hey can please some1 tell me how to do it so my ford doesnt break down or anything when the heat does start coming in melbourne?:)

My suggestions:

Engine cold, remove radiator drain plug (or if no drain plug) bottom hose and thermostat (so coolant will be removed from head and block). Make sure heater tap is full on to get water out of heater. Remove radiator and flush by running water fromn hose in inlet and outlet.

Or pay a shop to do it as they have the gear to flush under pressure.

Use Castrol R.

how much to get it professionly done? Also would removing the radiator drain plug remove coolant from inside the engine block as well or is there a seperate plug? what do you mean by heater tap? you mean turn on the car and turn the heater on?

thanks

I would not use the hot engine running approach some suggest; many many moons ago I was using this method and the engine stalled, head cracked, bores filled with H2O rods bent.

BTW take the opportunity to fit a new thermostat. They become less effective with age slowing warm up time, increasing fuel usage and accelerating engine wear.

so do you turn on the heater to full by just puting the car in accesories?

thanks

Yes; just turn the heater to full on. In addition to perhaps having a drain plug at the bottom of the radiator you may also have a water drain plug in the block. What motor and year is it?

Aussiblue · 02-04-2002, 07:26

If you don't remove the thermostat some water will be left in the block.
