I'm about to replace the lower intake gasket on my 97 LeSabre Custom. It is leaking coolant on the passenger side, where the thick silicon gasket meets the block. Do I have to remove the upper from the lower? Is there a step by step guide anywhere? Can I get some guidance here?

If it has the 3.8l, 3800 engine the upper has to come off.

From what your saying, it'* not your gaskets are leaking. It'* the coolant elbow. You can change just that by pulling the alternator bracket. The elbows are like $5 or so at auto parts stores. Take about an hour.

it is a 3.8 series II, it could be the elbow. Is that the formal name for the part? do I need any "O" rings or sealant for it?

I took the alternator mount off and when I removed the elbow from the intake, it was broken off where the O-ring should be. I stuck my finger in the hole and came out with a wrinkled O ring. I guess the end piece is inside the engine. Do you think it will hurt anything?? I really appreciate your advice. I already had the lower gasket set and went to get a 10mm 1/4" dr swivel to start removing the intake. what do you think about the broken off end of the elbow??

Dan, You are a lifesaver. I really appreciate your knowledge and experience!!!!!

The elbow was broken off at the O ring in the intake. I stuck my finger in the hole and came out with a wrinkled O ring but no end. Do you think it will hurt anything that the end piece is still in the engine??

I had the same thing happen to me awhile ago. Considering its plastic, I really don't see it being an issue should it get dislodged and float around a bit. But, you really should try to get it out prior to installing the new one.

I made a hook on a piece of coathanger and got the broken end out. I think I am good to go. no apparent leak as of this evening.

Hard to beat a $5 fix.
