overheating only on the freeway under no boost
here is what it does. when i am driving at about 65-70 mph or faster for a while my temp gauge will rise even when i am not in boost. if i open the heater core the temp will slowly drop to normal. my car does not overheat no matter how hard i drive when i am not on the freeway. i have a turbo gsr in a vx hatch. i have the spoon temp switch and thermostat. do i just need a aftermarket radiator or could i have a problem elsewhere??

a completely stock honda cooling system should have zero problem cooling a basic hmt turbo setup. I'd suggest starting small and easy. Replace the t-stat, and rad cap. If the problem persists, then look back to your headgasket.

Re: overheating only on the freeway under no boost
do a compression test, if its not your hg do what turboda6 said and hook up your radiator fan to switch, or if your cheap hook it up to your radio fuse :P one side of my radiator is completly toast (bent fins) from my last turbo setup, it used to overheat untill i started using the radiator fan constantly. It used to go up to 230 degrees now it stays around 165-175 with an OEM therostat! They work miracles

Re: overheating only on the freeway under no boost
id get a bigger rad...i had the same problem after i swapped in my b16 with a turbo. Only got hot at high rpms on the highway, and i know for sure that the hg was good (because i did change it). My solution was to just live with it getting a little hot and not drive so fast lol.
