Here we have a classic case of terrible things to come if nothing is done soon. This is a Volvo MD40 series engine and the after-cooler is "blooming" - this unit needs to come apart and be serviced (cleaned and pressure tested). if it fails the pressure test it will need a new core. After-coolers are one of those parts we don't repair - It is a critical part and failure is usually catastrophic. Call us at West Coast Marine Diesel and we can come down and assess your cooling system.
