Exhaust or vent gas may be released if a valve is dismantled from an oil pipe system. This is produced as pressure build up in the system over time and can result in rapid pressure release.
a gate valve is a one way totally open or closed valve, a control valve is a variable valve.
Colorados do no not have a PVC valve, they use a fixed orifice system. The PVC pipe is the main componet of the system. Checking pipe for leaks is the only service listed.
The coolant air bleed valve is located on the top of the thermostat bypass pipe/heater pipe assembly. Close the valve once a continuous stream of coolant is expelled from the valve.
The exhaust valve, the exhaust manifold, the header pipe, the catalytic converter, the muffler and the tail pipe, not to mention the clamps and hangers.
Flare copper pipe and use a flared shutoff valve. If valve isn't flared, use an adapter fitting between copper flared pipe and valve.
npt, national pipe thread, is a standard for threads on a screw. I (not a plumber) don't believe "npt valve" makes sense , but probably refers to a valve which has npt threading.

It depends on the type of system you have. 1 pipe in, or 1 pipe in and 1 pipe out. Single pipe in/out, try replacing the relief valve or simply shimming the end of the radiator opposite where the pipe comes in. This lets water bleed out of the radiator and stops the klanging.
try an "internal" pipe wrench, these can be purchased at mscdirect.com, they have a cam on them that grabs as its turned inside of a pipe.
I'll give you 4. The Float System, the Fuel Jet, the Venturi Pipe and the throttle valve.
Yes, clean the cabor buildup from the EGR valve and that pipe.
the suction valve is transfered fluid one pipe to another pipe at a specific pressure and quantity.
