The low pressure port on the 99 Grand am is on the passenger side. It is right against the firewall.
On my 99 Century 3.1l V6, the low pressure port is on the inverted "U" section of the low pressure line on the firewall near the EGR valve.
60 to 66 psi.
I would say that my 1998 S-10 does not have a PCV valve, at all, anywhere.
hi is a blood presure of 99/98 low &also is it dangerous
41 to 47 psi, pump running, engine off.
The low pressure schrader access valve on a 99 caravan 3.3 L is right in front of you when looking down a the compressor. Its on the larger low side return line which is on top coming from the firewall. The high side line usually on the right side follows the path back down under the compressor to the condenser.
60 to 66 psi with pump running, key on, engine off.
On a '99 suburban, the low pressure a/c port is on top, towards the back of the compressor, and pointed forward. The high pressure port is there also, just behind it and to the left, pointed straight up.
under hood, on fuel rail which is connected to each fuel injector there should be a valve that looks like a tire valve. That is the shrader valve, test fuel pressure there.
No. Different generations of S10 altogether.
