I work and do instacart everyday since then and I’ve had no issues ! It's been a month and my car runs just as smooth as it did when I got it. It certainly appears to have stopped the heater core leak with no apparent adverse effects. Had the infamous intake leak so I added the K-Seal, going on 5 years with no leaks.

They did suggest that it could be the head gasket needing to be replaced (which would cost at least $2,000). Does what it says on the tin ❤ really pleased and it sealed the small leak in my head gasket 👍 recommended 👌 The thought of "gasp" pulling the dash and everything in and on it to get to that nasty heater core caused my mind to recoil in horror. I CAN'T RECOMMEND IT HIGHLY ENOUGH!

I had replaced my water pump recently and was burning coolant from a head gasket leak real bad. Make sure you do not forget to shake it, if you do forget to shake it, and you’re fortunate enough to put it in the reservoir make sure you stir it, that said very helpful easy to use, highly recommended. It was not an easy job to say the least.
