Our Menu of Engine Work 

While there are too many specific mechanical tasks to list here, Tinjtoo Auto Repair can share a menu that outlines our engine repair services. The key to delaying engine repair as long as possible is preventive maintenance. Let us partner with you to protect your automobile with routine services. These include major mileage visits, factory-scheduled checklists, and more frequent touch points like fluid tops, oil changes, and tire monitoring. When your engine requires more, our team can handle it all. Nothing is too difficult. Some of the more frequently performed engine repairs are common to gas- and diesel-powered engines. For instance, either type will quickly sustain damage and even experience catastrophic failure if overheating persists. Therefore, it’s imperative that we immediately address concerns such as a clogged radiator, broken thermostat, or leaking coolant. Other repair issues may sound the same, but the underlying causes differ between gasoline- and diesel-powered engines. For example, neither will take you very far if it won’t start. A common cause of ignition failure in your gas model is worn spark plugs. The spark that ideally is produced ignites the gasoline for combustion in the chamber. Bad plugs can also lead to misfires, rough idling, and poor fuel economy. Because diesel fuel is less volatile, an engine using this power source relies on glow plugs to warm the fuel enough for combustion. When glow plugs are not working properly, you’ll likely experience the same ignition failure problem. Both kinds of engines can be damaged by degraded oil, too. In gas models, dirty oil typically comes from a failure to change the lubricant often enough, leading to decreased protective value and sludge formation. A diesel engine is more likely to be plagued by oil oxidation, particularly if the vehicle has been sitting unused for an extended period. Tinjtoo Auto Repair can make any engine repairs your automobile requires. Should your vehicle’s engine be damaged beyond repair, or if repair isn’t financially feasible, we can still help. We also make engine replacements.
