I have a very small leak in the top of my car radiator. Can this be used to seal that leak?

If it's plastic, it's probably ABS. Not much sticks to ABS. I'd bet the expansion and contraction from the heat and pressure would work it loose. The best thing for ABS is the plumbing cement made specifically for ABS pipe. If the radiator is metal, the Water Weld will work great. Just make sure it's clean and roughed up. Give it at least 12 hours to cure.

Maybe but if you can it would be better to take it to a radiator shop to have the leak fixed. Next best thing I would try is stop leak. Auto parts stores sell it especially for radiator leaks.JB water weld worked on my hot water tank for about 2 years until the hole rusted out more.

this is a great question. Yes, it can work as a temporary fix until the radiator forms another leak else where. Cool the engine completely then clean the area with rubbing alcohol, then apply. Worked for me with a 5 inch hairline crack. But replace your radiator!

I'd try it. I have since used it to fabricate a missing dishwasher rack wheel. It has held up to the weight and the heat so far. Clean the area well...mix the product well...and let sit to cure for 12 hours...not sure if it will hold under that kind of pressure .

I think to a certain degree you can use it for that purpose. If its a very important pipe i would avoid using it. However, if you use enough tape and make it tight, I imagine you can indeed fix a leak. I am sure it depends on the amount of water pressure and environment where the leak is.

I would only use this once (Twice if it doesn't completely seal the leak, which what happened to my last car). Don't quote me on this, but you need to resurface the head if it is warped and you are planning on re-using it. Now is the problem a warped head, worn gasket or a crack head? That is what you need to find out first. Bar's leaks should be a temporary fix until the problem is resolved.

Mine has not leaked. It is pretty tough. Even after backing my car onto the corner, it just popped back out by itself after a while. If yours leaks, you could fill it with sand or cement.

Might work if you clean the entire area first with min spirits or lacquer thinner. Surface needs to be clean and dry, oil free for this stuff to adhere. It's like spraying a thin film of rubber over the leak. Might be easier to just replace the gasket.

I bet this would work. Personally I would glue or epoxy the leaky spot first though.

I would think so...I repaired a leak in my Jacuzzi with it, and used masking tape as a form. When poured into the form, came out rock hard. Just make sure what u are adhering to is very clean. Good luck

Don't have the experience to support a definite answer for that situation. I added a smear to my exhaust gaskets to help seal better but a head gasket may blow this stuff out! I would try buying gasket material that is equivalent to the old one and make it yourself by tracing and cutting. This stuff should not be used to seal head gaskets! Just my opinion from my experience & mechanical knowledge. Won't work, don't do it!

It is not designed for that, but for keeping the rubber that seals around the doors, trunks, and hoods from drying out by lubricating the seals. However, if you want to waterproof your ignition system then you should try a 3m sealant. I check on this with calling 3m on their products and the person in the automotive section said that only a sealant would work for what you want. If you have further inquiry's on this you can call them at (1-888-364-3577) ask to speak to the automotive product section.

I have used this on external rubber seals on cars, and it works well as a moisture barrier. I assume it will work just as well for home window seals.

I'm not sure if it would or not. If it is a minor leak I believe it would. I don't know if any product that would repair a major leak, I would try it if It's minor. Can't see anything you would have to lose but 10-12 dollars. Could save you big bucks. Hope this helps.

Might as well do a whole bottle directly into the radiator. I did 3/4 of a bottle in my Honda Del Sol and it didn't help at all.

I sealed an 8 foot seam on my 5th wheel camper that leaked like a sieve. That wad more than a year ago and it still does not leak. Clean the old roof per the instructions and seal it with EternaBond.

If the leak is due to a bad gasket, this should work if carefully applied. I have used it on plastic and rubber with no problems. If the leak is due to a crack in the manifold, I can't be sure. But it's worth a shot since a tube of this stuff is cheaper and easier than buying and installing a new manifold.

doubtful. this stuff only works for a short time, then the leak will re-develop.Especially, if leak is at an increased pressure point.

If you are looking to seal the gasket then this product will help you do that. If you are looking to "glue" the two pieces together with this product, then this product will not help you. This product is a sealant not a type of glue.

It might depend on how bvad your leak is I dont know.But my car would overheat in one minute flat from a cold start. Bubbles and water coming up in the radiator.Honestly I think half the bottle did it but I poured inb the rest anyway.Some people put in an extra bottle in case i tries to start leaking again. I imagine half the bottle wouldnt hurt and if its going to work you should be able to tell,and probably wont hurt touse the whole bottle.Whats probably most important is to pour it as slowly as you can take two minutes or three even very gradually.
