i just got my teg the other day and there's a leak on the top of the radiator. its tiny, but it's still spewing coolant all over the engine bay. it looks like someone already tried patching it with some clear/white looking stuff. should i take that off and put some JB weld on there, or is there some other stuff that would probably work better?

 

i heard alot about jb weld, but i dont think it holds very well

i have repaired radiators with fiberglass.

 

jb weld doesn't bond to areas that are 1. painted, 2. wet, 3. non metallic. the top of the tank is plastic, so it probably wouldn't hold, use fiberglass

 

yeah, i searched after i made the post i think im gonna try some epoxy untill i can get a new radiator.

 

i dont think epoxy would hold that well either after it gets so hott.

use fiberglass its so cheap and easy to do.

and it WILL hold , mine did.

 

you can get a plastic weld at auto zone. It is right next to the jb weld. It works well as long as you clean the area around the leak.

 

well i put some bar's stop leak in it this morning and it didnt do anything. now its overheating and my A/C wont work. so i got some plastic weld, i'll see how that works out tonight. it says its good up to 200 degrees, so it should work fine till i can get a new radiator.

 

it worked on mine foe 5 months

 

I did it to my friend's 240 and it works for now.

Bar's or plastic weld?

 

Say NO to JB weld on radiators. The moisture from the radiator wont help it stick. Not to mention, the heat will just form another crack. DId it to my accord when I was 16....Cost me a whole new engine.

JB weld

 

I used jb quick weld on a indented hole on my rex's rad and it hasn't leaked for a week. but im still getting a new radiator. should be here tomorrow.

 

I was just watchin mythbusters the other day and they proved putting an egg into your rad seals up holes haha....just bored and thought i would share

yes, a new radiator.

 

Use a soldering iron and melt the radiator back together first then sand and epoxy it for strength. I used fiberglass cloth dipped in epoxy worked fine for a couple years. If you used the bars stuff flush it promptly it will plug up your heater core and its a bitch to replace that.

 

i've used a little on the plastic tank of a rad once. it held for a while but eventually i replaced it.
