At ALLIED Engine, we provide a wide range of engine repair services for petrol and diesel vehicles. Our certified mechanics use top-grade tools and parts to make sure every repair lasts.
If your engine is making ticking noises or feels jerky while driving, the problem could be a damaged cambelt or timing chain. We replace faulty components to prevent further engine damage. Head gasket problems can lead to overheating and coolant leaks. Our experts quickly diagnose and replace blown gaskets to restore engine performance.
Electrical faults like flickering lights or trouble starting the engine may signal alternator or plug issues. We test and repair/replacement alternators, spark plugs (petrol), and glow plugs (diesel) to keep your engine firing up on the first try.
Loss of power, strange noises, or white smoke from the exhaust are signs your turbocharger might be failing. Our turbo repair and ECU testing services bring back engine efficiency. We also fix leaking water pumps to prevent overheating.
In severe cases where the engine is beyond repair, ALLIED Engine provides full engine replacement or rebuild services. We’ll inspect your engine and suggest the most cost-effective solution.
