Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. Can you give me a little more detail about the issue you are having and why you are clamping hoses by the duo valve ?
Customer: replied 1 year ago.
Valve has been tested and is bad. Hot air was blowing out of the side vents when ac was on. The monovalve has been removed. Air is working fine but they do have something with the hoses right it is running hot

Ok how hot is the car running ? Anything between 80-100c is ok.

Goes over 100 went into the red I am thinking thats around 120 do you know what hoses should be connected, and the two bottom hoses and the one one the front is the ones that have been capped off
Expert:  Lou P. master tech replied 1 year ago.
Actually the duo valve hoses have nothing to do with engine cooling. I will have to check a few things to see the hose positions but when the duovalve is shut off it blocks flow only to the heater core. The car cooling system still operates either way. Your issue is not with the duo valve.

The back bottom two are blocked and the one on the upper is blocked
