SOURCE: 1993 buick lesabre

I'm trying to fix another problem on my lesabre and I saw your question here. I don't know when or if you even will need or read my answer, but I've changed the water pump before on my '93. It's not as impossible as you might think. I'm NOT that mechanically inclined. I'd be happy to describe it in detail if you are interested. Feel free to write me at tnslipp@comcast.net, and I'll see if I can help.

SOURCE: coolant leak at intake 1994 Buick LeSabre 3.8 ltr

There are several areas of possible leakage. One is the hose and plastic outlet from the intake manifold on the passenger side of the engine. The hose runs low, underneath the alternator. The plastic outlet cracks, the hose gets old, the clamps on the hose can also be loose. The replacement outlet from the dealer is steel, not plastic.
Another possibility for leakage is on the driver's side of the intake manifold. Underneath the air inlet is a metal cover on the end of the intake manifold. This covers the coolant passages at the end of the intake. Mine was oozing antifreeze..you don't have to pull the intake to replace this.
The other place for leaks is the intake itself..requiring removal of the intake. I've done this...I don't think it is that bad of a job. However, if you put in a new intake, don't forget to put in a pcv valve..it fits under a small cover at the right rear of the intake manifold.

SOURCE: 1993 buick lesabre won't start. security light is

The coded key probably needs to relearn. Turn ignition to crank and release. Let sit in on position (engine off of coarse) for a full 10 min. turn off for 30 sec. and repeat 3 times engine should start. This procedure should take 30 min. so a booster is needed to maintain a full 12 volts. Do not attempt w/out a charger connected;

Where does a thermostat goon a 97 Buick LeSabre.


Should be under the thermostat housing where the radiator hose connects under the throttle body. This is on the driver's side of the engine near the exhaust cross-over pipe.

Clean throttle body air


The accelerator cables? Spray them up good on the outside with a penetrant spray, like WD-40.
The problem with sticking throttle body parts (like the butterfly valve, and the idle control valve) is not carbon deposits, it is coking deposits. This is from air impurities. Remember that a hose from the PCV system is routed back into the air intake-this carries a lot of impurities. Over time, coking deposits will build up. Air passages controlled by the idle control valve will get these coking deposits. I'm not sure how much the internal carbon cleaning helped the throttle body.
I believe I would get a second opinion- I have never heard of an idle valve that can't be taken off and cleaned.

Can you tell me where the throttle position sensor is located on a 1990 Buick Lesabre?


look to see where the accelerator cable is and directly opposite thru the throttle body is the location. This is near where the air filter attatches to the motor

93 lesabre - starts right up but cuts off when you take your foot off the accelerator.


check your map sensor as well as the range on your tps/ throttle postion sensor and your throttle body gaskets sometimes that engine will get a air leak that corrupts the vacumn necessary to operate the fuel rail which in turn will shut the fuel off at a idle

I have a 1997 buick lesabre w/ 24k


While there is a problem with the plastic Intake manifold, I would not worry too much about it. I was a buick tech, I own an 01, and at 95K I replaced my intake gaskets, but only because I still had an extended warranty. My manifold was fine.

The gaskets had begun to leak just a little, and I probably could have just used a good sealer, but since I had the warranty and managed a repair shop, I had it done. You will know when it is time, You will either smell the coolant, or your coolant light will come on. Just because it is a common problem, does not mean it will be your problem.

Coolant disappears with no visable leaks.


This is what they are talking about, a major problem for GM. Google it and you will see how big the problem is. Don't drive the car until you fix this.

The 3.8-liter V6 may leak coolant into the engine from the intake manifold. A new gasket kit, revised throttle body nuts, and sealing compound is available.

Coolant leak


This engine has a plastic intake, jsut inside of the throttle body is a tube that comes from the EGR. It will burn through the plastic into a coolant passage located inside of the intake. You will need to replace the intake manifold and if you want there is a revised lower intake manifold with a slightly smaller diameter tube to prevent future burn through that will prevent a reoccurance. However, it is a costly repair for what is a infrequent failure. I suggest just replacing the upper intake manifold. They are now available through the aftermarket.
