Second the last comment - I had to change a stuck stat, and getting it out of the engine was a right PITA.
So, I decided to bite the bullet and goe for a remote. By the time I priced up a remote stat against buying the bits for a PRRT, there was very little difference and yet the PRRT offered a number of additonal safety advantages.
Incidentally, anyone got any pics of their PRRT installation - not sure I've put mine in the best place?
