It is definitely NOT normal. The valve is intended to stay closed until manually opened. If it were to open, it would lower the boilover point of the coolant - the system is supposed to operate at 13psi.

I suspect that:
1.) you did not get the right part
2.) the part is defective
3.)you installed it incorrectly
4.) you didn't close it correctly

Cheers!
