Frequently Asked Questions
Q: How do I confirm Crusader 22606 fits my engine?
A: The 22606 hose kit is for Crusader 454 cubic inch (7.4L) marine engines equipped with fresh water cooling (FWC). Locate your Crusader engine model and serial number on the engine ID tag and contact us by email, text, or live chat to confirm 22606 is the correct kit before ordering.
Q: What is fresh water cooling (FWC) and how is it different from raw water cooling?
A: Fresh water cooling (also called closed cooling) uses a heat exchanger to circulate a clean 50/50 antifreeze/water mixture through the engine block, similar to an automotive cooling system. Raw water from the lake or ocean only passes through the heat exchanger, not the engine. FWC systems significantly reduce internal corrosion and extend engine life compared to raw water cooling.
Q: Are these hoses pre-formed or can they be cut to length?
A: The 22606 kit contains pre-formed (molded) hoses that are shaped to fit the specific routing of the Crusader 454 FWC system. They are not cut-to-length hoses.
Q: What coolant should I use when refilling after replacing the hoses?
A: Crusader specifies DEX-COOL extended life coolant (pink/orange) mixed 50/50 with water for closed fresh water cooling systems. Do not mix DEX-COOL with conventional green silicated coolant. Do not exceed a 50% coolant concentration as this can cause overheating.
Q: Why is this kit not eligible for free shipping?
A: Hose kits of this size and weight ship via carrier freight. Shipping charges will be calculated at checkout. Contact us by email, text, or live chat if you have questions about shipping to your location before ordering.
