First off, 4.7L 1500 QC 4x4.

Doing some much needed maintenance and repairs such as, diff/trans/transfer service, plugs, oil change, and radiator replacement due to seeping seem. I decided remove the radiator, flush the system, replace the thermostat and call it a night leaving install for morning. All was going well until, the lower thermostat bolt seized and snapped leaving half of the bolt in. My question is this; am I correct in identifying this as the timing chain cover? I will attempt to do the 'ol drill/extract/tap method, but who knows how that will turn out.

Any help on identifying the correct name of said part is greatly appreciated. Just in case I need to seek a replacement.

Thank you in advance ladies and gents.

Never mind...answered my own question...ugh!!!

 

I will leave it. It might help a fellow 4.7'er.

 

Good idea weed, thank you.

Btw, extractor bit snapped leaving a nice carbon hardened bit in the bolt. Removing timing cover to take it to a machine shop for extraction.

No idea why, but the portion that snapped off had alot of build up of corrosion causing it to seize and snap.

 

Make sure the bead gasket on the back of the water pump and timing cover are in good shape and no pitting or corrosion that would cause leakage and spread corrosion to the bolts.
