It's a 94 gsr motor in a 92 cx. I'm using the cx radiator, and i'm wondering if that's the problem.

Today on the way to school, going uphill on the freeway, the temp. went about 3/4 and was inching it's way to about 4/5.... pulled off the freeway and it came down.

the fan comes on, city driving it's surprisingly cool, no leaks.... the thermostat is working good...

I just changed the coolant, replaced the fan with the fan from my old 01 gsr...

recommendations? i'm going to change the radiator as soon as possible, I was looking into the GSR, but we're installing the turbo in a couple of weeks, so there might be a clearance issue?

 

Check your timing too!!

 

yes, get a dual core radiator, and check your ignition timing

 

Not enough coolent, when at an angle (uphill) engine doesn't pull enough coolent.

Clough in lines; you might want to "super" flush.

You didn't unscrew bleed screw when filling.

Few things to check for.
