All models: weak A/C cooling and noise — clogged condenser/radiators (how to clean)

On Teslas the front radiator stack quickly fills with fluff/dirt. The condenser sheds heat worse — the compressor runs at maximum and dies sooner. Solution: regular cleaning (with safe methods). Plus a critical refill note: Tesla A/C uses POE oil (viscosity ~80–90, ideally Denso ND-11) — PAG from roadside refill rigs kills the HV compressor.
