Review: Blue Devil - I would definitely get this again if needed works like a charm.
Review: Funcionó - Funcionó bastante excelente, hay algunos trucos que quizás no sea recomendado o tarde más pero pueden ayudar a que sellé mejor, como esperar a repose totalmente un día con el líquido aún en su interior y volver a repetir el proceso, esperar a que enfríe totalmente (unas 3 horas) y ahora sí hacer el cambio a antifrezze

## Questions & Answers

**Q: Im getting combustion in my radiator,not coolant in oil,will it work?**
A: I had the same issue of the exhaust going through the radiator and I followed the instructions to the letter and so far so good. I've put a little over 8 thousand miles on it since the repair with no issues. I was sceptical at first but this stuff is truly amazing!

**Q: How do I return the product if I have already used it?**
A: You can't.

**Q: If i just replaced my thermostat do i need to remove it, it's such a pia**
A: Yes you need to remove it to use this version, there is another weaker version that you don't have to remove it, that version does not work as well.

**Q: I don't get the "remove thermostat" part. If i remove my thermostat where am i going to plug the hose into? Does it mean to replace it with a new one?**
A: Most thermostats can be removed without causing a leak. I am guessing that yours might be like my truck where the gasket is incorporated into the thermostat. If so, you can probably adjust the time to allow the thermostat to open and replace it afterward. I cut the guts out of mine but it was probably overkill.

### ⭐⭐⭐⭐⭐ Blue Devil

### ⭐⭐⭐⭐⭐ Worked great for my Rover!
*by A***B on 6 June 2015*

This product worked for my car that has a leaking/blown head gasket. BUT this is NOT a permanent fix!. It lasted 1 year, the first time I added this to the water. So had to purchase this item again to repeat the process. This item came in a much bigger bottle so you only need to use half of it. It is very easy to use, Just follow the instructions on the back of the bottle. But one thing I didn't bother doing was removing the thermostat before starting the job, I just emptied some of the coolant from the bottom of the radiator, so to leave room in the water system for the Blue Devil liquid when pored in. It worked 100% for me on my Rover 416, year 1998 It may not work for all, but I suppose its worth ago to save the hefty price of paying for a new head gasket ? No complaints, only praise = 5 stars
