Hi, I have a new-to-me 2001 4dr 4wd Blazer. It's pretty nice all over but seeping coolant from the lower engine oil cooler connection. I was advised to get a new radiator so did that. Now it appears that I need some kind of seals for the tranny and engine oil cooler lines. I checked around some on-line, didn't see them. Are these not regular o-rings but some kind of special seal? Where do I get them? Do I need to ask for them by some particular name? Any help appreciated.

 

Any decent auto parts store will be able to help you with these.

 

i can only speak for the oil cooler lines. i just replaced mine on my 95 4.3L, and there are o-rings, but they came with the new lines. nothing special about them, they fit into a grove at the end of the line.
