### ⭐⭐⭐⭐⭐ Correct sealer to use on Ford 302 head bolts threads that protrude down into the water jacket.
*by R***K on 14 June 2026*

This is the correct sealer to use on Ford 302 head bolts threads that protrude down into the water jacket. No leaks, worked perfectly.

### ⭐⭐⭐⭐⭐ Excellent
*by L***Y on 1 August 2026*

This stuff is great! No more Teflon tape for me

### ⭐⭐⭐⭐⭐ Best thread sealer for automotive application
*by T***E on 19 December 2020*

This is the best thread sealer for automotive application. I was replacing the coolant temperature sensor for the 2004 GMC Envoy 4.2l I6 Atlas engine (one of the smoothest idling GM engines). I ordered the factory part from GM and changed it out. The next day I noticed a coolant leak. The factory part comes with white thread sealer, dry, on the threads all ready for installation. However, the sealer was not working as it should. I removed the part and did a visual inspection. I did not see any issues with the threads. I did chase the threads to make sure there were no burrs. Then, I put this thread sealer on the threads making sure I only covered the same area as the factory thread sealer. You don't want to cover all the threads as you will lose a the electrical ground connection. After installation, watched for leaks every day for a week. Problem solved!
