Included scope
- AdBlue / DEF / urea / reductant tank level sensors
- SCR tank level-temperature modules and quality-level headers
- OE/photo confirmation for commercial vehicle and off-highway applications
Separated scope
- Coolant, washer fluid, fuel, oil and hydraulic tank sensors
- BEDIA, marine, industrial and general reed-switch level sensors
AdBlue & DEF Level Sensors, Quality Headers & Tank Sending Units
Comprehensive OEM replacement directory and direct factory wholesale sourcing for Diesel Exhaust Fluid (DEF), AdBlue, and urea tank sensors. Supporting North American Class 8 heavy trucks (Freightliner Cascadia, Kenworth T680, Peterbilt 579, International LT, Volvo VNL, Mack Anthem), European Euro 5/6 fleets (Mercedes Actros, Scania R/S, DAF XF, MAN TGX, IVECO S-Way), Japanese commercial trucks (Hino, Isuzu), and heavy diesel pickups (RAM 1500/2500/3500, Ford Super Duty, GM Duramax). All sensors manufactured under strict IATF 16949 quality standards with 100% bench tested level, temperature, heating and ultrasonic urea quality (QLS) functions.
Multi-Function DEF Header Sensor Anatomy
Modern EPA10/EPA17/EPA21 and Euro 6 SCR systems require multi-function DEF header units to prevent catastrophic engine derates. SHR Autoparts headers integrate 4 vital sensing and conditioning circuits into one assembly:
- Continuous Reed-Switch Level Float: Accurate resistance ladder fluid level monitoring across 0% to 100% capacity.
- Ultrasonic Urea Concentration Sensor (QLS): Real-time 32.5% DEF purity verification to prevent SPN 4364 / SPN 3582 poor fluid derates.
- Integrated NTC Temperature Sensor: Accurate DEF fluid temperature monitoring for ECU freeze protection.
- Engine Coolant Heater Coil: Dual stainless coolant tubes designed to thaw frozen DEF fluid within 20 minutes under -40°C ambient.

DEF / AdBlue Fitment Verification Checklist
Because diesel exhaust fluid tank headers integrate mechanical pickup, coolant thawing, and electronic sensing, always confirm these 4 specifications before ordering:
- OE / OEM Part Number: Cross-reference the stamped part number on your header flange or harness tag (e.g.
04-35163-000,4378050,Q21-6170-007K1T). - Tank Depth & Sensor Tube Length: Available in 280 mm (11-inch), 370 mm, 449 mm, 520 mm and custom lengths to match 6 to 30 gallon DEF tanks.
- Flange Mounting Style: Twist-lock bayonet collar (PACCAR/Shaw), SAE standard 5-bolt pattern, or threaded ring collar.
- Connector Pinout & Voltage: Confirm 4-pin, 6-pin, or 8-pin harness connector and CAN-bus protocol (SAE J1939).
Have an engine derate code or damaged DEF header? Take a photo of your original sensor label and connector and our technical engineering team will verify exact fitment within 2 hours.

Review AdBlue level sensor function, common problems, and replacement basics for SCR tank sourcing.
AdBlue level sensor selection checklist
AdBlue tank monitoring parts should be checked against tank depth, connector, heating function, and OE reference before sourcing.
Selection checklist
- OE number or tank sensor module photo
- Tank depth / installation length if known
- Connector, heating and temperature function details
- Vehicle or equipment application
Common symptoms
- Wrong AdBlue level reading
- SCR tank sensor fault code
- Low level warning despite correct fill
- Heater / temperature signal issue
What to send for RFQ
- Sensor module photo and OE number
- Tank / vehicle application
- Quantity and market requirement
Buyer FAQ
Why does tank depth matter for AdBlue level sensors?
Different tank modules can share similar connectors but use different length, heating, and sensing configurations.
Can SHR Autoparts check AdBlue level sensor compatibility?
Yes. Send the module label, connector photo, and vehicle application for cross-reference support.
