Ebay water pump does $1000 in damage.

I've had 6 Dakota's and 2 Durangos, only the most recent Durango has a ".7" engine (4.7) and I haven't had that one very long.

plus a "1500" with a magnum and wouldn't say cooling system was an issue on any of them. My biggest issue with radiators seems to be caused by Bambi.
I'm replacing the 2nd radiator in the 1st Durango, the first one was Bambi's fault, 10 years and 100k+ miles later I'm replacing the radiator again because I believe the trans cooler may be plugged up so I took advantage of O'Reilly's lifetime warranty after 2 trannies in 3 months.
Even though I ran 5 cans of "Kooler kleen" thru the radiator when I replaced the first trans. I'm about to put that 2nd trans back in, so it'll have a fresh radiator and aux cooler with the overhauled trans.
