2003 Lb7

[Baggtie]

Hey I have a 2003 LB7 dirty turd I replaced the back plate not there's three things that connect to the back plate the oil cooler and that block of plate are two but there's a tube up top that I need to figure out what it's called and where it goes because I have a darn massive coolant leak there

Welcome to the forums.

I am guessing you are asking about a 2003 LB7 Duramax. If that is the case, you might have better luck posting on a GMC/Chevy/Duramax forum than on a tractor forum, dealing mainly in older tractors..
