My birthday is this week and i treated myself to new intercooler and coolant tanks from lethal. I just wanted to get some tips on the install, and what is all involved. From what i've researched, its just a unbolt the old bolt in the new. But what about the coolant in the tanks and in the lines? Should i change it all out, what should it be replaced with? And then how would i go about doing that. Any info is appreciated. Thanks for the help
