Irontite All Weather Seal, Blue, 16 oz

This stuff really works.I am very skeptical about additives in general,so when I heard about this product I really didn't expect the results I got.I was hoping this was going to prove me wrong and it did.I had a small antifreeze leak that I couldn't even find the source on my 2002 for taurus.I had changed the water pump about 6 months prior and this small leak kept showing up on the floor of the garage.I power washed the motor and still with mirrors etc. I could not find the source.I was told about this product and it worked.No more leaks and I didn't have to pull the water pump again.Ps. All hoses and clamps were find so it may have been sweating out from one of the bolts that secure the pump,but this did it.

It worked perfectly and no problems to put it in radiator.

Seems to have worked well sealing a head gasket leak. It's only been a couple weeks, but seems to be holding.

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!!!

Buen producto, como lo describe

I put this stuff in my car's cooling system as preventative mantinence after a coolant flush. My car then developed a gasket leak. This stuff only seemed to slow the leak down. Use at your own risk.

I used this on a small radiator leak on my '68 Ford F 250 and it worked immediately and stopped the leak. I tried it on a leak around the water pump on my '02 Passat and it didn't work at all. It's a good solution for a radiator leak, apparently, but it isn't a mechanic-in-a-can for water pump leaks. Update: The second time I started the truck after the treatment had stopped the radiator leak, the leak restarted in the same place. It was a small leak, too. So, this turns out to be a super expensive temporary fix for very minor leaks. I was ripped off by this product.

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.

Helpful

This stuff could seal a fist sized hole. Okay that's exaggerating, but, this will seal the worst blown head gaskets. Truly amazing product.

Didn't work for me. Found my leak right at the seam between the top tank and radiator fins. New radiator ordered. 😕

Amazing product.
