Possibly to make it easier to successfully bleed the cooling system?
In any case, coolant bleeding / trapped air should be considered in whatever alternative you design. |

Are you sure this flow restrictor bypasses the valve? Bentley section 19.10 also says '83-85 "remove flow restrictor from inlet fitting of heater valve". With my Subaru conversion I needed to open the rear valve to provide this bypass function. Perhaps different years had a different valve setup.

Yep, take a good look at a system before you assume anything on it.
Little things add up and can make a difference. |
Yes, I agree. Looking at the coolant flow diagram on 19.10, only the right head goes to the heater. If the bypass were required for correct operation of the engine, why would it only be on one head? So then, can you explain how this restrictor will make a difference?
What about the vans/trucks that don't even come with a rear heater from the factory?
Please, this response is pointless enough, but three posts? At least consolidate all your "X2"s into one post. Sometimes I wish the post counts were not shown like on some other forums; I think it would eliminate some frivolous posts. _________________ 1986 Vanagon Westfalia EJ25

Post whore!
Oops, I am one too now.
Thanks guys, lets keep this to the best method of removal, not a debate if one should remove it or not, or how many posts inSync has lol
Just pretend the decision is made to remove the heater, now which is the best method to execute.

All I ask is that if you have an "X2" type of post, is that you please share some additional valuable information from your experience, so as to increase the signal to noise ratio; also if you have consecutive posts please consolidate them into one post. _________________ 1986 Vanagon Westfalia EJ25

Search the original Vanagon.com email list for valuable info that Dennis Haines posted in the 90s as to why you should remove the plastic Ts and not leave dead end coolant lines in your system when getting rid of the rear heater.
A hint as too why is that they fail about as ofter as the the gasoline bulkhead fitting in the engine compartment.
Get rid of 20+ year old plastic parts that have seen countless heat cycles
RMW has nice upgraded Ts, reducers and straight connectors.
There is a direct correlation between having issues bleeding your system and having dead end coolant lines.
As it states clearly in Bentley, for the bleeding process all heater valves need to be OPEN.
Many use the rear heater loop in there conversion bypass.
If you have a conversion, a reversed coolant distributor and or don't actually know how your cooling system is plumbed...before removing anything, I would get up to speed on the layout. |
