this thread is how to replace the thermostats on a 3.0 L Optimax, a 2.5 L could/would be different.

Not that difficult on the 2.5. I use a stubby 8mm wrench and can remove/install without messing with the fuel rails.

Shouldn't have to remove the fuel rails, but I had to loosen mine and back them off about 1/4". It's not a hard job.
