SR, Weird overheating problem...help!?

[MandTPhotography]

Alrighty, first off, the motor is an S13 SR, stock T25, injectors, etc;...

I've got a Koyo Radiator, and two e-fans.


It's about 50-60 degrees during the day, and my car won't stop overheating. It'll be fine driving around highway speed or while it's moving, but when it's idling, the temp needle just keeps rising.

First off, we wired up another fan (Used to be 1.), flushed the radiator, and changed the thermostat, but the problem still persists.

I have no idea whether it's the gauge itself, the waterpump or maybe a leak in the headgasket.

There is a small coolant disappearing act, but I'm not leaking it, I suppose just burning it off. It's a small leak though, so I'm not exactly sure what's up.


Anyone have any idea? I have a new waterpump and we'll be replacing that tomorrow to see if that's what the problem is.



tl;dr - Car overheats after driving, while idling. Flushed coolant, replaced thermostat, wired up an extra e-fan, to no avail. Need ideas.
