I unclogged the heater core in my car with 2 tools. A water hose and a jet nozzle or water ballon spout. The entire process took me less than 30 minutes and then the heater staring working like brand new. Once I was done, my car blow hot air once again. Now my heater works perfect.

If you ever use a head gasket seal and your heater core becomes clogged, then this will fix your problem.

It has been 5 months and my Cadillac Sts is still running just fine.
