hi,

I bought 2 bottles of paraflu 2 weeks ago.
On the bottles there was a caption: "ultra protection" and the color of the antifreeze is red.
Somebody know if i can mix it with the ordinary blue paraflu that i have in my radiator?

DONT USE IT, it does NOT mix with the old paraflu and causes a waxy build up which clogs all the water ways. You need to buy the correct paraflu which is blue. Newer vehicles have the red paraflu fitted.

And if i already did it, can i leave it in the engine for a week and next week replace all the antifreeze? (i won't drive the car in this week...)
Can it clog the water ways within a week?

If your not driving it you may as well drain it

Its a chemical reaction so I guess it works fairly quickly, certainly Fiat have told all the dealers to never mix the two.
