Welcome!
The answers you get depend on the information you give...
Also, what area of the metromess are you in? I'm in Lewisville but the larger majority seems to be in the Arlingtongue area.
Does the cooling problem rear its head constantly or is it only at high speed or while idling in traffic on hot days? With or without AC running?
Exhause, intercooler, and brakes should be straightforward. You'll want to buy a new cap for your brake fluid reservoir to do the TCB version of a speed bleeder. This way you can flush that nasty old fluid out when doing the brakes.
