When to Replace a Charge Air Cooler

Common signs of a failing charge air cooler include loss of power, black smoke, higher exhaust temperatures, boost leaks, and oil residue in the intake piping. Cracked end tanks, leaking cores and clogged fins all reduce cooling efficiency. If the unit is only partly damaged, compare your options first in our guide to repair versus replacement costs. If it is beyond repair, this cooler is a direct replacement for the models listed above.
