I have a leak in my radiator and don't want to use the stop leak stuff cause i hear it can F up your heater core. Any one have any ideas on how to fix the leak? It is leaking from the side where the end seals to the metal fins.

 

go buy a new one for 100 bucks or so... they really arent that expensive at like advanced auto or auto zone.........

 

1.) Drain the rad
2.) Let it dry out (or use a heat gun/hair dryer to dry it)
3.) Clean all the corrosion lightly with something like a small brass wire brush on a drill/dremel
4.) Clean it with alcohol
5.) Apply JB Weld
6.) Let it cure for a full 24 hours
7.) Fill the rad & you're done.

I once fixed the low pressure side of an R134a mini-freezer with JB Weld. The stuff is still going strong after 2 years.

 

thanks any other ideas?

 

Most radiator repair shops could probably take care of that. Not sure how much.

I've seen the JB weld method used with varying success. We did the repair on a customers car, no compaints to date. Likewise, we've done it and within 20 days it was back to leaking. It's a real quick, easy fix, yes (by all means, try it).

 

Best way would be to be a new radiator altogether, although this might not necessarily be the cheapest or easiest route.

 

Replace it or have it repaired. No more than what one cost its better to replace it.

 

I put a new one in for 120 and it works great.

 

Cool Deal. Glad you got it fixed.
