Frequently Asked Questions
FAQs
Does my 4x4 need a GVM upgrade?
We are happy to do the math for you. There is a common misunderstanding with GVM and the true weight your vehicle can legally carry.
Do I need a secondary fuel filter?
A secondary fuel filter is the fail-safe for the diesel engine and for a planned trip away. Modern fuel systems are intricate, and contamination such as water can damage the injectors and then the engine. We recommend a fuel water separator for every modern diesel vehicle.
Does my A/C system need servicing?
Yes. If you spend a lot of time in the vehicle or the truck, the filter and the system should be sanitised and running clean.
Why is my A/C not cold enough?
Poor cooling can come from a refrigerant leak, restricted airflow, or a fault in the compressor or the electrical system. We test the air conditioning to find the cause before recommending a repair, so you are not paying for a re-gas that will not fix it.
Are you an approved inspection station?
Yes. AMET Diesel is an approved inspection station.
Do you service Hyundai trucks?
Yes. We are the local service and repair agent for Hyundai trucks.
Do you work on site?
Yes. Civil, earthmoving and elevated work can be done on site, backed by the workshop. Heavy vehicles also have a breakdown service.
Can you work around a fleet schedule?
Yes. Fleet servicing is booked around the operator's schedule, for government fleets and owner-operators.
