Finding Top Dead Center

Learning how to find TDC on your engine is one of the more fundamental skills to add to your DIY automotive repair arsenal because quite frankly if you cannot find TDC correctly then it is because you do not fully understand how a 4-stroke engine works.

But fear not. A recent Toyota Maintenance YouTube channel episode explains and demonstrates how to find TDC on 4, 6 and 8-cylinder Toyota engines that is necessary to understand if you ever decide to service the timing assembly on your car by replacing an aging timing belt or chain before it breaks.

In the video you will learn:

• How the various Toyota cylinders are numbered
• Where to look for timing marks on the timing assembly
• How to know that you are on the correct stroke of the 4 cycles
• What position the exhaust and intake valves are on the cylinder head at TDC

The value of this video is that it takes out a little of the mystery of finding TDC whenever consulting a Haynes repair or similar automotive manual that instructs you to be sure the engine is at TDC without explaining how to do it and do it correctly the first time.

That said, here is the short video that is a joy to watch and learn from if you are new to engine building.
