Rear Heat Output in 2000 Suburban


Posted by mpanek on September 25, 03 at 05:03:48:

Does anyone know what the output temp should be from the rear heat unit?

I did some temp readings last night, I get 150 degree air out of the front vents on full heat, and I get 93 degree air out of the rear vents on full heat.

It has never really been a problem I usually use the auto climate and set the temp at 74 or so and it always gets warm enough.

I just flushed out the dexcool and replaced with green and in the process I wanted to flush both heater cores so I had both on full hot, and then left them there to circulate the new coolant.

Just seemes like the output temp should be higher.
