Cooling System
Ensure that the engine is completely cool prior to starting this service.
1. Remove the recovery tank or radiator cap.
2. Raise and support the vehicle.
3. Place a drain pan of sufficient capacity under the radiator and open the petcock (drain) on the radiator.
è Plastic petcocks easily bind. Before opening a plastic radiator petcock, spray it with some penetrating lubricant.
4. Drain the cooling system completely.
5. Close the petcock.
6. Remove the drain pan.
7. Lower the vehicle.
8. Determine the capacity of the cooling system, then property refill the system with a 50/50 mixture of fresh coolant and distilled water.
9. Leave the recovery tank or radiator cap off to aid in bleeding the system.
10. Start the engine and allow it to idle until the thermostat opens (the upper radiator hose will become hot). The coolant level should go down, this is normal as the system bleeds the air pockets out of the system.
11. Refill the system with coolant to the proper level.
12. Turn the engine OFF and check for leaks.

Engine Diagrams


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

How to change the radiator


TO CHANGE RADIATOR FIRST YOU TURN OFF RADIO FIRST TO KEEP FROM LOSING RADIO CODE.DISCONNECT NEGATIVE BATTERY CABLE.RAISE FRONT OF VECHICLE SUPPORT ON JACK STANDS.REMOVE THE LOWER SPLASH SHIELDS.NOW YOU NEED TO DRAIN THE COOLING SYSTEM.CATCH COOLANT IN A LARGE DRAIN PAN.REUSE COOLANT IF ITS FAIRLY NEW.IF COOLANT VERY OLD CHANGE IT.PUT OLD COOLANT IN SOME EMPTY CONTAINER TAKE TO A GARAGE OR WHOEVER DISPOSE IT.DONT POUR ON GROUND.HARMFUL TO THE ENVIRONMENT.MOVE THE AIR INTAKE DUCT PASSES OVER THE TOP RADIATOR HOSE.NOW WHEN ALL COOLANT DRAIN OUT.LOOSEN UPPER AND LOWER RADIATOR HOSE CLAMPS.THEN DETACH THE RADIATOR HOSES FROM THE FITTINGS.IF THEY ARE STUCK GRASP EACH HOSE NEAR THE END WITH A PAIR OF ADJUSTABLE PLIERS AND TWIST IT TO BREAK THE SEAL THEN PULL IT OFF REMOVE SMALL COOLANT SURGE LINES FROM TOP OF RADIATOR THAT GOES TO THE OVER FLOW RESERVOIR..DISCONNECT COOLING FAN ELECTRICAL CONNECTOR.THEN REMOVE THE COOLING FAN.REMOVE DISCONNECT AUTOMATIC TRANSMISSION COOLER LINES GET READY TO CATCH TRANSMISSION FLUID THEN PLUG LINES. NOW UNSCREW THE FOUR BOLTS TWO ON EACH SIDE OF THE RADIATOR THAT ATTACH RADIATOR TO THE AIR CONDITIONER CONDENSOR CAREFULLY TIP TOP OF THE RADIATOR SLIGHTLY TOWARDS THE ENGINE.REMOVE THE UPPER RADIATOR SEAL AND LIFT RADIATOR FROM THE ENGINE.NOW IS THE TIME TO REPLACE THE UPPER AND LOWER RADIATOR HOSES WITH NEW ONES SINCE ALL COOLANT REMOVE I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.NOW WHEN YOU GET READY TO INSTALL NEW RADIATOR USE SHEETS OF CARD BOARD PROTECT RADIATOR FINS AND CORES FROM DAMAGE WHILE SITTING RADIATOR BACK IN PLACE.ONCE YOU GET UPPER AND LOWER HOSES IN PLACE ALSO PLACE SMALL SURGE HOSES FROM THE OVER FLOW RESERVOIR TO RADIATOR NEW THERMOSTAT AND TRANSMISSION COOLER LINES ALL HOOK UP. START POURING ANTIFREEZE IN THE RADIATOR OR OVERFLOW RESERVOIR IF RADIATOR DONT HAVE RADIATOR CAP ON IT.POUR A FULL GALLON ANTIFREEZE AND A HALF MORE IF LONG AS THE COOLANT STAYS ON THE COLD LEVEL MARK ON OVERFLOW RESERVOIR DONT OVER FILL.IF YOU POUR ANTIFREEZE IN RADIATOR KEEP POURING ANTIFREEZE UNTIL LEVEL STOP DROPPING AND LEVEL OFF AT RADIATOR TOP.START ENGINE CHECK FOR LEAKS. LET ENGINE RUN UNTIL IT WARM UP TOP RADIATOR HOSE GET HOT.WATCH COOLANT LEVEL IN RADIATOR OR COOLANT OVERFLOW RESERVOIR WHEN THERMOSTAT OPENS COOLANT LEVEL WILL DROP.ONCE YOU HAVE ENOUGH COOLANT IN THE SYSTEM COOLANT LEVEL WILL STOP DROPPING.THEN YOU READY TO GO.LET ENGINE SIT A LITTLE WHILE CHECK COOLANT LEVEL AGAIN.COOLANT LEVEL IN THE OVER FLOW RESERVOIR SHOULD BE AT HOT MARK FOR HOT ENGINE AND WHEN ENGINE COLD COOLANT LEVEL SHOULD BE AT THE COLD MARK.IF POUR ANTIFREEZE IN THE RADIATOR COOLANT LEVEL SHOULD BE AT TOP OF RADIATOR BELOW PRESSURE CAP.

BUY YOUR RADIATOR HOSES FIRST MAKE SURE NEW HOSES MATCH THE OLD HOSES. BUY NEW RADIATOR CLAMPS AND HAVE EXTRA GALLON OF ANTIFREEZE. MAKE SURE ENGINE IS COOL IF YOU GOING TO CHANGE TOP RADIATOR HOSE REMOVE RADIATOR CAP OR OVER FLOW JUG CAP IF YOUR RADIATOR DONT HAVE RADIATOR CAP FIND RADIATOR DRAIN PLUG.PLACE A CATCH PAN.OPEN RADIATOR DRAIN PLUG CATCH ANTIFREEZE. DRAIN HALF ANTIFEEZE IF YOU GOING TO REPLACE TOP HOSE AND DRAIN OUT ALL ANTIFREEZE IF YOU GOING TO CHANGE LOWER COOLANT HOSE TO WATER PUMP.WHEN DONE CLOSE DRAIN PLUG.PUT ANTIFREEZE IN A SAFE PLACE FROM PETS AND KIDS UNTIL JOB DONE. WHEN YOU REMOVE COOLANT REMOVE WATER HOSE CLAMPS THEN REMOVE RADIATOR HOSES PUT NEW RADIATOR HOSES AND CLAMPS ON HOSES TIGHTEN HOSE CLAMPS DONT OVER TIGHTEN. POUR ANTIFREEZE IN RADIATOR.CRANK ENGINE UP CHECK FOR LEAKS.CHECK COOLANT LEVEL WHEN THERMOSTAT OPENS ADD MORE COOLANT AS NEEDED.

Radiator system is spraying steam out once it heats up I dont know anything about the coolant system and dont know if its the radiator or the hoses or if it could be anything else.


Hi
Firstly check from where the steam is coming out from.
Is it from the top radiator cap???... then its loose just tighten it...
Is it from the hose.... lower hose or upper hose.... change it.
worst case if it is from the radiator itself.....
Whatever you do... please dont go for a long drive till this is fixed....
Till you get it fixed please top the radiator with clean water else the engine will cease...

2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat


Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

Car is still heating up after flushing the radiator, checking all hoses and changing the radiator cap, havent changed the thermostat but the symptoms dont seem like it would be the thermostat unless it is...


One good way to tell if the thermostat is the issue is to carefully touch the lower radiator hose when the engine over heats. If the lower hose is cool there is no circulation through the radiator and the thermostat is the problem.
Unless there there is an obstruction in the hose blocking coolant flow.
Has the lower radiator hose been changed recently? Make sure there is a spring in the hose to prevent it from collapsing and restricting coolant flow.

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.
