I have a 1997 1/2 model S90 which is a 960 bastard with a new name. It is still rear wheel drive. I want to change the thermostat because it takes the car about 10 miles to warm up. Please tell me the specific one I need and if there is some special thing I need to know. THANKS

 

This is what you need: http://www.fcpgroton.com/SV90/volvos90v90heating.htm

You may be able to get it at a local store.

You must replace the O ring which is supplied with this one.
