96 power stroke coolant leak
I have a 96 power stroke with a small coolant leak. Have replaced water pump and oil cooler gaskets and O rings; Twice. looks like its leaking on the back side of the front header of the oil coolers. front cover gasket? I pulled the fan belt so I could move the a/c and power steering pump to get a better view while its running and still can not see leak even with a dental mirror as there are two steel lines running vertically. removed the bolt holding the steel lines to gain a little better view. without the water pump turning its more of a weep. top view a little weeping on back side of front oil cooler header/front cover area. bottom view can see weeping coming down the backside of cooler header. Just can not see complete back side of header from top or bottom view. Puzzled!
