How could anyone down-vote this video? It's a good diy video. No doubt this guy comes from more of an engineering backround unlike your typical auto mechanic, but that's why this video is so thorough and disciplined....just like an engineer.
I wonder about these one time bolts.Looks like a good way to keep selling more bolts.Did any body make a video testing these bolts. How many times can you safely use them.why not use everlasting bolts. Would make a nice video to test this. I would bet you could torque up to spec50 times.
David, that is a great question, and I had the same thought. However, these bolts are made to stretch when they are torqued, thus the one-time use. Could they be used again? That is a question for a metallurgist, but my recommendation is to just replace the bolt. What would the cost be if it broke? Probably more than would be worth it. But, if you get more details, please let us know!
Hello, I want to do the same work. You didn't say or show how did you take off the front part of the car. Must I open the houses of airconditioning coolant system in the front? How did you do that? Do you have a machine for filling it? Thank you very much. Lubos
I can give you a step by step on removing the front of the car to prepare it for service. Contact me through the website at theamericangarage.us and I will give you more detailed info.
That is a good question- let me see if I can expand a little- Belts may be slightly different sizes and they do stretch, so to get the timing absolutely perfect, the cam shafts have to be put in the correct position first, then the gears set into place according to the belt. If you put it together with the gears loose, then you can get the belt installed and tensioned properly without moving the cams by accident. Then, with the cams exactly right, and the tension on the belt exactly right, then when you tighten down the gears, the teeth will line up perfectly, and you will have a more perfect timing. Does that help clarify?
I'm sure this engine exploded after turning it over.... the timing is totally wrong and moving the cams at TDC equals a valve job for sure. Big holes in the cams need to be facing inwards not outward. If for some reason your timing marks don't match up just put the crank at TDC and turn it back 30* before TDC at this point u can turn ur cams without worry hitting anything inside and line up everything but to be 100% sure just remove the valve covers and u should see the marks on each cam where the cam chain tensioner is located.
Now that would be true, and the engine would have blown up if I had turned the camshafts AFTER I had taken the belt out. You see, it does not make a difference whether the big holes are on the inside or the outside, whether you make your own bracket like me or buy the tool. What matters is that the timing is kept in the exact location, whether it is TDC or BDC, and in sync with the main crank. Don't turn the engine over after you remove the belt! The car ran nicely for me for 70,000 more miles before I sold it with 280,000 miles on it. Plus, I did other shows with the car after this one, so obviously it did not blow up. It is a good idea to take of the valve covers, which I did on another show, to look at the positions and replace gaskets. However, it is easier to remove the spark plug and find TDC or BDC BEFORE you remove anything- thus you will not have to worry about the position of the valves. TDC or BDC will result in the holes being horizontal- with big in or out. Then you can start removing stuff with no fear. Look for a new episode where I did this again on an Audi A8.
I agree with Angel C. The camshafts should be lined up with the flat part facing each other on the inside , thus making the arms with the big holes facing each other as well, on the inside. I agree with valve job. Probably bent valves from striking the pistons. I have made my own alignment tool , It’s not rocket science. A piece of 3/8 aluminum 26 “ long , can be longer , cut 3” wide. Find center of your aluminum strip and work from there .Aligning with the center part of the crank end.the center ,working your way out , allowing for bends. It’s a lot of precise measuring. I made mine to use , even with the water pump pulley on. Bolts same size as holes in the arms bolted to the aluminum made plate, or alignment tool. Thinking outside the box helps. Good luck.
Lubos, you do NOT have to open the A/C system to get at everything. CAREFULLY unbolt the A/C condenser from where it is held in place and then oh so gently swing it to the side without loosening the hoses. You can do this any time you need to get in there.
didn't anyone notice his cam timing is off?.. The larger holes should be facing inwards. He made his own cam locking tool, he might have caught it if he bought a tool.
Very perceptive Doug. However, you can do it either way. Yes, the position is different, but the timing is spot on. The car drove beautifully for the next 70,000 miles and is still going strong. And yes, I did make my own tool
Yes the timing is totally wrong and he was moving the cam while the crankshaft was at TDC and that's a no go!!! If you want to move the cams u need to set the crankshaft 30* before TDC at this point u can spin the cams without hitting anything inside the engine.... people should learn from this video on how NOT to this job.
Great video . I currently work For audi of America 6+ year Service technician and even in the dealer life we make our own special tools .. some people need to do there Home work before commenting lol
Just watched this. This timing tutorial is simply incorrect. UA-camrs please beware of individuals professing to be experts when clearly they unintentionally causing serious damage to your car's engine. Here's why. Firstly this guy doesn't understand the design and mechanics of this engine. It's a German design not American. The index cylinder is no 3 not 1. He has no proper understanding of the intake and compression stroke. He is setting the timing here on the intake stroke instead of the compression stroke. As you can see by the incorrect setup of his tool. In the intake stroke the intake valve is always slightly open. He foolishly thinks he's on the compression stroke and proceeds to put the camshaft in rest position and in so doing closing the valve. Result, the valve will open later than it should in the combustion cycle and thus take in lesser air than it should as the piston is already close to the end of the intake stroke. To His will cause serious long term damage to the engine: soot and carbon build up due to an overly rich mixture, low power, emissions failure, poor starting, high fuel usage, overheating, damaged cats, misfire, Etc. The larger holes should be on the inner side of the tool when locked in position. The sprocket plated should also be slightly off centre and not perfectly level. Thus guy should stick to simple American Chevy motors. This poor engine is being starved of fresh clean air. This is the danger of UA-cam. Young and naive upstarts following these guys and messing up their vehicles. Leave it to trained and qualified certified technicians please.
Thank you for your astute observation. I'm watching and recording as many vids before I undertake my own timing belt replacement, I too noticed this oversight, scary results are in order if not correct.
@@billpfeffer6954 my pleasure. please revert if you need any help. the reward of correct timing is the joy of a perfectly running engine and the satisfaction of having done it yourself.

He doesn't know the difference between horizontal and vertical. Review the video and see for yourself. An engineer would never make that mistake.

Nice
Thank you! This helped me so much with my S4!
Didn't show setting tensioner. Why not just use a crank lock tool?
Great vid. Thanx for this!

Do you have a vid on how to get the front of the car off please ???? thank you
Sorry, I sold the car. But perhaps I can put together a step by step for you. Check back later.
why do I have to loosen the 2 cam shaft gears? It seems like the belt should go on with out that step.

I spotted the same thing, the big holes face inward not outward.

Have you opend AC houses at all?

I would of changed tbe water pump with it all apart

What Year ??????????
2001
This was a 2001 A6
My timing is not right on my Audi a6 2.7 quattro
How did you go about fixing it?
