So i discovered a small hole (about the size of a pea) in my radiator and i dont know how to fix it. i bought Bar's leaks radiator because it says it stops leaks but it says dump it in the radiator with coolant and let it run for 15 - 30 minutes the only problem is that my radiator leaks a lot really fast and i dont know if this will stop the leak i was wonder any opinions

 

A pea sized hole would need to be soldered up.

Stop leak likely won't fix.

Any rad shop could do it, but unless it is from a .22 rifle, I believe you need a re-core job since it may only be the tip of the iceberg, as it were.

 

Got any jb weld? Lol

 

Any idea how much a shop would charge about to do that?
I was going to ask the same question but mine is a 1/4" crack on the top that spits fluid out in small amounts. Im a ebay freak and saw 3 core radiators for $209 and if there is a cheaper easier way of keeping mine till I get money it would be nice. Also don't they do a thing called radiator brazing for holes that big?

 

Go to the junk yard and get a 4 core radiator and take it to have cleaned. I have a 4 core with a 165 thermostat and a 7 blade fan on a clutch and I've never seen it go passed 165 degrees, its also a built 390.

 

what trucks in the yard would i look for that have them?

 

ive got 4 cor from a 70s not sure on year stationwagon 400 ci i think works great brother gave it to me had to get an extention an a shroud.
