!!!help!!! Timing Marks For 2002 Ford Explorer

[balonez23]

!!HELP~! Timing Marks for 2002 Ford Explorer Aloha!
Does anyone know the timing marks for a 2002 Ford Explorer XLT. My mechanic is puzzled. He replaced 3 of the front timing chains, checked the the 4th one which is located in the back of the engine (he said the design of the engine is a POOR design) and when he put everything back together, it started and died off. He couldn't get it to start up again. To do so, he's going to have to take EVERYTHING OFF again and check the timing again. He said the headache part about it is that there are no timing marks. He told me that if it's even slightly off; the engine won't turn. He even compressed it and checked EVERYTHING else on my car like battery, spark plugs, he even made sure that the valves weren't damaged.
He's had my car going on the 4th week and I really need to get back so I can go to work. I'm catching the bus right now and running a bill up on labor costs.
Any help is appreciated!!!! Does anyone have a solution on how to ensure that my chains, cams (???), etc. are on correctly? I'm not too smart about cars. Please let me know. I am DESPERATE!!!

I don't know the answer but the ones here that do will need to know if it is a V6 or V8. A Haynes manual should show this information.

It's a V6. Thank you, thank you, thank you for any help you can provide!!!!

from what my hanes manual states there are timing marks.
set the crank on tdc with keyway up,then install a special crank holding tool. install the camshft holding tool on the rear of the left cam(the cam has an alignment mark on it and so does the tool) line up the timing marks and tighten tool to hold cam in position. the right cam holding tool goes on the front of the cam, also has the timing marks on it. seems very simple with the tools.

also you must have a 4x4, the reason i say this is there are only 2 chains in the front of the motor for 2 wheel drive , and 3 chains in front for the 4x4 model

4 weeks for timing chain replacement, time to find a new mechanic. There is a special tool that fits on the end of the cam. Sears sells the whole kit of "special tools" for this type engine including the timing tools. Any decent mechanic with proper manuals should have known this.
