Diesel Gods,<br> Is it difficult to change the thermostat on the 2002? It takes a while for my engine to warm up. I noticed several guys have had the same issue. Some guys have talked about the leg of the thermostat breaking. Thanks. 8)

I am not for sure on the 2002. My 99 was simple. I had to add a little coolant, but it was easy. Make sure you get a cummins part. Auto Zone seems to have problems with the replacement parts.

REMOVE THE THREE BOLTS. HAS A 0-RING FOR A SEAL.<br>I LOST VERY LITTLE COOLANT ON MY 99. DEALER LOW<br>PRICE WAS AROUND $15.00. MAY BE HIGHER WHERE YOU GO

Sounds normal Dan. I'm 2 miles from the interstate, and it takes me 5 miles at 65 once I get on for the needle to reach full operating temps. I recently took the back roads to get to work, and at it took forever at 0[sup]o[/sup] to get up to temp at slower speeds and rpm.

I wouldn't touch the thermostat, instead buy some engine covers to block some of the cold air entering the engine compartment!

Ditto the broken leg. One for my 99 was $17.88 at Cummins. #3944194 180 deg. Seal was not a true O-Ring but rather a molded seal that surrounds the outer edge of the stat.
