Over heating on highway

    I have a 1987 Ford F-150 with a plow. The problem is when I go about 5 miles at highway speeds it starts to over heat. I've tried to angle the plow different ways and different heights. I've put in a 180 thermostat in. And I have even tightened the clutch on the fan tighter. I need to find a way to run down the highway. I have seen some air deflectors but no link where I can get one. Anybody have ideas on how to get it to run cooler with the plow? And yes it runs just fine without the plow on.
  2. Overheats With Plow On

    I had a 91 Bronco that was undriveable over 30 MPH with the plow on. The only way I was able to drive it was with the plow 2" off of the ground. All mid 80's to mid 90's F series trucks had that problem.

    Well just remove clutch on fan and just mount fan to pulley so no more clutch then fan will stay all time spin.

    What I heard that truck with snowplow must not use on highway because that heat and too danger to drive with weight on front. They want driver go at 40 mph that it.

    Ok, remove the clutch it is. That was what I was thinking. Now I just need to find a spacer kit to do it. Thanks for the input.

    Replace the fan clutch and fan blade if it's rusted bad. Make sure you get the correct direction of rotation fan blade. Having the fan engaged all the time will eat into your gas mileage. I did mine on my 89 and it made a world of difference. Make sure all your fins on the radiator, trans cooler and A/C condenser are open and not bent or blocked. Overheating, is this a new issue or old? Drive with the plow low and rt angled is what the Meyer install guide says.
