Could be low on coolant, or a flow problem such as a sticking thermostat.

u gut tadu a dye test on the ac--a good mech will inject and spot a color under a lite

Heater coil

Defective hose?

Stuck thermostat maybe?????

is it sezeing up then??? or a throttle problem?

try the thermostat first if its not that SELL IT lol the head gaskets can cause it to over heat so will cracked or warped heads if you drive it to long overheating ( if it is )
you can do alot of damage to the engine GET IT LOOKED AT this can some times be very costly to fix

It could be an air leak. Check for bleed valves in the cooling system on top of the engine.

Old hoses could have collapsed internally. Replace radiator hoses.

Check connection to temperature sender- could be gauge.
