Anyone have any tips on screw extracting? I have never done that and it is a tight fit(if you know what I mean). JK
- Get the "square" rather than the "spiral" screw extractors.
- NB: Select a drill bit that is just slightly smaller than the diameter of the 'core' of the bolt that you're extracting, (do not include the thickness of the threads in the diameter). Do not necessarily use the size of drill bit recommended on the package of the screw extractor - it all depends on the bolt that you're removing. If you use a bit that is too small, you won't have enough leverage to unscrew the bolt and you'll break the screw extractor in the bolt (then you're really 'screwed' - pardon the pun). If you select a bit that is too large, either your drill bit or your screw extractor will eat into the threads in the bolt-hole and you'll be stuck either drilling & tapping a new bolthole or helicoiling it (both of these have significant downsides).
- Use a counter-clockwise (left hand) drill bit, so that if the bit bites on the bolt, it'll come out rather than getting further tightened in.
- Drill a hole all the way through the exact center of the bolt.
- Tap the extractor into the hole you've drilled with a small hammer.
- Turn the extractor counter-clockwise to remove the shell of the bolt that remains, using either the screw extractor "T" tool, or 2 small crescent wrenches (one on each side). If the extractor didn't 'bite' on the bolt shell, tap it in a bit harder with the hammer.
- Get a pro to do this if you're unsure.
It is the tensioner that is just below the cam gears and faces the front of the car; not the tensioner that faces the ground.
That doesn't help. There are 2 tensioner pulleys "below the cam gears", but only one is for the timing belt tensioner. They both face the front of the car. The timing belt tensioner pulley is behind the plastic timing belt cover, and the accessory belt tensioner pulley is in front of the plastic cover. The timing belt tensioner assembly has 3 bolts: 1 that the pulley swivels on as it applies tension to the timing belt, and two that hold the tensioner to the block. Also note that there's a tensioner 'shock absorber' located in front of the accessory pullies - this dampens movements in the accessory belt tensioner, but does not appy any tension to the accessory tensioner pulley.
