Diesel Engine Coolant
Anyone ever have coolant turn to pudding? Unfortunately I have. Wonder what would cause that to occur and how do I get it out of the engine.

Thanks for all the replies. Engine is a 400 Cummins ISL. I do recall topping off the coolant some months ago so that might be the source of the problem. Now what?
After you flush it using the advice form the other posters, I recommend refilling with Zerex ED-1 extended-life diesel coolant. It does not react adversely with regular green coolant, so if there's any contaminant left, it won't continue to make more "pudding" (I call it tapioca... in small amount thats what it looks like when you drain the coolant).
