Excursion compatibility for ball valve max ac mod?
Plastic heater valve is leaking in my Ex. Can I replace with a 3/4 manual ball valve like we do with our trucks without a factory valve and just cap the gray vacuum line?
Not worried about price. Just reliability and availability. Oem valve is 3hrs away in stock or a 3 day ship. Aftermarket valves are worthless. A trusty manual ball valve is local, cheap, and just about fail-safe - all appealing for a daily-driven Excursion. Was hoping someone had done it.
Well... i was reading about putting the vac valve in my SD, and from the discussion there, my understanding is the ex, and SD have the same system, except for that valve on the ex. Im actually putting in the ball valve on my SD, when i do my coolant flush and filter install. Bought the valve friday.
What David said. I've been using the same basic valves in a Rangers for years. I've only ever had one fail, and it wasn't even a failure in use. I was replacing old coolant hoses on the 99 Ranger many years ago, when trying to separate the hose from the valve I managed to break off the nipple on the valve. Prior to that it was functioning fine and not leaking.
Excuse my ignorance of how the system flows/works. My Excursion oem valve has only 2 lines, an in/out on the valve.
The added gray vacuum line and excursion rear heat/ac controls that differ from my 350 are what I am not sure about regarding my ability to retain functionality if I change it up.
I am in the same boat as David and Josht. I have been using the Ranger (very similar to the Excursion) valve for many years without fail. I know for a while people were having all sorts of problems with it leaking, but people only come here to complain sometimes. After a failed attempt to use the Diesel Site Max AC Assist dohicky, I installed the Ranger valve. Been great going on 5+ years now.
CousinCarl, your question is not a bad one. The valve you have does the same thing as the 4 port valve. Yours only cuts off one hose from flowing where the Ranger valve cuts off flow from both hoses. The Diesel Site valve only cuts off one hose too. A lot of people that install the PEX valve only cut off one hose, some do two.
Same result based on stopping coolant flow from or to the heater core.

The OEM Excursion valve shown above is the same valve that Ford installed in pickup and chassis cab 7.3L Super Duties in 2002-2003.

Yes you can. That's what I did.
I went the "Ranger valve" and had both of them eventually leak on me. After that I went with the manual valve and never had any problems.
