Intercooler Fin Repair
Intercoolers improve efficiency and power in turbo applications by rapidly radiating heat from the compressed intake charge before it enters combustion. Intercooler fins play a crucial role in the intercooler’s ability to keep your vehicle’s intake temperatures cool. Over time, the intercooler’s fins can bend or clog from road debris and rocks, causing a disruption in airflow that causes a loss in performance, not to mention becoming a real eyesore.
Using a pair of flat-head screwdrivers and plenty of patience, methodically wedge the bent fin between both flat ends of the two screwdrivers and press together to straighten them back to their original shape.
If the screwdriver method isn’t working out, a pair of wide-tip tweezers with a flat face is another alternative.
Notice after using a set of tweezers that the intercooler fins were shaped in a square pattern. Don’t worry, we have a quick fix for that as well.
We used toothpicks to contour the fins by simply pressing alongside each edge to achieve a nice rounded corner, similar to the factory design.
Although the repair job proved to be tedious due to the fact that we went fin by fin, the end result was well worth our time spent as shown in the image below.
