[Update 8/22/2024]
With the most intense summer heat starting to wane out here the southeast, my Prius has officially gone 30,000 miles since this solution was applied. The car is still working fine and the check engines it was frequently getting are a distant memory. That is still only a fraction of the 200,000 drive miles I expect to get out of the car, but so far, so good.

Once again, I have another 3rd Generation Toyota Prius that has a blown head gasket. While I can only speculate as to why this generation is so prone to this problem, the fact is I elected to deal with it by applying K-Seal. The shake & pour solution cost $15.99 plus tax. Once again, I have back to operating the Prius free of check engine codes, hard idling, and ever dropping coolant reservoir levels.
After nearly 6,000 miles after applying this 3-minute solution, I am going strong. Please post your questions.
