OE Standard Size Engine Oil Cooler High-Density Stacked Aluminum Core Oil Cooler Radiator with High-Temperature Resistant Rubber Gaskets

This Engine Oil Cooler Radiator with OE numbers 06K117021B and 06K117021G is an efficient aftermarket cooling component compatible with Volkswagen Passat, Jetta, Golf, and Audi A4L, A6L, Q5 EA888 engines. It is manufactured strictly to OEM specifications to ensure accurate fitment and stable oil temperature control for the engine lubrication system.

As a key heat exchanger, this oil cooler circulates coolant to take away excess heat from engine oil. It keeps the oil within the optimal working temperature range, maintaining proper oil viscosity, reducing thermal degradation and preventing oil coking. A failed oil cooler often leads to engine oil overheating, oil emulsification, oil and coolant mixing, leakage and rising engine temperature, which will cause serious wear and damage to internal engine parts if not replaced promptly.

It adopts high-density stacked aluminum core structure with outstanding heat exchange efficiency and anti-corrosion performance. The matched sealing gaskets are made of high-temperature resistant rubber, effectively isolating oil and coolant circuits to avoid cross-leakage. Every unit undergoes strict pressure and leakage testing before delivery to guarantee reliable sealing performance under long-time vibration and temperature cycling.

It supports direct bolt-on installation without extra modification, saving labor time for repair technicians. It is a cost-effective and dependable cooling spare part for auto repair shops, spare parts wholesalers and aftermarket retailers, helping stabilize engine oil temperature and protect the lubrication system for these popular VAG turbo models.
