    I have a 2010 Prius that has been diagnosed (for sure) with a head gasket that will need to be replaced: coolant is leaking in the pistons. The battery health is not great either. We will buy another car and either sell for cheap this one or drive it until it dies. Right now, the car doesn't even have the check engine light on, and it only shakes a tiny bit on start up.

    I'm considering putting K-Seal into the coolant to extend the life of the car as long as possible. Are there downsides? Here's a website that says that the stuff can mix with pockets of air and then solidify in the engine and cause damage: https://www.kwecars.com/jaguar-tech-centre/coolant-sealants/

    Don't use this glue in your coolant system!!!

    If you're just making short trips around town and you don't ever let the engine heat up too much you can sometimes go years ignoring this problem. Once it starts running really rough at start up you're at risk of damaging the dampener inside the transmission so you don't want to see that error code.

    Yeah, don't add insult to injury, deal with the head gasket. Or sell with full disclosure. I really think that stuff should be illegal, suspect it's used by a lot of unscrupulous resellers.

    If you don't mind:

    1. What's the miles?
    2. Has the EGR and intake manifold ever been cleaned, and if so: at what miles?

    Yes and then sell it quickly. Also say all highway miles.
