You can either flush it with the rest of the cooling system, or you can undo the hoses that go to the heater core, take a garden hose, and backflush it that way.

Those hoses are here (sorry for the crap quality, I took the pic on a cold winter's day using only my BlackBerry and a maglite), and they are in the red box: http://linksadventure.no-ip.org/pict...rcorehoses.jpg

It will flush with the cooling system. If you have oil in th e cooling system use the below procedure and replace bot the water pump and thermostat. If no oil then you can delete some of the painful steps.

FLUSH and REFILL
Drain the system and remove the thermostat. Put the housing back on the engine then you back flush through the top radiator hose into the block and out the bottom hose. Then you back flush through the radiator, in at the bottom and let it run out the top. Flush out the reservoir. Put the hoses back on and fill system with water. Add several ( 1 to 2 total) tablespoons of Lectra-Sol or Calgon automatic dishwasher soap. If its above freezing outside go for a drive and drive it till its warm and the fan definitely cycles on and off. You can just let it sit and idle also. Once it has been hot shut it off and let it cool down till its only warm. Now take the upper and lower hose lose again and flush through the block and radiator. You can pull the little hose off of the block and flush back through there and that will flush the heater core. Do a final fill and rinse with distilled water, you will need 7 quarts or a bit less for this. Now replace the thermostat and hoses. Add 1 full gallon of 100% antifreeze, yellow universal is best but use what ever you like, and top off with distilled water. Run with the reservoir cap off until the fan cycles and then put the cap on. There is a very small little check ball port in the thermostat housing, make sure that the ball rattles.

REWARD EXCELLENCE!
