You can try J-Weld, we repaired a 16" cracked 327 block with it, but all surfaces MUST BE cleaned and follow the directions with the epoxy! Good luck.
You can't fix a cracked head unless you can weld. it must be replaced with a new head.
It is not recommended to repair a cracked tank on a hot water heater with JB Weld. The high temperatures and pressure in the tank can cause the repair to fail, leading to leaks or even a rupture. It's safer to replace the tank or the entire hot water heater to avoid potential hazards.
No. Helicoil
Use special flux cored electrode without purging dam.
JB Weld? Drain fluid, make sure it's realllly dry. If it's cracked, smear JB weld or another epoxy compound that bonds to plastic, wait for it to cure (probably 4-6 hours), then refill fluid and see if it leaks at full operating temperature.
two of ways of doing this either get a new one or take it to some one who can weld aluminum very well unless of course your radiator is cracked you would come out cheaper to just buy a new one
You can try, but it will not stay. The heating and cooling of the manifold will cause the JB weld to fall off.You can try, but it will not stay. The heating and cooling of the manifold will cause the JB weld to fall off.
Replace the radiator. Try JB Weld or JB Kwik Weld on the crack first -- you can pick it up for $4 and it is definitely worth a shot. I have tried the jb weld it didn,t work . I had to buy a new raditor ANSWER I work in a shop where we routinely replace the plastic tank. If you have to repair the plastic tank then do it from the inside. You can separate the tank from the core by carefully loosening the aluminum tabs holding it in place.
If you mean cracked get a soldering iron and go over the crack very carefully to weld it back together.
Multi purpose fix allDevcon epoxy, or similar epoxies like J B Weld, will work for all steel,plastics etc. Able to withstand Ultra high temperatures and high pressure. Sandable. Available at Auto shops. I used it to repair leaking Landcruiser 4wd High ratio housing, and two sections of water cooling system.(and Laptop computer cracked hinge surrounds)
weld it with nylon rod using iron plastic welder.
