pusher engine water heater not work?

[joeastro]

HI. replaced 39 foot water lines from winnie 36 journey DL..from rear engine to front. changed out the leaky hot air water exchange. BUT NO HOT AIR. vacuum valve on dash board replaced. BUT STILL NOT HOTAIR.. a/c works fine. but no hot air or defrost.



any one replace vacuum dash board switches?
could be they plugged in the vacuum lines wrong?
hot water 4 port vacuum valve moves, but dont know if hot engine water coolent
is really flowing into heat exchanger up front.. hose do not get hot when touched
and after running engine on road...


anyone know if there is an engine PUMP on the catapillar pusher engine that is used
to pump coolent to the front of the winne?


thanks

There are usually some valves underneath that shut the water off to the front. Did you check them? Also disconnect the return line and run vehicle possibly a air lock in the system.

oky will see if i can find where the rubber lines start

on the engine in the rear and see if something like a hand
valve is there..


could it be another vacuum valve?


the A/C has a vacuum valve i believe back by the engine but the A/C works fine.


just the hot water does not see to get upfront.


thanks joe

Just fyi, here are the rear heater shutoff valves on my 2005 Vectra (both shown in the OFF position) under/beside the engine, driver's side:
