Im working on a 2011 F150 4x4 Lariot with the 3.5L ecoboost

 

I didn’t think A 2011 3.5 eco F-150 has an internal water pump. What did you change?

 

part #-7. there is an impeller behind that gear that pulls coolant through. That sprocket gear is what snapped, in turn throwing the timing chain out of whack, in turn, damaging the valves. My problem isnt the water-pump though, My problem is it wont start. Does it need to have piston #1 at TDC compression stroke prior to setting everything to the timing marks?

 

Sorry you're having trouble on that particular job especially. I would defer to the manual on that one. Or, the next best thing would be if DNADan seen this thread. If you had heads, and other things done to your truck due to the failure, you have more than a few variables introduced here. I hope you get this sorted out, and report back with what happens for the benefit of others later.

 

Thank you, I certainly will. Thanks for taking the time to read through it. Your right, there are multiple variables, but im just asking for a simple Yes or No right now. And that is to the question " does the #1 piston have to be set at Top Dead Center - On the compression stroke- before i set the phasers, and the timing chain to all of the timing indicator marks? If i could know that for sure it would eliminate alot of the variables.

 

I have not done the repair myself. I'd still be trying to see if I could find a clip of the service manual for this one.

 

I’ve never done an ecoboost. But in the old school cars yes TDC. Compression stroke doesn’t matter as that’s got to do with the cam timing being aligned correctly to the crank. That’s were the timing indicators are super important.

 

That right there. I always thought there were places for things to line up on this. The info might be right there with where you got all the torque specs for these jobs.

 

When I did my timing chain I turned the crank until I had the dots all in position, then I simply took it off and put the new one on the same way. If the crank is out of phase with the cams, I don't know what you have to do to get that back in agreement. I can look in the service manual I have, but I think this get's into the engine building aspects which the service manual does not cover. RMBRyan or an engine builder is probably the best person to help you. You need to be careful because these are interference motors with a fairly high degree of precision. So if something isn't in sync, you could slam the valves and ruin the motor.

 

thank you, I guess because i recently timed my 95 f150 with a distributor that i was hoping that it would still have some basic fundamentals that needed to be carried out. I still feel that there should be a procedure for timing the engine when the heads are removed, and put back. This seems like it would be something done with some frequency.

 

Here is the entire assembly section of the service manual for my 2012 3.5L Eco. This is the original dated procedure, so not sure if anything has changed.
As usual, please use this at your own risk. I don't take any responsibility for how you use this information.

 

This is exactly what i needed. Thank you so much. It is a little involved, but if i would have had this from the begining my truck would be running right now. Im sure this wasnt free from Ford was it?

 

It's from a $20 service manual on DVD from ebay. Probably a knock off of the real deal. Glad I could help!
