93 mazda protege overheating

i have a 93 mazda protege runs fine. When I'm in slow traffic the temp goes up to almost over heating. If I pull over and put it in park then give it gas revving the engine. the temp drops down to normal. It will also drop to normal if the traffic breaks and I can give it gas to go faster. Any ideas?

Bet the electric fan(s) is the culprit. Take a look and see if you have A/C if the fan also could help the radiator. Sounds stupid but if so the A/C mode should force the fan on and don't ask for much cooling but it may bring the temp down till this can be fixed properly.
You don't wan't to add damage if avoidable at all, T

the a/c does not work... how can it be fixed? Just replace the fan?

That's a 40,000 dollar question! What about it doesn't work. No condenser fan, low on refrigerant, no cabin fan, compressor not engaging etc etc. It is separate from engine cooling except maybe a common relay or fan underhood could cause both to not behave. More info on your observations would help, T

I'm not concerned about the a/c. The car getting to the over heating stage and then when you rev the gas it goes to normal, is what I want to take care of. You mentioned the a/c fan might not be kicking on. would the a/c not working affect the cooling system?

A/C should not effect cooling system. Basically you are welcome to leave it broken with the exception of any belts it shares which should only be pulleys and the car doesn't care whether it's able to make cool air for you.
The car is still supposed to turn on an electric fan for the cooling system for engine whether it had A/C or not. The symptoms as I've read seem to lead to that fan not coming on and I mentioned A/C as it's always on with that request and the regular mode would be as needed by engine heat.
Since this happens at low speed which is when the radiator needs help with air flow it points to that fan and what controls it.
When in motion the air flow of just moving is usually enough. When stopped in a traffic jam or any real slow driving it needs the fan.
Got to know if that is working or not to go much further, T

Sometimes, especially with Mazda, something as simple as changing the thermostat can do the trick. If they get sticky, or the spring gets week it takes more water pressure to move the water through. (hence reving the engine will cause it to cool) DON'T SIMPLY REMOVE IT! On a lot of the new engines, when the thermostat opens one hole, it closes another at the same time. They aren't that expensive, and usually pretty easy to find on the car.
Good luck... with the previous posts.. there are a number of things that could cause it.. Start with inexpensive and simple, then go from there...
