Copper housings on these engines tend to pit and perforate after many years of service, particularly if incorrect coolant or inhibitor levels allowed the coolant chemistry to degrade. Replacing the housing while the system is already drained for a thermostat or heat exchanger service is the most efficient approach.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon issues:\u003c\/strong\u003e The most frequent ordering mistake is not confirming the heat-exchanger mounting location. Crusader used both front-mounted and rear-mounted heat exchangers on similar engine families, and the thermostat housings are not interchangeable between those configurations. Always confirm the rear-mounted layout from the engine parts diagram before ordering. The second issue is replacing only the housing without inspecting the attaching hose (98204) and clamps (20868) — a deteriorated hose or loose clamp at the housing connection is a common source of repeat coolant leaks after housing replacement.\u003c\/p\u003e","brand":"CRU","offers":[{"title":"Default Title","offer_id":43563780505636,"sku":"98202","price":344.89,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/3c7cdbfb-17a1-4e58-bea8-9d4cb3e4aa7f.png?v=1788825633","url":"https:\/\/marisolmarine.com\/products\/crusader-copper-thermostat-housing-oem-98202","provider":"Marisol Marine Company","version":"1.0","type":"link"}
