Can I remove/replace the water inlet pipe without removing the water pump on a 3.0?

Asked by Sep 16, 2016 at 09:58 AM about the 2000 Plymouth Voyager Minivan

Question type: Maintenance & Repair

2000 plymouth voyager/3.0

Have a small coolant leak coming from near the thermostat.  Changed the
thermostat, it's not that.  From what I've read, it's possibly either the o-ring
where the inlet pipe connects to the water pump, or the inlet pipe itself has
become breached.

The repair manual I have does not cover replacement of the inlet pipe
anywhere, but apparently they ARE replaceable.  The book does cover
water pump/timing belt replacement though.

My question is, what do I need to pull to replace that water inlet pipe?

That's a great design, isn't it? If it's the pipe, you'd probably have to pull the intake plenum to replace it. You could probably get to the small bypass o-ring or hose, but the inlet pipe itself.... yeesh. Considering you have to pull the timing chain to remove the water pump, and that inlet pipe o-ring is on the backside of the water pump, it might be easier to pull the intake.
