Understanding The Crusader 454 Cooling System A Visual Guide I just picked up a new to me boat with twin crusader 454 350hp motors. it has a closed fwc system and raw water only sees the raw water pump, u coolers, heat exchanger, risers and elbows. it seems my manifolds are running really hot, which are antifreeze cooled. manifolds read up to 235 at the dock at a fast idle. The crusader engine electronic system is programmed to control the engine alarm system. this system utilizes an indicator lamp (“mil” or “check engine”) and or an optional audible alarm to warn the operator of possible engine problems. the alarm circuit has a “self” checking feature programmed into the system.
Crusader 454 Cooling System Diagram The cooling system of a crusader 454 engine consists of several components that work together to regulate the engine’s temperature. one of the main components is the water pump, which is responsible for circulating coolant throughout the engine. the water pump is driven by the engine’s serpentine belt and pumps coolant from the radiator. Fellow boaters, i have a 1996 caver santego with x2 454 mpi crusader engines that is currently raw water cooled and would like to convert these to fresh water cooled. the reasons for wanting to convert are for easy of winterizing and possibly moving from the finger lakes region to the east.
