Gonna be doing a coolant exchange I hope by late today. I have 2 bottles of prestone green stuff (straight coolant not 50/50) and I needed a third to do this. So I went to local stores and could only find Peak coolant. Says you can mix with any type of color coolant. Is it a safe bet to be able to mix these? I have read different post in other forums that says NOT to do this and only use motocraft. Didnt want to spend more money since I already have the prestone. A little insight would be great before I puck things up.

 

Sorry prestone might not be green stuff. I cant tell green from yellow sometimes. I do know the prestone is a yellow bottle and the peak is blue bottle both extended life. I also have 3gal of distilled water.

 

I prefer not to mix colors. I put a new rad in last winter and used the Ford Gold Longlife Antifreeze because that is what was in it before. Why take a risk that could leave you on the side of the road overheating?

 

I went and got a straw to poke around at the bottom of the tank. I got some mud looking substance out of the bottom? Cant be good!!

 

Im about half afraid to do a flush now. Hope leaks dont happen after this after I loosen all that chit up.

 

As long as the bottle says its compatible with any color you wont have any problem. I've done it many times and I cant say I've had any problem. Don't like Dex cool thats thee only amtifreeze I absolutely avoid..

 

Yeah I do know to avoid dexcool. My buddy runs that in his d-max and he is scared to death someday it will burn his head gaskets up. Told him not run it but hey, hes a Chevy guy he dont know how to listen lol. I tried to do the flush but it just didnt seem to drain like I thought it was suppose to so I am going to take to the shop and let them do it. When I pulled that mud looking crap out of my overflow tank got me really motivated to get this done right.

 

Cat Long Life is the best........it is red.

 

what I do is use a powerful shop vac Disconnect a lower hose drain and vacuum..

 

Never would have thought to use a shopvac. Did it work well?
