I'm stumped on heater coolant routing to water pump. Removing the retaining pulley you need to remove coolant lines that go to engine block and water pump. The one to engine block was easy to access by removing bolt holding tube bracket into block. The line to water pump I can not see anything that'* holding it in but it will not pull out.

Anyone here know the trick here?

Can you post a picture of what you are talking about?

Here'* the only picture of the pump I have. Are you trying to remove the pump? There'* a long bolt that you access trough a hole in the body side rail.

No, I've removed the water pump. I'm after the retaining pulley which requires the heater hose lines removed at the engine block and water pump housing. The heater hose come out of firewall into aluminum tubes that attach to the block and water pump housing. I will post a picture tomorrow

on my Toronado my heater pipes were rusted and very hard to get out. I just had to wiggle and pull, etc.
I'm late for work. will follow up tonight unless someone else answers.

you're on the right track. there'* nothing else holding it in. except you might want to undo that wiring harness clip that'* attached to the pipe. I'll bet it'* just rusted and stuck. try some PB Blaster or other lube to loosen it up.
good luck. let us know how it goes.
