was wondering ?how the best was to flush the cooling system on an 02 ctd,it is the original coolant, truck has 64k. Someone told me there was block drain plug,but i couldnt find it,an if you had to use distilled water instead of well water? thanks rick

 

You want to use distilled in your cooling system, most anti-freeze comes pre-diluted now, no mixing. Make sure you use what is recommended in your owners manual. As for the drain, I have not had to do that yet so I cant help. I used to pull the thermostat and unhook the upper hose on my old chevy.

 

does anyone know if there is a block drain plugor if i should just pull the bottom hose?

 

there should be a driain plug on the bottom of the radiator...drain it there 1st then yank the lower hose. not sure if there is a block drain plug or not, check the manual.
