My radiator is cracked?

Question

My car radiator has been leaking out coolant for about a month now. I decided to call my mechanic and he said that copper radiators should not crack, they can bend but should not crack. He said it was probably a valve that is old. I don't see any leaks on the radiator itself. Any help?

Answer 1

he,s wrong on that! i saw them crack before. if you have a crack in it, sand it down good to the bare metal and put some jb weld on it, let it set up good and hard. it will hold. i have it on mine right now.

Answer 2

first you have to see the leak, the parts store will have a leak test kit, it has dye in it so you can see it.

the valve he spoke of is the drain valve and they can develop a leak.

i have seen and had to replace radiators that were cracked in the side, the last one i did was on a 2000 lumina,the side is plastic lol, other than that it was in great shape.

another way to find the leak is to place a large piece of cardboard under the car, if the leak is from under neath

i hope this will help  

Answer 3

You might have a hose leaking check that.

Answer 4

first you say radiator is leaking then you say you dont see leak.. which is it.... have another shop have a look at it all you have to say is you have a leak somewhere ... could be a hose could be a water pump could be a radiator. could be you need to find a better  mechanic ... cause if he was a real one he would have check it out and found the problem... and i dont know or have never heard of a valve other than the one that drain the radiator or the ones in side the motor which wouldnt have anything to do with radiator ... go some where else say i have a leak can you find it would be smarter

Answer 5

If you don't see any leaks on the radiator, why do you say that the radiator is leaking??????

Answer 6

Then its not the radatior that is leaking, could be a hose or water pump.
