DIY - Aftermarket Evaporator Installed In A Coupe ↗
With original E9 evaporators hard to find, a member fits a commercially available evaporator and expansion valve (O-ring fittings) into the stock A/C box. It comes with a parts and sources spreadsheet, photos of the box modifications, and a reminder to check the refrigerant charge, condenser and flap seals before replacing parts.
Tools mentioned: A/C service equipment, basic fabrication tools
Replacement with a non-BMW evaporator; the box must be modified.
