Now they want to test my head for cracks, or they think its a blown head gasket. Im calling
and I'm thinking something more along the lines of a thermostat or water pump issue.

y dont u test the thermostat for proper operation? check your radiator cap as well... it could be that the radiator cap is not outputting the right pressure and is decreasing your coolants boiling point causing it to overheat much faster...

There is another bleeder at the front of the intake manifold.

If there was no issue before the coolant change, then its coolant bleeding issue. Bleed it again.

Bleeding the S can be a bitch. Many threads about it.

Check the "fix" in this one. Click -> still over heating, only when I put the heat on

Hmm I was thinking it could be the thermostat aswell. I did replace the radiator cap on my koyo rad. Perhaps its not giving enough pressure. I'm thinking I might order an upgraded thermostat, radiator cap and fan switch while I'm at it.

Almost always due to air pockets in the system, need to crack bleed screws and let steam escape. Should work alright after this.

Use the valve that SplitfireS outlined first. Not sure if the second one is for the coolant, thought it was for the AC. Need to check service manual.

Had similar issues with mine when I changed the rad.
It's worse on RHD cars as the back bleed nipple is not there.
In the end I found it easier to jack the front up and use the bleed technique above!

I'll have to try the "fix" stated in that other thread out once my spoon thermostat comes in. I'm also wondering if the honda type 2 coolant was used. I'm betting not. I think I'll get some of that aswell since I believe I will have to drain my coolant anyway to put the thermostat in?
