Is there a way to test for a leak in the AC system if the system has already been drained?
The compressor seems to be locked up because the car stalled out immediately when the AC is turned on and I could smell burning belt. So I couldn't test for leaks with the system running. Probably should have tried the test before the system was drained even if it was not running but too late now.
I'm doing a heater core replacement so I have access to the evaporator. I'd like to test it to see if there is a leak before I put everything back together.
If you're not familiar with what's involved in a heat core replacement which would be very similar to an evaporator replacement check these DIY:
I could just go ahead and replace it but a new evaporator would cost $200 at germanautoparts.com so I'd like to avoid the expense.
