Replacement Truck Coolant Level Sensor 2288684 2553061 for Scania NTG P G R S Series

Product Overview The 2288684 / 2553061 / 20553061 Truck Water Coolant Level Sensor is a premium commercial-grade fluid safety telemetry component engineered as a high-precision direct aftermarket replacement for Scania New Generation (NTG) heavy-duty trucks, line-haul tractors, and international mass transit coach networks. Mounted securely into the coolant expansion surge tank header assembly, this industrial-grade sensor continuously monitors the quantitative volume of the radiator anti-freeze mixture. It converts critical fluid depletion thresholds into instantaneous electronic signals for the central control infrastructure and dashboard cluster panel. Maintaining an uninterrupted diagnostic path through this telemetry loop is absolutely critical for triggering early low-coolant hazard chimes, enabling operators to avoid severe engine block boiling, rapid cylinder liner cavitation, and catastrophic thermal fracturing before sudden fluid loss stalls the fleet. Technical Specifications Primary Scania OE Reference Numbers: 2288684, 2553061, 20553061, 2 288 684, 2 553 061 Component Type: Heavy-Duty Commercial Vehicle Radiator Water Tank Expansion Surge Box Coolant Level Sensor Switch System Integration Architecture: Fully synchronized with Scania vehicle monitoring nodes, including N24R network diagnostic loops Installation Location: Snaps or screws directly into the dedicated receiver receptacle on the Coolant Expansion Reservoir Sump Sensing Element Core: Advanced magnetic proximity or conductive fluid matrix calibrated to eliminate zero-point tracking drift and false warnings caused by chassis sloshing Material Engineering: Corrosion-proof structural heavy polymer body mated with heat-stabilized, sealed connector pins to resist high cooling loop backpressure Condition: 100% Brand New Premium Aftermarket Replacement Vehicle fleet, Engine Family & Generation Compatibility This premium European commercial vehicle powertrain cooling monitor features extensive cross-reference application configurations across legendary classic and modern high-displacement Scania diesel platforms, multi-axle freight lines, and municipal transit frameworks: Truck Fleet Generation & Machinery Chassis System Application & Operational Fleet Fitment Scania New Truck Generation (NTG Platform – L-Series, P-Series, G-Series, R-Series, S-Series Heavy Fleet Truck Arrays) Primary radiator header box level monitoring and dashboard error tracking, matching modern high-torque inline 7L, 9L, 13L, and V16 heavy turbo engines (DC09, DC13, and massive DC16 V8 common-rail blocks) operating under rigorous international long-haul distribution networks. Scania Classic 4 Series Heavy Duty Trucks (Models P94, R94, P114, R114, P124, R124, R144, R164 Long-Haulers) Retrocompatible water tank capacity tracking and safety signal routing for classic mechanical or early electronic injection fleets working under heavy off-road construction and quarry tipper duties. Scania Advanced Bus & Coach Frameworks (4-Series, F-Series, K-Series, N-Series Trans-Continental Coaches) Multi-zone engine compartment coolant depletion diagnostics and electronic safety shutdown gate alignment, engineered to protect high-density public urban transit buses and luxury articulated tourist shuttles. Performance Benefits Eliminate False Dashboard Faults & Low-Water Chiming: Directly replaces brittle, internally shorted, or chemical-fouled legacy level sensors that trigger false dashboard “Coolant Level Low” hazard alarms, erratic gauge flickers, or unwarranted engine torque derates when fluid levels are actually completely fine. Advanced Multi-Axis Wave Slosh Filter: Internal diagnostic calibration buffers raw signal spikes caused by high-vibration engine blocks, heavy braking deceleration, or steep incline hill transitions, ensuring clean dynamic calculations. High Chemical & Coolant Compound Resilience: Heavy-duty industrial structural plastic design completely resists physical and chemical decay from high-temperature glycol anti-freeze solutions, rust inhibitors, and under-hood scaling. IP67 Rated Weather-Tight Connection Terminal: Molded polymer plug interface features internal moisture isolation blocks to secure low-voltage signal paths against engine bay condensation, road mud spray, and high-pressure chemical washdowns. Maintenance Tip: When installing the replacement 2288684 / 2553061 Scania coolant level sensor, ensure the vehicle is parked on an absolute level surface, the engine is fully shut down, and the cooling loop has cooled down entirely to avoid severe scalding hazards from pressurized hot anti-freeze fluid or steam. Carefully back off the expansion box cap slowly to release residual atmospheric pressure beforehand. Clean away all mud grit or atmospheric crust around the receiver block port before pulling the old sensor. Inspect the mounting seal face for any damage. Push the new sensor straight down into position to guarantee an absolute airtight seat (avoid forcing or twisting the plastic locking tabs unevenly), refill the radiator circuit to the proper cold fill line mark, verify there is no fluid weeping, and snap the original wiring harness clip securely home to restore your safety telemetry loop.
