Coolant looks a little gross. How do I go about flushing the radiator??
thefabzx3 said:just pull off the lower radiator hose, as long as you are careful it own't make too big of a mess and it is heck of a lot quicker, and you will get a lot of coolant out of the block that way. also pull the heater hoses from the firewall and that will get even more out.
Someone on another board mentioned a good point. If were to just let the water from a garden hose flow, wouldn't the cool temps of the water close the thermostat? At that point you'd have to let the T-Stat open again and circulate and then drain once again.i did mine today just unscrew the overflow cap on the tank then open the drain plug and let it flow for a while. Then you may want to run the hose into the overflow tank for a bit until its running perfectly clear out of the drain plug.
Tighten the drain plug fill it then start the car and let it run then top it off if need be.
That's exactly how I did it.noresull said:Drain coolant, remove Thermostat housing and thermostat, stick garden hose in engine side of thermo housing and turn on, watch water running out, keep doing this until water is clear, place hose in upper rad. hose, keep flushing until water runs clear. Replace hoses and thermostat. It's your choice if you want to replace it, I usually do because I'm there. Fill the cooling system. I will buy 2 gallons of coolant, dump one gallon of un-mixed coolant into reservoir, there is already aprox 1 gallon of plain, clean water in there from flushing, then take the 2nd gallon and mix 50/50 and use that to top off as neccesary.
