Hello All: Has any one charged the AC for 1996 Buick regal? I know where the charging ports are. They are right below water resorvayor. But do not know which port it is. Is it the one with thick tube or the one with the thin tube? Which one is charging port? What should be the pressure? Any help will be greatly appreciated. Thanks.

Replying to: paresh1 (Jul 22, 2008 6:19 pm) I am trying to figure out the same thing..I went and bought a 20 dollar manual and it just told me that only a service professional should do anything with the A/C!! I have done it on my other vehicles without an issue because usually they put a blue or different colored cap on the correct port. If you can shed any light on this I would greatly appreciate it. If not I will keep looking until I figure it out. Thanks Barn

Replying to: usmc0352 (Aug 05, 2008 2:48 pm) The charge port is located under the Air Filter Box. There are two port. The correct port is located on the thick tube connecting to cylinder. The thick tube comes from compressor to clynder and from clynder to evaporator in the dash board. Let me know if you have any further question. |

I have a '91 buick regal, 3.1 engine. It recently overheated while driving on the highway in very hot weather. The reserve tank to the radiator was full of water, so we are not sure why it overheated. I am wondering if anyone can tell me what I may be able to do to fix the engine. We have a broken valve, piston, and head. I have read that it really entails a lot to be able to do this ourselves. Anyone know more or less what the price range would be to fix this? Someone has suggested to us that it would be better to just get a new engine for the car. Opinions?? Any help is greatly appreciated. Below are pics of the piston and the head.

Replying to: regrim (Dec 15, 2008 7:19 am) Does your radiator stay full-not the reservoir-the radiator? If so, when you're done refilling and purging air from the heater, see if there's air in the thermostat housing and the radiator is full. Probably the heater can be purged of air by revving the motor after the car has run long enough on a short drive for the lower radiator hose to be hot. Do both heater hoses stay the same temperature indicating enough flow? The only thing I've heard that might apply is that when you think everything is full, have someone hold the motor at 1500 or so and you'll see the radiator level go down. Refill the radiator while they hold the motor at that speed. Put the radiator cap back on while they're still holding the speed. I've heard a talk show tell people to do that. |

I noticed about 2 months ago my regal is not getting very good gas mileage. My car has 86,000 miles and the average mpg was 23.5 mpg and quickly dropped to 19 mpg. The low traction light was on and the brake light was also on. I took the car to a local mechanic and they added brake fluid which took care of the lights. Then they hooked it up to a computer and found that the car had been misfiring so they changed the spark plugs and wires. They thought maybe the brakes were hung up and when they checked them they had to replace the pads and rotors. I brought my car home and I've had 3 tanks of gas through it and the average is now 16.9 mpg. Does anyone have an idea what the problem could be? I was hoping to take the car back to the same mechanic but he hasn't returned my call. Taking that as a bad sign I made an appointment with another mechanic on Tuesday. What do you think the problem could be?  P.S. I'd also add that twice the review mirror lights stopped working and started working again hours later.I haven't noticed this problem in a week. Not sure that it's at all related.

Replying to: notamechanic2 (Dec 28, 2008 1:50 pm) I think engine 3800 V6 has issues. The head Gasket may have damaged and coolent may have leaked into teh Engine and May be damaging the Head assembly or something. This engine has history of coolent getting into the engine and damaging teh engine and mechanic do not know what the hell is going on. Let me know what you find out. |

Replying to: regrim (Dec 15, 2008 7:19 am) The mechenic are idiots and do not know what the hell is going on. Then I changed the Coolent sensor. Located on the right side of teh radiator and that fixed the problem. For some reaon it was not circulating teh coolent. Does teh "Low Coolent" come on? This Model 3800 has design issue on coolent system. It also damages the engine head Gasket and other plastic Parts due to the over heating of the engine. |

Hi, my Buick Regal runs really cold. I've put three different thermostats in it finally leaving a 195 in it. When the car is at idle the heat from the vents gets a little warmer, once you start to drive it gets cooler. The running temperature of the car is only 50F at best. Can any give me an idea as to what this may be. Any help would be appreshiated.
