Help needed with 08 Allegro Bay 35TSB with ISB 340 Cummins Water Pump Replacement

Does anyone know if the water pump access on the ISB 340 Front mount diesel on a 2008 Allegro Bay 35TSB would be from underneath between engine and radiator or would one have to come in from the access panels in the floor along side the drivers seat from the top down to replace the water pump?

Welcome to iRV2

I'd say easiest from underneath ; water pump is in the lower 1/2 of the front of the engine.

Remove serpentine belt and tensioner , for best access.

Having said that ; reinstalling the serpentine belt may require access from both top and bottom .
