what would like to know?

Typically a coolant sensor failure will result in the engine cooling fan running constantly. This will cause the engine to run cool and use more fuel. As long as the cooling fan is running there is not a great danger to the engine if it is not overheating.

Yes, it would.

The engine cooling fan is located on the front of the engine between the radiator and the engine block. You do not feel it through the ac vents.

tranny shift code

It depends on the code. The code could mean the fuel system is too rich or too lean. Its possible the sensor is not working too.

Gm security systems are a common problem. They are a great idea just arent made well enough to last forever. Best idea is to get it fixed, but the cost is extremely high. If you must bypass the system (which is fine and wont hurt anything) there are a couple different ways that i know to do it. Check out this link and read up on the problem and the different ways to fix this. http://vatspasslockpasskeysecurityhelp.yolasite.com/

there are two bolts that hold the power steering pump in place that are accesable through the holes in the pulley. If you use a 6" extension and a 1/2" socket you can reach them. this will allow the pump to be removed and hang by the hoses and be out of the way. I was told also to inspect the cam sensor while it is apart because you have to remove the water pump in order to get to it.

sounds like the oil pump is weak or the oil filter needs changing

Bad ignition switch or a bad/loose connection at the starter

do you have a code for those solenolds or are they just quesing,if no codes they are tring to screw you

A large noise made during turns could be a bad CV joint. They are what the car uses to connect the wheels to the engine.

A local mechanic can check your CV joints protective coverings or "boots". These boots can be torn and the grease that keeps the joints quiet may have leaked out of one or both of them.

You can look yourself at the outermost boots and see if one of them is all greasy and dirty. A good sign it has leaked.

I hope this helps. Good luck and be careful.

check fuel pressure

Find a way to get your hand on the back of the headlight assembly from under the hood. Depress the tabs on the socket on the rear of the assemble and rotate counter clockwise then unplug the defective lamp replace with a new one being careful not to touch the glass on the new one with your hands or anything oily.replace the socket and turn clockwise until tabs lock.

if the bolt is hitting the frame rail or the motor mount the only thing you can do is put a floor jack under the engine to hole it and take the motor mount out and raise or lower the engine to remove bolt
