The J360I-I307IOOH water pump features a precision‑machined cast iron housing and a dynamically balanced impeller that ensures efficient coolant flow with minimal cavitation. The impeller is designed to provide the correct flow rate for Howo diesel engines, maintaining optimal temperature even under heavy load. The pump includes a high‑capacity sealed bearing that is pre‑lubricated and maintenance‑free, eliminating the need for periodic greasing. The shaft seal is made from advanced carbon/ceramic materials, providing leak‑free operation for thousands of hours.
Every J360I-I307IOOH water pump undergoes rigorous testing before leaving the factory. The housing is pressure‑tested to ensure no porosity or casting defects. The bearing and seal assembly are tested for smooth rotation and leak prevention. The pump flange is machined to exacting tolerances to guarantee a perfect seal with the engine block. This attention to detail ensures that the water pump performs flawlessly in the harsh environment of a heavy‑duty diesel engine.

The J360I-I307IOOH water pump is a direct OEM replacement for the coolant pumps used in a wide range of SINOTRUK HOWO engines, including the WD615 series (Euro‑2 to Euro‑5), the MC11 and MC13 engines found in T7H and C7H models, as well as the D10 engines. It circulates coolant through the engine block, cylinder head, radiator, and the heating system for the cab. A properly functioning water pump is essential for maintaining the engine’s thermal balance, preventing hot spots, and ensuring efficient combustion.
In the context of the chassis, reliable engine cooling directly impacts the overall vehicle’s uptime. Water pump failure can lead to overheating, cylinder head cracking, and catastrophic engine damage, leaving a truck stranded and incurring costly repairs. By using the genuine J360I-I307IOOH part, you ensure that coolant flow remains within specifications, protecting not only the engine but also auxiliary systems such as the charge air cooler and transmission cooler (if engine‑driven). Fleet operators who prioritize genuine parts report significantly lower maintenance costs and extended engine life.
When replacing a water pump, always install a new thermostat and inspect the radiator and hoses for blockages. Use the correct coolant mixture to prevent corrosion and cavitation. Genuine J360I-I307IOOH pumps are engineered for the exact flow characteristics of Howo engines.
Correct installation of the J360I-I307IOOH water pump is critical to ensure proper cooling and long service life. Follow these steps:
Drain the cooling system and remove the radiator hoses, fan, and any belts that obstruct access. Clean the engine block mounting surface thoroughly, removing all old gasket material.
Place the new gasket (included) onto the pump flange. Position the pump onto the engine block and hand‑tighten the mounting bolts. Torque to the specification in the service manual (typically 45‑55 Nm) in a criss‑cross pattern.
Reinstall the fan and belts, adjusting tension correctly. Refill with the recommended coolant mixture. Run the engine and check for leaks, and verify that the coolant temperature stays within normal range.
A failing water pump can lead to overheating and serious engine damage. Common symptoms include coolant leaks from the weep hole, noisy bearing (grinding or chirping), loose impeller, and visible corrosion or rust on the pump housing. During routine maintenance, check for any signs of coolant seepage around the pump gasket or shaft seal. If the pump is more than 5 years old or has accumulated high mileage (over 500,000 km), proactive replacement is recommended. Any sign of bearing play or rough rotation indicates that replacement with a genuine J360I-I307IOOH is necessary.
Ignoring water pump wear can result in sudden loss of coolant, overheating, and potential cylinder head gasket failure or even cracked cylinder heads. Timely replacement with a genuine J360I-I307IOOH restores proper cooling and protects your investment.
Aftermarket water pumps often use inferior castings, substandard bearings, and poor‑quality seals that fail prematurely. They may have incorrect impeller designs, leading to insufficient coolant flow and overheating. The genuine J360I-I307IOOH is manufactured to the exact specifications of the original equipment, using high‑grade cast iron, precision‑balanced impellers, and heavy‑duty bearings that withstand the rigors of heavy‑duty operation. Each pump is tested for flow, pressure, and leak resistance before leaving the factory.
By choosing authentic SINOTRUK HOWO parts, you ensure that your engine receives the correct coolant flow at all times. This directly translates to longer engine life, reduced maintenance costs, and higher resale value. The Sinotruk howo parts catalog includes a full range of engine and chassis components engineered for maximum reliability.
To maximize the service life of your J360I-I307IOOH water pump, follow these best practices:
By adhering to these guidelines, you ensure that the J360I-I307IOOH pump performs optimally throughout its intended service interval.
The J360I-I307IOOH water pump is used across a wide range of Howo models: T7H, T5G, A7, and traditional Howo‑7 series. It fits engines with part numbers WD615.47, WD615.69, MC11.36, MC13.48, and D10.34. Always verify the engine serial number and the pump drive configuration (belt‑driven) to ensure proper fit.
Each J360I-I307IOOH is individually packaged with a protective coating to prevent corrosion during storage. The package includes a new gasket and the necessary mounting bolts (if applicable). For bulk orders, the pumps are supplied in sealed cartons with the OEM logo and batch traceability.
Production of the J360I-I307IOOH takes place in ISO/TS 16949 certified facilities, using precision CNC machining centers and in‑process gauging. Statistical process control ensures that dimensional variations are kept to a minimum, far exceeding the requirements of the original design. Every batch is accompanied by a material certificate and pressure test report, guaranteeing that the pumps delivered are identical to those fitted on new Howo trucks at the factory.
