tl dr: Corrosion (once cleaned) is not a huge issue. It is just typical corrosion on the battery terminal. See this image: (NOTE: This is a 6V battery, but the same principles apply.) The blueish color you see is hydrated copper sulfate. When acid vapors escape from the battery, it can cause a reaction with any copper which may be in the terminal. The ...

Background Yes it's harmful. It is lead sulphate. It is toxic to ingest and breath. It is especially toxic to children, as you would imagine regular lead to be. It's not miscible in water but baking soda (sodium bicarbonate) neutralizes that acidic portion of the compound. The remnant compound of that reaction would be H2O and some CO. Action Use ...

Here's some quick art work to help you figure things out: The red circled area is where the negative terminal is at. Specifically the green arrow is pointing at it. You should be able to loosen the nut at the red arrow to gain access to the post to get the clamp off of it. As for what you can touch and what you cannot, this really isn't a problem, as ...

It's always good to oil the underneath regardless if there is salt on the roads or not. You will preserve the metal and increase the life of your vehicle. Once rust starts, it spreads like cancer. That being said, I would wash the underside and then get it undercoated. They should be washing the vehicle before they spray.

The part image in the link shows three wires: green, white and black. Combining the image with this blogpost, which explains how to hardwire the 240 taillights, the green/blue is a signal wire for the turn indicator, black is ground. White is purportedly not used: Options at your disposal Source the connector pair and solder/crimp them in place ...

This is anhydrous sulfuric acid that has leaked from around the terminal posts. It will rather quickly corrode the battery terminal connectors. Rinse it off with water first, to get most of it off, flush with lots of water. Then put a mixture of baking soda and water in the areas affected, then rinse that off. To keep it from returning treat the terminals ...
