O.P., Most of us would agree with the above post. Can you explain what you mean by your C.A.C.(charge air cooler/ intercooler) "was toast"? It sprung a leak? If so, it may have occurred because the circulation pump for your intercooler was toast. Hot/Cold, Hot/Cold, expansion,contraction, etc. Did you R.&R. your C.A.C. before checking out the pump? Also, you mentioned that you changed the coil(singular?). We have (6) coils; but you knew that, right?
