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.

SOURCE: my 2000 buick century is over heating fans are

Hi, these are two separate issue here.

The abnormal shift is isolated within three ares. i would suggest checking the transmission fluid level first to make sure of the proper level. if its low, you will experience Miss shifts of this nature. if the fluid level is sufficient, i recommend moving your inspection to the TCM(transmission control module). this is the control module that initiates the correct shifting intervals and it relays the actual shift signal to the shift solenoids located inside the transmission pan. if the module is malfunctioning, it will affect the shift patterns dramatically. If the module is in good condition, i would then move on to the actual shift solenoids themselves.

These devices preform the engaging of the gears within the transmission as stated above. if this device is not working or is malfunctioning, it will affect the way the transmission shifts. If you have not preformed a proper transmission flush and have not changed the filter for a while, it would help if this maintenance was initiated soon if possible.

Now, concerning the overheating issue. if the fans are running in a correct manner, this will most likely point to a faulty water pump or an faulty thermostat that may be froze(stuck in position not allowing proper water flow). the most common fix will be to preform a radiator flush. during this flush, if you notice a rusty water flow and tiny metal fragments running out the radiator, this will confirm extreme radiator damage to the inner coils and it will have to be replaced or rebuilt. I would recommend flushing the radiator and testing both the water pump and thermostat for there operational value.

Please rate and god bless:)

SOURCE: odometer light out on buick century not working

Sadly no, there is no fuse or bulb to replace. You either have to send the instrument cluster out for repair or replace it with a new unit from the dealer. You could also obtain a serviceable one from a salvage yard. Most shops should be able to replace the instrument cluster or advise who can repair it.

SOURCE: 2000 Buick Century gas gauge reads full all the time

You're either looking at a short in the wire that goes to the fuel sender, or a bad fuel sender. If it was just a broken wire, it would read empty instead. The fuel sender is a permanent part of the fuel pump, so that has to be replaced as a unit.

You need t have the computer control module scanned for fault codes, guessing is not a cost effective way to approach the problem. But if I must guess you have a defective transmission if no fault codes are in memory.

After about 20 min. of driving my car starts shifting very hard. why does this happen?

Time for a service. I would also use a transmission treatment in it. To know what was going on in it, It would have to go on a scanner.

Buick Century 2000 gear shifter moves freely will not start

Sounds like your shift cable came unhooked or just plain Broke, it hooks to shifter and hooks to transmission, If it moves freely I would say it's Broken, and that is why car won't start cause it is still in drive

Trans shifts hard somtimes but not all the time not predictable

Have the vehicle scanned. If you have a code for Maximum Adapt/Long shift, replace the EPC pressure control solenoid. This is a real common failure on the 4t65e transmission.

Had the same problem. had the soiniod body changedbeginning of winter. Tranny shift Smoother but problem can back the next spring but less often then before.

Noticed that it was happening on hot day and after driving no more than an hour. Noticed that it was happening also in stop and go traffic.

Sometimes just putting the Tranny at Park and stopping the engine on a RED light fixes the problem.

I haven't gone back to the Tranny Shop.
