Default Re: Solution to diminished AC performance after evaporator core replacement

Maybe I was imagining the screen.....
I could swear my unmolested 92 had a screen between the blower fan and evaporator.
I scoured the internet looking for pics, but could not find an example.

Anyway, here's an extreme example of a clogged evaporator.
https://www.corvetteforum.com/forums...and-after.html

Not a lot of air flow before cleaning.
Mine was only halfway clogged on the bottom half @ 20,000 miles.

If anyone needs a new evaporator, these guys make them with the correct bend in the bottom tube for ZR1. They make them per order. Excellent workmanship.

This is an example of what I used in my 92, converted to 94-95 R134a system.

GC,
I?ll do it all one time when I replace the heater core and upgrade the wiring and alternator since I have the spal fans now and upgrading the stereo a little. Man, those spal fans let you know when they are on! 😆 I finally drove it today since the install.

Fer sure. It cools it down quick. I think they improved the shroud and seal to radiator so it works great. My highest temp was 209 all day but only 90 degrees outside. I?m happy!!
