Question about 1994 Buick Century

2 Answers

My car's temp gauge sits in the middle when sitting idle, but whenever I drive my Buick Century 93 or 94, after 10 minutes or so, Temp needle is close to Red (Hot), but continues to sit at the last white line before Red. Whenever I stop, Temp needle returns to middle. I took my car to a shop, where he found everything to be normal, Antifreeze is good, and coolant is good, on my car's computer, cooling system kicks on at 255' degrees.

    does the cooling fan work?

  • morris64423 Oct 08, 2010

    Yes, the fan kicks on, and keeps it from reaching Red unless I'm going about 70 mph, then the needle is barely in the red, and my dash briefly shows the Temp warning light, but usually I drive 65 and under, and it never reaches Red.



    I can hear the fan kick on, Temp gauge needle just stays on the last White mark before Red while Driving, and settles in the Middle while idle.

Indicates blocked radiator cores or thermostat only partially open-- insufficient coolant flow at high rpm and the air flow is not cooling the water quick enough
if it has never had a radiator change take it to a radiator shop and have it flow tested
check the radiator core fins as they corrode off from salt on the roads and will not transfer the heat if missing

SOURCE: low coolant light

In the surge tank, there is a sensor that detects the level of the coolant. It's most likely the sensor is stuck on the low position. All this sensor does is slide up and down as the coolant level goes up and down. You can tap the side of the surge tank near where the sensor plugs in and see if it will dislodge. You'll see the 2 wire plug at the bottom of the tank towards the front.

SOURCE: 93 buick century -turn signals

The Buick Century uses separate relays for the hazard warning and turn signal functions. The turn signal relay is located on the accelerator pedal bracket, and the 4-way flasher relay is located on the convenience center near the left kick panel. Try switching these two relays with one another to see if your turn signals work instead of your 4-ways.

SOURCE: how to replace a coolant level sensor, 2000 buick century

The coolant level sensor is located on the radiator. If you are looking at the engine from the front of the car it will be on the left side. There will some kind of clip holding it in the radiator. Removed the clip and pull the sensor out. You will lose coolant so try to swap it out quick or drain some of the coolant out. Once new sensor is installed, install clip to keep the sensor in place and reconnect the wires to the sensor. Crank the engine and make sure the coolant level is full. This should correct your problem.

No heat coming from the vents.


If it is a manual system--sounds like coolant low ie: air bubble in system. If it is ATC system, Check Codes, if no failure codes, coolant may be low--air bubble in system--most Durango's have air bleeders in system.

Car temp gauge/heat


TDIs can take a while to heat up in cold weather. Sometime 10 minutes or more.

If it is taking longer than 10 mins for your temp gauge to hit 190, you may need a new temp sensor, which is pretty cheap and just pops into the engine block, almost right next to the battery.
