Diagram of which hose to disconnect to flush radiator

both top and bottom hoses of the radiator are disconnected to flush out the radiator. I would suggest that you have this done professionally by a radiator shop as doing it yourself is not really effective as the flow rate has to be checked to monitor flow improvement to check for blocked cores. Blocked cores will not flush clean.

Hello. Here a non-photo diagram. Hope this helps!!!

The thermostat is located on the side of the water pump, the water pump is located just above the a/c compressor, the thermostat is fed coolant from the radiators lower radiator hose.
Thermostat :
1. drain coolant and tighten drain plug ( easier method : remove radiator cap, get big drain pan, place drain pan under lower radiator hose to radiator connection, remove clamp, slowly remove hose, allow coolant to drain into pan, now is a good time to remove radiator hose and clamp from thermostat housing )
2. remove thermostat cover / cap ( easiest to get at this when front of car is supported by jack stands and right hand side lower cover is removed ).
3. thermostat cap is held on by 3 bolts / remove thermostat.

You will notice that the thermostat's air bleed hole is pointing up and lines up with notch in water pump housing,,

ATTENTION :failure to install new thermostat in the correct location will cause engine to overheat.

1. install new thermostat to water pump, make sure air bleed hole lines up with notch, install and tighten bolts, install a new lower radiator hose, fill cooling system.

thermostat # 17670-77E00
lower radiator hose #17854-65G20
hose clamp #09401-36403
upper radiator hose # 17852-65G20

Many auto parts stores carry maintenance and service manuals for the 1987 Ford vehicles. Don't recall seeing a "diagram" of a "cooling system" though. There isn't much to it...a radiator, outlet hose to engine block, inlet hose from engine block to radiator with a thermostat installed. Problems...thermostat can stick, radiator can corrode up, leak in radiator can occur, engine water jacket can rust up. Routine maintenance and antifreeze solution can help keep the radiator working fine.

Need diagram of engine for 2002 cavalier z24

Its the upper radiator hose should be located topside beside the engine oil dipstick,any smaller hoses you have running into the radiator are heater hoses, the lower radiator hose is where coolant enters from radiator into engine and is pumped up with water pump thru water jackets in engine and eventually returns thru the upper radiator hose which is most prone to damage due to splitting and cracking, I hope this helped.
