Go with the 87c thermostat. This way the engine will run at the proper temperature for the ECU Temp Sensor to send the best signal for proper fuel mileage and power. The 80c is fine, I ran one for 5 years on my 84 (with the 2.1 engine), but I found that after changing back to an 87c a few years ago, my mileage got slightly better and the tailpipe was a lot cleaner (relatively speaking) in the long run. Heater felt more efficient in keeping me warm too. The 80c is probably best for areas that experience high ambient temps most the year around. And yes, do change the thermostat - you should whenever changing out the water pump, it's just plain common sense. -- Jim Thompson 84 Westfalia 2.1 "Ole Putt" 73 K Ghia Coupe "Denise" 72 411 Station Wagon "Pug" oldvolkshome@gmail.com http://www.oldvolkshome.com ********************************** On 12/15/06, Kevin Jessee <kjessee@katewwdb.com> wrote: > > I recently found that my 91 was running like a pos.
