LS cooling question..

[yukio]

Fans are controlled by ECU and they are pulling the right way. If i dont remeber correctly they are set to start at 185 and turn off at 180.
The 160 thermostat was just an attempt to get it to open earlier and therefore run cooler. I have a 180 thermostat laying around, wich i will use if i get it to run normal.
When the temp is passing 210 i am stopping the engine. With a 160 or even a 180 thermostat it should be running cooler than that?
Steam vent is connect to the cross between the heads.

I have been running the car for a week or so now. Running several rpm pulls and several heat cycles, so it find it strange that air in the system is giving me these problems. I have topped the radiator several times, and now it cooolant level does not decrease anymore. I have probably about 3 gal in it.

The wierd part is that the cold side of the thermostat is "ice cold".
The thermostat is definitely not opening as it should, and when touching the radiator only 10% of it is actually hot.

I might be trying one of my other thermostat an see what that gives me.
