jazic3.4 Posted July 8, 2005 Report Share Posted July 8, 2005 I have 2 questions: 1. How can you tell physically if you have a faulty Tension actuator? 2. Can you physically compress the actuator using your hands or vice? Quote Link to comment Share on other sites More sharing options...
Turbocharged400sbc Posted July 8, 2005 Report Share Posted July 8, 2005 dep on the vehicle...honda's will need a vise...some chryslers at supposed to be vertically compressed so you need a vertical press or a vise mounted on the side of a bench.... oh waita minute you might be asking about the 3.4L (not sure, though no info in your post as to what vehicle, engine year etc....) the 3400 doesnt have a timing belt! the 3.4L DOHC LQ1 does... if you are refering to the 3.4L LQ1 these tensioners will seize (if not lubricated with sythetic oil when the T belt is replaced) but not too often do they weaken it is a spring and screw style tensioner... 1. If the Timing belt is real loose...either an idler pulley etc went bad or the timing belt has stretched or the tensioner is seized 2. The 3.4L tensioner has to be put into a vise (GENTLY!!!!!!!! you are trying to make it so the body of the tensioner doesnt rotate! clamp it too hard and buy a new tensioner!) the base plug removed a small flat blade screwdriver inserted and rotated clockwise to screw in the tensioner, then you have to insert a strong small diameter piece of steel/wire into the plug diagnal from the end plug and slowly release the screwdriver 1/4 to 1/2 a turn while pressing in on the wire till it locks into a grove and will prevent the screwdriver from spinning wildly when you let go, if it does start over... next time post more info on year make model engine...
