It overheats when I drive it, but when I put in neutral it goes down to normal. but it will go up within 2 to 3 minutes. I changed the water pump, thermostat, new radiator.

Hello,

This could be a couple of different things. This could be a problem with corrosion and scale in your vehicle's cooling system clogging the system and making the coolant hard to circulate. In this case I would recommend a flush and fill. Here is a link describing how to do that:

Another thing you might want to check is to make sure that the serpentine belt is tight and not slipping. This would cause the water pump to not spin as fast as it should letting the engine warm up and overheat. Please check these out and get back to us with what you find out.

Thanks,
Alex
