So just put turbo back on and new half size dual core Megan racing radiator.

On the highway and get off within 5 min water temp shoots up to 3/4 of the gauge range basically 75% hot. Not sure why this is happening been an issue off and on for sometime but only seems to happen with the turbo on and running a half size civic radiator.

When installed the new radiator bled the coolant until the heat blew hot but might still be some bubbles in there. I know other Hondas have a bleeder value on the head not sure if this can be installed on Integras but would be good to do.

Think should be bled enough it the air blowing hot not really sure what else could be causing this aside from maybe a bad thermostat but if that was case it should be overheating all the time not just when getting off the highway.

 

Drain plug on radiator vibrated loose and started leaking coolant but at a slow enough that didnt notice until it was all basically gone.

 

Sweet...Air to air radiator
