2000 Buick Lesabre making Knocking noise

Unread post by Buick_Gal » Tue Dec 14, 2010 5:16 pm

I have a 2000 Buick Lesabre, On cold days it makes a knocking noise that quiets after driving about 30 miles. It is not a ticking noise like an exhaust leak. The knocking sound gets louder as i accelerate, but I can still hear it when i start it. I have tried putting an additive in my fuel, thinking maybe it's bad gasoline, but I drive 70 miles a day and it has been going on for about 3 weeks now. On warm days, there is no noise. I've been checking the oil levels daily, and it is always fine. Is this noise normal??

Could it be that your oil is too thick- and till it warms up it's not lubricating your engine- it has been cold in most parts lately

Can you explain popping out?
Does it keep giving the wrong reading on the gauge?
Is it setting a code?
What engine size is in your Buick.

Buick Lesabre belt pulleys question

Unread post by Buickman » Tue Jul 16, 2013 3:13 pm

I have a '95 Le Sabre and it has the idler and tension pulleys that are flat and smooth not grooved. Will any grooved pulleys interchange with these and still use the serpentine belt? I have an oil leak I can't fix and it causes the belt to come of these flat pulleys. If I can change them out I will be in good shape.

No, you must use the correct pulleys. Step one, get the oil leak fixed.
