SOURCE: Where is the radiator cap on 2001 Olds Alero?

if you dont see a radiator cap then the cap for your resevoir tank also serves as your radiator cap, thats where you would put your radiator cleaner and dex-cool in at. it is pressurized just like a normally radiator is with a normal radiator cap on it so dont open it when its hot! the resevoir cap should also have dex-cool stamped on it

There are several problems that could be leading to an engine overheating. I will discuss some of them and you can try to act on which solutions that can help.

THERMOSTAT STUCK SHOT The thermostat, which is usually located in a housing where the upper radiator hose connects to the engine, controls the operating temperature of the engine. It does this by blocking the flow of coolant from the engine to the radiator until the engine reaches a certain temperature (usually 190 to 195 degrees F.). When this temperature is reached, the thermostat opens and allows coolant to circulate from the engine to the radiator.
If the thermostat fails to open, which can happen due to mechanical failure or if a steam pocket forms under the thermostat due to incomplete filling of the cooling system or coolant loss, no coolant will circulate between the engine and radiator, and the engine will quickly overheat.
You can check for this condition by carefully touching the upper radiator hose when the engine is first started and is warming up. If the upper radiator hose does not become hot to the touch within several minutes after starting the engine, it means the thermostat is probably defective and needs to be replaced.
CAUTION: The replacement thermostat should always have the same temperature rating as the original. Do not substitute a colder or hotter thermostat on any vehicle that has computerized engine controls as engine operating temperature affects the operation of the fuel, ignition and emissions control systems.

On rear wheel drive vehicles with belt-driven cooling fan, a "fan clutch" is often used to improve fuel economy. The clutch is a viscous-coupling filled with silicone oil. The clutch allows the fan to slip at high speed, which reduces the parasitic horsepower drag on the engine. If the clutch slips too much, however, the fan may not turn fast enough to keep the engine cool.
The silicone fluid inside the clutch breaks down over time and can leak out due to wear, too. If you see oily streaks radiating outward on the clutch (and/or the fan can be spun by hand with little or no resistance when the engine is off), it means the clutch is bad and needs to be replaced. Any play or wobble in the fan due to wear in the clutch also signals the need for a new clutch.


Leaks in radiator or heater hoses, the water pump, radiator, heater core or engine freeze plugs can allow coolant to escape. No engine can tolerate the loss of coolant for very long, so it usually overheats as soon as a leak develops.
A visual inspection of the cooling system and engine will usually reveal where the coolant is going.
Leaks in hoses can only be fixed by replacing the hose. Leaks in the water pump also require replacing the pump. But leaks in a radiator, heater hose or freeze plug may sometimes respond to a sealer added to the cooling system.

If no leaks are apparent, the radiator cap should be pressure tested to make sure it is holding the specified pressure. If the spring inside the cap is weak (or the cap is the wrong one for the application), the engine will lose coolant out the overflow tube every time it gets hot.

If there are no visible coolant leaks, but the engine is using coolant, there may be a crack in the cylinder head or block, or a leaky head gasket that is allowing coolant to escape into the combustion chamber or crankcase.

In some instances a severe exhaust restriction can produce enough backpressure to cause an engine to overheat. The most likely cause of the blockage would be a plugged catalytic converter or a crushed or damaged pipe. Checking intake vacuum and/or exhaust backpressure can diagnose this kind of problem.

In a high mileage engine, the impeller that pumps the coolant through the engine inside the water pump may be so badly corroded that the blades are loose or eaten away. If such is the case, the pump must be replaced. Most pump failures, however, occur at the pump shaft bearing and seal. After tens of thousands of miles of operation, the bearing and seal wear out. Coolant starts to leak out past the shaft seal, which may cause the engine to overheat due to the loss of coolant. A sealer additive will not stop this kind of leak. Replacing the water pump is the only cure.
CAUTION: A leaky water pump should be replaced without delay, not only to reduce the risk of engine overheating but to prevent catastrophic pump failure. If the shaft breaks on a rear-wheel drive vehicle, the fan may go forward and chew into the radiator ruining the radiator.

On most front-wheel drive cars, the fan that cools the radiator is driven by an electric motor. A temperature switch or coolant sensor on the engine cycles the fan on and off as additional cooling is needed. If the temperature switch or coolant sensor (or the relay that routes power to the fan motor is bad), the fan won't come on when it is needed and the engine will overheat. Likewise, if the fan motor itself is bad, the fan won't work.
The system needs to be diagnosed to determine where the problem is so the correct component can be replaced.

Also check if you are not having a blockage in the coolants hose.

Take care and good luck

Does anybody have a video link on how to flush the cooling system on a GM 3.1L SFI OHV 6cyl motor? I need a vid for this particular motor cause mine is still overheating & i have looked everywhere.

flushing a cooling system is the same method as any other motor

do it without the thermostat fitted
or water pump opening

sacrifice an old radiator hose to adapt a garden hose fitting
for radiator flush

air in system fix
your thermostat housing has no air bleed valve
no top radiator cap

old school way
heater on full
run motor till thermostats fully open
burp radiator hoses
wait till water is running up into over flow bottle without bubble
replace cap
turn off heater
correct level in over flow bottle

why still over heating
you fitted everything i would have ... yet still overheat
leaking inlet manifold gaskets
hose clamps loose
cooling fans spinning too slow
thermostatic fan switch faulty
aluminum radiator is a big one
air ..fins bent or some water channels blocked

or possible head gasket leak

I have a 1998 oldsmobile aurora that is overheating. no leaks, runs fine then temp goes up and coolant boils up to the resevoir cap and comes out around the cap. replaced thermostat. fan comes on

Try changing radiator cap if there is no water in the oil it is not a head gasket could be system just needs a flush. It could also be the water pump is not pumping well try the cap first.

97 aurora overheats new stat flush system oil not milky or over filled new cap still overheat but when i put the cap on half way tighten i dont overheat whats my problem

Was the engine overheating before you replaced the thermostat ?
By not putting the cap on tight, you are not allowing the cooling system to build up pressure. So it could be a restriction somewhere like a radiator hose.

Over heating, thermostat replaced, radiator, engine, and heat core flushed, no water in working, water pump flushes water thru.

You may have air in the system. Let the engine run with the radiator cap off until the thermostat opens. Have someone then get in the truck and bring the rpm up to 1800 to 2000 rpm and hold it there for 15 to 20 seconds while you top off the system with coolant and put the radiator cap tightly back on. Then bring the rpm down to idle and road test the truck. DO NOT BRING THE RPM BACK DOWN TO IDLE UNTIL THE RADIATOR CAP HAS BEEN INSTALLED COMPLETELY. I suggest replacing the radiator cap at this time also.

Po410 secondary air injection system malfunction also po442 evamporatiave emission control system leak detected (small leak) 2001 Olds Aurora 135,000 miles runs great though

Two of the more common problems with Auroras.
P0442 - There is a small solenoid (about $30.00) mounted near the L.R. wheel that will fix this.
P0410 - Usually due to leaking Air Injection Valves. These are about 2" square, one near the passenger side firewall, the other near the drivers side radiator. They cost about $200.00/ea. most people just leave it go as it does not effect performance.

Changing antifreeze in a 2001 GMC sonoma

you can remove the lower radiator hose on the bottom of the radiator. **remember to let the vehicle cool before working on**, as coolant burns are very serious and difficult to remove quickly with water. make sure that you collect the old coolant, it will need to be disposed of properly [not into the ground] and take a water hose and place it inside the top of the radiator to flush the system . once the system appears to run clean of all coolant , replace the lower hose and refill as desired. once full, crank the vehicle with the radiator cap off and continue to fill. this will allow the water to flow and release any air pockets that may be in the system. once full and constant flow is assumed, replace the radiator cap .

1998 aurora overheating

I had the same problem and tried several things that didn't help. A friend introduced me to a Northstar mech. that explained the real problem. Internal engine relief was faling which created overheating between cylinder sleeves and engine block creating blow back pressure in cooling system. There is a fix for this. The mechanic helped me with the problem and car is running once more... Anyone thinking they have a head gasket, intake gasket, or thermostate problem should look at this fix.

On a 2005 Equinox where is the coolant cap? Not that antifreeze holding chamber, but the cap where you are not suppose to open when its hot cause it shoots out everywhere. I want to put all new antifr

Not all vehicles have the cap you are talking about. If your vehicle does have a radiator cap, it will be somewhere along the top of the radiator. Would recommend going to a shop where they have the proper tool(s) to do a coolant flush.

1997 olds. auora overheating

feel of the top hose, if it's soft when the car is running and at operating temperature then it's probably air in the system, not allowing the pump to pick up the antifreeze. To get the air out let the car cool completely (like overnight) then fill the reservoir, leave the cap off and run the car until it comes up to normal operating temp. (watch to see you keep enough antifreeze so the tank doesn't go empty.
My 97 Aurora did the same thing and this fixed it.
