Hi

I know Ive seen this problem on here before, I tried searching several different terms and either didnt get what I needed or found an insufficient answer. So Im F'in sorry in advance.

I have a 94 civic beater. Bone stock. Im also in Texas and its been like 106 everyday. The damn thing is overheating at idle, after its been running for about 30 minutes. I checked the thermostat, new cap, checked flow and flushed the system, checked the timing, checked for a blown head gasket, the fan runs great....everything checks out fine.

Everything points to the radiator not being enough for the heat here. It acts fine when its 99 or 100 degrees outside. It only overheats when its this hot and there is no airflow onto the front of the radiator. So I'm thinking get a radiator with a two row core.

A couple of things hold me back, one I used my radiator from a D series a few cars back on a B series swap and it worked fine. Two is that Ive seen this problem mentioned several times but without an answer, so Im wondering if there is something Im missing.

The only thing I can think of the would possibly be causing this, other than the radiator is too weak, is a faulty distributor that could be advancing my timing.

Any wisdom on this bullshit?
