I walked outside today and found about what looked like about a quart of coolant on the ground. got up and under ther and it looked like it was coming from the bottom of the radiator on the dirver side were the plastic tank conects to the metal core. i filled my coolant tank back up and havnt leaked scince then. any ideas?

 

Like a bad dog won't come back an bite you. Probablly the tank to tubes connections / gasket is weak. High pressure after shut down forced unsealing. Next time pressure goes high the leak will return. With age you might look for rad assy and be done with. Some good aftermarket pieces are avalaible and save a ton of money. Look on internet.

 

Mine did the same thing, but over time it got worse to the point of replacement. Leaks rarely fix themselves.
Apparently there is a radiator site that sells a repair kit for the side saddle tank seam to the main body. I have read of others on this site who have used it with success. Might be worth checking out.

 

it did the same exact thing again to me today.leaked in the morning now it isnt. im gonna try to make the 150 mile trip to phoenix where i have acces to tools and such. i put some stop leak in it. hopfully it will hold. also will pick up a new radiator while im down there in phoenix. chepest i have found is $259 at napa. does anyone have a cheaper idea besides the internet bc it wont get there in time?

 

I would remove the cap, no pressure to blow the leak should it become weak. Mostly downhill anyway, some good climbs though. Good luck

I have not bought from them yet, but I was leaning hard to National Cooling products, 1-800-375-7777. They have a distribution center located in Calif, but pretty close to Flagstaff.
