The technician will start the vehicle and turn on the air conditioning system, measuring the actual temperature at the vents at the lowest and highest settings with a thermometer; at the same time, they will connect a manifold pressure gauge to check if the refrigerant pressure in the high and low pressure lines is within the normal range, determining if there is a chronic refrigerant leak.

The storage area at the roll-on/roll-off terminal is entirely outdoors, which is standard practice at ports worldwide. During the few days vehicles wait to be loaded, they will inevitably be exposed to sun and rain and accumulate dust. We will not provide custom car covers as this would significantly hinder the efficiency of dock workers moving vehicles.

We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).
