Cooling system. A persistent small leak in the radiator somewhere near it's center right side. Replaced radiator with a premium one bought online. Usually a such a repair is easy... just take off a bit of shielding on the top, a few screws and lift out the rad. BUT with the EX35, we had to get at everything from the front... remove the entire front grill, cross bars, remove the A/C lines and evaporator TOO! (had the CFCs / Freon captured by my mechanic for $C45 (friendly to the environment!). Both the A/C compressor from last year and the radiator are working fine after many months. Have to recharge the A/C soon... summer is coming. Happy I have the evac pump, gauges and freon already.

The Check Engine Light started coming on randomly over the last year. Each time is was the same OBC error OBD code P2A00 - A/F Sensor 1 Bank 1. It would clear itself after a few days, but then not so I erased it. Now the light returned all the time. I will change now change the sensor and report back on the next cycle.
