Worked as label claimed. Be sure to follow directions about flushing radiator out. Be sure to put in the right amount for the gallon size of the radiator. So far so good. Been about a month of regular driving. I think my problems began with the fan clutch then the water pump. If you hear strange noises then check those, the belt and water in radiator

Car - 1995 Honda Civic 1.5L Automatic Miles - 200,000 plus Problem - Had a blown head gasket, blew white smoke out of the back and had an intermittent misfire. Results From Using Blue Devil - I followed the directions exactly, removed the thermostat, drained the coolant, put in water, added the correct amount of blue devil product, ran the engine at idle for slightly longer than instructed which ended up being 1hr. The white smoke did go away substantially but it was still there. Still had a slight misfire every now and again but not as frequent. Problems/Issues - After using the blue devil product I ended up having a major water pump leak right after the 1hr idle time. Not sure if this was due to the blue devil or not but it seems suspect. Credentials - Master ASE Certified Technician/ Shop Owner. Recommendations/ Future Thoughts - I would definitely recommend doing the job right and replacing a blown head gasket before using any “bottle” fix. However this was a good option due to the miles on the car and the lack of funds available from the customer. I was impressed that it actually made a difference in the coolant consumption. I am going to replace the water pump/timing belt next and re-add the remaining bottle of Blue Devil when I refill the coolant again. Hopefully it just continues to get better as it works its way through the system. Read full review

Bought this kit for a heater core leaking and old motor that had been sitting for a while, Installed as directed with flush and clean water, then as directed put in sealer and worked great no leaking heater core and car runs just at right temp. Easy to use and great product, have used Blue Devil rear main seal in my hotrod with a real bad leak and sealed it right up, nothing better on the market hands down.

Have a 07 Subaru Legacy that started getting coolant in the oil. Didn't have the money for rebuild or new engine. Decided to try this as a last resort. I was using 1-2 quarts of coolant every 2 days. Followed the directions on the bottle. Been 600 plus miles and 3 weeks and hasn't used any coolant at all. I would definitely recommend this product and use it again.

It will buy you time. 6 months the first use. for me. We shall see how long the head gasket holds this time. Bottom line, an old work car can keep on going. Nothing to lose if the head gasket is blown. Worked well enough for me. The better the flush the better the hold. I left some in the system after refilling with coolant to fix any small cracks in the seal that may form.
