I need sequential diagrams, pictures, video, images, drawings. I learn through my eyes viewing the procedure, rather than just words.
A step-by-step procedure on what tools to use on what parts, first to remove to get to the head gasket and so on, with diagrams, pictures, so I know that it's the same car as mine. I can't afford to take my car to a mechanic. Can someone out there help me, please?
Do you
have the same problem?

NOTE:
Use fender covers to avoid damaging painted surfaces.
To avoid damage, unplug the wiring connectors carefully while holding the connector portion.
To avoid damaging the cylinder head, wait until the engine coolant temperature drops below 100 F (38 C) before loosening the cylinder head bolts.
Mark all wiring and hoses to avoid misconnection. Also, be sure that they do not contact other wiring or hoses, or interfere with other parts.

1. Make sure you have the anti-theft code for the radio, then write down the frequencies for the radio's preset buttons.

3. Install the dowel pins (C) and new cylinder head gaskets (D).
4. Clean the timing belt drive pulley.

See picture 14

5. Set the timing belt drive pulley to Top Dead Center (TDC) by aligning the TDC mark (A) on the tooth of the timing belt drive pulley with the pointer (B) on the oil pump.

See picture 15

See picture 16

6. Clean the camshaft pulleys. Set the camshaft pulleys to TDC by aligning the TDC marks (A) on the camshaft pulleys with the pointers (B) on the back covers.
7. Apply clean engine oil to the threads and flanges of the cylinder head bolts.

See picture 17

8. Tighten the cylinder head bolts sequentially in three steps.

NOTE: Perform each step twice.

1st step torque: 39 Nm (4.0 kgf-m, 29 ft. Lbs.)
2nd step torque: 69 Nm (7.0 kgf-m, 51 ft. Lbs.)
3rd seep torque: 98.1 Nm (10.0 kgf-m, 72.3 ft. Lbs.)
Use a beam-type torque wrench. When using a preset-type torque wrench, be sure to tighten slowly and not to overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt, and retighten it from the 1st step.
9. Install the timing belt.
10. Adjust the valve clearance.
11. Install the cylinder head cover.
12. Install the exhaust manifold and tighten the nuts in a crisscross pattern in two or three steps, beginning with the inner nut. Always use new exhaust manifold gasket.

I appreciate your efforts. I am 64 years old, a veteran and most of my life I've been a white collar worker. I worked on my cars before, so I know my way around the tools and parts. I'm having trouble putting the diagrams in the right order which I'm not sure if this, is in the right order from getting all the tools, parts and materials needed to do the work, beginning to end. I guess I'm asking again for help but it might be better if I follow a video instead of looking at diagrams, so I can hear the person say what order, the parts that comes off the car, first, second, etc. And I can see the person actually doing the work, so it gets done right with no problems after everything gets put back together. I am doing this all by myself because no one wants to help me. I asked several people, but they are too busy. I'm on my own, I hope that's enough to get the job done. Thank you for answering my first question.

I am having trouble with removing the number six head bolt. I have the others loosen, but can't get the last one loosen. Now the head of the bolt is partially rounded and I can't get a good grip on it to remove. I admit, that it was very difficult for a first timer, taking all the different parts off the car with little knowledge and not all the right tools. I don't want to call defeat. Especially after this past week. I took my wallet out at an AutoZone store, I was so over whelmed with this bolt issue that I did not notice at the time when I paid for a tool that the person behind me in line did not have anything in his hands to purchase when another register opened but he stayed behind me. I have never been in this particular AutoZone store before, so I went home, rested awhile and decided to go to a different auto store for the same tool but did not have my wallet. I lost all my money, which was about $500.00. That was my car money. I know you didn't ask, but I want you to know how I am feeling about this situation I am having. I don't think that I am capable of finishing my car and I need a car to drive. I have to drive I need to drive, that's all I have is my car and to drive. So, I am asking again for some help, please. I hope you can. Thank you again for answering my first question, I really appreciate it very much.

Wow! I'm really sorry to hear that. Does AutoZone have cameras set up so you could at least notify the police and provide a picture?

As far as the bolt, can you upload a picture so I can see how bad it is? Also, please take a picture of the socket you have been using. They may 12 point and 6 point sockets. A 6 point is much less likely to strip the bolt. If I can see the bolt, I can try to determine what you will need to use to remove the bolt. They also make sockets to remove stripped bolts.

If you can, send the pictures I requested.

Thank you for answering my question. I really appreciate it. But I no longer need the bolt removed, it took myself and two other guys to get it off. I know that this was going to be an impossible job to do by myself but I had no choice because I had no one else to help me. And thank you for asking about my situation, yes I called the police and someone came to the house. I asked him if he would be able to go and look at their video and he said that they even have trouble with businesses getting their cooperation in letting them view the video footage. So my wallet is most likely a lost and for me to just let it go. If you don't mind helping me out just one more time, it would be greatly appreciated. I'm still having trouble getting the head off. The last part I took off was the exhaust and separated it from the muffler. And still don't know why I can't remove it. What am I doing wrong or what did I miss taking off? I am at my wits end(desperate). I need a step by step from this point on, how to remove the head on a 2002 Acura tl 3.2L? Help me, please.

Welcome back:

I'm sorry to hear that. One would think you would get more cooperation. Ugh! Society has sure changed.

As far as the head, if you have the exhaust manifold removed, the timing belt, and all head bolts, there shouldn't be anything else holding it. Is it possible for you to upload a picture of what you are looking at? I may see something you missed.

Let me know.
