When I did my t-stat install I lost quite a bit of fluid...even when pulling the hose off and lifting it up high I still dropped out a jug of coolant and almost a whole gallon of distilled water! Just be prepared to replace that amount...I had those on hand so it wasn't too bad- but it was a mess! be careful tightning those bolts back as well...its all aluminum and can easily strip out as you tighten her back up...by the way, I went with a 180 t-stat and dropped almost 25 degrees off my normal driving temps!

According to E-T, if you have everything set and ready and are quick and the engine cool, you can do it with minimum coolant loss. I lost about a 1/2 gal or more when I did it, oh well..
