Can you use dex-cool in a 2006 scion xb - 2006 Scion xB

I woouldn't use dexcool in anything, It will ruin your intake gaskets and cause antifreeze to leak into the engine. If you don't have your owners manual to use as a guide, get on the Internet and simply type in "what is the best antifreeze for a2006 Scion". You should find the answer there.

Dex- cool is the orange coolant, you can use this only if it already has dex -cool, dont mix it with the green type coolant, if it has green coolant you will need to drain it before using dex-cool
