Does anybody know what socket it takes to remove the harmonic balancer, so I can get to the water pump bolt. This is a 2001 Chevy Silverado 2500HD, 2WD, 6.6 duramax diesel.:help

It should be a 36mm 12 point socket there is a special tool you can buy from the parts store to hold the flywheel from turning and it comes with the socket.

X2 on that. if you get get it in there. but you will have to USE A 3/4" DRIVE breaker bar to get her loose if you cant get the gun in there. i couldnt get the gun in there unless i took the radiator out and the intercooler.

Really? What kind of impact and socket did you have? I pulled the radiator and my Ingersol fit fine with a Snap-On socket.

You guys like making extra work for yourselves!Put a socket with a breaker bar against fram rail, click key and "POP" bolt comes loose. An old timing belt trick.

I'd go with getting the socket (borrow or buy) with the flywheel lock tool. Keep radiator in place and use a breaker bar with a 3' pipe over bar to add length... it comes off easy with this setup. Just pull the dampner off by hand... No puller needed; maybe giving a light pry to get it started. If you try the bar on frame w/starter; disconnect your wire harness to injectors or pull ecm fuse so it doesn't start or things could get even more interesting:)

IGN 1 is the fuse you need to pull to keep the engine from firing.

You can make your own hold too by using a socket and extension if needed. Simply remove the starter and put a 15mm deepwell over one of the torque converter bolts (you may need to spin the engine to get one to line up) if the socket you are using is not long enough then add an extension and viola you have a flywheel hold tool.

I never had to pull a fuse. Just a quick click of the starter. Usually on second click. But if it re-assures you

Once your in there. Take a torch and heat the middle of the bolt. Once its red hot he bolt will come right loose. When going back together get it tight and heat it again and tighten it somemore. Works great and no you will not hurt anything with the heat.

Except the tensil strength of the bolt and possibly the balancer itself if your not careful.

Thanks for the fuse info...

I really like the flywheel tool that comes with the socket.
Leave the starter in... leave the radiator in... break the bolt loose with out torch and tighten bolt properly. If you break the bolt loose with the motor how do you get it tight again? Turn the motor over backwards?...Last time I tried to hit a bar and socket setup with a big hammer it didn't go so well.

I just take the radiator and intercooler out and use a impact it doesn't take that much longer and that way you have more room to work

The flywheel lock tool is so slick... once you use it and a breaker bar on the dampner you would never want to do it any other way. Saves enough time to pay for itself.

all you have to do is reverse the polarity on the starte and the motor will turn backwards, duh.

The flywheel hold tool is nice. Only PITA about it is removing the starter.

Removing the Radiator stack will also make your life easier and doesnt take but maybe 30 minutes. It will save time on the rest of the job.

You don't pull the starter to use flywheel tool...Just slips into the hole on the bottom of the tranny after popping out spring steel cover. I can lock up the motor in 10 seconds.
Leave the starter in and leaving the radiator in saves about 1.5 hrs. There is plenty of room to work between the motor and radiator with the shroud and fan out of the way. Just how I roll... Thats 1.5 hrs I get to do or bill something else.
