    Hello all-

    I just hooked up my MM1 to my 99 dodge ram truck today for the first time. All seemed well until I started driving down the road. My truck started overheating almost immediately. The last truck I used this plow on was a 02 F250 with a diesel, it never overheated. I looked over my coolant and made sure the thermosat was open, and the water pump was a flowing. I played with the height of the plow on the truck and as long as I didnt go over 40 MPH it stayed around 210 degrees. When I came to stop lights the truck temperature decreased a bit. Is this common?

    Did you angle the blade for better airflow? Try posting in the Dodge section- they may have more answers for you.

    Yep- angled it, dropped it real close to the ground, lifted it way up. My best results were close to the ground. Thanks for the tip on the dodge discussion forum. I have posted it there as well.

    Not sure if those trucks have an option for a heavy duty fan-clutch but you may want to look into it.. Diesel's run cooler first off.. Goodluck!
