temp guage

[outlawfish]

I also have a 2010 D8 and the temp guage will not go over 75 degrees. On the trail in it was running 120 -125 road the day and on the way out it would not show over 55 degrees.

Letting idle on the trailer for 2 minutes or longer the guage won't show over 75. My 09 D8 idling the same time show 120-125.

Any ideas? Temp sender or?

Mine does the same, but I have a head mod, no thermostat and a pipe mod.

Is your sled stock?

It has an SLP pipe only
