Doghouse Style Fan Shroud, With Heating Ducts, Black

Doghouse Style Fan Shroud with Heating Ducts - Black

Optimize your engine's cooling efficiency with the Doghouse Style Fan Shroud from Appletree Auto. This shroud is the "gold standard" for high-performance and stock 1600cc based engines, specifically designed to accommodate the external "doghouse" oil cooler. Unlike early-style shrouds that blow hot oil-cooler air back onto the cylinders, the doghouse design exhausts that heat out the back of the engine through specialized tinware. This results in significantly lower head temperatures and increased engine longevity.

Finished in a clean, durable semi-gloss black, this shroud includes integrated heater ducts to maintain your vehicle's cabin heating and defrosting capabilities. It is constructed from heavy-gauge steel for a precise fit and superior vibration resistance. Whether you are building a fresh long block or upgrading your current cooling system, this shroud from Appletree Auto provides the professional look and thermal management your air-cooled Volkswagen requires for modern driving conditions.

Product Fitment & Compatibility

This shroud is designed for use on 1300cc, 1500cc, and 1600cc Air-Cooled Type 1 based engines. It must be used with a doghouse-style oil cooler and the corresponding exhaust tinware.

Tech Tips & Installation Advice

• Required Components: To function correctly, this shroud requires the "Doghouse" oil cooler, the oil cooler adapter (if converting from an early case), and the specialized rear exhaust tinware. Without the proper tinware, the air will not be directed correctly, leading to potential overheating.
• Check Fan Clearance: Before final assembly, mount your fan to the alternator/generator and spin it by hand within the shroud. There should be a small, uniform gap around the perimeter of the fan. If the fan rubs, you may need to adjust the backing plate or add/remove shims to center the fan perfectly.
• Sealing the Tin: Air-cooled engines rely on air pressure. Ensure all "over-cylinder" tin and rubber seals are in good condition. Any gaps between the shroud and the tinware will allow pressurized cooling air to escape, reducing the cooling efficiency to your cylinders and heads.
• Spark Plug Wire Routing: Use high-quality rubber grommets where the spark plug wires pass through the shroud. This prevents the metal edges of the shroud from chafing the wires, which can cause arcing and engine misfires.
