Hi Everyone.

Any idea where this coolant could be leaking from? This is passenger side right under the radiator. New cap & coolant line to reservoir. Drips only occasionally. Radiator hoses all appear to be tight and no coolant is leaking from them.

 

Could be where the end tank is soldered on or one or more of the end tubes are soldered in. Cheap fix is Bar's Stop Leak. Or pull the radiator and have it repaired.

 

Cool, thanks! I'll give the Bar's Stop Leak a try. I am embarrassed to say it, but never heard of it. So I just pour it right into the Radiator?

 

Yes, it works well, be around since WWII. Also after you add it, add a little water in the can to get the rest of the pellets out, it is a semi solid.

 

Thank you. Getting some on my way home this evening. Hope it works... the radiator for this car is between $350-$600. Must be gold plated or something...

 

My 96 lumina I had to replace was over $100 at autozone.

 

So I added some Bars Stop leak last night. It did not immediately seem to stop the leak (I let it idle for 15 minutes like the instructions said). However I took it to a couple grocery stores later that evening and the leaking stopped. However I will point out that this leak seems to be intermittent (which drives me crazy). So I'm not sure if the stuff is starting to work or if this was just the same leak stop that I have been seeing. What I find is odd is that I would expect the exact opposite behavior. I'd expect more leaking when the engine is warmed up and I'm driving long distance, as opposed to when I first start the car and it is cold.

 

When you turn off the engine, the pressure in the radiator goes up since there's nothing cooling it. So it's not uncommon for a leak to only occur for a few minutes after shutting the engine off.

 

Thank you. That makes perfect sense. Guess I never thought about it. (Fortunately I've been blessed with cars that never had Cooling issues!)

 

Thank you for responding Guys. I ended up just replacing the radiator. only had to sell a Kidney to afford it.
