My 1999 Pontiac Montana is leaking antifreeze. The temperature is going up and then go back down. The dashboard is cracked. It is running sluggish. I triedputting sealant block to help but nothing is working. It is shaking when it is sitting still in park. What could be the proble?

If you have a check engine light get codes read.

Have compression test performed to check head gaskets, if OK, then perform a cooling system pressure test to isolate leak.
