It is primarily utilized in heavy-duty applications like Workhorse W22 and W24 motorhomes and P42, W42, and W62 step vans.\u003cbr\u003eBecause RVs and commercial step vans carry significant weight, this clutch utilizes a specific heavy-duty thermal engagement profile tailored to managing the immense heat generated under heavy loads or when climbing steep grades.\u003cbr\u003e\u003cbr\u003eTechnical Specifications \u0026amp; Engagement Rules\u003cbr\u003e\u003cbr\u003e• Air-Temperature Activated: The viscous coupling engages based on the temperature of the air passing through the radiator, not the internal engine coolant temperature.\u003cbr\u003e• Engagement Profile: It begins initial engagement at approximately 178°F (81°C) air temperature past the hub, and achieves full engagement at 201°F (94°C). On the dashboard, you will typically notice the famous \"fan roar\" locking in when engine coolant temperatures reach 205°F to 210°F.\u003cbr\u003e• Torque Specs: Fan-to-clutch bolts should be torqued to 17 ft-lbs, and the clutch-to-water pump hub interface torqued to 41 ft-lbs.\u003cbr\u003e• Compatibility: It is designed to match the 20-inch fan blade (Part # W8002568). It supersedes the older kit number W0007657.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Workhorse W8002567 Engine Cooling Fan Clutch Drive","offers":[{"title":"Default Title","offer_id":68122732757224,"sku":"Container A H2-5","price":120.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/6622\/7432\/files\/miPmwW2C_0.jpg?v=1793889100","url":"https:\/\/marketfrog.ca\/products\/workhorse-w8002567-engine-cooling-fan-clutch-drive","provider":"Market Frog","version":"1.0","type":"link"}
