#3439 of 3508 P0300 Buick Regal 1996
Apr 27, 2009 (10:47 am)
I was driving down the road today on the freeway doing about 80 then all of a sudden my SES light starts flashing and then goes solid.. I guess the flash is to get your attention. So I take it to autozone. She said I had a misfire. First question I changed my plugs about 2 years ago and my wire about a couple of months ago. What would be the most COMMON thing that I should change yet. The light was not the reason I changed my plugs. I was told to switch the little do dad that take hot exhaust from the engine... It build up with carbon... Don't know. Second question. Should Autozone been able to tell me which cylinder misfired? Thank all in advance.

Hi, i was in china for a few weeks and saw the new Buick Regal. I have to say it is a real good looking car. At first, i could not believe it was a Buick. It is prettier than any of the Buick here in the US. Seriously, if this model is in the US, I will definitely consider it.

After all the problems I've had with my 2000 Buick Regal, I should mention that I lucked into the problem: The MAF sensor! After replacing the Crank Shaft sensor and the Low Speed Idle motor/sensor, I got lucky. Fortunately, the Regal started running really badly as the mechanic drove it into his shop. The computer was throwing error codes like crazy, and they all pointed to the MAF. Replacement $250+ solved the problem.
As my mechanic Bob (and I) says: I'd rather be lucky than good any day!

I just checked the picture. Wow. How much is it in chinese yen converted to U.S dollars. That looks awsome. Thanks for sharing.
#3443 of 3508 Engine fan cooling sensor?
Jun 07, 2009 (5:45 pm)
I just got this 1996 regal 6 cylinder. When you idle the fans wont turn on. I bypassed the control switches and can get them to turn on. My question is, is the coolant level sensor the same as the heat sensor that tells the control units to send power to the fans?

I don't know how they wired those. I can suggest buying a Helm factory service manual for the car if you plan to do much work on it yourself. New helminc.com or find one on Ebay--but be careful because if it's a two volume set, people sell one volume and people think they're buying the whole thing. My 98 leSabre is a 3 volume set and 2003 leSabre is a 2 volume.
Notice this says book 1 of 2 and book 2 of 2 in the pictures.
Here's another I found by searching for Lumina rather than Regal. Much cheaper.
Lumina, regal, cutlass, grand prix
Do the fans turn on when the AC runs?
The temperature won't turn them on until 230 degrees or so. I do not know how the sensor is done. I could look in my 98 leSabre book.
On the leSabre one fan runs at one speed and the other has two speeds. If the car heats further or the pressure in the AC goes high then the high speed fan turns on faster. So your really need the wiring diagram for how yours is set up.
#3445 of 3508 2000 Buick Regal intermittently not starting
Sep 14, 2009 (7:54 am)
I have a 2000 Buick Regal that has begun to have intermittent problems starting. All of the instrument panels light up, the radio works, heating/cooling systems are operating, but sometimes when I try to start the car nothing happens. I had a mechanic check the car out and the battery was fine and the terminals were corroded, but he cleaned them and that did not correct the problem. Any ideas, was thinking that it may be the starter, but don't want to spend the money to fix that if it's not really the issue?

Okay I think my head gasket went on my Buick Regal. It is a 96 with 153000 miles. I think it is also hydro locked. The starter will engage but will not spin the fly wheel. My radiator reserve is empty with no clue of the location. Fletchers told me 10hrs Labor 90/hr Seeing the vehicle is worth less then the repair, how involved is it? Is it just a matter of staying organized?Secondly I was told sometime that it will ruin the engine. In that case what am I looking for as far as damage?
Thank you in advance for any help

Is this a 3800 motor? Series II? The plastic upper intake may have leaked through the vertical tube (plastic) that the EGR gases go through to be mixed with the incoming air. The plastic gets crystallized and coolant that goes through upper intake from lower metal intake and then turns horizontal and flows through the throttle body to warm it in winter leaks into the air intake stream and into the cylinders. Was the car missing some before it hydrolocked?
Take out the 6 spark plugs and label them as to which cylinder. If they have a white coating that may be from coolant burning. Then crank motor and watch to see which cylinders have coolant coming out with the upstroke of the piston.
Also under the lower intake manifold there are gaskets that seal around the coolant openings that go into the heads. These may have deteriorated if the original coolant was DexCool (I don't think it was). These can leak and more commonly hydrolock than the leak in the upper at the EGR tube does.
Upper intake manifold by Dorman about $150. Lower intake gaskets between lower and cylinder heads about $50 from GM--use the ones that are metal framed in aluminum, not the originals.
Head gasket failures are really infrequent on 3800s (by GM). If it's the Series II style 3800, most likely you have a leak as described. If coolant ran low and car overheated, then you may have a head that's been damaged from the abuse.
#3448 of 3508 1983 buick regal motor swap
Nov 20, 2009 (6:25 pm)
Hi, I was wondering if anyone could educate me a little. I have a 1983 buick regal limited and was wondering what v8 would bolt in. I loath the sight of a 305 and refuse to even consider putting that sin of a motor in my car. A close relative of mine has a 283 out of a 63 truck that has been rebuilt and is complete and ready to go in. Is this something that I could expect to drop $2,000 on.
