An OBD2 scanner is a device that connects to a vehicle’s onboard diagnostics system to read trouble codes, view sensor data, and help identify problems reported by the engine and other modules. It does not repair the vehicle or automatically prove which part has failed. This article explains what the scanner measures, what its codes…
Yes, 2-ton jack stands are often enough for many cars and light vehicles, but only when their rating, working height, placement, and condition are appropriate for the vehicle. A pair rated at 2 tons each has a combined nominal capacity of 4 tons, although the label must be checked because some products describe capacity differently….
You can lift a car with a hydraulic floor jack by positioning it on a solid, level surface, finding the vehicle’s approved lift point, and raising it slowly until the tires clear the ground. A jack alone is not a safe support for working underneath a vehicle, so place properly rated jack stands before getting…
Yes, Harbor Freight floor jacks can be good for home mechanics, tire changes, brake work, and other occasional repairs, especially the better Daytona models. They are not automatically equal to professional shop jacks, and the cheapest option may trade durability, lifting speed, or refinement for a lower price. The counterintuitive detail is that price alone…
No, you cannot safely use any jack on any car. A jack must have enough weight capacity, lifting height, and a saddle or contact point that matches the vehicle’s approved lift points. The right choice depends on the car’s weight, ground clearance, construction, and the repair being performed. A compact scissor jack may work for…
ECT on an OBD2 scanner means Engine Coolant Temperature. It is the temperature reading reported by the coolant temperature sensor to the vehicle’s computer, usually shown in degrees Fahrenheit or Celsius. If you are checking a car with a scanner, the goal is usually to decide whether the engine is warming normally, running too hot,…
Yes, jack stands can be safely placed on pinch welds when the vehicle manufacturer identifies the weld as a support point and the stand contacts it correctly. The seam must be strong, straight, and protected from a stand saddle that could crush or bend the metal. The real danger is not the pinch weld itself…
A leaking hydraulic jack can sometimes be repaired by replacing a worn seal, O-ring, or release-valve seal and refilling the reservoir with the correct hydraulic jack oil. If the cylinder, pump body, piston, or pressure components are cracked, deeply scored, badly corroded, or inaccessible, replacement is usually safer and more economical than rebuilding it. The…
Yes, Duralast floor jacks can be good for routine home and light-duty automotive work, but their value depends heavily on the specific model, capacity, condition, and how it is used. They are generally practical, accessible options rather than automatic substitutes for a professional-grade shop jack. The small detail that often changes the decision is not…
Yes, you can safely support a car on four jack stands, provided the stands are correctly rated, positioned on approved support points, and placed on a hard, level surface. A floor jack should raise the vehicle, but the jack stands—not the jack—must carry its weight while you work. A rushed setup can overlook more than…
