I have done a search here and not found exactly what is happening to me, so thought I would post up the question. My 6.4 has developed a small coolant leak that appears to be on the bottom, back drivers side corner of the radiator, where the metal joins the carbon/plastic part of the radiator. The leak is approx. 50 - 60 drops per minute when the truck is hot and NOT running, The leak seems to stop once the truck cools to below 120 or so. There is no leak at all when the truck is cool and no apparent leak when the truck is running no matter the temperature. The only place there is a leak is where described and it is dripping straight off that corner of the radiator and onto the ground just under the front bumper. I read on here one other person having a similar problem and it was fixed following a flush. That makes no sense to me but
. Would hate to spend the time and money on a flush with no resolution or a increased leak rate. I installed the venturi mod about a week ago and it did not help, I also have a coolant filter to install but don't want to do until I get this problem fixed. I would appreciate any help at all with this problem. Don't have time to put it in the shop right now and really don't want to spend all that it will cost for such a small leak. Also forgot to mention that I have just been adding distilled water, could that be thinning out the mix and causing it to leak?
Thanks again for the help.
