Parts Desk Insight
143°F thermostats are specific to raw water cooled Crusader/PCM setups. Installing a higher temp thermostat (160°–170°) in these systems can lead to overheating, especially in warmer water or restricted flow conditions. This is the correct spec for older Crusader engines designed to run cooler.
