Does it come up to 180 pretty fast or does it take forever? I got a check engine light and code for engine not up to temp, put new thermostats in and was amazed how much faster it warmed up. If you haven't done thermostats, it wouldn't hurt to do them. They are kind of a pain to get at but not at all impossible. There are 2 different ones, make sure they go in the right spots.
