Hello, I believe I need to replace my coolant flange. My car has been sitting for a couple weeks, and I noticed a large stain on the driveway from a coolant leak on the driver side. After inspecting the area, I believe I found the leak. My question is, could this be repaired/patched? Or does it need to be replaced? I’m not planning on keeping this Jetta for very long, so I’m looking for the most affordable fix. I did replace the temp sensor a couple years ago. Please check the pics! Any help would be greatly appreciated.
