(Oops... see elsewhere.) Replaced the A/C compressor... bought used online for $280. 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.

Compressor is noisy. After the radiator leak/replacement in December, we didn't recharge the AC... with the super cold weather it would be hard to get reliable gauge readings (our shop is quite cold). The evacuation for moisture and recharge with the gauges went well,.. Temp. dropped from 22°C to 8°C. But the compressor is a little noisy. Found it difficult to determine how much AC Compressor oil was in the system (wonder if the little cotton analyzers are accurate?). I suspect it needs more oil. I'll update the result.

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.

Weak cranking and it wasn't cold out. Sometimes OK, sometimes NOTHING. Replaced older battery. Charging voltage 13.69v. Checked ground wires. Checked for corroded or shorted out main starter cable from battery. HAD to be the starter. Reports on refurbished starters were awful... often lasting only 1-2 years. New starters were stupidly expensive for Infiniti. So... found a replacement used starter at the local auto wrecker for $150 on a car that had only 80K on it. (Hey... if my original one lasted until 257K then this used one likely have plenty of life left.). Gave myself a Xmas gift and got my mechanic to simply put in IN... no diagnosis etc. JUST labour time. 1hour. $138. I now LOVE the enthusiastic cranking each time I start up my Black Beauty!

Replaced both front strut assembly with ones off a low mileage vehicle. I'd tried buy the whole "assembly" new, but they didn't seem them that way. So I then attempted to just to change the shocks, but when compressing the springs to remove the top nut, the spring warped sideways. A better, and safer option was to get the used entire assembly.

Fuel Gauge Malfunction. Changed a computer module on top of the radio that controls LOTS of things like the AC/Heat system, airbags, locks, remote etc. The sensors in the gas tank were good. The "self-check" of the instrument panel passed. followed the wiring from gas tank to that white module with 3 (?) plugs with multiple wires on top of the radio. Relatively easy access... but was really hard and unbelievable to diagnose !
