temp. gauge barely moves
On my 96 century, the temperature gauge hardly moves when the engine is running and I know the coolant is hot. How can I troubleshoot this? Is it the dash gauge or the sending unit? I hope it's not the dash gauge. I can't imagine myself taking that dash apart.
If it is the sending unit, is it easy to take out? Thanks, Ed

Believe they had a few engine options till we got shafted in 97 to a single option. Remember reading somewhere they had a few different style sensors for temp. Newer one made the gauges less aggressive to the actual temps preventing people from freaking out about 220*F coolant temps. Should be on the t stat housing just under the throttle if it's the "Muscular 3100" power plant. You able to read temps of the coolant to verify the T stat isn't stuck open? Was your MPG different from normal.

Hi guys,
speaking of engine temps, have you had a chance to check out the problems Buicks were having withe Dexcool in the cooling system ? Should be able to find the info in google re; intake plenum problems with Buicks using Dexcool coolant.

Vid for the T Stat on 3100-3400

I took a pic of the book if it's that same for your engine this is the location below the throttle body. You still have to drain the coolant to remove that cause coolant will drain it's self if you pull it out as is.

On another site, a guy suggested running a wire from the green slot on the connector plug to a ground on the engine. With ignition key in the ON position, but engine off, the gauge should go all the way up. Which means the wiring and gauge are O.K. Ed
