Review: Worked on a motorcycle. - I used this on a 35 year old Honda VF500F motorcycle that was burning a small amount of coolant, It is very difficult and expensive to get new head gaskets (and taking one of the heads off the engine is not an easy job to begin with). The cooling system capacity on my engine is about 2 quarts, so a little went a long way in my case. The bottle is supposed to treat up to 6 gallons, so I used about one ounce to treat my engine. I also removed the thermostat. Other than that, I followed the instructions on the bottle. I flushed and filled the cooling system with just water, left the radiator cap off, and ran the engine to operating temperature. Then I added an ounce of seal-up and capped the radiator and idled for 20 minutes. There was a big reduction in white smoke, but it did not go away entirely. I shut the engine off, let it cool, and drained the system and let it sit for 12 hours. I repeated this process a second time, but on the second time I noticed no white smoke whatsoever, so one treatment must have worked just fine. I drained the system and let it sit as before, then flushed the system the next day. So far everything is working as it should. No leaks! If you are considering using this on a motorcycle head coolant leak, because parts are hard to find or replacing the head is not easy, it worked in my case, and it is a cheap and easy workaround. It is not a replacement for doing the job right, but spending hundreds of dollars on a motorcycle that is only worth... hundreds of dollars... isn’t a good investment imo unless it is a highly collectible bike.
Review: 5-Star product - Very goood product. I help fix my brother car with White smoke coming out the tail pipe. We check to make sure we have enough engine oil before we do this thing. We REMOVE THE THERMOSTAT. We flush out all the coolant inside the radiator and engine. This product will only work with WATER ONLY. We refill with water from the garden hose. Then we leave some room to fill this whole bottle in. We ran and idle the car until the temperature gauge and the fan come up for good 20 to 30 minutes. Then we turn off and let it rest and cool for 15 minute.. Then we start up again for 30 minute to let it idle to circulate the system with this chemical and we drove for 10 minute. We FIX the symptom from there. White smoke did not come out anymore. Notice two things we do here, we Remove the THERMOSTAT and fill the system with WATER ONLY. VERY GOOD PRODUCTS. This stuff can only be used with Water to seal. If you used with coolant then it won't seal as we know it. That's why you got to flush out all tge cooolant and fill with water Only. Also if you car has water in the engine oil distick, then I think you are having a bigger problem then this thing can fix. This will only works with engine that has White Smoke coming out the tail pipe and not having bubble of white water inside your engine dipstick. Those are the two major factors you have to know before you complaint it's not working.

## Questions & Answers

**Q: what are the instructions**
A: First off this works good but mainly on tractors without a heater core for cab heat. It only seals minor holes and very small cracks. You'll want to drain the system. Then run a flush treatment to remove whatever contamination. Then fill with water only and pour this sealer in at the same time. Never pour this in first. Then run the vehicle or tractor for at least ten minutes or so then let it cool completely. Overnight is best. Then drain the system. Then fill with only water and run it again then cool it. Then drain it. Then fill with coolant and water. Make sure you get the air out of the system during each refill. It worked for me. No leaks since using it.

**Q: Will it be enough for six Cylinder?**
A: Yes I've used one bottle for 6 cylinder

**Q: Will this clog the bleeder valves on the engine ? I’m worried they won’t won’t after this.**
A: My Boyfriend who bought it said Yes it can. He is a mechanic and was used for a cracked engine block, so he said if it can seal that, it can clog the bleeder. Hope this was helpful.

**Q: does this stuff fix head gaskets?**
A: You won't believe how well it seals a blown head gasket. I still don't. I'm 90% sure I cracked the head on my car and this stuff sealed it up. I never want to try to tear that engine down- nothing will ever come apart! I was amazed and I am sure you will be too.
