azmichael1 Posted March 9, 2011 Report Posted March 9, 2011 (edited) On my ,48 P-15 on the top rear of the cylinder head there is a water control valve (called watercock maybe ?) that controls water to the heater.... can someone tell me the proper name of that and where I might go to get a replacement ? Thanks! Mike '48 P-5 Apache Junction, Arizona Edited March 9, 2011 by azmichael1 misspelling Quote
oldodge41 Posted March 9, 2011 Report Posted March 9, 2011 Heater shutoff valve. Vintage Power Wagons have them here http://www.vintagepowerwagons.com/pdf/parts/05cooling.pdf look on the bottom of page 25.............Tim Quote
TodFitch Posted March 9, 2011 Report Posted March 9, 2011 Heater shutoff valve. Vintage Power Wagons have them here http://www.vintagepowerwagons.com/pdf/parts/05cooling.pdf look on the bottom of page 25.............Tim $26.50? Ouch! Napa Online shows the very similar BK 6601402 for $11.99 (5/8" hose) or the BK 6601401 for $14.99 (3/4" hose). Just do a lookup for "heater valve". Last time I got one of these I simply walked into my "local better auto supply" and picked it out of their paper "truck heater parts" catalog. They had it on the shelf, no need for mail order. Quote
Chester Brzostowski Posted March 10, 2011 Report Posted March 10, 2011 Was there a cable hook-up to the dash that controlled the water on/off function? On the driver’s side of my heater control panel I have a blank knob that says temperature control which my assumption is that this was to replace a possible option ? Chet… Quote
LAKOTA169 Posted March 10, 2011 Report Posted March 10, 2011 Mike, just to jump topic for a second, we have relatives in Apache Junction. A niece and her husband. Robin and Terry Baugher. Also one of the local car cruisers spends the winter months there. Quote
James_Douglas Posted March 10, 2011 Report Posted March 10, 2011 I used a stainless steel ball valve. I used the arm off of the original heater control vale and made a steel plate which bolts to the valve and hold the cable... If interested let me know and I will dig up the part number and vendor.

Phil Martin Posted March 10, 2011 Report Posted March 10, 2011 I went to local parts store told them what I wanted. He went and got it off the shelf. Can't remember price but was surprised it was so cheap and easy to find. Quote
WatchingWolf Posted March 10, 2011 Report Posted March 10, 2011 Eaton Weatherhead has the manual valve listed in the Vintage Power Wagons catalog as well. About 1/2 the cost at our store. I believe about $13.00, but I would need to verify that. Quote
BobT-47P15 Posted March 10, 2011 Report Posted March 10, 2011 (edited) I got a manual one at O'Reilly Automotive store. Dont recall the cost, but not bad. There is a cable operated valve also.....harder to find & cost more. Old one that was on an engine.........new one from auto supply. A cable operated valve just to the left of the door handle escutcheons......... Edited March 10, 2011 by BobT-47P15 Quote
Jim Saraceno Posted March 10, 2011 Report Posted March 10, 2011 I just installed a cable controlled heater valve. It is hard to see in this picture but the NAPA part number is there. This way I can turn the heater on and off from inside the passenger compartment. As you can see, it is inline the heater hose. Out of the block I just have a straight fitting. (This picture was taken before the cable was installed.) Quote
claybill Posted March 10, 2011 Report Posted March 10, 2011 a mechanic did a test on my motor and found that there is a 10degree difference in the head temp around the back cyl if that is turned off during summer months....not allowing heater water to run thru.. just info .. he used one of those hand held red light heat/temp infra-red things..???? bill Quote

But I've felt that leaving the flow through the heater would help keep the exhaust valves on cylinders 5 and 6 a bit cooler. So while I have a valve on the heater circuit, I leave it open year round. It would seem to me that the 1935 and up engines with the water distribution tube that this would be less of an issue. Quote
WatchingWolf Posted March 11, 2011 Report Posted March 11, 2011 maybe a three way valve would help....one port through the heater and one looping back to the pump.....hmmm. Gotta check the shelves tomorrow. Quote
Robert Horne Posted March 11, 2011 Report Posted March 11, 2011 maybe a three way valve would help....one port through the heater and one looping back to the pump.....hmmm. Gotta check the shelves tomorrow. I have a valve like what you mentioned from a Ford Ranger. Has 4 connections. I have not tested it, but I believe it should allow hot water to flow to the pump when water is not going through the heater core. Quote
WatchingWolf Posted March 11, 2011 Report Posted March 11, 2011 Gotta quit bringing work home with me.....this one is only available in 3/8 and 1/4 inch from Weatherhead but I can source it in 1/2 and 3/4 inch elsewhere. 5/8 is hard to find, but the 1/2 one should flow fine. Quote
