Coolant spraying... What is going on?

[Waterloo]

Yep, heater core... All makes sense now. Thanks Rawze, I will pull a vacuum on the system, I have the tools... And I have not driven the truck yet, she is not leaving the driveway until this is fixed. I tell ya, it does not take much to upset these trucks.

And you are correct, not all of the coolant went back in. Dumb ass mistake on my part, I should have figured this out by myself. But, that is how we learn and the reason for this site. ;-)
