Where can i get a 180 t-stat, are they easy to install? What are the benefits of a new t-stat. Feedback please.

Check your local parts stores for one. It will lower operating temps, which will increase the life of your engine, as well as give you better milage, and even a few HP.

is it easy to put in/ install?

Uhh, very... very easy. your upper radiator hose connects to the coolant neck / thermostat housing, two bolts hold the thermostat housing to the intake manifold, remove it then take the thermostat out get a new thermostat, o-ring and gasket, scrape the old gasket off and put the new one on I always use some RTV also.

Buy Chilton'* #28200 at the same time, along with the fiber gasket and rubber seal for the thermostat/housing. You need the book anyway. With it, the first time you do this should take less than an hour. 20 minutes for each change after that. Put a rag down in the lower intake while you CAREFULLY scrape the old gasket off.

Also, make sure the engine is REAL cold or your wearing coolant.

where can i get the chiltons manual? NAPA?

I dunno if Napa sells Chiltons? They'll order it in a couple days if they don't. Ask Kennginn. He'* a Napa Manager
