engine block heater ?
I have a '94 7.3 diesel and have been plugging the heater in at night. The last few days I've noticed a little antifreeze on the driveway and wondered if the block heater could boil the antifreeze over. I've recently had the antifreeze changed and is protected to well below zero

I have a 99 and have to plug it in if temp is under 40. No anti-freeze but sometimes see a very minor oil leak increased a touch when plugged in. I am assuming this is because the oil is kept warm and allows is to "flow through/around" the seals and gaskets better than when it is cold. I would say the anti-freeze is not boiling over given the normal operating temp is higher than then block heater output. It is possible that you have a small leak that occurs at a warm temp that you do not see when the vehicle is still and cool.
As a side note, I plugged my truck in last night expecting a bit of a winter storm. When I unplugged it this morning I got the electrical ride of a life for 4-5 seconds. Apparently while plugging my truck up in the cold and dark, with thick gloves on, one of the prongs slipped outside of the plug. So this morning, with no gloves on, I grabbed the bare metal prong and was notified immediately that I was wrong. The temps were well down in the teens and the truck would not even think about starting. So I plugged it in the way it is supposed to be and waited about three hours for it to warm. The moral of this story: even simple things need attention to detail.

Thanks...I'll check all hoses and radiator... The heater seems to be working because it starts much better when plugged in. I plan on buying a timer so I don't have to keep it plugged in all night.
thanks again
