chevy silverado duramax transmission cooler hoses on eBay.ca (item 180599590768 end time 21-Dec-10 10:59:12 EST)

your going to have to pull the amp meter out and test for any unwanted battery drain with the truck off.

do you have any aftermarket electronics installed?

Just do what BWR said or take your lines of and go to a hose shop on get some real ends and hose made up.. They will never stop leaking especially if your in a colder climate..As for the Batt ya must have a drain on it some where, I know mine won't handle much as well but its only sometimes. I think if something is left on plugged in it must activate the BCM or something cuz mine has did this as well..the only thing i had plugged in was a phone plug. I know with my PPE sometimes I could never load a tune it would lock up, had to unplug several times and reastart the truck ans so on. Was told by PPE that if the BCM stays powered up that that would cause issues with the programming.. Dunno

Thanks for your help
