  1. Steering wheel offset after turning

    Is there any problem with the alignment? Proper caster, camber, toe-in? Is it the caster that returns the steering to the middle position? Any dry ball joint or tie rod end keeping the unit from wanting to go to the neutral position on its own?
  2. Strange coolant leak

    I'm not sure about the date/time stamp circles on the top of the manifold. On my 1998 they were clear--3 of them. I don't recall seeing a manifold with the tightening torques listed. Remember the EGR valve has 2 rubber o-rings on it. I believe those are both supplied in the pack that came...
  3. Strange coolant leak

    I agree with the ATP plenum. I bought it from a supplier online IIRC. It has the metal sleeve in the vertical tube that takes exhaust gases up and into the incoming air stream. The hot EGR gases through the plastic ABS original styles heats that plastic and it crystallized on my second upper...
  4. How much coolant needed for refill/replace

    Let me ask a couple of questions. When the intake manifold was worked on, was the cooling system refilled with 50/50 or 60/40 mixture of DexCool? Or was it refilled with water or another green coolant not compatible with DexCool? If the system was filled with 50/50 to bring it back up, I'd just...
  5. How to go about Replacing Rear Transmission Motor Mount

    If you have a friend to help while you watch the movement of the engine at the 4 corners while the trans is shifted in different forward backward modes, I'd have to see real movement and then be able to see that mount has softened or torn. I guess I'm say we wasted time and energy doing the rear...
  6. How to go about Replacing Rear Transmission Motor Mount

    Can you see something wrong with any of the mounts? Tears? Rot. Extra movement when the engine is torqued in place with someone watching who knows how much give is right for the 3800 and the model year you have? I had a 2003 with 150K miles and more. The front mount was weakened and torn IIRC...
  7. How to go about Replacing Rear Transmission Motor Mount

    I did the rear mount replacement and it didn't help a thing. I had replaced the front mount. It was a terror to replace with the car on jackstands and my shadetree mechanic neighbor doing the real work. I suspect you'll find replacing the side mounts more helpful if there's something you can...
  8. Air Ride compressor

    Are the fuses labeled on a diagram on the inside of the cover for the fuse box?
  9. Issue with 1999 LeSabre randomly not starting/dying during drive

    The postive battery cables on those have two cables. There is a lead spacer between them. That can corrode. Take the red cables apart by pulling them, if I recall right. The lead spacers could be bought and replaced or cleaned up. Also check the ends of the red cables for corrosion down into the...
  10. Fuel filter location on a 1994 buick lesabre...

    I thought I'd repalced the filter on my 93. It's under the passenger's left foot. Careful with the jackstands for safety or drive wheels on one side up on a tall curb to get room to get under the car... Here's my post from my 1993 leSabre era...
  11. Need help with my Buick LeSabre

    The jerk or hard engagement in shifting between forward gears may be the worn pressure regulator valve that sets code P1811 if I'm remembering. It only happens after the engine and transmission are well warmed up and usually in city traffic speeds where the heating is greater. The pressure...
  12. Driver Unknown / Electrical Issue

    Good point. The radio is the security system and controls lots of things.
  13. 2003 Buick Le Sabre Limited A/C drain hose location

    The rubber drain tube likely is plugged with some gunk or mold crud. You can reach it from under the car but everything needs to be on jackstands, with extra stands for me. I have a ramp of 2x10 or 2x12 pieces that I cut to make into solid ramps. I think they're 5 layers thick. Likely if you...
  14. Coolant smell

    IF your local box stores loan tools, they may have pressure testers for the radiator and cooling system. BUT a cold system may not leak while it does hot. Don't forget your radiator has some age on it now. I had the upper shoulder area on my 1998's develop a crack that opened only under high...
