2003 Cobra gets hot when temp goes over 90 Any New Ideas?

OP
1. Make sure your fan is running at both LOW and HI speed.
2. If you have replaced 2 caps and it still leaks when up to temp, replace the reservoir. The factory ones are usually toast after they have been overheated.
3. If you have a 170 t-stat to swap in, do so, but make sure to change the fan settings to allow the lower temp t-stat to work correctly.
4. Cant speak for your local's weather but running more water will always help keep an engine cooler.

If you haven't found issue yet and have filled from cross over tube and feel you have enough coolant. .

Try a test..

This was what I did that confirmed radiator was issue..

Stock gage bites..but it's kinda good..

Safe to say it sits straight up when normal. .
Up is 180deg to 230deg..if it moves to right you are over heating..

I would see this at idle with ac on...

Only thing that cooled it was running a water hose into grill ..

I could watch temp on scanner fall like a rock down to normal..

Air did nothing..

I'm still on original cap and tank..over heated many times over the years
