Dump the DEX-COOL for the Green?

[Legolas894]

Thanks for the replies-Forgot to mention that it's for the 1998 Suburban K1500 with 5.7L V8.

I'm leaning towards switching out since I don't know much about the previous owners maintenance habits. I'm the third owner so who knows if they were good about not letting air in etc.

I did read on here somewhere that the rad cap needs to be changed but is it a different pressure thing or can you just get a rad cap that fits?

It's a pressure thing, at least what I was told, but
as 463 also said, it keeps a shop from screwing up.
