Replaced thermostat and water pump but it don't just over heat sometimes it's gets in the red and then drops back down

Cheap try is new radiator cap. If it cant pressurize the system the boil temp lowers considerably. If put new cap on and still over heat could have bad head gasket or a blockage in radiator...Cap is common and 10.00 to fix....

Have you shop perform a "leakdown test." You probably have a bad head gasket )or a leak in the gasket).

check your radiator fan if its powering on when engine runs hot. Test if there is power at the fan's electrical connector when car is running and temp guage is at half. If there isnt any power on, check your relays and fuses. Hopefully this helps

Start the engine when cool, remove rad cap and start engine and let it run with the heater on. (not defrost) Top up coolant as needed in rad, and let it run until either the rad fan comes on and off 2 or 3 times, or you can see increased flow in rad from thermostat opening. It will obviously happen after it reaches operating temperature, so watch after gauge gets close to there. Wait until you see that flow 2 or 3 times or fan comes on and off before you put cap on, and fill return bottle to proper level as well. That should cure it, by getting air out of system, and coolant flowing through heater core.

Are you losing coolant. If you are I would check your heater core which is located under the glove compartment.
Overheating can seriously damage a car's engine if left unchecked. Although overheating simply means that a car's engine temperature exceeds normal operating temperatures, the causes of overheating are varied. What follows is a brief list of some of the most common causes of engine overheating.
