2.5L 4d56 turbo diesel Maintenance Routine

l300 starwagon / occasional l400 (1986-1999)

The 4D56 is an efficient, reliable diesel engine. To match this reliability and prepare the 4D56 for long travels and many miles on and off-road, Nomadic Van applies a 100+ point maintenance routine to inspect and prepare your engine.

The Nomadic Maintenance Routine is perfectly thorough on the 4D56 engine. We replace every hose, gasket and seal that is accessible with out taking the front case off. If we discover any issues with the fuel injectors, injection pump or seals we will replace them with professionally rebuilt parts before they leave our shop. Needless to say once the 4D56 is properly maintained and tuned up she can handle the gnarly conditions and adventures!
