While it’s always best to remove the engine from the car to paint it, if that isn’t a reasonable option for you, follow these steps: 1. Prepare the Area: Cover the car parts around the engine with plastic sheet or cloth to protect them from the paint. 2. Clean the Engine: Using an engine cleaner or a degreaser, clean the engine block thoroughly. Get rid of all the oil, grease and dirt. After this, clean it again with soap and water if needed. 3. Abrade the Surface: Use sandpaper to slightly abrade the block. This will help the paint adhere to the surface better. Only expose the metal; be careful not to cause any significant damage. 4. Apply Primer: Once the engine is dry, apply a primer. Use a primer that is resistant to high temperatures, as the engine block gets hot when the car is running. Follow the instructions in regard to drying times. 5. Paint the Engine: After the primer is fully dry, apply high-temperature engine paint. You can use a brush or a spray can, but spr...

Q how to reset vw check engine light

To reset the check engine light (CEL) on a Volkswagen (VW), you typically have two main options: using an OBD-II scanner or disconnecting the battery. Firstly, with an OBD-II scanner, connect it to the OBD port usually found under the dashboard. Navigate through the scanner’s menu to clear the fault codes; this action should reset the CEL. If you don’t have access to a scanner, a more rudimentary method involves disconnecting the car’s battery. Disconnect the negative battery terminal and wait for about 15 minutes. This break in power supply will reset the car’s computer system, potentially clearing the CEL. However, note that disconnecting the battery might also reset other vehicle settings. It’s crucial to address the underlying issue that triggered the CEL before resetting it. Ignoring the problem can lead to more significant car troubles down the line. Ideally, diagnose the cause with an OBD-II scanner to ensure vehicle health and safety.

Q can tpms cause check engine light

Typically, the TPMS (Tire Pressure Monitoring System) and the vehicle’s check engine light (CEL) operate independently, as they monitor different systems. The CEL illuminates when there’s a malfunction or issue within the engine or emissions control system, whereas the TPMS alerts the driver to tire pressure discrepancies. However, in some instances, an issue detected by the TPMS, such as a faulty sensor or system malfunction, can indirectly lead to situations that might trigger the CEL. For example, extremely low tire pressure could potentially affect the vehicle’s fuel efficiency or emissions, indirectly causing the CEL to illuminate. Nonetheless, this scenario is relatively rare, and usually, a lit CEL involves issues unrelated to the TPMS. If both lights are on, it’s advisable to perform separate diagnostics to identify and resolve each issue accordingly.
