"List" opinion:� DO NOT loop the lines if deleting rear heater.� Plug 
them.� Otherwise hot coolant quickly returns to engine instead of going 
forward to radiator for cooling.� But...until I learned that from 
List...I had it looped for about 15 years.� No ill effects.� Just turned 210,000 miles on a 1.9, runs like new, no leaks, not one drip.� 
Plugging is easier anyway.� 

PS� I used the Rear Heater "loop" to
 instead go through a 15 foot section of 1/4" copper tubing, formed 
around a circular form (spray paint can) and dunk that into 5 gallon tub
 of water; added a quarter turn ball valve from local hardware store to 
let flow in or stop.� Ball valve has equivalent effect to "plugging".� 
Heats up 5 gallons of water from "ambient" to 120 degrees F in about 
15-20 minutes of driving.� I rigged a Walmart BBQ meat thermometer 
(probe inserted into tub of water) to display that up by dashboard, 
wiring underneath van of course.� Have used EVERY camp trip for about 8 
years now....works primo.� HOT showers are a MUST for me when camping!� If you can, why not?

True, but they are $100 and I don't use it enough in winter to justify this
with all the other stuff I have to do. So, it's either plug or loop the
lines.� I think they should be looped, any opinions?

For some reason the rear heater cores are generally available in the normal
automotive aftermarket. Compared to heater cores for some other cars the
price of these is not all that bad. Considering the damage that can be done
if one suddenly fails I would suggest replacing it. Why install another 25
year old wear part?
