Automotive RepairDiagnostics & Troubleshooting4HighOwner$ implied

A vehicle owner with a coolant leak at the heater core supply line connection on an older high-mileage truck needs to identify the leaking part and find a repair method that avoids replacing the expensive intake manifold, which he has never done before.

Existing solutions are either too expensive and complex (intake manifold replacement) or unreliable (RTV patch), and there is no easy way to access or replace just the gasket at the heater core connection without removing the entire intake manifold.
