Question about 1998 Oldsmobile Aurora

1 Answer

Overheats while Idling.

Car runs fine when going 35-40 mph or more but if stopped at stoplight or idling it overheats. I have checked fan relays, fuses, and my coolant. They are all ok. My fans did not kick on when temp reached 220 while idling.

There are 3 cooling fan reays in a 98 aurora and they are computer controlled. the low speed fan relay should turn on when the ecu detects a temp of 229 degrees and should turn off when the temp has dropped to 216 degrees. it is best to check the temp with a computer monitor so you can see what the computer is reading. If you turn the a/c on you can see if the fans are operating. If they don't come on with the a/c you may have a problem with the high side a/c switch. A bad thermostat can cause the fans to come on late.

You may have a bad relay. Have you tested it to see if it is working or have you changed it out with a new one?

Does the hose on the fill tank need a clamp or not? why does vechile overheat if the fill tank on the side is full?


A clamp might not be needed, this is not under pressure. It would not hurt to have one, but a simple spring clamp is adequate.
A vehicle can overheat for many reasons. When does it overheat most? During periods of slow speed, stop-and-go, and idling? Or during long high-speed drives on the highway?

If it is mostly idle and slow speed, check your cooling fan. Mostly they are thermostatically controlled, only turning on when needed. If this does not work, check the fan relay, fan motor, and fan thermostat.

If it overheats mostly at high speed, it is most likely that the radiator is partially plugged and needs to be backflushed, rodded, or replaced.

If it always overheats quickly after startup (less than fifteen minutes) it may be that your thermostat is not opening properly.

Overheats when idling. relay was replace and still overheats. fan runs when the a/c is on


When the engine heats up the fan should come on at this time. It is must be the relay or switch. There should be different relays for the AC fav and the cooling fan, even if its the same fan. If you have to you can wire it up directly, so when the ignition is turned on the fan will always run.

My scerity sys went off and I my car over heats I think it needs a new thermastat


maybe your security system monitors engine temp ... it doesnt have to be the thermastat thats bad .. it could be the radiator fan switch or relay bad .. you can tell which by the following.
1. if it overheats only when idling or in heavy traffic but does not overheat while on the road (moving) then your problem is more likely the radiator fan switch, relay or fan motor ..
2. if your car overheats all the time even while driving then it could be the thermostat ..

check belts, coolent level and radiator clogging ..

Engine overheats when idling. Top of radiator exploded! Now I must replace radiator. Did bad thermostat cause this, or was the culprit a bad radiator fan relay?


It could be either.Replace the thermostat anyway for good measure (it's cheap).And have the fan and relay tested.I't a very easy quick test that any honest,capable machanic can do

When idling saturn ls 4dr sedan wants to overheat


Sounds like either you are low on coolant or the cooling fan isn't working. With engine cool remove radiator cap and check coolant level, top off if necessary. If full start engine and turn on A/C full blast, full cold the cooling fan should come on almost instantly, unless there are two individual cooling fans in which case only one may turn on. If no fans turn on check all fuses whether related to fan or not. If all fuses fine try swapping relays around, they are usually all the same size/style. If fan still doen't work you have either an open positve or ground side of the circuit, Which will require wiring schematics and a multimeter. If coolant full and fan/s turn on and engine still overheats you'll need a new thermostat installed.
