1987 B700 Bus loosing power when hot
Have a 1987 B700 Bus with a 6.6 Ford/New Holland diesel using a Bosch P pump. We are in the process of converting it into an RV but something odd happened over the weekend, where engine pulls power and I am able to get up to 55+ mph when cold. Once thermostats crack open and engine is up to operating temp, I start to loose power and speed drops dramatically. No buzzer for coolant level is on and no warning lights come on. Not to say the warning lights are burnt, any ideas???!!
