Fixed my Dodge Cummins diesel block
on February 11, 2012
I found out I was loosing coolant as I had the dreaded "53" Cummins engine block in my 2001 Ram. I tried this because the options are few - replacement short block is $5000 or a $1000 drill and mash in block filler metal. To my very happy surprise the Bar's Leaks 1109 worked great and all I had to do was pour it in the rad leaving the antifreeze in there. Just make sure you remove enough coolant from the radiator to fit the whole bottle in the rad. DO NOT put any in the oveflow bottle as it will plug the siphon tube and you'll have to clean the canister out.
