Default heater control valve(4 port)

does anyone know of a better valve? i have a 2002 2.3 and it seems that every year or so it leaks.i tried one from advanced ,ford,autozone,etc and they all leak over the same amount of time.i got the truck with 10k when i bought it and that valve lasted the longest almost 8 years.i even changed the overflow cap thinking it was bad,no change.thanx for any help.

Its a piss poor design. I tried one from Advance and it leaked out of the box. Doing a pressure check on my system suggests the truck itself is fine: on a 90 degree day idling with the A/C on itll go up to 11psi, but the duratec runs at 208 anyways (which is pretty hot).

I have a motorcraft one now and it doesnt leak, so hopefully I wont end up having to change it every year like you have.

All this said, if it gives me problems anytime soon im going to try to find a metal one that will work. All this plastic crap really seems stupid for a high stress cooling system like that found on our trucks.

BTW, on the aftermarket ones that have the screws, you can try tightening the screws down 1/4-1/2 a turn and see if that helps at all. You can also disassemble it and try some rtv around the shaft or getting a slightly thicker oring.

You can always delete it, the previous owner of my ranger did that everything worked just fine without it.
