Hello and welcome to Just Answer!
Yes, the engine must be removed to access the rear timing chain. Some of the components will be located behind the transmission bell housing so the engine must be removed. If you are just wanting to change the hydraulic tensioner, that can be replaced without removing the engine.
Is this a commen problem with the engine with ford and can you send me some digram what the tensioner is located. I have a mechant book for this car but pictures aren't to clear.
Yes, timing chain problems are VERY common on this engine. Usually it's the plastic guides that break. If you find any broken guides, you may need to pull the oil pan to get all the pieces out. Let me see what kind of diagrams I can come up with. One moment
Here is the right side tensioner. located on the right rear cylinder head. It looks like a bolt from the outside. It just screws out like a bolt.
I'm working on more diagrams. one memoent
Here is a photo of the rear camshaft sprocket and chain. The lowwer part of the chain cannot be seen as it's inside the cylinder head and block.
There are lots of special tools needed to properly time this engine. I recommend checking your local auto parts store to see if they have have a ford master cam tools set that you could rent. Otherwise you are going to run the risk of improper timing. Due to the amount of work that is involved in this job, I recommend you do everything you can to get it right the first time.
Are there any specific questions about this job that you have?
At this point I'm somewhat unclear on exactly what information you are looking for
So by removing the tenisor would it get out of time.
no it will not as long as you do not rotate the engine.
for engine assembly purposes there is a special "dummy" tensioner that is included in the master timing tool kit that goes inplace of the tensioner while assembling so the engine can be rotated during assembly. But if you are just going to replace the tensioner, as long as you don't move the engine with it out, you will be fine.
Okay Ill try the tenisor,Is there some better picture to see how this is place+
Here is a photo of the rear tensioner. The location pic above is the best one i have. It's located on the right cylinder head all the way in the back. You can't miss it because of the large hex head. It looks like a really big bolt head sticking out of the side of the head.
You could probably see it best looking through the right wheel well.
Thank you very much for your input. Now Ill have some work to do Thank you
Your welcome. Have a good day!
