Hello Danny, when you replace a tensioner you normally replace the belt as well, i would check the ac unit clutch assy for faults for there might be faulty bearings at the clutch assy there should be no play or warble in this assy, check with the belt removed, to check belt tension you should be only able to twist the belt about and no more than half a turn with you hand at the location of the largest span between pulleys with the belt installed
I have a radiator leak on the bottom of the
Coolant leaks can sometimes be difficult to locate the exact origin of the leak. That is why proffessional technicians use pressure testers, bright flashlights, inspection mirrors, and in some cases even borescopes to locate the cause.With that said, I would say that if you have a "radiator leak" and it is "on the bottom of [your] radiator" my first guess is that it is coming from the radiator itself....check the area of the radiator where the plastic tanks are crimped to the cooling tubes (main radiator core). Sometimes the fittings in the tanks leak where the transmission cooler lines connect. I have also seen leaking radiator caps misdiagnosed for a leaking radiator....Sometimes they will leak and the antifreeze will run along the sides of the radiator and "mimick" a radiator tank leak. Remember, the coolant almost always travels DOWN and REARWARD. Sometimes it goes way to the left or the right, but it still goes down and back from there.A bright flashlight and an inspection mirror will verify most leaks. You may also want to detach the fan shroud and move it back for better inspection of the radiator. - start where you can see the coolant and follow the trail upward....
GM OBD2 code 1345 causes
either the crankshaft sensor needs to be changed or camshaft sensor.Both work together and are under that code.If you change the sensors you will need a crankshaft profile correction.This should be done by your dealer with the proper scan tool.
How to turn the security light off
The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. (Theft Deterrent Module) The TDM is what tells your computer that the correct key is being used and that it is "OK" to allow the vehicle to start and run. These 3 parts must be in CONSTANT communication. If the key is in the ignition, then these parts are sending important signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, (normally due to a failing/broken part) the car goes into antitheft mode. The car misinterperates this and thinks its being stolen or hotwired because it is NOT getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle. So basically, if that light is on, your system has some sort of failing part. This can start as an intermittent "no start", to your vehicle not running for days at a time, to the vehicle NEVER starting again. The problem is electrical and computer based, so don't count on an easy reset button, or the problem fixing itself. The hard part is isolating which part is the problem. You can spend a thousand dollars through a mechanic very easily. I have had great luck with bypassing the entire system. This way the problem will never return. It actually CAN'T ever return because it is eliminated. This can also be done yourself at a much cheaper cost. Read through this link very carefully. You'll find alot of information and pictures, along with ways to help you fix this.
