flushing

Right. Having checked every possible reason for my 1330 running warmer than desired i've decided to flush the system. The radiator is new so i was thinking of removing it and simply flush the block and head. My question is:

1) which way do i flush it? (remove thermostat?, reverse flush?, open drain plug at rear?) 2)Any effective products out there to remove some of the rust buld up in the cooloant jacket? Would the water pump prevent any significant sludge from escaping the system if i reverse flushed it?

In other words if anybody has done this before and please enlighten me :-)

Thanks

Remove the thermostat. Remove any drain plugs. Disconnect the heater. Flush every way possible with as much water as your hose will manage. The water pump is open enough that any sludge will go straight through it. Flush the heater separately. I've tried a few chemical flushing agents but never found them very effective. Once you have got the system working, don't forget to fill with antifreeze. It's inhibitor will prevent any more corrosion.
