Review: Car running great, Blue Devil has worked as promised 2 YEARS and still going! - Here's the scenario: 2003 Nissan Altima 2.5 liter, 175K miles on it. Symptoms: Losing coolant, about 8oz a day, but no external leaks. Had a problem with heat going back to last winter - there is no heat when the engine is at idle, the engine has to be around 2K revolutions or higher to get heat from the heater core. This is because there is combustion gas constantly leaking into the coolant system creating a vapor lock in the heater core. Engine has occasional misfires in cylinder 3, I believe caused by coolant leaking into that cylinder. If the radiator is running under pressure the engine sputters and struggles to run at times - I believe because an over-pressurized coolant system is forcing some coolant into the engine. Setting the radiator cap so the radiator doesn't pressurize, the engine runs fine. Replaced both thermostats (yes there are two for some reason) and made no difference. Given those circumstances I was very certain there was a head gasket issue. Because of the high mileage I didn't want the expense of doing a head job, so decided to give Blue Devil a try. I followed the instructions on the bottle to the letter with these exceptions: (1). Idled the engine with the Blue Devil mixture in it for 80 minutes, not 50 as the instructions state. After letting the engine cool overnight and starting it, it was rough getting it going and it sputtered a bit at first. This led me to believe that the mixture may have bled into a cylinder while under pressure and the car not running. So: (2). I drove the car for 3 days, about 200 miles, with the mixture still in radiator and thermostats out, to give the pure mixture more time to seal any leaks. (3). After 3 days driving I drained the coolant down, keeping the liquid, put the thermostats back in, then added enough anti-freeze for a 50/50 mix. Topped up with the Blue Devil/water mix and bled air out of the system.. It's now been over 2 weeks since I used the Blue Devil, I've driven about 1500 miles including a day trip of around 400 miles. Engine runs great, there are no misfires, no loss of coolant, no excess pressure and there is ample heat from the heater core with the car at idle. So at this point, problem is 100% fixed. Blue Devil did the job as advertised and I'm a happy customer so far. This is supposed to be a permanent repair so real proof will be how it holds up over time, including the upcoming winter. I'm hoping to get 2 to 3 more years from the car, until the car I just purchased for my wife is paid off and I can afford to replace this one. I will update this review as time passes so keep tuned, but so far, so good! **UPDATE** - October 3 2016, going on 2 months and over 4K miles driving after using the product. Car continues to run great, no indications of any head gasket issues. I've driven the car on 2 trips, one 350 miles and one 750 miles at speeds up to 80mph. No problems and am getting better gas mileage on the trips than ever, 31 to 32 mpg highway. **UPDATE 2** - January 5, 2017 - it's now been 10K miles since using the product. Still no issues at all, no coolant leaks or loss, no air or combustion gasses getting into the coolant system. Prior to the Blue Devil repair, air/combustion gas would be trapped in the heater core meaning no heat inside the car unless RPM's were very high. Now there is no problem with heat, even at idle the heat blows strong. I'm sure results of using the Blue Devil Gasket Sealer may vary depending on the type and extent of damage to the head gasket, but in my case it has resulted in an effective and very cost-efficient repair. **UPDATE** - August 21, 2017. It's been one year, 21,500 miles and I've had no problems with the car at all. Running great, no coolant or head gasket leak. **UPDATE** - July 13, 2018. 212,000 miles on the car, 37,000 miles and 2 years since I added Blue Devil. Still no issues, not losing any coolant, car runs great. 2 years of driving this car on a 60 mile/day work commute plus personal driving miles. **UPDATE** - July 5, 2019. 233,000 miles on the car, almost 3 years and 58K miles since Blue Devil was added. A few weeks ago I noticed my coolant level was slowly dropping. No external leaks so it has to be internal. I've wrapped a paper clip around the internal radiator cap seal so no pressure builds in the cooling system, coolant level is now stable. There is no evidence of combustion gases in the coolant, however there may be issues developing, I will monitor closely. *Sep 8, 2018 - turns out a small bypass hose to the throttle body had a slow leak that dripped onto the transaxle housing and collected in a small area that evaporated before it dripped to the ground. The leak got worse and I noticed it, replaced the hose and now there's no coolant loss, so no internal leaks. Engine is still running good.
Review: If you have an odd emotional connection to a 1996 Subaru, THIS product is for you! - Bought my 1996 Subaru Outback Impreza new off the lot during its birthyear (96). Since then, it has taken me through a dozen or so states, two wives, two kids, two dogs, five cats, and around 75 chickens. I've hauled trailers, firewood, camped from and lived out of this vehicle (the latter being a temporary homelessness between graduate schools). I had the head gasket replaced after around 140k miles ... about 15 years ago, and over the past year she wouldn't start again after running without a 20 minute rest. I've basically rebuilt every pump, filter, belt, and other doo dads myself, but a head gasket is beyond my ken. I should also mention I coated the vehicle with two layers of black semi-gloss housepaint after 200K miles ... she's not much of a looker but has always gone forwards and backwards, all the windows still work, as well as heat and AC ... When she started overheating like mad three months ago, I took her to my local mechanic who said he could do the head gaskets for "cheap" at around $1600, if he were to do it right and machine the heads. The car is worth less than $400 on paper (the tires are literally worth more than the car), but ... it's like putting down your favorite dog. I got to shopping for a new/used Honda, drove my motorbike to work for a few weeks, and prepared myself for the worst. THEN! I stumbled across this magical fluid, which still seems too good to be true. $50 for a functional vehicle? I figured it was worth a hail-mary, and had some delivered. While waiting for its arrival, I did tons of research - the odds seemed about 50/50, but worth a Saturday afternoon given our history. I followed instructions EXACTLY, flushed the radiator, etc., pored in half the bottle, ran it for 45 minutes and prayed for the best. Next morning she got to work, but just barely - I had to run the heat full blast to keep it from blowing up, and the radiator reservoir was bubbling over like mad (not a good sign). I came home despondent and wondering what the chances were of me doing a head gasket repair in my driveway ... ran across some reddit threads, and followed some random advice that said sometimes it takes more than one application. So without even removing the thermostat, I chunked the other half of the bottle in the radiator and figured it couldn't hurt at this point. Ran it 45 more minutes and ... The next morning she made it to work without overheating at all! And over the next 3-4 days, she seemed to be running BETTER every day! Lo and behold, the thing will now crank up every time without a cooling period (I have NO idea how it fixed this issue, but don't really care). After a couple months, it started to overheat just a tad bit and didn't restart for ten minutes while running errands, so I got another bottle, dumped half into the radiator, and ... viola! Hell, even if I have to toss a bottle in there every three months or so, that's $20 / month, which by my calculations is much cheaper than a car payment, and I get to keep my OldBaru :) I ended up buying a 2023 Honda CRV for highway / roadtripping, but purchased a cover for it & it sits under wraps in the driveway for 2-3 weeks at a time, as I keep the miles off it by rolling in the Subie whenever possible. Thusfar, I've had her on the road for up to 90 minutes with no problems, but I'm wary of taking her out for much longer, and don't need to anyway with the Honda in reserve. Long / short - this stuff actually works, but you may have to tweak the directions / application a little bit. It's a win-win if, like me, it's either the magic fluid or the scrapyard :) Good Luck!

## 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.
