Sourced directly from Wacker Neuson's parts catalog under part number 5000179846, this cap maintains the closed-loop coolant circuit that allows these hydronic and indirect-fired heaters to operate safely under thermal load.\u003c\/p\u003e\n\n\u003cp\u003eOn the HI1000 and HI1000DGM indirect-fired heaters, the radiator cap is positioned within the engine components section of the cooling circuit. A failed or degraded radiator cap can result in coolant loss, pressure drops in the heating loop, and overheating of the engine assembly. Replacing a worn cap with a genuine OEM part ensures the cooling system holds its rated pressure and functions as designed.\u003c\/p\u003e\n\n\u003cp\u003eThe E3000 ground heater, rated at 6kW, also relies on this cap as part of its engine cooling components. This part is confirmed fitment for the HI1000DGM variant listed under Wacker Neuson assembly number 5100049276.\u003c\/p\u003e\n\n\u003cp\u003eCompatible models include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eE3000\u003c\/li\u003e\n\u003cli\u003eHI1000\u003c\/li\u003e\n\u003cli\u003eHI1000DGM\u003c\/li\u003e\n\u003cli\u003eHI1000DGM (5100049276)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eGenuine Wacker Neuson OEM part, sold by an authorized dealer.\u003c\/p\u003e","brand":"Wacker Neuson","offers":[{"title":"Default Title","offer_id":43397610111024,"sku":"WACKER-5000179846","price":81.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6574\/7248\/files\/5000179846.jpg?v=1784040344","url":"https:\/\/cce-industries.com\/products\/wacker-neuson-radiator-cap-5000179846-for-air-hydronic-heaters","provider":"CCE Industries","version":"1.0","type":"link"}
