Bought new CVRSS shocks. Whats the methodology for testing the ELC or lines for leaks? And if it does need replacing what is the part#?

At this point im not sure if i want to install them yet until i can get new struts for the front. Should i just go ahead and replace the ELC given that it's possibly the original. 153k on the power train, if that helps

Thanks!

Get the compressor to run and pressurize the lines and shock bladders. Then spray with soapy water. A leak will foam.

I dont see a diagram in my alldata for which lines i should spray or wven the ELC itself although i know where to look for it, just not sure where exactly i should spray to test

One more question, the ELC doesn't run lines to the front struts also, just the rear. Right?

Yep only the rear shocks its pretty simple to inspect those lines..... Also if they were still good in my 1984 sedan deville when I sold it I would bet yours are fine

Vincent, look at the compressor, there is the intake line (the only line made of rubber). In the picture from Post #4 the intake line is shown pointing up in between no 8 and 9. Near the compressor this line "T" in 2. I bet you is already dried and broken at least in one place. Make sure you replace it with appropriate vacuum hose (you need 2 feet). That is why the compressor or the exhaust valve goes.
