Where is the thermostat on a 1998 Chevrolet Cavalier?

I am trying to replace the thermostat and I also would like to check to ensure the coolant is in the radiator. However. I cannot find the cap that's directly connected to the radiator.

GM took new design to move the thermostat closet to bottom radiator hose BEFORE THE WATER PUMP (rocket science on DRUG) Look down by the exhaut pipe between the alternator and exhaust pipe, there is a radiator hose running into a housing that runs into the lower block. Take off housing that 2" hose hook up to and you will see that the thermostat IS in there. They should of never design it this way because the thermostat closes to early letting the engine stays too hot ( the thermostat SUPPOSE TO BE AT THE HEAD AREA ((AFTER THE WATER PUMP--NOT BEFORE THE WATER PUMP)) IDIOT DESIGN!!! MAKE A HOUSING OF SOME KIND WITH TWO 2" MALE ENDS AND MOVE THE THERMOSTAT AT THE TOP OF ENGINE HEAD AREA BEFORE THE RADIATOR BY CUTTING UPPER RADIATOR HOSE AND ADDING A BOX OF SOME KIND THAT WILL HOUSE THE NEW THERMOSTAT THAT RUNS INTO TOP OF RADIATOR (WHICH IS THE REAL HOT AREA--THAT WILL KEEP THE ENGINE AT CONSTANT 180 DEGREE AND NOT 200 PLUS DEGREE CAUSING EARLY HEAD GASKET FAILER! USE ORANGE HIGH TEMP GASKET SEALER AT OLD THERMOSTAT HOUSING AND LEAVE IT OPEN TO FLOW FREELY AND LET THE NEW THERMOSTAT DO THE REAL JOB THAT IT IS SUPPOSE TO DO... I AM SHOCK THAT SOME IDIOT WENT AHEAD WITH THIS STUPID DESIGN!! URGH

There probably isn't a radiator cap. some cars only have a cap on the resivior tank. if your coolant is low, it'll show in that tank. follow your upper radiator hose to engine. thermostat should be at the end of it, depending on what engine you have

I have a 98 cavalier and it keeps over heating any pointers

First, look for leaks and make certain your radiator and overflow are full-do you have heat? If not, you may have a closed thermostat. If you have antifreeze in your oil, or notice smoke coming out of your tailpipe when the car is fully warmed up, you may have a blown head gasket.

My temperature gauge will go half way then drop

First thing you need to do obviously, is check your coolant level. If coolant level has been checked and all is well, then I'd look at replacing the thermostat.

Coolant temperature relay switch

Most vehicles use a coolant temperature sensor which is located near the thermostat directly connected into the coolant line, or near the thermostat housing, there are relays for the cooling fan which is usually located in the power distribution box under the hood.

Cavalier coolant leaking

Try to remove the thermostat and run it without it. If it does not overheat then you just have a defective one if you have replaced it. Or ou accidentally put it in backwards. It will not hurt anything.
