hi,
i have recently been reading about anti freeze and wonder if i have done something bad. put a rebuilt motor in my 96 and thinking dex-cool was better, used it. i am now thinking that is not good.
since i am putting in a new radiator, can i flush the block well enough to rid it of dex-cool?
tia, peter
It's not a good idea in my opinion, no. Use the green stuff, change it every 2 years.
Yes...BUT...the thermostat will put a serious damper on your ability to flush out what is in the block. It might be easier to just pull the thermostat and put your hose bib right into the void left behind, and eyeball the lower hose until it starts to run clear. Then I would use some compressed air and try to blow out as much of the water out of the block as possible so that when you fill it with 50/50 coolant and distilled water you have as much of the mineral-laced city water out of the system as possible.
Best,
Chris
yes i started there and then saw some dex-cool dripping out of the iac/ heater hose so i will put the radiator in (no thermo) and run it for a bit to do a better job of cleaning.
thanks, peter
