Taking it back to him is a no go the car isn't running hot or nothing I'm going to take it to auto zone so they can read the codes other than that I'm lost my car wasn't doing this in the beginning I took it back to him yesterday for the second time I left it came back to get it still the same thing ...

Also the car wasn't doing that before the radiator I need help my mind is all over the place

I got a radiator replacement now water is leaking but when the radiator got put on now my Volvo xc90 just stalls at stops and sometimes cut off. I'm so discouraged and confused at this point the mechanic did what he was supposed to do but why is the car cutting off now like that I'm in tears ...
