Because of the high mileage I didn't want the expense of doing a head job, so decided to give Blue Devil a try. 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. 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. This is supposed to be a permanent repair so real proof will be how it holds up over time, including the upcoming winter. 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. I would not hesitate to use it again in the appropriate circumstance, which would for me be a high mileage vehicle, exhibiting symptoms of head gasket failure, having a cooling system that is in good condition. Fully drain, clean and flush the cooling system first, then use the Blue Devil per instructions, additionally driving the vehicle over a few days and a couple hundred miles before draining and adding the anti-freeze back in the system (must be done in non-freezing temps of course!)."
"I took the thermostat out. Flush it with the garden hose. Refill with water leaving room for the 1.5 quarts. Pour SLOWLY the sealer. Let it Idle for an hour. Turned the engine off and let it cooled down overnight. next morning I put the thermostat back. Refilled with coolant. NO MORE ISSUES. I would totally recommend, it's been about 5K miles and no problems."
"My mechanic diagnosed the head gasket as the issue, with coolant leaking into the cylinder and fouling the spark plugs causing a misfire. I drove for about 4 weeks without a misfire until it came back today after about 500 miles...also note that I only would drive this car locally for about 15-20 minute trips max, so I can't say whether this would work for a long highway trip."
"I flushed the coolant by opening the radiator drain cock while the engine was running and refilling the reservoir simultaneously with the garden hose until the drainage ran clear. I didn't want to add it to a full reservoir because very little of it would circulate with the motor running. The good news is that the reservoir tee's into the lower radiator hose which feeds the motor with cooled liquid. I drained the radiator and reservoir (2ish gallons) and added 1.5 bottles of Blue Devil to the empty reservoir which drained it directly into the main circulation."

Their final diagnosis (including a cooling system expert) was that even though this car passed 3 different head gasket tests, they believed this car had a very rare type of head gasket failure, one which if you were to go to the expense of inspecting the head gasket you would not see any problem visually, but that under certain conditions air compression would leak into the cooling system and create a temporary air pocket which defeated the cooling circulation."
"I was skeptical, but the cost to replace the head gasket was way more than the car was worth."
"Solved the milky residue on my oil cap, evidence shows it sealed a small head gasket leak."
"Excellent product."
"My head gasket went out in my truck .."
"I installed the product a week ago."
"Had a pinhole in my heater core, enough to fog up my windshield and fill the cabin with coolant mist."
"The fine print on the guarantee requires a shop to diagnose and replace the head gasket in order to make a claim."
When converting an engine from a water-based coolant to HPC, great care should be given during the installation (conversion) process to ensure that all of the old water-based coolant and water is removed before installing HPC. Has a boiling point of 375 DegreeF and will not vaporize, eliminating boilover and after-boil Generates low vapor pressures, prevents coolant loss, and reduces strain on cooling system components.

I can drive it 150 miles to see my dad and I can use my bare hand to take the cap off of the radiator. When I did my flush prep and fill I changed out my heater core with a new one, new recovery tank, washed out my RAD and blew it out with air and let it dry out. I blew out the engine with air and even jacked up my car on its side and back to make sure all the water is out.... If something does happen to a hose or pump all you have to do is capture fluid from the radiator drain valve and store it in 2 liter soda bottles then put the caps on. Any antifreeze fluid needs to spend enough time going through the radiator so it can pass flumes so you can have the proper amount of heat exchange. When this happens you will see the fluid in your recovery tank go low then rise back. Also I called them up and they stayed on the line with me for an hour so I can pick their brain about this stuff."
"When I took the heater core out I noticed the entire bottom of the heater core had actually split (common problem with this particular heater core)."

We never figured out what caused the issue, but we did do a full oil change and replaced filter and cap with motorcraft products. I’m sure glad I did because what I thought was going to be an injector replacement job ended up just being a stiction issue and now all my issues are gone."
"Truck sounded rough on cold start and would buck until oil got hot, but there were not codes. Truck now idles SMOOTH -- enough of a difference for a couple of my friends to comment on how much better it runs."
"I purchase this to cut down on the stiction issues during these colder months, but this also eliminated the constant black cloud."
"I know my injectors need to be replaced but even at $65 extra per oil change that's a lot cheaper than replacing the injectors."
"Keeps system running smooth in cold weather, and eliminates any striction problems."
"After some research I was hearing it was most likely stiction in the injectors, and that I should try REV X. While the price made me cringe, the price of new injectors made me take the gamble."
"I was experiencing some stiction issues with my diesel truck's injectors and after adding two bottles of REV-X following my last oil change, it has noticeably smoother idle and sound."
"This product really works."
