+61 424 222 888Real reviews from Melbourne truck operators and fleet managers about our diesel engine repairs & rebuilds service.
"Scania R series de-rated to limp mode in Thomastown due to an engine fault. Truck Mechanic arrived within the hour, connected diagnostic tools, traced a failing injector on cylinder four and had the replacement fitted the same day. Back on the road by 6pm. Exceptional diesel engine knowledge — highly recommended."
"We run 22 Hino trucks out of Campbellfield. Truck Mechanic handles all our servicing — zero missed services, fast callouts, transparent pricing. The best fleet service provider we have used in Melbourne."
"Called at 11pm on a Saturday and Truck Mechanic was on site within 90 minutes. Fixed the fault, got us compliant and back on the road. This company genuinely operates 24/7 — not just a marketing line."
