e best way to deal with fouling is to prevent it from happening.

Fouling in oil cooler What is Fouling? In the context of an oil cooler, fouling is the accumulation of deposits on either the inner surfaces of the tubes (oil side) or the outer surfaces of the fins (air/water side). This layer of deposit has very poor thermal conductivity, creating a barrier between the hot oil and the cooling...

Troubleshooting Common Problems Problem Symptom Likely Cause Solution External Clogging High oil temp (air-cooled), reduced efficiency. Dirt, bugs, debris on fins. Clean exterior as described above. Internal Clogging High oil temp, low oil pressure, overheating. Sludge, carbon deposits, old broken-down oil. Flush internally or replace cooler....

Cleaning Procedures A. Cleaning an Air-Cooled Oil Cooler (Exterior Fins) Goal: Remove dirt, bugs, and debris to restore airflow. B. Cleaning a Water-Cooled Oil Cooler (Interior Passages) This is more complex and often requires professional cleaning. The goal is to dissolve sludge, varnish, and carbon deposits.

Maintenance of oil cooler  maintenance of an oil cooler, covering both air-cooled (common in engines) and water-cooled (common in industrial applications) types.
