## Questions & Answers

**Q: I have a small leak in the bottom of my radiator. When I opened the cap it was full with coolant and no room to pour in the product. What now?**
A: Drain some out using the drain-cock at the bottom of the radiator OR suck some out using a turkey baster.

**Q: does this work on ac compressor leak?**
A: Nope! You have to use a special sealer for A/C leaks that also has a dye in it to detect where the leak is in case the A/C Stop Leak does not solve the problem.

**Q: Will this work to prevent a leak from egr valve into the radiator coolant?  i have a egr leak in my audi q5 diesel.**
A: I buy this for dodge grand caravan . Didn't work

## Customer Reviews

### ⭐⭐⭐⭐⭐ Irontite cooling system stop leak
*by R***. on April 5, 2025*

This item came quickly. I flushed another type of sealer out of my heater core that had it clogged I used irontite flush worked great,but then the heater core leaked really bad, put in irontite sealer stopped the leak in 5 minutes and still have heat.... Great product!!!

### ⭐⭐⭐⭐⭐ Great sealer
*by D***N on February 12, 2024*

I am-one of the lucky people who happens to own a truck wiith one of those millions of pairs of cracked heads on vortec engines of certain years.At 100000 miles, I am in no mood to purchase and install new cylinder heads, l heard of this product on one of the automotive shows on Motor Trend tv. Product is high priced, but beats the alternative, as this stuff really worked-no more unexplained low coolant levels. If used , you must drive at higher speeds/rpms right after pour. So far, so good.

### ⭐⭐⭐⭐⭐ the cooling system puked fluid on the cool down. Needless to say
*by P***B on May 30, 2018*

I ordered this on a recommendation. 06 Jeep, 200+ miles, not replacing radiator for worn seals. I bought this stuff, introduced it into my system. First 24 hrs, the cooling system puked fluid on the cool down. Needless to say, not hopeful!. Drove it to work with lots of coolant to spare... 4 weeks, not one leak. I have had no issues on cooling system flow. I have used other products without the same results. I can say, the entire 3 step process is going to be applied to my other running vehicles, but, for a fix..... this one product was fantastic. I did seal a leak seal w/in a couple minutes.. the final seal took a couple days of driving. My leaks were the seals between the various plastic/metal parts on the radiator that Chrysler (Mercedes) elected to use. I really believe the engineers need to understand how to work on cars, and actually experience end user issues. (FYI, I was an engineer, build cars in my free time...
