All Solid Brass Body Automobile Integrated 4-Way Heating Water Manual Control Valve
Solid Brass
All brass body (brass ball core, brass stem). The electroplated handle is strong and durable. So high temperature resistance and no rust, suitable for high temperature coolant environment.
Integrated
No screw fixation, integrated structure, no water channeling, good sealing. In some models, after a long time, the pipes are aging and the elasticity becomes poor. It is necessary to apply some high-temperature sealant or wrap some raw tape to improve the effect.
Application
One of the biggest uses of installing this valve is that the warm water from the control valve is sent to the warm water tank in the cab. With this warm water valve, the water from outside will rarely enters, and there is no need to worry about the dry phenomenon of the warm water tank. In case the heater water tank is broken or aged, the leakage will not cause the engine to pull, cause more damage.

Works as it should

Finally a fix for my truck always blowing hot air thru the vents. Installed this in front of the firewall to reroute hot coolant straight back to the radiator, bypassing the heater core. Just reach in and rotate 90 degrees in fall to turn the heat back on til spring.

I used this to block off a heater core on my 1997 F250. AC is colder than before. Also wrapped AC lines with insulation from the hardware store. This item is solid and appears to be well made.

An old timer told me about using one of these to help make your air icy cool in the summer time in the south.If you don’t have your coolant all drained out it will make a mess to install but mine was already drained to install a new heater core soI did it at the same time.Good quality, valve moves nicely. Will test it this summer as I installed it in winter, but it does work to return the hot coolant before it gets into the air box. So the dryer and condenser don’t have to try and fight the heat from the heater core.I installed it on my 1994 f-150. Really straight forward if you can get to your heater hoses on any vehicle though. Learned about it on a backhoe, so it should cross to just about anything with a heater and A/C.Just make sure you mark your hoses before you cut them so you don’t get them crossed. Probably won’t make a difference but there are no instructions in the box, that’s what I did and it worked.

This works great! I needed this to keep the heater core cool so my AC will cool the inside of my truck. The hot/cold door actuator is busted and this is like having a new truck. I can stay cool in the summer heat.

Our old conversion van was blowing hot air through the rear AC. The evaporator was an aftermarket unit that was no longer supported. Installing this bypass valve in the heater hoses did the trick. I had to change out the antifreeze anyway, so cut the lines and installed with hose clamps.The valve takes quite a bit of force to operate, but we will likely only be using it once or twice a year.The rear AC now blows ice cold.
Often Disappointed!

Looks like a quality part.I used this on my 34 year old Jeep MJ to keep hot coolant from circulating through the heater core in the cab in summer. The factory valve is no longer made and the third party plastic valve I tried WAS JUNK… fell apart in just a couple years. Only luck kept my from being stranded. You do have to open it manually once in the fall and close it again in early summer, a very very minor inconvenience. In winter it allows coolant flow per normal to the heater core. in summer it still allows proper flow but redirects circulation back to the engine, bypassing the heater. Quick easy install. I was able to use the existing hose clamps. Don’t forget to plug off the vacuum line that controlled the factory valve, I used a screw! There were no instructions but simply operating the valve and blowing through it will determine the flow path. I highly recommend trying this. Of course only time will tell how well it last long term.
