When your car is cool, check the coolant level. You could be low on water.

When it's running, when it starts heating up. Feel all the hoses and squeeze them. They should be warm or hot, and you should be able to tell if there is water in them. If you squeeze one that squeezes really easily, or isn't hot, then there probably isn't water in it, and that's your problem. But since you changed your thermostat that's a bit more unlikely now.

If I cant think of anything else to add I'll edit my answer.

You might also check your cooling fan switch. this switch activates your cooling fan to turn on at a certain temperature. which is normally located on the thermostat housing or on the radiator itself.

Check your hoses ... if your hose is not firm when it is cold you have bad hoses that could lead to a pin hole ... however, your coolant level will let you know if you have a leak ... as well check your hose clamps make sure all are secured properly ... and one finally idea ... check the radiator itself... make sure you do not have a pin hole in that ... you can get some short term fixes for those at your local parts stores.... I do not suggest it .. if you can afford the repair do the repair .. but hey I have been broke before and sometimes you have to do what you have to do ...

Good Luck I hope that you get it fixed!

Check the following;

1. low level of coolant

2. coolant leak

3. water pump starts to malfunction

4. clog radiator

5. fan not working properly

Have these things check first. Hope this help!
