⚙️ Key Features

• Engine type: D13 or D16 turbocharged marine diesel

🔌 Function

Forms the specified coolant and seawater flow passages in the plate heat exchanger while keeping both fluids separated.

⚠️ Common Signs of Failure

• Coolant and seawater cross-contamination
• Pitting or perforation
• External leakage from the plate stack
• Distortion preventing gasket sealing

🛠️ Service Notes

• Treat it as part of the cooling circuit: check both sealing faces are clean and true, renew every gasket and O-ring, and never refit a distorted or corroded plate
• Look through the passages for scale, silt and corrosion while the plate is off and flush them clear; a partly blocked plate will not shed heat even though it looks sound
• Fit the fasteners evenly in stages, in the sequence and to the figures in the workshop manual for your engine, so the plate is not pulled out of flat
• Fill and vent the system properly, then run the engine to temperature and check the joints for seepage
