Seems to be the time to be changing thermostats, I'm hoping to do mine this weekend as well.
Was actually going to take the alternator off to give me better access, probably think I'm mad but I've removed the alternator before and its as easy as anything
Did mine today, found that using a 1/4" wrench and extension instead of a 3/8" made getting the bottom bolt of the thermostat housing back on that bit easier.
