Types of Engines, We Offer

Moon Auto Parts sells almost all makes, models, and types of used and remanufactured engines. Some of the significant engines that we deliver are internal combustion engines (spark-ignition (petrol) and compression-ignition (diesel)), stroke types (within IC engines), diesel engines, petrol engines, electric motors (AC motors (most EVs) and DC motors (smaller EVs/robotics)), hybrid engines (combining combustion engines with electric motors), and alternative & niche engines (including rotary (Wankel), hydrogen fuel cell, biofuel/flex-fuel, and external combustion (steam)).

Engine Codes

DTCs, also referred to as engine fault codes, are used to identify and diagnose malfunctions in a vehicle. With OBD-II systems (light- and medium-duty vehicles from 1996 onward), the Society of Automotive Engineers (SAE) International created a standard DTC list for all manufacturers. The “check engine” light is an alert that a DTC is present, and it requires a diagnostic tool to read and interpret the engine fault code. DTC codes can fall into two categories: critical and non-critical codes. A DTC comes in a string of five characters. J1939 DTCs are based on four fields relaying data in a DTC fault. Permanent Diagnostic Trouble codes cannot be reset by using a diagnostic scanning tool or disconnecting the vehicle’s battery. Reading DTCs requires a scanner. Active codes refer to current malfunctions that have tripped your check engine light.

VIN Matched Engines & Fitment Support

Engine compatibility includes more than just physical dimensions; it also includes electronics, codes, and fitment. As the main checkpoint, take into account the engine codes, which include displacement, fuel type, year, and variant. There are many options for you to choose from. Remanufactured engines, reconditioned engines, low-mileage used engines for sale, and hybrid conversions are examples of sustainable options. If you want expert guidance, we, Moon Auto Parts, will help you drive through this confusing process with utmost precision and expertise from purchase to installation for free.

Engine Quality & Inspection Process

Understanding that a thorough vehicle inspection is essential to assess accidents, near-total losses, or pre-lease conditions, our experienced engineers begin the inspection process by verifying vehicle and owner details such as make, model, year, and VIN. Preliminary steps include visual inspection for spot issues like oil leaks, rust, damaged belts/hoses, and milky residue that indicates a blown head gasket. By listening to the engine, we usually detect problems with knocks, squeals, or rough idling. We also check the color of the smoke to determine if oil is being burned, if there's excess fuel, or if it's a coolant leak. We also examine the PUC certificate to gather information on emissions and the state of the engine. Our engineers also perform scanning for diagnostic trouble codes using an OBD-II scanner that shows hidden sensor or system faults and a compression test to evaluate performance. The testing is concluded with a final QA approval.
