## Questions & Answers

**Q: Will this work with a bypassed heater core? Or is the heater needed**
A: If you’re trying to stop a leak in Radiator it’s fine to have a bypass and not heater core.

**Q: I have o ring leaking when cold and stops leaking when warm. Will this help?**
A: It may, but it's main purpose is to stop leaks coming from small punctures or cracks. I'd recommend looking for products that work specifically on the seals, rubber O-rings or gaskets, such as NO LEAK. Hope this helps!

**Q: Say in i have a hole in my pump under here i pure the anitfreeze at an it leak out a little can i use this to seal the hole or what can i use to seal**
A: "Hole in pump"   Don't think this will work on anything bigger than pinhole.

**Q: in which country was this manufactured?**
A: This product was manufactured in the United States of America. Thank you for the question!

## Customer Reviews

### ⭐⭐⭐⭐⭐ I've always used alumaseal powder
*by W***O on September 23, 2023*

I've used the powder version for yearsand it always did the trick. Since I can't add straight to the radiator anymore, I thought I'd try the liquid. So far so good. I think it's fixed the leak, now I need to know if it's a permanent fix like the powder always was.

### ⭐⭐⭐⭐⭐ This Stuff WORKS !!
*by S***E on January 31, 2023*

I had a pretty large "pin hole" in my radiator. ( Just over a year old new replacement on T&C) in a cold engine. Topped Rad off with anti/water. Went on my way driving to town & back. Put about 100 miles on in 3 days. Was going to top off rad,,,,,but it was full. This stuff works. N ever had luck with Bars Leak in the past.

### ⭐ Like most radiator seals of today
*by F***Z on November 5, 2024*

If you use it, it may get you home, but you will have to leave the radiator cap loose. It cannot hold up behind any pressure. It is not good at all for head gasket.
