RTV use on ignition coil connectors What to do, and what NOT to do.

2/7/2017 - Our Owner David Aragon encountered an ignition coil connector that had been sealed with RTV very generously. Needless to say it didn't come off!

While changing #2 coil on a 2001 Ford Expedition, we encountered an ignition coil that was sealed with RTV. While you may use RTV in certain circumstances, it is almost always unnecessary, and not a permanent fix. Most connectors have a gasket inside of them to seal out moisture, and water contact. In some cases where you may have a broken connector that won't stay on, you can apply a small amount of RTV to keep it held on. Make sure to use very little as RV dries and bonds very well, and can make a small connector difficult to remove. If you notice the gasket is worn out or missing, if it best to just replace the connector. They are usually very cheap to replace.
