I am not exactly sure of what you are asking but there is not an evaporator valve. There is an evaporator core that resembles a radiator and there are not any parts that can stick. The only problem they have is leaking. There is an orfice that goes in the inlet to the evaporator and it has no moving parts.It can get stopped up and cause the high side pressure to get higher than normal.
Yes they can and do stick. I suggest that you take it to a certified repair shop as low heat is sometimes needed to remove it. To much and you melt the connection.
No its an automatic
No
Some do and some don't.
the dip stick
No I dont think so.
if its a manual tranny there is no dip stick, if not then it will be on the drivers side of the motor by the firewall.
Not properly. It is too wide, however the 67 has a radiused wheel well, and the tires can stick out, and function. You are only 1 inch wider, so it would work. You may have to change the rear u joint in the drive line also......Chuck.
Add it in the transmission dip stick tube.
It is a physical change as there is no change chemically in the composition of the stick
There shouldn't be any difference
If your talking automatic no but if your talking stick shift it will.
