Before and after Barnacle Flush
Marine Cooling Maintenance ensures the proper function of sea water cooled heat exchangers, intercoolers/aftercoolers and gear box coolers. In some cases also the power steering cooler, fuel cooler, and engine oil cooler. We use an environmentally safe solution that does not harm metal or rubber seals to flush your sea water system of marine growth and ensure proper water flow to your engine.
Without proper water flow, your engine loses cooling efficiency, resulting in engine overheating. Over time this can lead to significant damage costing thousands of dollars in mechanical service and downtime. Our service is non-invasive and a fraction of the cost of traditional marine mechanical service and we keep your downtime to a minimum. Here’s what we do…
- Borescope: Heat Exchanger, Cooler (Trans) other systems when Zinc and or visual openings are accessible and possible.
- Pressure test Heat Exchanger for loss of pressure and leaks. If an expansion tank (recovery bottle) is in place, check for proper connections, obstructions and for leaks.
- Check Coolant level, color and test for effectiveness; check overflow level in the tank.
- Visual and Borescope Raw Water Pump Impeller. Checking for color change of the original color black impeller; Flexibility, chips, cracks, and Borescope down the fins.
- Check Sea Cock Valve for operational and functional. Note: A Sea Cock Valve in a closed position can still allow for seawater seepage if the valve is compromised.
- Check Sea Strainer for grass build-up and clarity of cylinder.
- Check Zincs for wear and leaks.
- Check all Hoses and Hose Clamps and inspect for double clamps where necessary.
- Start Engines checking for issues that could prevent doing a flush. While the engine is running, check the hull outflow exhaust/water stream and color of smoke if any.
