I have a 2008 Nissan Altima and I took it today to have any oil change. I was told that I have a "bad oil cooler". I am female and I have very little knowledge of a cars structure unfortunately. What kind of price range am I looking at for repair? How difficult is this to fix on your own?

This sounds kind of odd. Most cars don't have an oil cooler. Usually trucks (especially with towing package) have an oil cooler. If the car is an automatic then you have a cooler for the transmission "oil" but it is usually part of the radiator. I would look around on line and first see if you can find a Nissan site that mentions this vehicle having an oil cooler. Unless your car is leaking oil or oil pressure reads way off center (if you have oil gauge in dash) I would be thinking you are not getting a correct answer. If car shows no major issue with oil I wouldn't be spending money on fixing an "oil" issue. Especially if car did not come with a dedicated oil cooler.

I thought that was funny because I never heard of an "oil cooler", but I did a search on, "oil cooler Nissan Altama 2008" and found a link to, "how to replace oil cooler nissan altima 2008" where there were several youtube videos. There were other links as well that told the prices. So do some research and you'll know what you're dealing with. Maybe you could do it yourself. Have a look and see.
