I keep getting dripping under the radiator when I turn the engine off and let it sit. The thing has soaked about a 3 ft circle on the pavement. Is this normal? I'm thinking the newer coolant overflow bottles may prevent this. Will it leak a little each time? Thanks

Fluid would fill up my front crossmember and just sit there. While driving people would yell out the window hey you are leaking! My truck wasn't overheating so I was puzzled then I realized I had no overflow tank! So I bought one of those long skinny polished stainless overflow tubes for around $60. I had to cut/grind off the tube that exits the near the cap at the top of the radiator and I used some jb weld to hold in a new piece of metal tubing. Then I used vacuum hose to run down to the bottom of the new overflow tank. | | |

How's the condition of the radiator cap? It could be as simple as replacing that if it's old and doesn't seal correctly. You say you replaced the fluid, might be that opening the cap disturbed the seal if it was old rubber.
Or, in the case of a Jeep I recently worked on, it could be that the radiator is so plugged up that it's overheating and pushing the water out it top. We noticed the tank at the top of the radiator was literally bulging outward.

Mine is about 1-1/2 inches below the filler. If it pukes enough out that you can see the top of the coils, then you have a problem.
