I put a used low mileage motor in my 1990 bonnie SSE. All went well except I need to replace the two throttle body coolant tubes. I can't seem to find them at my neighborhood parts store. Can anybody give me some direction?

There are two lines from the throttle body, both are 3/8 with 90 degree bends. One of the lines has a two hole flange. I'm hoping somebody knows what the actual names for those parts are and where I can get them.

90 degree hose barbs (cut down if needed) and any 3/8" rubber hose? I think those are dealer-only hoses. You might be able to find a 3/8" 90 degree silicone hose as well that should work.

HPS make some, HPS is overpriced usually:

Those would be the closest thing to an OEM part that I could think of.

These lines are actually metal, not rubber. One of them has a two hole flange. Does that make a difference?

I guess I'd need to see a picture, I'm not sure which ones you're talking about.

Here is a link to the gallery with pics of the throttle body lines. They have gray calk on them but the pics show the location on the Throttle body.

Looking like a junkyard only part, can't even find it in my CSM.

That sucks, but I guess that's my next step. Thanks for checking it out for me. Junkyards here I come. This is the best site ever, I would be still stuck on step one in bringing this great old car back to life.

I looked through all the salvage yards, but all the throttle bodies were on shelves with no lines. Until I found two yards out in the boonies with enough acreage to just stockpile the cars until the parts are called for. One salvage yard was no-go but the other had a 1990 Buick LeSabre, bada-bing, bada-boom, I had the tubes but I had to buy the whole throttle body (Not a problem). The bottom line is the type of salvage yard makes a difference when looking for the little stuff. Thanks Mattstrike for the push in the right direction, I'd still be banging my head against the wall without it.

Glad to see it worked out!

Can you post a good picture of it? I am still trying to figure out what you were on about.

If I can remember to, I have one on the '89 that isn't covered in goo that I can take a picture of tomorrow.

That's one of the tubes, the other one is right behind the first one. If anyone is trying to salvage those tubes, be careful when removing them. One of the tube ends snapped cleanly off when the salvage yard removed them and I didn't even notice it until I got it home. The tube looked intact until I compared it to the old one. Luckily I only needed the other one which was still in good shape.
