BlueDevil Products 00209 Pour-N-Go Head Gasket Sealer - 16 Ounce

02 volvo 238k inline 6 cylinder non turbo. Owned vehicle for 10 plus years. Heater core started leaking, 500 bucks plus for new one so I continued to drive adding water when necessary. Gave up putting anti freeze in it as to expensive and only leaks out. It Got so bad interior was starting to flood, like a lot! It was actually sloshing around. Finally, I bypassed heater core and continued to drive. Then the head gasket blew! Hot Water/coolant was pushing backing up through clear plastic reservoir. Like real bad. It was steaming and boiling over like a volcano. Yep, I continued to drive adding water and using it for very short 3 block trips before it overheated. Went to get head gasket repaired. Got quotes 2500 to 3000! I thought the car was trashed. Wife said take to junk yard. Cut our losses. I saw an ad on amazon and laughingly bought 1 bottle of blur devil pour and go. I followed the directions. Remember I already bypassed the heater core so it wasn;t hooked up. I just ran the 2 hoses together to bypass it. I added it to the top radiator hose and put the hose back on. I ran the car as directed. White smoke pouring out of the tail pipe, puffing, chugging, running on only a few cylinders. I was Completely embarrassed as the neighbors looked on from down the street. It said to run 55 minutes at idle but after about 40 minutes I felt sorry and said this is enough I have to put the car out of its misery and shut it off. I slammed the hood and went inside. Next day about 20 hours later I start the car to move it in the drive. I watched the temp gauge, then I hear a thunk. I watch and it isn't over heating. So I take it for a spin around the block. Its Running good. WTH? Omg did that blue devil stuff work. Cmon no way. DId it really work? What the heck is going on-wht isn't the car overheating? Is the gauge stuck as I hit the dash to check. I am in complete shock! My Jaw is dropping I run into the house. I am speach-less! Honey, Honey, the volvo is back!! Yea right she says No I'm serious! Go for a ride with me-If we break down ill never speak to you again, she says. We went out cruising all over. Car ran perfect. No overheating. No smoke from tail pipe. No chugging, no fumes, etc. I am in STILL IN AWE OF THIS PRODUCT. My issue was very serious and 1 bottle and it worked. I am not getting paid for this and I do not lie. I have no reason to. And I do not wish to deceive my fellow man. All I know is THIS STUFF WORKED IN MY VOLVO, and trust me it was in sad shape. THANK YOU BLUE DEVIL AND TO THE GUY WHO INVENTED IT AND ALL YOUR EMPLOYEES AND AMAZON.

I purchased this back on December 30th, 2010 (my "instant order update" reminded me of this this afternoon) and it worked like a charm. All I had to do was drain a little liquid out of the radiator, pour this stuff in and then top it off with antifreeze (pour-n-go). I had tried Bars stop leak a few times prior to that but it never held up for more than a few days and the procedure for using it was cumbersome (remove t'stat, refill, run for 20 minutes, cool and run for 20 more, etc.).The reason I'm back for another bottle of this, and to take a few minutes to write this review (which I rarely do), is because I'm think I'm due for another bottle. I just checked my water this afternoon and it was a little low so I had to top it off. It's an old 87' Ford Ranger 2.9L and I think there's either a very small external leak somewhere or I'm losing some through the overflow system steaming out that results in having to top off the water occasionally. The odd thing was that there was still water in the overflow, which hasn't been the case since using this, so I was a little suspicious of where the water actually went to. (I've never had to add to the radiator unless I'd let the overflow run dry.) That led me to check the oil fill cap and it once again had evidence of what's commonly called the "white snot". "Snot" is a result of water leaking internally and mixing with the oil and [I guess] boiling to a white, snotty consistency. I've checked this a few times just out of curiosity over the past year and all was fine - no snot whatsoever. What I "think" has happened now is that during the course of toping off the liquid over the past year, the original antifreeze and the original bottle of this sealant had been replaced by attrition and the internal leak is back. The beauty of this sealant is that it not only seals the leak, but stays in the system to keep it sealed (and mine had been lost in attrition).Again, this is an old truck and I'll gladly pay $35.00 for a bottle of this stuff [annually through attrition] rather than pay $1,700.00 for head gasket replacement. I also plan to flush the cooling system and the oil system and replace with fresh antifreeze and oil... and a fresh bottle of this stuff. Should be fine once again.
