The next job on my list is to overtake AC. Now I have the suspicion that the system is leaking, since the residual pressure is zero. So I degraded the radiator grille and lighted off the AC cooler (Condenser). Conclusion: no oil stains, but dirt over dirt. All dry dirt, fluffs, dead animals (insects), sand and dust. Lamels are usually a good tip for cleaning now? High pressure cleaners are eliminated, so I can cut down all lamellas immediately. Brushes or similar eben. But how do you get this thing clean and well-drained again? After all, the main cooler together with ATF and engine oil cooler is also behind it…..
