Air cooled oil cooler Vs Water cooled oil cooler Comparison Table
| Feature | Air Cooled | Water Cooled |
| Cooling Medium | Ambient Air | Engine Coolant |
| Temperature Control | Varies with ambient air | Very consistent |
| Size | Larger for same capacity | More compact |
| Risk of Fluid Mixing | None | Yes (catastrophic if leaks) |
| Complexity | Simple, independent | Integrated with engine cooling |
| Best Suited For | Stable ambient temps, auxiliary systems | Varying ambient temps, main engine oil cooling |
