99 Honda civic si with gsr swap
keeps overheating I already changed new water pump and all new gaskets

one of me friend says that it can be a cracked blocked and it could also be that the machined shop didn't cut the head in a straight line he says they might have cut it crooked.

what can be the problem?
any help would be appreciated.

 

this doesn't belong in the tuning section. moved.

 

EM1,

Any luck? Have you tried testing the thermostat?

Have you tried flushing the factory radiator?

Does it cool down when you're at road speeds?

Does the radiator fan come on all?

 

Thermostat. Or water pump. Check for leaks by timing belt side

 

also check your fuses

 

The thermostat is new
And also the temperature does drop down when I'm at road speed radiator does kick in also
But I haven't flush the radiator.
