Leaking radiator drain plug on my Jeep Grand Cherokee 5.9?
I flushed and changed the fluid on the 98 Grand cherokee with the 5.9 liter engine that i bought 2 months ago.. Its one of the projects i have for changing all the oil/fluids in everything as the previous owner seems to never have done in along time.
I've never heard that its common to fail after replacing coolant.
Unscrew it all of the way until it won't come out anymore. Using a flat head screwdriver as an aid, gently pry it off will pulling on it with the other hand or a pair of pliers.
