Question about 1998 Buick Regal

1 Answer

The coolant fans on my '99 Buick Regal will only run when the coolant sensor switch is unplugged which then sets off the check engine light. I replaced the sensor yesterday but that hasn't corrected the problem.

You have a short ot ground and it may be in the computer or a relay, if you have an ohm meter I can tell you how to test it. Post here if you have one or can afford to purchase one for $20.00.

2000 buick Regal run hot and hasitate when running. no engene light.


It`s a 2000 buick regal ls. make sure when it gets hot eh fans are running. There is a coolant sensor just below the top radiator hose ON THE ENGINE. This sensor tells the fans when to go on when the engine gets hot and also serves as a low coolant sensor. unplug the sensor and replace it. use a open end or box wrench. if your quick you can replace it and only loose a few ounces of coolant. Hope this helps and God Bless :O)

Location of thermostatic switch 1993 Buick Regal 3.8 motor fan motors don't run


The fans are controlled by the ECM and it uses the ECT sensor for temperature sensing, so if the check engine light isn't on the sensor is not the problem. You need to have an active test run on the fan system to see what code is returned. Have you tried powering up the fans at the relay?

Cooling fans not working on a buick regal 1992?


First check fuse in engine compartment. Use a test light to check for voltage at the fan connector. If no voltage at fan with engine running and hot, replace fan relay in engine compartment relay box. If there is voltage at fan, but fan doesn't run, replace fan. Any questions, please reply.

1990 Regal Coupe 3.1 engine. Low Coolant Light Stays Lit


This is a COMMON Problem that GM had with the Level Sensor Curciut, And they Never Correctly Addressed it. I Have on ocations Replaced the Sensor and that Corrected the Problem, BUT Other times the Light STAYS ON No matter What, I have tracked the Wires and all I Have Ever Found was the Plug Being FAULTY. So if A NEW Coolant LEVEL SENSOR Does NOT Turn off the Light, try Replacing the PLUG Itself.

Buick Regal problem-help!!!!!!!!


Have you done the basic maintenance. Spark plugs, oil change, ect.? As for the fans, if you have a/c one of them should only come on when your a/c is on. The other is regulated by a relay so when your car reaches a certain temp it kicks on.

Low Coolant light flashing on 1996 Buick Regal 3.8


The low coolant sensor should be located in the passenger side radiator tank, You need to take it out and clean the sludge off of it for it to work right. Or you can just unplug it and forget about it, the light will go out and it won't cause any problems.
