My experience would say no. It may last at first but road condition and depending what part of the radiator tank you put it on, you may be real upset on your trip to the mall or Saturday night out with friends and good old Mr. JB desides to retire
I had 2" crack on top of the radiator. I tried JB Weld and other similar putty but they did not work on plastic. I bought Permatex PermaPoxy™ 5 Minute Plastic Weld from Advanced Auto Parts for $7. It took 10 minutes to finish the job and it worked.
weld it with nylon rod using iron plastic welder.
By replacing the radiator. I've seen people use JB Plastic Weld and it only holds up for a few weeks.
Jb weld expoxy mix
I doubt very much it will hold.
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 the seam is coming apart, use J B Weld between the parts and then if possible screw in 2 small self tapping screws through both parts at each end. This should pull the parts together, then finish off the top of the seam with J B Weld also.
sand the spot to be fixed and used some j b weld apoxy it's sold in walmart in the automotive area.let sit for 2 hours and you are good to go.Improvement done by sickofjunkJB weld is a great idea for a lot of things however getting it to bond to plastic will most likely never happen. That was the first thing i tried on my radiator too but i had no luck with it. To fix plastic on a radiator replace it that is the best way.Or buy a new one that always works out great
you melt it
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.
Yes, It's very tricky and takes time to do it. Process called Thermo Welding. There is many DIY guide on the Internet. basic 101 about thermo welding...You have two options.1st option is to buy professional plastic welder kit (starts $50-$300) that will melt plastic parts and fuse it back as one new solid part.how does it work!Simple you heat whole area where plastic welding will place, then once you reached required temperature for the plastic that you weld, use your plastic welding gun and the plastic ROD (ROD is new material that will be added to the welding process)BTW very important you can only weld SAME type of plastic together, mixing it with other types of plastic may cause bad results.Once you have both radiator and new ROD heated they will slowly join them self.This is not easy but works,2nd option: instead buying plastic welder you can try to use adjustable temperature or none adjustable soldering iron. On none adjustable soldering iron you have to play with the distance of the tip so you always have same temperatures on the part's it's very important to reach correct temperature for this to get successful results.I hope this little info will help.Boki
