Coolant system issue
 

I think I'm having the same problem that this guy in the video had. When I come back to my car after a long ride I see coolant on the ground underneath of the overflow tank. Does anyone know what causes this?

A failed filler cap or failed coolant seal. The latter is usually accompanied by other symptoms.

I would invest in both new caps and see if it improves. If not, have the system pressure tested. Note the fourth listed symptom in the 3rd. post ---> https://www.rx7club.com/new-member-r...-idle-1051067/

Thanks for your help!
