I recently developed a coolant leak on my '04 w/ 160K miles. I've already replaced the Degas bottle, oil cooler and installed an EGR delete kit. Until just a few days ago, I could tell I was losing coolant, but have been completely unable to find a leak anywhere. I thought it might be head gaskets, but there is no coolant in the oil and no drip from the exhaust. No oil in coolant either. Three days ago, I noticed a drip from the front end when I first kill the truck. It stops after only a few minutes. I crawled underneath and saw a drop running from the top of the harmonic balancer. If this was my old 7.3 or an old gas burner, I'd automatically assume it was a leaky water pump. I leared a long time ago not to assume anything on a 6.0L and to seek advice before tearing into anything. I can't see any leaky hoses or anything else and I'm starting to get really frustrated.
Any suggestions? PLEASE?
