Vehicle Engine Oil Cooler, the core heat dissipation component of the engine lubrication system, with key information as follows:

Core Function

Reduces oil temperature through heat exchange between coolant and engine oil: High-temperature oil flows through internal channels of the cooler, transferring heat to external coolant to maintain oil temperature within an optimal range (typically 70-90°C), ensuring lubrication performance (preventing high-temperature oxidation and viscosity loss).

Compatible Models and Engines

Compatible Engines: Weichai WP10/WP12, Sinotruk MC11/MC13, and other heavy-duty diesel engines

Compatible Models: Sinotruk Howo, Sandaika, Shaanxi Delong, and other heavy-duty trucks

Product Features

Structure Type: Plate-fin / Shell-and-tube cooler. The illustrated aluminum plate-fin design offers high heat dissipation efficiency and compact dimensions, accommodating tight engine installation spaces.

Connection Method: Connects to engine oil inlet/outlet lines at both ends. Mounted via shell bolts to the engine block or oil filter housing, operating in parallel with the coolant circulation system.

Material & Reliability: Constructed from corrosion-resistant aluminum alloy with excellent thermal conductivity. Internal channel design ensures thorough oil-coolant contact while integrated sealing structures prevent cross-contamination between fluids.

Maintenance Guidelines: Regularly inspect for cooler blockage (detectable via abnormal oil pressure/temperature readings). If coolant contamination (emulsification) appears in engine oil, replace cooler seals or the entire assembly.
