Keep cooled charge air moving from the intercooler back to the engine with the Gates Intercooler Hose 29003. It fits as a direct-fit replacement on the cold side — the run from the intercooler to the engine — for the 2002-2006 Freightliner MT45 and the 2004 Freightliner MT55.
Over time a charge-air hose can harden, crack, or split, and its clamped connections can loosen and leak. Signs this hose may need replacing include visible cracking or softening, an audible boost leak, or reduced engine performance; if a failed intercooler hose is the cause, this replaces it.
