- Twin Caterpiller 3208 (375 HP)
Hi, just took a 10 day trip in our 1989 SeaRay 440 Aft Cabin with twin Caterpillar 3208 turbo engines (375 HP). Before our trip I topped off the coolant level in each engines reservoir to “Full, Cold”. Every morning when I routinely checked fluid levels and belt tensions the coolant reservoirs on both engines were at that same level (Full, Cold). On Day 9 this changed and both coolant levels were down about a quart, and remained so after Day 10. What would cause this to happen? Is this cause for concern?
