Q: Antifreeze puddle on time change cover on 1990 Ford Mustang LX

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have changed the water pump and theromstat on my mustang 302. Now I have antifreeze puddling up on the timing chain cover on the driver side. I re-sealed the theromstat housing and still have the puddling.I will wipe it up and with 2-3 hours is back.

Are you uncertain as to where the coolant is coming from? Is it traveling to the timing cover, or is it originating there? A 1990 5.0L could very well have a leak from the housing itself. Or it could be from a worn out hose not sealing entirely. Check clamps and even pull the hoses off, looking for pin-holes or cracks. When you disturb them, that's when they especially start leaking as they are aged.
