Need the right number, not a vague answer? This section covers the car specs drivers look up most often, including oil capacity, tire pressure, lug nut torque, battery size, wiper blade size, and other everyday reference data. The goal is simple: fast, clear, model-focused information you can actually use.
NFC at 13.56 MHz over a few centimetres, Bluetooth LE across 2.402 to 2.480 GHz, UWB on channels centred near 6.49 and 7.99 GHz with centimetre ranging: the published figures behind phone keys, which iPhones and Android phones support passive entry, and the fallbacks for a phone that is off.
Published EV charging numbers in one place: DOE charging levels (1.9 kW Level 1, 2.9 to 19.2 kW Level 2, up to 500 kW DC), the NEVI 150 kW and 250 to 920 V minimums, CCS, NACS, CHAdeMO and GB/T coupler ratings, and onboard-charger, pack-voltage and 10 to 80% figures from Hyundai, Kia, Porsche, Nissan and Lucid.
Published V2X figures with their sources: the 5.9 GHz band plan the FCC finalised in 2024, the 10 Hz, 300 m basic safety message, 3GPP latency targets for C-V2X, ETSI ITS-G5 channels and CAM rates, and what production cars in Europe and the US actually carry.
Published thresholds, sensors and test criteria for door opening warning systems: Hyundai Safe Exit Assist, Ford and BMW Exit Warning, the Euro NCAP 2026 dooring test and China GB/T 44173-2024.
There is no single place to look: the sensor sits in the thermostat housing on one engine, the cylinder head on another, and MINI moved it into the upper hose entirely. Documented locations and how to find yours.
Published resistance and voltage figures for engine coolant temperature sensors, with the part numbers, temperatures and OEM fault thresholds they belong to.
Bendix specifies 1200 to 2700 ohms and 0.25 V AC minimum for its passive sensor. An active sensor has no such number: it answers in milliamps, and an ohmmeter reading from one means nothing.
Where jack points sit and how they are marked, what federal rules require of the jack itself, how to confirm a lift before going underneath, and what to do when the sill has rusted through.
Published brake caliper torque figures from manufacturer recalls and service bulletins, why guide pin and bracket bolts differ by an order of magnitude, what piston size actually controls, and which caliper hardware is single-use.
Published VVT solenoid values from manufacturer service documents: coil and circuit resistance, supply and control signal, oil control valve test values, pinouts, torque figures and seal part numbers, each tied to the engine it applies to.
