Hey iisha, although obvious, 1st thing to check is the coolant level. If it's low, the engine will run hot and the low level prevents coolant from circulating to the heater core inside the car, so the result is little or no heat, but engine running hot situation. The top rad. hose takes hot coolant from the engine, it flows down thru the radiator where it is cooled (w/ help from the fan) and the coolant returns to the engine at a reduced temp. to keep the temp under control, and it's returned thru the bottom hose (the result is the bottom hose should be cooler thant the top. There's more involved than that, so 1st check your coolant level, if it's ok let me know I'll help further. Hopefully the fix is that simple, and it is a rather common problem.

Not always. If you have a KA24E (2.4L 4 cyl) engine, the thermostat is located where the lower hose connects to the engine. I have had to change mine. It's easiest to get to if you remove the power steering pump and set it to the side. The thermostat housing is directly below where the PS pump mounts.

then the water pump must be bad in it .Take the rad cap off and rev motor up if it goes down the the pump is working if it spays of look at the head gasket being damaged .Check and make sure spark plugs are not wet either if one is soaked signs of a leaky head gasket
