## Overview

## Description

POUR & GO, K-Seal’s advanced formula uses ceramic microfibres together with copper powder of varying size to ensure a fast and permanent seal holes up to 0.025in and cracks up to 0.01in wide by 0.5in long.The special chemical formulation can flow into cracks so fine that they cannot even be seen with the naked eye to form a super- strength seal. The crack or hole is actually filled from top to bottom with the K-Seal formula resulting in a complete ‘weld’ and permanent repair. The copper in the K-Seal formulation not only contributes to the strength of the repair but it also helps to conduct heat across the crack or hole. This eliminates hot spots that would normally form with a non-metallic repair.K-Seal can be left in the cooling system and will continue to repair leaks as they happen. You won’t even notice that there was a problem.

Review: Good product, worked like a charm - I had observed oil leak signs in the coolant, Probably faulty oil cooler gasket or Engine head gasket. I poured this liquid to the radiator and drove my Thar crde for almost 30minutes. Next day had gone for 400kms drive as well. No further oil leakage. Coolant looks clean now. Its been almost 3 weeks now. Oil mixing with coolant has stopped perfectly.
Review: Amazing product - There was a minor leak in my cars radiator Where as i have to top up the coolant in every 3 days. It confirmed that it’s a time consuming process and expensive as well. Then I saw about Kseal leak repair I used it and I am totally satisfied with the result Also I am posting this review after a month Totally issue resolved Thanks for such a great product

## Questions & Answers

**Q: will this work for leakey gaskets?**
A: It is designed to work on leaky gaskets.  If you have a small leak this product might be an easy and cheap fix.  It did not work for me.  Perhaps my leak was too large.  It is hard to tell.

**Q: Does it discolor the antifreeze? Thanks**
A: Unfortunately I can't say.  I have a GM vehicle that uses the orangish color engine coolant and it and this product are so close in color it's hard to say if it would discolor the usual green-colored coolant found in non-GM vehicles.  The other challenge is that I can only look at the coolant through an overflow reservoir and it's so dark when I look inside (I have to use an LED flashlight to see it adequately) that it would be hard to tell if there was any discoloration.

**Q: Can you use this in a 2013 escape?**
A: You can use it anywhere.  It's kept my 1998 Chevy Lumina going over 2 years with almost 178,000 miles on it!

**Q: can you mix this with barstop if you all ready put that in the radiator?**
A: I did mix this with Irontite All Weather Seal. Did the K-seal first. Irontite a week later. Just to be sure. Since they both said it can remain in the system. Two weeks, still good.
