Based on the description, either the problem is on the water pump, the radiator fan or the hoses. If you have replaced the hoses or noticed that the hoses are not brittle and clamps are ok, then you can eliminate it as one of the source of the problem. Inspect the radiator fan if it turns on when you remove the thermostat. The thermostat looks like a small plug that has wires coming out of it and is connected to one of the radiator hoses. If it does not turn on it could be a problem on the relay or the fan itself. You may swap the AC fan relay with the radiator fan. If it still does not turn on then it is a bad fan. If it turns on then, have the relay replaced. Other than that your water pump for the radiator needs replacing. It may not be circulating water correctly.

HOW TO CHANGE A THERMOSTAT ON A 97 AURORA


It's at the engine end of the lower radiator hose. Remove the hose clamp and two bolts holding the hose fitting. It will fall into your hand.

Follow the upper radiator hose to the engine, where it hooks up, that's the thermostat housing, will be on the housing or just a few inch down from there, will have a two wire connector.

How to change the thermostat


For 1999 Oldsmobile Aurora 4.0L SFI DOHC 8cyl check thie how to replace a Thermostat:

Parts:
1. Thermostat

Tools:
1. 3/8 in. Drive Ratchet
2. Needle Nose Pliers
3. Screwdriver
4. Cooling System Pressure Tester
5. Socket Set
6. Radiator Hook Tool

Steps:
Step 1 Open the hood and locate the vehicle’s radiator.
o Tip: Make sure the vehicle has cooled down before inspection.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.


Step 2 Remove the vehicle’s radiator cap and use a radiator pressure tester to check for leaks.

Step 3 Drain out some of the engine coolant in the radiator so the coolant level is below the thermostat housing to prevent leaking when replacing the thermostat.

Step 4 If necessary, remove the upper radiator hose.
o Tip: A twisting motion may help to initially break the upper radiator hose loose. You can also use a flathead screwdriver to help pry the hose off. Make sure not to damage the hose.

Step 5 Remove the thermostat housing bolts.

Step 6 Remove the thermostat housing.

Step 7 Remove the thermostat.
o Tip: Make sure to note the way the thermostat is installed. Installing the thermostat backwards will affect how the cooling system performs.

Step 8 Clean the mounting surfaces. Install the new thermostat as it was removed and always use a new thermostat gasket.

Step 9 Reinstall thermostat housing and tighten mounting bolts evenly. If applicable, reconnect the upper radiator hose.

Step 10 Refill the cooling system with coolant.

Step 11 Start the vehicle with the radiator cap off and allow the engine to run for several minutes. This allows the air bubbles to escape the cooling system.

Step 12 Reinstall the radiator cap.

Step 13 Run the engine until up to normal operating temperature. Remember to keep an eye on the temperature gauge to prevent overheating.


Hope helps (remember rated)

Leaking antifreeze


Check your hoses entering your block and radiator. you may need to bring your vehicle into a garage and ask for a "Pressure Test" this will indicate if you have a crack or leak.
Good Luck.

2001 aurora engine heats up when not moving down


Likely the fan(s) not turning on when engine gets hot. Is the check engine light on? Read the code(s) and repair as needed. Check (when cold) the fan(s) for free turning--if seem bound or hard to turn, replace the ailing fan. Check the radiator and reservoir fluid level. Watch the fans as the engine heats up. Feel the radiator area where the upper engine hose connects. It will suddenly turn hot when the thermostat opens. The fan assembly should activate somewhat after. Hopefully, the engine code recognized a defective temp sensor and was replaced.

1998 aurora


I have had this problem with my 98 aurora and have replaced all the same components. Temp gauge routinely shows 200 on highway (Fine) but in the city in stop and go will get to around 245. I installed a switch to manually turn on the cooling fans by connecting the ground to pin 86 in the relay for the fan(s). Otherwise the fans will not turn on to 245. This fix works but would like to know an actual solution.
