2006 Scion tC 4 cyl Manual 50000 miles
Bearing sounds like its going on bad on either the tensioner or the water pump. I have a friend helping me that has quite a bit experience with car repair, so we tried replacing the tensioner, but the last bolt holding it in was too long to remove (it hits the frame of the car). Its very close to coming out, maybe a thread or two holding it on. In other forums (scionlife. Com) I had come across an article that mentioned having to rotate the engine to an extreme angle by loosening the s-pipe bolts and then the tranny bracket and the rear bracket. That seems like a rather worrisome thing to do, since I dont have a backup vehicle. The pipe looks a bit rusty and my friend is worried it could be risky, and might not come back together as easily as it came apart.
1st Question: Is it feasible to just cut the bolt and replace it with another minus a couple threads? Are these kinds of bolts common/replaceable. Does this sound like a good idea/bad idea.
2nd Question: If we cant cut the bolt and replace it, what is the best way to proceed? If we have to do it the way I read, would it be possible for you to guide us on where the brackets we would need to loosen would be located. There were no pictures in the post, and the repair manual we have is inadequate.
Hi fry. Garrett. Welcome to the forum. I'm visualizing your dilemma. Since the entire drive train is mounted on rubber mounts, use a long pry bar to shift the engine a little. I've had to do this in the past on other vehicles to remove oil filters.
You might consider using a dremel tool to elongate the hole in the tensioner on one side to allow you to insert and remove the bolt at an angle during that last 1/4". Also, cutting off 1/8" of the bolt will not hurt. You can also remove part of the threads from just one side of the bolt. Tapering the end will leave part of the threads on one side but allow you to tilt the bolt before it is pulled all the way out. Still, I would be very surprised if you couldn't just shift the engine with a pry bay. (Mine is a 4 1/2 foot long steering drag link from an old Ford truck).
