A few days ago I noticed a puddle on the ground under my 2004 Jeep Grand Cherokee. Sure enough it was antifreeze. I ran the engine, shut off the ignition, and took a look. There was a fine stream spraying from the upper section of the radiator, onto the engine and serpentine belt. I went on line and started to read reviews about radiator sealers and the k seal brand seemed to stand out, so I thought I would give it a try. I went up to Auto Zone and looked over the selection, and discovered that K seal was about twice as expensive as the other brands, but I figured that you get what you pay for, might as well get the best. I put it into my radiator in the parking lot, then took a 20 minute drive. When I got home I shut off the engine and took a look. To my amazement, the leak had stopped! It has been a couple of days now, and if the leak comes back, I will write another review, but for now, it was worth the extra expense.
