Customer Testimonials
“My 1999 Nissan Pathfinder developed a bad passenger side head gasket leak with coolant streaming out under the vehicle. I found Irontite All Weather Seal, bought 2 bottles and poured one in the radiator. The leak stopped and still going strong at 1,000,000km 2 years later. I still carry the 2nd bottle ‘just in case’, but I’m sure I’ll never need it.” ~Doug
“So far so good! I did the flush with Irontite Thoro-Flush followed by 4 rinse cycles to clean everything out of my system, and a lot of nasty stuff came out on the rinses. It works great, you just need to flush the system with water a few more times after you are done to get everything out. My system is running much cooler now.” ~Irontite customer
“Irontite Thoro-Flush is a life saver! I messed up and added green antifreeze to the red in my ‘06 Tacoma, clogging the heater core and the radiator. I dumped the antifreeze, flushed with distilled water and used the flush as directed. After 3 years I have heat in my truck. I highly recommend this product!” ~Irontite customer
“I tried Preston’s and GM’s flush for getting rid of dexcool sludge, but the car kept overheating. Irontite Thoro-Flush got a whole bunch of dexcool crap out. Now the temp is back to normal and I’m not loosing coolant from overheating. This is no ordinary watered down stuff from department stores. Truly commercial grade.” ~Irontite customer
“My ‘97 Gold Wing bike had a water leak in a plastic fitting. The Honda shop said that no additive would work and it would cost $200 to fix it, but I put the Irontite All Weather Seal in anyway and it stopped the leak. This motorcycle must-have works great!” ~Deb
“I’ve been using Irontite Thoro-Flush in my shop for years on cast iron engines. There isn’t a better product for flushing cooling systems in cast iron engines.” ~Will
