I have a 1947 CJ-2A with no heater. Noticed that there is a manual heater control valve on the cylinder head. A hose goes from the control valve to lower radiator hose that connects the radiator and water pump. Can I remove and plug the control valve with a bolt and only have the lower radiator hose to the water pump connected?

Jeep just started engine die when let off accelerator. Idle it up at carburetor it stays running but idling too high. !957 CJ7 4 cylinder.

You need to check your timing and probably have low vacuum. At idle (approx 475 rpm) once warm you should have 20 inches of vacuum draw with no choke.

Does this piece attach at the water pump? I guess i have an aftermarket water pump on a CJ-3A L-314 with 2 valves, one going to the non existent heater unit which needs to be plugged.

I see you have the manual shut off valve for the heater. Do you have the shut off valve that mounts on the firewall and is controlled by an inside cable. This is on a 1957 sw,L6-226 ?
Willys Jeep Parts Tech:
This part is the manual shut off used on the head. Any others would be used only. This could be used in a number of places however with the right fittings.
