Regarding 3.9 V6. Okay.....changing my water pump, and due to the ecessive corrosion, I'm replacing alot of the cooling system parts. When replacing the bypass hose, there are two fittings that the hose clamps down to.....one on the water pump, and one on the intake manifold. The water pump came with a new one.....while I'm at it, I want to replace the corroded one on the intake. Any tips on how to get this off? I've been trying PB Blaster with vise grips, but it's a tight squeeze and hasn't budged yet. Is there a special tool to remove these?

Thanks!

 

pb blaster is the best. if it wont come of then you will need to take intake and remove it that way.

 

I let it soak for a night, and gonna give it one more try. Thanks!
