Question about 1997 Buick LeSabre

1 Answer

1997 buick lesabre, temp needle showing 200 degrees and rising, so I pulled off interstate and let cool, then added water to reservoir, then when completely cooled, took off radiator cap and added gallon of water, still looked empty. Then car would turn over, but not start. Held gas pedal down, then started and sputtered and white smoke came out tailpipe. It runs though. What could this be? Why did it get hot? Thanx

1994 Buick Lesabre calls for a 160 or 180 degree thermostat


that is the opening temperature for the thermostat
it opens at 160 degrees which is good for hot weather operation or another with 180 degrees which is good for cold weather operations
The differences is 160 opens sooner to start coolant circulation to keep operating temperature low where the 180 keeps shut and allows the operating temperature to rise up as soon as it open the cold air will quickly cool the coolant.

My 2001 La Sabre coolant fans will not kick on... Recently overheated and checked the relays - what else could it be?


Maybe your thermostat is bad, stuck inclosed....this would boil water before the thermostat and not get to the temp control for the fan, also, ckk bottomhose for collapse.Have you ever changed hoses? Ever put in new thermostat?. They do go bad.

What is the tempeture the slower fan is supposed to turn on at my fans only turn on a 212F and its both


Your question is very confusing. I do not know what you mean by slower fan or the term "it's both" The cooling fan for the radiator only has one speed. It comes on at around 212 degrees which is normal. If you have 2 cooling fans then one will come on anytime the A/C is running. The other one comes on to help keep the engine temperature at around 195 to 200 degrees. The boiling point of coolant in a closed system under pressure is higher than 212 degrees.

I have 1997 Buick LeSabre. I can be driving anywhere at any speed and it will stop for no reason. I have no control over the brakes, steering anything. I spoke to Buick.com and they told me it was not a...


Where did you get your last tank of gas? you may have water in your fuel, a lot of gas stations are adding water to the fuel in order to boost profits. Solution, go to the gas station where you last got gas and fill up a one gallon container. dump that container of gas into a glass jar wait over night and the water will separate from the fuel. for about $3.00 if the water separates from the fuel you know what the problem is. let the car run in the drive way until the needle reads "E" (without running the tank completely empty) then add fresh fuel for a reputable service station.

Porbably is normal temp. Temps are higher, these days, to assist in low emissions. Needs to be 200 to 230 range, usually. The thermostat does not open until just under 200 or so.

New water pump, bypass hoses on a 2002 buick lesabre, but vehicle still runs between 200 and 209 degrees! Is it normal for the temperature to fluxuate in that range or is the thermostat bad??


The thermostat for that vehicle should be a 190 or 195 degree rating. If your temp is moving up and down by only 9 degrees then the thermostat is probably ok. You might check your coolant level and make sure that it is at the proper level and that all of the air has bled out of the system. Do this when the vehicle is cold and never open a coolant system on a vehicle when it is hot.

Have someone pressure test the cooling system - you likely have a head gasket leak

Low coolant light, temp normal


try adding it via the reservoir. make sure you have a 50/50 mix of water and antifreeze. If you want to cheat, cheat on the side of more antifreeze than water. Look for a leak in the hoses and water pump to find out if she has a larger problem that is causing the loss of coolant. look for drips under the car.

Temp sensor switch


They are almost always located on the bottom tank of the engine's radiator. They can have one or two wires (some are grounded to the tank and require only one) and are generally cylindrical with a hex section near the mounting surface to installation and removal.
You will need to catch the coolant when removing it and don't forget, it's a pretty large quantity of liquids.
When I have been in doubt whether one was defective or not, I have attached leads to monitor continuity and heated them in a container on the stove with a candy thermometer in the same water to watch the temperature rise. If OK, they should contact at some value below 212 degrees F.
