Hose has become brittle from age Hose clamp has cut into hose
The radiator is at the front of the engine compartment . It connects to the engine with ( 2 ) large rubber hoses , 1 at the top of the radiator and 1 at the bottom of the radiator at the opposite end
On the 2.4L z24 I think you are talking about the one on top on the driver sid. That is the OUTLET GASKET and it is a rubber O RING.The temp. sensor is screwed into that to detect cooling temp. as it leaves the engine. Coolant leaves the engine to head to the radiator to be cooled.
It depends on your engine, but the easiest method is open your hood. Look down at the engine and look to the right of the radiator.. look for a large black rubber hose. It connects to where the thermostat will be.
Follow the rubber hose coming out of the top of the radiator. Where it connects to the engine, you will find a metal cover and the thermostat is under that cover.
look on top of the motor follow the radiator hose the one on top all the way from the radiator to the engine.. under that elbow that connects the rubber hose to the engine. take off the bolts around it remove it if you buy a new stat before your will know what it looks like.
The radiator is located at the front of the engine compartment . It is connected to the engine by two larger diameter rubber radiator ( " rad " ) hoses.
a prior response has explained your ? located in fitting where lower radiator hose connects to bottom of engine. engine water temp should be cooled before draining. to access need to drop plastic shroud under front of engine/radiator, then drain radiator into container, facilitate by opening vent on left side of radiator (has Philips screw cross), and remove radiator cap. from under car remove 2 bolts that hold fitting at end of lower radiator hose where connects to engine (caution - still some juice here). bend out of way to access the thermostat that will be pressed/wedged in seat with rubber o-ring (still more juice here).
Radiator hoses are made of rubber and over time these units fail due to the environment. When they fail the rubber can get dry rotted which will cause the lines to flatten and crack.

It's near the front of the engine compartment and has ( 2 ) rubber hoses connecting it to the engine ( at the top and the bottom of the radiator on opposite ends )
There is a rubber elbow on both ends of the metal pipe that connects to your PCV valve.
