did you burp the system, get all the air out of it.

yah, all that new stuff, big chance of a bigass air bubble in the system

yes we toped of the coolant with the motor running. is there a different way?

mattdel

start the motor, top off the coolant.

let it IDLE up to operating temperature. do not fiddle with the throttle while the rad cap is off.
it could take up to 20-30 minutes for the car to be able to reach 195~ idling... be patient.

once the thermostat opens, the coolant should suck down quite a bit.
keep topping it off until it starts to come back out at you. put the cap on. done.

are you positive the headgaskets were put on correctly, there is a front and a back
