What does a service valve on a GM car do?
The service valves allow the service technician to evacuate and recharge the refrigerant in the A/C system. This A/C service valve is a GM-recommended replacement for your vehicle’s original components and has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
Why do I have a burnt valve on my car?
Incorrect Valve Seal – for whatever reason (wear, weak spring, valve lash etc) – reduces the quality of valve-seat contact and hence impedes heat dissipation (through conduction to the head). Improper guide and/or loose seat can contribute to this.
Can a partially burnt valve affect fuel economy?
A partially burnt valve will be difficult to notice but will produce anomalies in the fuel economy.
Can a blown head gasket cause a burnt valve?
Just remember, no method is foolproof. If the leak is small enough (whether blow-by, burnt valve, or head gasket), it can affect performance, but not truly give any real signs. It will, over time, rear its ugly head so you can see it though. Catching it early is far better than waiting until things get out of hand.

How to know if the EGR valve in the 1994 Chevy is bad?
