Are there any other 3800 series cars that share the same cooler lines as a 91 sse.

According to Rockauto.com
Bonneville-1991-1993
Olds Delta 88- 1991
Olds 98 1991-1993
Olds 88 1992-1993
...it goes on with a couple buicks and cadillacs with about the same year range.

Do you have a line leaking?

I would assume olds 88 and buick lesabres would be similar..Let me do some research on this

Asome thanks, and ya mine have a slight leak so wanting to change them but geezz they are hard to find.

Off to the j-yard this weekend.

Let us know what ya find bud!

The oil cooler adapter and coolant lines differ from the early series (pre '91) H body to the later one so make sure which ones you have.

Here are some pics of the two adapters:








If anyone needs part numbers for the lines I have them
