Before refilling after a reservoir replacement, wipe the area clean and walk the full hydraulic circuit — hoses, pump seals, and cooler connections are the most common sources of slow leaks on D4 and D6 installations. Addressing the root cause during the same service saves another fluid loss and another diagnostic later.\u003c\/p\u003e","brand":"VOL","offers":[{"title":"Default Title","offer_id":43564036227108,"sku":"3863190","price":582.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/567d647f-4750-4e78-9e10-88c982b8d678.png?v=1789156325","url":"https:\/\/marisolmarine.com\/products\/volvo-861","provider":"Marisol Marine Company","version":"1.0","type":"link"}
