How about some info on your car to start.
What year is it?
How many miles on it?
Service Records if any?
Mothers maiden name?
English teachers name so we may have her fired!

- insufficient coolant ...
..... external leak: radiator, heater core, hoses, water pump, thermostat housing
..... internal leak: blown head gasket, cracked engine casting
- coolant does not circulate properly ...
..... stuck thermostat (stuck closed, or unable to open fully)
..... bad water pump (loose impeller, worn impeller vanes)
..... bad radiator hoses (outside may look okay, but inside has collapsed)
- obstructed radiator ...
..... external debris (road trash, insect bodies)
..... internal deposits (corrosion, minerals from water, coolant additives)
- failed electric cooling fans
- bad temperature sensor (cooling fans don't turn on)
- air pockets (air trapped in cooling system)
- faulty radiator fill cap (unable to maintain pressure)
Less likely causes ...
- obstructed exhaust system
- improper ignition timing
- lean fuel mixture

Probably bad temp sensor so the fan doesn't turn on. When it's overheating, pop the hood and look at the radiator fan. Is it turning? Don't let the car over heat into the red zone. You are looking at cracked heads or head gaskets when you overheat the car. That's a over $1K worth of repair bills.

Taking from DBM's suggestions, if replacing the thermostat and a radiator flush hasn't helped your overheating problem, I would check the cooling fans. 4th gens have two cooling fans. One cycles on and off when engine temp rises and falls. The other turns on when the AC is activated, or if the engine temperature is hot enough such that the second fan is needed (after the first fan is already on).
An easy way to check for proper fan operation is to drive your car until the engine reaches operating temp, then let it idle for a little it. The first fan should turn on. Now, turn on the AC...the second fan should turn on. Now you know whether both fans work or not.

The problem started like a month ago, it’s 95 Maxima GXE with intake, exaust, 18” Racing Heart C5’s
Sprint springs and it has 52,634 miles on it. The car runs great for like 25 min and then it moves up slowly to the redzone and then I put my heat on and it gradually goes to its normal spot on the gauge. The mechanics now are saying it might be an air pocket problem inside the radiator that doesn’t allow the thermostat to turn on and I don’t know if that could be possible to cause the engine to over heat.
Thanks again guy's
Sorry for misspelling so many words on my first reply, I was in computer class and my teacher was around the corner and I replied in a hurry

Your right it could be just that. I had a Prelude and I experienced it twice, both times after I did a flush. It was very hard to get the system to work correctly after it was done. Definately was air, even the factory manual said this and told you where the bleed valve is. I don't have the manual but DBM perhaps does and can locate it for you.
Good luck.
