I have a 2000 Blazer 4x4 that has a bit of an oil leak from the oil pan gasket needing to be replaced. I have cleaned up the area around the pan in hopes that I will be able to see where the leak is coming from without all the dirt and grime under there. I'm pretty confident that the leak is not coming from the oil cooler line, but I was curious if there is any benefit to just replacing the oil cooler lines as preventative maintenance.

Thanks!

 

If you have stock oil cooler lines then yes it would be wise to replace.
The factory lines do not last. Build a set of your own so you never have to worry about them again.

These are mine I did 10 years ago and still no leaks.
