Thanks for your replies, I will do all the suggestions later today (7est) and get back.

I opened the coolant and it seemed fine.

I have the original fan with fan shroud, the one thats always spinning, so it can't not function right.

There isn't much of an opening for air to flow through, could that be the reason when my cars working harder?

Abusing? Thats the funny part I whip it all over the streets, on highway im just driving at 70-80mph @ about 3-4000 rpms and after about 20 miles it starts rising, driving normally.
