Was just check out my truck this morning and notice wet spot under the truck, investigated and found anti freeze / coolant slow drip looks like it coming from the head gasket on the back drivers side. This motor was replaces 2 yrs ago with an amg unit. Any suggestions ? It Hasn't leaked anything before. Should I pull the head and replace, or throw some stop leak in. I topped up the coolant for now and going to watch carfuly. I just finished installing the lift pump relay from Kennedy yesterday, working fine. Was hopeing for a few Kl of worry free driving , Damn it all.
