A/C Evaporator...

[creekman]

I had a conversation yesterday with a knowledgable Porsche airconditioning specialist, he said that the evaporators for our car are not long lived. Does anyone have any information on the longevity of our evaporators? The reason I'm asking is that I have my engine out and plan on replacing the receiver/dryer and if it's prudent I would replace the evaporator at the same time.

Thanks,

I have not read of many evaporator failures, but they do take a fair amount of abuse being in front of the radiators, soaking up rocks, dirt, gravel, etc.

I haven't read of many condenser or evaporator failures, but there have been a few pulley problems or seizing/etc, but I wouldn't call it a widespread problem, so I wonder where that Porsche tech got his info from, curious to know!

The most common issue I've read about in the forums with older cars is the systems need to be recharged.

I don't understand where he is getting his data from, but unless physically damaged in some way, they are pretty long lived.....

Yea, neither the condensors nor the evaporator are common failing items in our cars. Note the evaporator is inside the dash when the condensors are in the front bumper. Can't imagine how the evaporator gets damaged being inside the dash...
