I assume that it is similar to a '93. It'* easy to replace, and as Kennginn said...make sure you get all the old gasket and sealer off both surfaces. When you get the parts, make sure that they also give you the rubber seal (like a flast o-ring). They often forget that when you get the parts. So you should have a 195 t-stat (standard), a flat gasket, and a rubber seal. I just answered in another post the part numbers...but, this is what I bought yesterday, part numbers and what I paid
T-stat Borg/Warner 13849 - $4.59; Gasket Felpro - 35534 - $1.52; Seal Felpro 35486 - $1.74.
