Cooling/Hydraulics 101: PO=oops..help

[jackb]

Chugging along on my 63' Cruiser. Got the drivetrain back in on Saturday and found out a pair of NOS tranny mounts were wrong...well at least the driver's side is wrong.....Grrr. Right now I've got a block of wood under the driver's side mount until new one's arrive....Anyway...I rebuilt the Ranco heater control valve (thanks to Tom B. for excellent directions)and hope it doesn't leak, and that brings me to my next problem/question ? I think the PO screwed up the hose routing of the valve, or at least it doesn't match up with the manual's hose routing diagram. I didn't realize it until after I had trimmed the molded hoses under the dash to install & connect the valve. It appears I've got things backwards.....So to the point: How does the water pump, it's heater hose connections, the valve, and the heater core operate ? And more important: does it matter if you reverse the hose connections on the valve (i.e. will the flow be compromised in any way. My hose connections go this way: from the upper tube on the water jacket to the 45 angle tube on water valve-out the straight tube on the valve---to the rear pipe of the heater core---out the core to the lower water pump connection.

Not sure on a Lark but I got them backwards on a Avanti and blew the heater core.

Heater hose Routing....

Ok...good input. I did follow the thread to the LeVesque post and find that I have placed the control valve between the pressure fitting on the water jacket and the core....Now...I have the connections reversed...The plunger (inner valve) that controls the flow through the valve is located in the "straight" tube of the valve.
Correctly routed, the hot water is restricted or shut off by the dash lever there and little or any gets by to the 45 degree tube....As I have it routed, the pressured water comes in through the 45 angle tube
slams up against the new seal I installed and bounces back down the into the straight tube. Anyone see any problems here ?

Jack, was the heater control valve hose hook up ever answered? I have the same question, does the pressure hose attach to the "straight" outlet of the control valve or to the 45 degree outlet?

Jack and Kerry; the 45 degree tube on the heater control valve of '62-'66 Lark Type cars is the one that gets the short (3 1/2"-4" on each leg)"L" hose that goes to the forward tube on the heater core.

That leaves the rear heater core tube getting the hose to the Water manifold LOWER fitting (return).

And then the straight tube on the heater control valve would have to go directly to the (Hot) output, the UPPER water manifold fitting.

I did not think that the title of this post was appropriate for people looking for help on the subject, so I posted a new post with this info and a better title for the search engine to find it as an Archive item.
