Engines & parts

Volvo Penta 2001 / 2002 / 2003 / 2003T parts: limited

Factory standard engine — you entered “Volvo Penta 2002”

Parts are available through Volvo Penta but owners consider them unique and overpriced (e.g., 2003T turbo, aluminum heat exchanger and oil cooler each quoted in the $1,700–3,000 range). Workarounds include converting the 2003T cooling system to aftermarket cupronickel heat exchanger and oil cooler, using the common aftermarket turbo, and cross-referencing some Perkins parts. Parts4Engines stocks aftermarket service parts.

Common problems (3)

Aluminum oil cooler and heat exchanger failures (2003T) cooling
The aluminum oil cooler and heat exchanger are the usual first failures, and genuine replacements are very expensive, so some owners convert to aftermarket coolers or repower.

Carboned exhaust elbow and turbo from low-load running exhaust
Long periods at low rpm carbon up the elbow and the 2003T turbo; the turbo can also be wrecked if it ingests the intake silencer foam.
