About the only way that I know of would be to raise the hood, pull the heater hoses off at the fire wall, and run water from a hose pipe into both sides of the tubes poking through. Basically it is a little radiator and you are running water through it at more volume and pressure.
hope this helps.

Actually you can buy [at least used to] a flush kit from Prestone that has a tee fitting into heater hose that you can attach a garden hose to and a piece that fits into the radiator cap opening. Then you can actually reverse the flow of water through the heater core and radiator. I found that if you shut water flow off and on by bending the hose you can really shake some crud loose and flush it out.
