The Fuel‑Fired Heater System Controller is the intelligent brain of the heating system, managing combustion timing, fuel metering, and fan speed. It features a built‑in diagnostic interface and temperature sensors that automatically adjust the heat output to maintain the desired cabin or engine temperature, ensuring optimal efficiency and safety.
The Plateau Component Additional Harness is a dedicated wiring extension designed for high‑altitude operation. It connects the heater controller to the altitude sensor, compensating for reduced oxygen levels to maintain proper combustion. This harness is essential for trucks operating above 3000 metres.
This power harness delivers high‑current supply directly from the battery to the heater unit, with heavy‑gauge cables and a waterproof fuse holder. It is pre‑terminated with ring terminals and a sealed connector, ensuring a reliable, low‑resistance path for the substantial current required during start‑up.
The Fuel Pump Chassis Wiring Harness routes control signals to the fuel dosing pump, ensuring precise fuel delivery to the heater. It is protected by a flexible, abrasion‑resistant loom and is routed along the chassis rail, away from heat sources and moving parts.
The Rear Cover Plate is a powder‑coated steel panel that protects the heater’s combustion chamber and exhaust outlet from road debris and water splash. It is designed to fit the C7H chassis perfectly, with pre‑drilled holes for easy installation and maintenance access.
This high‑precision sensor continuously monitors the ambient air pressure and temperature, adjusting the fuel‑air mixture for stable combustion at high altitudes. It is a critical component for reliable heater operation in mountainous regions, preventing flameouts and sooting.
This harness connects the new‑generation heater controller to the cab’s power and control network, enabling driver‑adjustable settings and diagnostic feedback via the dashboard. It is engineered for the revised controller interface and includes a CAN bus connection for integration with the vehicle’s electronic system.
Our Fuel-Fired Heater is manufactured to Sinotruk’s exacting standards, ensuring every component fits and functions as intended. The controller, harnesses, and sensors are calibrated for the C7H’s electrical architecture, delivering seamless integration and reliable operation.
The Fuel-Fired Heater quickly raises engine coolant temperature, reducing oil viscosity and enabling easier starts. It also provides cabin heating without running the main engine, saving fuel and reducing emissions during extended idling.
We supply all necessary wiring, controllers, sensors, and mounting plates for a full installation. The included harnesses are pre‑terminated and labelled, simplifying the replacement process and ensuring correct routing.
All components are built to withstand the harsh under‑chassis environment, with corrosion‑resistant coatings, sealed connectors, and high‑temperature insulation. The Fuel-Fired Heater is designed for long‑term reliability in the most demanding conditions.
The Fuel-Fired Heater is an essential system for heavy trucks operating in cold climates. It uses diesel fuel from the vehicle’s tank to generate heat, which is then transferred to the engine coolant and cabin heater core, significantly reducing warm‑up time and improving driver comfort.
The controller unit is designed with a user‑friendly interface, allowing drivers to set a timer or pre‑heat the engine remotely. Its advanced logic ensures that the heater only operates when necessary, conserving fuel and battery power.
The plateau‑specific components are a standout feature, making this system ideal for trucks that regularly traverse high mountain passes. The additional harness and altitude sensor automatically compensate for thinner air, maintaining a clean, efficient burn that prevents soot accumulation and extends the heater’s service life.
Installation is straightforward with the complete harness set. The power harness connects directly to the battery positive and negative terminals, while the control harness interfaces with the cab’s wiring. All connectors are keyed and colour‑coded to prevent misconnection.
A common issue with aging heating systems is corroded wiring or failed sensors, leading to intermittent operation or complete failure. Replacing the entire system with our genuine Fuel-Fired Heater kit restores full functionality and eliminates the guesswork of diagnosing multiple faults.
The rear cover plate is not merely a protective shield; it also incorporates acoustic damping material to reduce the characteristic ticking noise of the fuel pump, making the system more pleasant for drivers and bystanders alike.
We recommend that the Fuel-Fired Heater be tested before the onset of winter. Using a diagnostic tool, the controller’s error memory can be checked, and the heater can be fired up to verify that all components are functioning correctly.
For fleet operators, standardising on this genuine Fuel-Fired Heater ensures that all trucks have the same level of cold‑start capability and driver comfort. It also simplifies spare parts management and reduces the likelihood of field failures.
The new controller version features a more robust power supply that handles voltage fluctuations better, and the cab bottom wiring harness has been improved with higher gauge wires to reduce resistance and heat generation.
