Identify the controls and fitted equipment
Record the model year, original market, powertrain and climate-control functions on the candidate. Check which vents and controls actually exist, whether rear passengers have useful airflow and whether advertised seat features are fitted. A China-market Traveller and an export T2 should not inherit each other's equipment list. Use the version identification guide before assigning value to a feature. Read the applicable operating instructions so an unfamiliar mode, closed vent or disabled rear setting is not mistaken for a failed component during inspection.
Document the starting conditions
Record ambient temperature, sun exposure, how long the vehicle was parked, cabin occupancy and the chosen settings. Note whether windows were briefly opened to release trapped heat and whether recirculation was selected. A recently cooled showroom car is not comparable to one parked outdoors for hours. Use a suitable thermometer consistently and record elapsed time, but do not apply an invented universal pass temperature. Ask a workshop to interpret the measurements against appropriate service information. Avoid leaving people or animals in a hot parked vehicle while preparing equipment or waiting for a test.
Compare idle and normal road operation
Observe cooling while safely stationary and during a legal ordinary drive, using a separate passenger to record findings. Keep settings comparable and note fan noise, airflow changes, odour and any warning messages. If performance differs markedly between stationary and moving conditions, inspect airflow, fan operation and system control rather than immediately ordering a refrigerant refill. The cooling-system guide helps connect cabin complaints with wider temperature behaviour. Never continue a drive with overheating warnings merely to complete a comfort test, and never open a hot coolant system.
Evaluate the people in the rear seats
Set the front seats for the actual driver and passenger, then assess rear airflow without obstructing vents with bags or seat covers. Check whether cold air reaches the occupied positions and whether the chosen fan setting becomes uncomfortably noisy. A family using child seats may have different needs from two adults on a short test drive. Combine the result with the family and luggage assessment. Document comfort observations as observations, not laboratory certification, and distinguish lack of a desired outlet or control from failure of equipment that is actually fitted.
Investigate odour and intermittent faults
Musty smells, weak airflow and misting may involve filters, drainage, contamination or other faults. Refrigerant loss requires diagnosis of the leak rather than repeated topping up. Have a qualified air-conditioning technician use the correct equipment and refrigerant specification; do not vent refrigerant or bridge controls to force operation. Repeat a hot restart and check whether the original symptoms return after the system has been operating. Retain scan results and repair records where relevant. A seller's claim that every vehicle of the model behaves this way is not a substitute for a supported explanation.
Write a climate-specific acceptance decision
For a buyer in a hot region, a mild-weather test may leave an important limit unresolved. State what conditions were achieved and whether a destination specialist can assess the remaining concern. Price a diagnosed repair separately from optional improvements such as permitted tint or sunshades. Do not let accessories conceal defective cooling or create visibility and compliance issues. A new vehicle still needs a functional delivery test, while a used example also needs service and leakage history. Accept the candidate when its fitted equipment and verified performance meet the intended cabin task, not merely when one vent feels cold.
Apply the checks to a shortlist
A family buyer might compare one candidate tested indoors and another parked in direct sun. The first appearing colder immediately does not establish superior condition. Recreate reasonably comparable starting conditions or ask the inspector to state the difference. If the sun-exposed car still performs poorly after appropriate testing, investigate it; if both meet the required task, compare verified equipment and repair history instead of the initial sensation.

Questions and answers
Is one cold vent enough to pass a T2 air-conditioning check?
No. Check cabin coverage, airflow, operating conditions and repeatability, including rear-seat needs.
Should weak cooling be fixed by adding refrigerant?
Only after competent diagnosis. Incorrect charge, leaks, airflow and control faults require different remedies.
