T3 Vanagon Deluxe Engine Oil Cooler Kit


Vanistan engine oil cooler kits put a lid on high engine oil temperatures and put an end to flickering warning lights and terrifying buzzers. Keeping temps below 230ºF extends the life of your engine oil, too, so you can get optimal service for the maximum mileage, saving money and resources while protecting your engine for the long run.


Our oil cooler assemblies install neatly inside the Vanagon’s right-rear D-pillar box cavity, so the air that flows naturally down the rear body pillar ducts can be used for cooling the engine oil. Closely-fitted mounting panels channel airflow thru a top-quality oil-to-air heat exchanger.


Oil flow to the cooler is controlled by a Mocal sandwich adapter unit with thermostatic bypass valve, so full engine warmup is never delayed and oil is never overcooled.


Both kits allow the engine to continue to get its intake air from the D-pillar duct, where the air is cooler and cleaner.


The Basic Oil Cooler Kit is for Vanagons driven mainly on-road. Vehicle speed creates all the cooling airflow your waterboxer engine needs.


Installation is easy in about 2 hours using common tools.
