Expansion valve operation

Postby jromanec » Wed Jun 29, 2005 9:39 pm

Can someone please explain the operation of a Chrysler H block expansion valve. Is it a fixed rate of freon release? or variable? and how is it controlled.
I don't see anything going to it other the the 2 freon lines.

Thanks in advance

Internally equalized TXV you will notice that both the liquid line and sutcion line run thru the block, non serviceable, throw it away and install another one if you are having problems with it. What are the symptons?

Internally equalized TXV whats that mean?
symptom prior to having the evaporator core and expansion valve replaced at a chrysler dealer for a leak in the evaporator core only that failed earlier this month my vent temps where always able to get to 45deg in rec mode now after the repair and 2 follow up visits to the dealer where everything checks normal the vent temp in rec mode will only get to 52 deg in high fan position. if I use the normal second speed it will raise to 60deg.
I'm just looking for things that may have to be rechecked by the dealer and also my own knowledge.
