2002 Taurus Duratec DOHC; 84,000 miles-Late last summer I took on servicing the cooling system; hoses, TSTAT, flush,etc. I had to work in stages, as this car can be quite difficult to service. After the second phase, one of those plastic elbow fittings busted, so that too had to be replaced. Afterwards, Just under the water pump, a minor leak persisted and I finally got around to it this week-Water Pump, a hose, clamps, etc.Since this leak has persisted since late summer, I expected to find clear evidence of EXACTLY where the leak was, I anticipated either the pump seal or the plastic fitting cracked. NADA. Post work pressure test and drive all seems good now, but I'm wondering if other members have had a similar experience.
