⚠️ Common Signs of Failure

• Coolant loss with no external leak, or oil traces in the coolant
• Tube stack silted, scaled or blocked
• Salt crusting, pitting or perforation on the raw water side
• End cover joints weeping

🛠️ Service Notes

• Three heat exchangers sit in this group at very different sizes - this one at 23.587 kg, 3828469 at 14.22 kg and 3828574 at 35.38 kg - so check the fitment and supersession chain rather than picking by appearance
• Renew the end cover gaskets, seals and any sacrificial anode with it, and check the raw water pump impeller for the debris that blocked the old stack
• At 23.587 kg this needs lifting support rather than being handled by hand
