How do you remove a broken head bolt?


I would centre punch mark the centre of the broken stud and with a drill stand, drill a hole down the whole length of the stud, getting larger and larger as I change the bits. When I reach the last threads peel the thread out using a pick. If the thread is damaged, drill oversized to tape to fit a Hellicoil.
The largest Essex Engine was 3.4litre V6, not 3.8. The most common was the 3.0litre fitted to the Zodiac and Capri. It was a V4 with two more pistons and uses the same head bolts etc.

Use 6-point wrenches or sockets to eliminate slip. From your post:

I cannot tell whether the bolt cracked or the bracket cracked from your post above.

Do you have any kind of small cut off wheel?

How do you remove a broken bolt on the timimg belt tensioner pulley for a 2001 300m crysler


!st remove the tensioner if it is still bolted in place by second bolt. Easy outs are high tensile you will not drill through it. You may have to carefully try to chisel it out. If you can get it out try a left handed drill bit if you have room to drill. If it won't come you will probably have to re drill & tap a new thread & use oversize bolt

My alternator bolt broke that hold it to the engine what do i do


remove the alternator and if there is enough of the bolt take a pair of vise grips lock them down tight and remove bolt, if it is a clean break you have a few options:

1) get a set of easy outs, drill a hole and use an easy out to exact broken bolt

2) get an oversize self tapping bolt (a size bigger then the bolt that broke off, drill the bolt out completely and then tap the new bolt

Good Luck Tim

How hard is it to replace knock sensor on 2000 outback


Instructions Things You'll Need:
  • Metric combination wrench set
  • 3/8-inch drive ratchet wrench
  • 12 mm socket
  • Knock sensor
  1. Open the hood, and disconnect the battery negative cable with a wrench.
  2. Locate the black rubber air intake tube that runs from the air cleaner box to the throttle body on top of the engine.
  3. Loosen the clamp on the air intake tube at the throttle body with a wrench. Grasp the tube and pull it off the throttle body inlet, and move it out of the way.
  4. Locate the knock sensor. It's bolted to the engine near the throttle body. Remove the hold-down bolt attaching the knock sensor to the engine block, using a 3/8-inch drive ratchet wrench with a 12 mm socket attached.
  5. Follow the electrical lead of the knock sensor to its connector, and simultaneously lift the plastic tab with your hand while gently pulling apart the plug.
  6. Remove the knock sensor from the engine bay. Compare the old sensor to your new part to ensure they are identical.
  7. Reattach the knock sensor to the engine block by threading in the original holding bolt by hand. Snug the bolt with the ratchet wrench and 12 mm socket. Do not over-tighten the bolt.
  8. Plug the new knock sensor into the original electrical plug.
  9. Gently push the throttle body air intake tube onto the throttle body. Tighten the hose clamp with a wrench.
  10. Reconnect the battery's negative terminal with a wrench. Close the hood.
  11. Start your Subaru's engine. Take the car on a test-drive and verify that the spark knock has disappeared.

Bolt broke off inside side mount battery. how do i get it out


Go to the parts store & get a bolt/screw extractor.

It works by first drilling a small hole into the bolt you broke, then you screw the extracter, counter-clockwise into the bolt & it will back it out. Soak the broken bolt with lubricant/wd40 before trying to extract. Don't drill more than the depth of the bolt.

good luck.

I have a 93 crand caravan the water pump went out and in the process of changing it bolts broke how can i fix it?


If the bolts broke off inside the engine block they must be extracted, buy a easy out set of bolt extractors choose the appropriate size drill to use in relation to the broken bolt to be removed then dril a hole through the old broken off peice remaining inside the bock take the easy out extrctor and push it into the drilled hole then tap it into the hole firmly proceed to tur n the extractor counter clockwise to remove the broken off peice. whatever you do don't use an extractor that is too large it may not work you can always go up on the size later.

I broke one of the bolts to the thermistat housing, tried to drill it out and screw out with an extractor, but unsuccessful, any ideas? What is the larger part that the thermistat housing bolts on to, I...


True using extractors is sometimes more complicated than bringning it to the machine shop, but the most logical since there is no drill press at hand. But you do not need to retap, just tell the machinist to remove the bolt and use an insert with inside and outside thread already so the casing will not be damage.
