I've owned both the Buick Century(1994 wagon with the 3.1 engine) and currently a 1999 Regal LS (with the 3.8 engine)
The Century was quick off the line, but solely lacked the muscle when it came to highway merging and passing. Anything over 45mph was a chore. The Regal 's 3.8 200 hp engine is much stronger...has all the power I would ever need. That said, it has recently developed a possible slow coolant leak in the lower intake gasket.
#3191 of 3508 Speaking of Coolant Leak
Apr 23, 2006 (10:18 am)
In doing a "search" in this discussion I've noticed many Regal owners to have had problems with coolant leak and problems with lower and upper intake gaskets.
One post mentions that there was a recall for all 2000-2003 Regals with the 3800 Series 2 engine. Under the recall GM would replace the engine throttle body fastners with redesigned fastners and add cooling system sealant to the radiator.
A few questions please: Anyone have this done and what was their experience? My 1999 Buick Regal has the same engine as those under recall...any idea why it may not have been included?
Would having new throttle body fastners and adding cooling system sealant be an option for me?(see my above posts on coolant leak) Sounds a lot cheaper than the $1,200 for lower intake and water pump my dealer recently quoted me.

The different bolts connecting the throttle body to the UIM were to change how the force was applied and I believe to spread it out more evenly. The sealant was in the motor on you 99 Regal when it left the factory.
GM had gone away from putting sealant in the motor from the factory because it tended to leave a crud in the overflow tank after a while or early on. People didn't like seeing that in the clear tank so they left it out. But most motors have it in and it seals miniscule leaks from the factory assembly.
I added the sealant, two tablets, to my 03 leSabre each time I've changed the dexcool to refresh that sealing material which plugs cracks that _might_ occur. I do the the same for my 98 leSabre.
If you didn't put a couple of tablets back in you 99 when you changed the antifreeze every two years (I hope you've done that) you should add it now. Buy the packet from your local Buick dealer, take two of the tablets and crush them with a spoon, then add them directly to the warm radiator and take her out of a good run. I drove to Cincinnati one time I did it. I open my hot radiator when it's not over heated but I don't recommend that for others. Do not add the tables to the overflow reservoir; they go directly into the radiator so they can circulate through the motor before they settle out to the bottom.

This is true, the 3.1 does lack a lot of midrange and upper range torque but it can spin the tires from a start. My friend has a Grand Prix with the 3.8 and i like it a lot better than my Regal's 3.1. Thats not saying i dislike the 3.1 engine, it has been reliable and i am closing in on 200K miles. As for gasket leaks, I have heard a lot about it but i haven't seen it yet. I have heard the older engines didn't have this problem until the mid 90s. Apparently, the Dex-cool wasn't designed to run up to 100K miles as advertised.

I have a regal GS. I average 21 mpg. I don't always run 93 octane. When it is colder out I'll run 89. Usually 91 is fine. I don't get on the gas too much.
Go Regal LS, if you don't need supercharger. Reliability has been pretty good. I've owned for 5 years now.

Did you notice a strange smell outside of the car, from possibly the coolant burning off ???
Has anybody noticed this?

I've never noticed the smell of coolant in the 2 years I've owned my Regal.
A recent two hour interstate trip yielded no signs of coolant leakage.
#3197 of 3508 Noise/2000 BuickLSE
May 04, 2006 (7:03 am)
I have a weird noise coming from the front end of my car also, it's not a rattle noise, it sounds like a the fan belt is worn, but it's not. I've taken the car to 3 auto shops but no one can tell me what the noise is. I was told to change the belt to a gator back belt; I got new belt but not the gator back belt. I was told to change the water pump, I changed that, I was to it was the pulley, I changed that, I was told to flush the engine and add heavy oil, I did that, I have spent about $650.00 and still can't get rid of that annoying noise. Someone, Please help me...: confuse:

Thanks for that tip on the sealant tablets. I had asked Buick in Detroit about that, and they said, yes , a good idea to add them since they were part of the recall. I have had no problems with my 00 Regal, and will change fluid now at 75,000 mi.
#3199 of 3508 Whars my PCV Valve?
May 08, 2006 (12:37 pm)
I just bought a 95 Buick Regal with the 3.8L non-turbocharged engine. I've looked and looked and can't find the PCV valve. Auto Zone looked it up on their 'puter and gave me a verbal description - it plugs into the intake manifold somewhere on the top passenger (serpentine belt) side of the engine. Still can't find it. Does anyone know where I can find a FREE repair manual with drawing showing me exactly where it is online? Can someone give me a better verbal description? Do I have to take something apart to get at it?
