My 1995 Chevy Lumina is overheating, about a pinky's width from 260 degrees, and the radiator is fairly new. I have a high flow air intake would that effect this? Is it the water pump? I see no leaking even after a day or two of being parked. I need help a.s.a.p. Thanks for any opinions.

If you stay cooler with freeway speed but hot in city...that would be the fan not working.
Next would be the water pump going out. The impeller seems like it's worn.

mine did the same thing so when i was in the city i would take it out of overdrive and that would help a little. And then one time i changed the oil at the 10 min place and then it was a lot better. Then a few months later i saw a huge cresent wrench laying on one of the electric fan blades so it wasnt able to turn. After i took that baby out of there it worked just fine and never overheated again.
But i would check the fans, And the thermostat

Well, how's the coolant? In most modern auto engines there is a fair amount of aluminum. This is protected from electrolytic erosion by the coolant, as there are "corrosion inhibitors" in that slimy green stuff. So first thought is change this often. I used to do mine every few thousand. 10,000 + per change may not be adequate and the damage is not something that can be corrected with a change of heart later on so keep it up.
You could need a new thermostat. Your pump could be being naughty. Etc.
Get a new car.

It's not overheating if it does not go into the red zone. The car engine needs the electric fan to cool radiator at slow speeds or stop and go. It is going to get kindof hot before that fan turns on. Your pinky width sounds normal.

I'm sure that your problem is radiator fan (ventilator, blower).
You can test it this way :
Leave your car runing but not moving for some time (10-15 min). When temperature starts to raise, ventilator should start working and you will be able to hear or see this, in contrary your ventilator is not working!
While you are in city there is no enough air flow to cool your radiator. This is the moment when your ventilator should cool your radiator (engine). You should visit electrician who can resolve this problem, it is rather simple.

well it could be the thermostat,
but before that make sure
1. the fan is working
2. the radiator has water/anti-freeze
3. the hoses are bot broken.
if the above 3 are fine then the thermostat is the problem
else one of them

I believe you have a thermostatically controlled fan. Next time your heat indicator shows overheat, make sure the fan is working........if not, it could be a blown fuse or relay.
