Engine keeps overheating after I have driven maybe an hour and a half. I have changed water pump, thermostat, sensors, and fan relays. What else could it be?

Hi and thanks for using 2CarPros.com.

Overheating can be caused by a few things. You have already replaced the components related to it. With that in mind, we need to eliminate other potential issues. First and easiest, if you have not already replaced the radiator cap, have it checked to make sure it is working properly. When the system pressurizes, it increases the boiling point of the coolant. Also, if you have not already, you may want to consider flushing the cooling system. A build up of corrosion in the system can block water ports causing an overheating problem. Here is a link showing how it is done:

Next, confirm there isn't a bad head gasket. Here are easy directions for checking:

Start with that and let me know what you find. If you have questions or need help, let me know.

Take care,
Joe
