So As i said in my other post.. i have the green coolant in my car,, prestone to be exact... i want to get it ALL out and add dexcool... how can i completly flush the system without worrying about keeping to much water in the block because it is very cold here in NJ and dont wanna crack my ls1 block...
help would be very appriecieted i wanna get the green stuff out ASAP

 

Unfortunately I don't have the answer to your question but I am wondering how it got green anitfreeze in it in the first place?

 

Ive Got Green too .... my intercooler resivoir is filled with it

 

Oh yeah forgot to ad that i know that jiffy lube will do it ..... they have a whole system .... it shouldnt be to expensive..... supply your own coolant they will replace it with that...

 

so ur saying i should bring it somewhere with a flushing system therefore they can get all the green prestone out of it and then it can be replaced with dexcool...
