My 2001 Chevy S-10
can u tell me what the high side and low side for my
ac should be






JK:
Hello and thanks for visiting.
With the a/c running, the low side pressure should be around 30-40 psi, and the
high side should be around 200-250 psi. These numbers depend on outside air
temp
erature and underhood temperatures. The hotter it is, the higher they will be to
the high end of these numbers.
