Question Answered: 

When the heater does not work and the engine runs hot, it is probably a sign that you are low on coolant. The best way to check radiator is when vehicle is cold, take the cap off radiator and look there. Sometimes the recovery tanks so not work and the fluid will not go back to radiator.

When engine is cold, and if you have a expansion tank system, check water at radiator cap. My guess is low coolant too. Could be if you have a bad cap or something is loose on line to expansion tank, coolant will not return to radiator. Also look for a small leak if radiator level is down.

Could be the return line clamp, as hose goes into the bottom of the fluid reservoir.

You might try this. If engine runs rough all the time, while it is idling, disconnect one spark plug at a time. If engine runs the same with that plug disconnected, and does not get worse, you probably have a bad plug, bad wire, bad individual coil, or bad injector.

That noise when you engage the front axle and make a turn is what you hear when a CVC joint is going bad.

Some Ford trucks have a vacuum operated valve in the heater line for the front unit. Check lines to and from unit by feeling if they are hot. If not valve may be bad. If lines are hot then it could be a Blendoor or possibly a control problem.

On a lot of GM cars the water bypass is through the heater core, as the heater coil is always hot. Feel in and out lines of heater hoses and see if they feel hot, if not heater core could be blocked. Once engine is hot the thermostat should open and you can feel top hose getting hot. And water should then be circulating through radiator. Like mentioned, it could be a bad water pump too.

Another possibility is the oil pressure switch. If Engine starts and runs a few seconds then dies this could be your problem. Fuel pump comes on for a few seconds to start car, then the fuel pump circuit is thorough the oil pressure switch. This is so if you loose oil pressure, car will shut down and engine will not be ruined.

This is how I adjust mine. On a level surface, drive car up to a wall or garage door and stop about 2 feet from surface. Turn lights on and mark an 'X' with tape where center of beam is. Back up about 20 feet and see where center of beam is now located. Lift hood and if you look at headlight assembly, you should see up/down and side to side adjustment screws. Just adjust lights so that center of beam is just a bit lower the 'X' and centered side to side on 'X'.
