Engine Temp.
I have a 2004 F250 6.0L all stock with about 47,000 miles. I live in upstate new york where the temp. has been between 20-40*F. Lately when i drive my truck the temp takes a very long time to come up. I start the truck and let it warm-up for 5 to 10 min. and then drive, today i drove about twenty miles about 30-50 MPH and the truck did not get up to normal running temp according to the factory guage. Lately when the truck dose warm up it seems that the needle on the factor temp. guage sits a hair higher than it normaly dose. Do not have a aftermarket guage yet to tell exact temps. Wondering if anyone has had a problem with the thermostat sticking. Thinking that is my problem. The truck has to go in for a cold start issue next week. Is the thermostat or cooling system part of the 5 year/100,000mi warranty.

I've got an 03 that I've had for about three weeks now. I'm in WV and we've shared the same weather patterns.
When I go out each morning, I'm walking my two dogs at the same time. I'll start the truck and let it idle while the dogs do their thing. It runs about 3 - 5 minutes before I jump in and head to the office. I notice that it takes the truck about 3 to 5 minutes of actual driving befire I feel the heat start to kick in.
I've considered putting a cover on the grille to limit the cold air hitting the radiators but just haven't had the time to find a nice looking cover yet.
If you are letting it warm for 5 to 10 and then driving that far and not getting heat sounds unusual. I'd say it's time to have the dealer address the issue.
Good Luck!

I let mine high idle for 20-25 minutes. It's been in the mid to upper 20's here and it just gets to 160-170 by the time I get 3-4 miles. It takes these things A LONG time to heat up. They have a great cooling system, it just works too well in the winter.
Yes, an aftermarket temp gauge wil tell you the exact temperature. The stock gauge is kinda like an idiot light. My stock gauges goes up to normal when the engine hits around 135-140. I've never gotten above 190 to see where the temp gauge starts going into the hot side, but I an say that between 135 and 190, it never moves.

Tonight very cold about 5*F. I started my truck 04 F250 6.0L and then started my 2004 F450 6.0L dumptruck. after letting both trucks idle for about 15-20 min while loading some equipment in the garage i noticed the F450's temp was 1/2 to 3/4 the way up to normal running temp, and my F250 was all the way down on the C. Dose anyone know if their is more than one thermostat in the 6.0L and how hard it is to change.

You guys that idle your trucks are doing them a real disservice. This is not 1970's diesel technology. The faster these thigns warm up (without being abused) the better. The longer you let them idle, the longer they run cold. So do yourselves and your trucks a favor and stop idling them for extended periods. There is a reason every tech manual in print tells you not to let them sit around idling. You injectors, turbo, valves, rings will all be happier when opperating at proper temperature.
