coolant on the ground

[Kulasstar]

so about a month ago i replaced my radiator becuase of a coolant leak. so far so good. until today. i used my AC for about 20mins on a ride to get a drink. parked my car and coolant was spilling out from the radiator. from the top of the expansion tank, for the drain plug, all over. there was also some smoke coming up from along the firewall side. what could cause this. it there a clog somewhere. any info would be greatly appriciated. im very frustrated with this already. thanks in advance.

Did the car overheat? sounds like pressure in the cooling system was trying to escape...

Could just be low on coolant. Refill it, bleed all the air out and cross your fingers.

Start with what the others suggested... and pray you don't have the same problem I ended up with.

If you suspect something like my situation, have the same test done like I did where they checked for exhaust gasses/pressure building up in the cooling system. It doesn't take them long to find out (atleast in my case) :(
