flushing the cooling system. Any advise?
2000 K2500 7.4L
Just replaced the intake gaskets, now I want to flush the cooling system and get rid of any left over Dexicool. How much coolant do I need? What flush do you recomend? Do I need to put in any additives with the green coolant? Thanks.

I have used dexcool since 1996 and my 1996 and 2000 vehicles have no coolant issues. I do use distilled water and 65 % dexcool to 35 % distilled water . replace every 3-4 yrs.

after draining the radiator...
remove the thermostat and upper hose from the radiator. point the hose from the thermostat, down.
stick the hose in the radiator cap opening
run the truck with the heater on full blast for around 5 min, untill water comming out of the engine is clean.
also a good idea to CLR or scrub out the overflow bottle some how...
then your basically done. just refill. i usually do at least 60/40 antifreeze/disstilled waterGas was $1.83 when Obama took office.....
