We agree the checks before booking. The truck, condition, location, access and seller permission guide the work. We consider visible condition, test results and service records. We record any checks that could not be completed.
Engine, diesel and diagnostic checks
Checks may cover starting, idle, leaks, smoke, noise and warning lights. A cold start is useful where available. We may also check fuel, intake, turbo and boost systems and scan data. Deeper fuel, compression or internal engine tests need a separate agreement.
Heavy diesel diagnosis and repairs
Cooling system and overheating signs
We can check coolant level, visible leaks, hoses, the radiator and fan operation. We also look for signs of previous overheating. Internal blockages or faults that only appear under load may need extra tests. Tell us about any cooling problem the seller has reported.
Gearbox, clutch and driveline
We can assess gear engagement, noise, vibration and leaks. Accessible tailshafts, universal joints, bearings, mounts, axles and differentials may also be checked. A suitable road test can show some faults. It cannot reproduce every load, temperature or work cycle.
Brakes, steering, suspension and tyres
We can check visible brakes, air systems, steering, suspension, wheel ends and tyre wear. Heat, leaks or uneven wear may need deeper checks. Good tyre tread does not prove that bearings, kingpins or suspension are sound. Wear patterns help guide the tests.
Further truck brake inspection and repairs
Electrical systems and cabin operation
Our qualified auto electrician can check starting, charging, batteries, lights and accessible wiring. Cabin controls and air conditioning may be included in the agreed scope. A flat battery or poor access can limit tests. Faults that come and go may need more time.
Chassis, cab and visible structure
We inspect accessible chassis, cab and mounting points for cracks, damage, rust and changes. We record visible concerns and previous repairs. Hidden areas are not all exposed. Structural concerns may need a specialist. This is not an engineering report or structural certification.
