Thanks for the replies.
Yes, the upper most EGR coolant line was just loose enough to cause it to leak once it was warmed up enough. I would have taken it back to the Dodge dealer that replaced the EGR valve for the Ford dealer, but they are 200 miles away and I wasn't sure if I could even make it that far with the leak. Amazing how much coolant can be lost through such a small leak, about a gallon of G-05 & water pre-mixed in 500 miles. I was refilling the reservoir almost daily. I shudder to think what could have happened if it weren't for the low coolant alarm in the reservoir! My irritation with the Dodge mechanic was somewhat compensated for by the discovery of a really cool looking (8mm?) Snap-On metric socket w/ a ball style u-joint attached to it. Finders Keepers
The Dodge mechanic also used standard worm drive hose clamps instead of the constant tension clamps. Is this a no-no? Although the coolant hoses appear to be factory, with the worm drive clamps it looks like the hoses are almost too big for the EGR fittings, or maybe the hose ends have swelled from age, exposure to coolant, etc. I'm thinking about replacing the hoses and clamps. Is it possible (or advisable) to use standard heater hose and worm drive clamps instead of the molded factory hoses and tension clamps?
On the oil drain plug, it is the original allen head plug, oh crap. Anybody know the size of the pipe thread for the drain hole? Does the Fumoto drain valve require the sump pan to be re-tapped?
Is a ProGuard oil filter the factory oil filter? To me it looks rather small for an engine that size. I used the 'heavy duty' oil filter on our VW Passat TDI, and it was about 3 times the size of the Jeep filter. Maybe size DOESN'T matter?
