ST162 radiator fits a treat.
The driver's side bottom mount fits the stock sprinter mount (if you use the Celica rubber). The passenger side needs a bolted lower mount (from AE82 or ST162 or something similar) to be added. I managed to set it up so that I could still refit the original radiator if required too.
Lower hose fits easy. Top hose needs some messing around.
Works well with the stock ST162 thermos.
