Heater Valve (again)
« on: February 21, 2016, 12:00:16 AM »
A long time ago, I bypassed the heater core on my TR8 because the control

valve was leaking.  I did put a restriction in the loop, so while water

flowed through the heater hoses, it was limited flow.  I'd like to get the

heat working again by replacing the valve with a generic heater control

valve, but I am looking at non-bypass valves, i.e., when it is off, it is

completely off.  They are abundant and relatively inexpensive and they come

in wire or cable actuated, so it shouldn't be too hard to set up..  I know

that the OEM valve is not completely manual, but uses a temperature feedback

wax(?) module. I am willing to give that up.  



 



I don't know if the OEM control valve allowed water flow at all times, so

the question is. . . . .



 



Does the heater control valve fully shut off the coolant flow through the

heater core and if not, would shutting the flow down completely be an issue

for the cooling system?  This is a stock (at least the cooling system) A/C

car that will eventually have the A/C refurbished and replaced.



 



Thanks in advance,



 



Jack



 



 



Just a quick search found the following, not all of which would work easily.

I was just trying to see what was out there, how they worked and what they

cost.



 



Cable actuated

There was a cross to a Volvo valve that worked, but that became hard to get.

Mark Elbers would know.

Its a heater valve from a 74-99 volvo, but is NLA.  The newer superseding

part does not fit.  Older ones might be found at Voluparts in Atlanta.

Here's what I have archived:



73-93 Volvo part number 1348252-6 superceded by part no. 9131998.  Everco has a part no.

H6345.

Heater Control Valve [A/C]     Ready Aire # 5864

A/C Expansion Valve            Ready Aire# 4680

Application 74-76 Volvo 240 series



But I am told that these parts are difficult to find.  A quick look turned up nothing.  Here is a plain jane valve that might work:

Its been a while, but if I remember correctly, the part we need has inlet  and

outlet at 90 degrees, the everco is straight.  I think this was the problem

with the replacement Volvo part as well.  That Volvo 240 is the right car

though.  The original 240 valve had the mounting holes in the right place as

well.  Voluparts in Atlanta is a large indoor junk yard of Volvo stuff.

Yes, there are a lot of valves which can be fitted and made to work, which

bring us back to my original question.  All of the bPlain Janeb control

valves are more of a ball valve with what appears to be complete shut off.  I

am not sure if the OEM heater valve completely shut off the flow, as I seem to

recall it is more of a plunger design.  Is shutting down the flow off 100% ok

or does the system need some bit of bypass flow?

I cant swear there is no trickle of water running through, but I can tell you

if I leave the fan on and the heater control set at cold, there is no heat

coming out, only ambient temperature.  So, if there is any flow its a nominal

trickle.

I have one of the inline mechanical valves under the hood and shut it off

in the summer.  I rebuilt  my original valve (article in an old TWOA

newsletter) but the rebuild kit only included the external seals not the

plunger that blocks the flow so it does leak some.  I'd say a fully

functioning original valve would largely block the flow.

Thank you to all who chimed in.  Ben's response provided me with what I

needed to know.  Given how difficult it is to find a OEM-type valve, I am

happy going with a simple aftermarket valve and will purse that option now.

They are inexpensive and are probably less likely to fail and leak than

Triumph or Volvo new-old stock.  I just need to find the right valve and

figure out how to mount and actuate it.



Ben, thank you for responding!

Jack, everything I know is on the WWWedge Xref -

http://wedgelist.triumphwedgeowners.org/crossref/



relevant entry:

Application:                          TR7/8

Triumph Part #:                   AAP128

Other Part #bs:                     Volvo 1348252-6, Ready Aire # 5864,

Everco # H6345. Old Air Products H16-5000

Other Vehicles:                    1973-1991 Volvo 140-164-240-260

References:                          WWWedge e-mail list, TR8CCA newsletter



Comments:

As of September 2014, the current opinion within the wedge owners community

is that there is no readily available replacement valve.  The following

information is presented in the hopes that someone can use it to track down

a suitable replacement.



Ranco type H Heater Control Valves for 1973-1991 Volvo 140-164-240-260.

Original part number 1348252-6 superseded by part no. 9131998. The original

part makes the wedges necessary right turn, but the replacement part does

not. Voluparts in Atlanta used to carry a version that works.



See also the TWOA newsletter: issue 16 (Pg 3) for an article by Ben

Zwissler, on how to rebuild the valve using a NAPA Balkamp 6601000 parts

kit.



See also TR8CCA newsletter: issue 53 (pg 16) where Odd Hedberg mentions Old

Air products part number H16-5000 9054 01 Made in UK.



See TR8CCA newsletter:  issue 51 (pg 8) for instruction to repair the

Thermostat switch using Old Air Products replacement parts per a letter from

Bill Sweeting.



See TR8CCA newsletter:  issue 58 (pg 27) for instructions by Peter

Nussbickel, on how to replace AAP128 with a manual water shutoff valve.  The

valve is actuated inside the car via the heater console leavers on the Dash

board.   While the repair was originally designed for an A/C car, this is a

great upgrade to heater only vehicles so you can shut of the hot water flow

through the heater matrix on hot summer days.
