thinking the same thing and have always thought that but when I was looking under Gunghoe's serv. man. for his 91TT, I was actually looking for oil cooler info as my previous posts show and it shows the stock thermostat at 170F!!!??? I don't get it either. Even Zedparts.com show's 170F for the stock thermostat.
