Muchos coches no tienen una válvula de agua caliente cuando sale de fábrica.
El aire acondicionado frío y cálido es controlado por el motor de control de conductos, no se siente cuando en climas fríos. Pero cuando el clima es caliente, porque su aire caliente no está cerrado herméticamente, algo de aire caliente irá al aire frío, lo que afectará el efecto de enfriamiento, y el consumo de combustible aumentará obviamente. Después de instalar la válvula de agua tibia, el agua tibia dentro y fuera no circulará, y la temperatura del tanque de agua caliente en la cabina disminuirá naturalmente.
Precauciones de instalación:
Después de que el coche esté frío, se puede instalar. Después de la instalación, gira la válvula de agua al modo de invierno, comienza y añade refrigerante. Después de unos 15 minutos, enciende el engranaje de aire caliente en el automóvil, enciende el ventilador y luego apaga la válvula de agua después de que se sople el aire caliente.

Perfect valve for an optional heater core bypass. Installed it last summer and have had no problems. Had it open all winter and switched it back to bypass recently.

Works great, easy to install. The cab of my 1993 F150 is cooler in the summer now.

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.
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.
