Euro 6 truck and checked for leaks and damage before dismantling. The tank is used but in good working condition, with normal signs of use on the plastic body only.

The 22116321 tank is part of the SCR (Selective Catalytic Reduction) exhaust aftertreatment system. It stores AdBlue/DEF solution and supplies it to the dosing module, helping the truck meet Euro 6 emissions standards by reducing NOx in the exhaust. Volvo AdBlue tanks are plastic, electrically heated and available in several sizes; this particular variant is typically a ~65-litre tank, used on heavy-duty tractors and chassis.

This tank is commonly fitted to:
• Volvo FH4 (2013-onwards) Euro 6 truck tractors and chassis.
• Also used across the Volvo FH, FM, FMX 4-series Euro 6 range where the same part number is specified.

Cross-reference / replacement numbers (for guidance only):
22116321, 22193761, 21732650, 23292710, 23251739, 21232204, 22203920, 21995144 – various listings show these as interchangeable AdBlue tank assemblies for Volvo FH Euro 6 trucks.

Construction details: the body is a rotomoulded polyethylene (PE) tank, marked “BODY ITALY >PE<”, designed to resist corrosion from AdBlue and withstand heavy-duty use on the chassis. Mounting points, threaded inserts and ports for the level sender, pump/heater module and lines are intact. Your item is sold as tank body only – no pump, level sensor, wiring or mounting brackets are included and should be transferred from your old tank or sourced separately.

Installation notes:
• Professional fitting is recommended – the tank must be securely mounted in the original position and connected to the SCR pump module, return lines and breather hoses according to Volvo workshop procedures.
• After installation, the AdBlue system should be filled with fresh, clean DEF and the SCR system checked for leaks and correct operation; in most cases no coding or programming is required for the tank itself, but any electrical modules or sensors you reuse or replace should be checked with a diagnostic tool and system faults cleared.
• Always match the part number (and cross numbers above) and compare the shape, mounting points and port locations with your original tank. Compatibility based on VIN or registration alone is not guaranteed; the buyer is responsible for confirming fitment.

This genuine Volvo AdBlue tank is an ideal replacement if your existing reservoir is cracked, leaking or heavily contaminated. Replacing a damaged tank helps prevent SCR faults, derating and dashboard warnings, and supports reliable emission control on your Euro 6 Volvo FH/FM/FMX.
