Heater valves

[Mark Woodland]

After the heads up on the heater valve issue, I cruised on down to Autozone
for two, for Max and Gina. ('87 and '86 5KTQs)
Turns out one was all metal and the other was half metal, half plastic.
Both had the same part number.
I got the metal, and left the conglomerate..
Moral: open the box and check before buying.
Or, better yet, call ahead and have them check it out.
Does anyone have any input/data on the half metal/half plastic?
best regards, and, as always, thanks to the list.
Mark
