Need help with slow leaking coolant transfer tube

[inkpot]

Cannot see how an unpressurized system would cause a water pump to fail??

Agree. WP bearing/seal are cooled by coolant so very low coolant levels might cause WP failure.

Hey all. Exact same issue with my bypass outlet leaking as well. The pipe itself is in excellent condition, but the o-rings were badly gunked up.
That pipe is a massive bear to pull!
Maybe there is some trick I'm missing, but two female ends, 90 degrees from each, on a short, bitty pipe with no give... means not happy times in trying to get that thing on and off!

Thought I might bump the question; anyone have any advice on how to get that pipe on/off? As mentioned, its a stubby little thing, with two, 90 degree ends.
How do you get the thing on/off without a mallet?
