2012 Prius V 1.8l timing chain replacement

This video shows you how to set the timing chain intake and exhaust cam gears along with the crankshaft. A future video will show them when they are set correctly.

To set timing chain, the exhaust sprocket, one nearest the fire wall, you will find a rectangle punched into the sprocket if it still original there will be a little blue spray paint found there. That mark is lined up with the chain. The intake sprocket, side closest to the radiator, you will find there are two groves, choose the grove to align with that has a dot on the face. Of course line the lowest part of the chain lines up with the dot on the crank sprocket gear. Important: Once all marks are lined up place the rear timing chain guide in place and wire it up to the upper timing chain on top so that the rear timing chain guide has tension on it so keep the timing chain from jumping a tooth when placing the timing chain cover in place. It has a tendency to jump a tooth on the lower crank sprocket if this is not done. Recheck your marks before bolting on the timing cover. Once cover is bolted on..then remove the wire you put in place earlier. Load the tensioner and insert and bolt it in place. Turn engine counter clock wise till you hear a click. Check by poking a screw driver against the rear of timing chain to see if slop in timing chain is gone. Have a good day!

Do you have to take the head off for the timing chain? I'm just about to get started on mine. It's a 2014. What manual did you use to help you?

I know this comment is 8 moths old, so potentially less for you and more for anyone else who may be curious if they cross this question: You wont need to remove the cylinder head to do the timing chain :)

What happened in the end???

[@ccobra6813]

That is a horrendous amount of sealant coming out of the cover. That stuff comes loose inside the cover and plugs up oil ports.

How many miles was on your Prius when you decided to change the timing chain? I’m asking because I want to know when to change mine.

[@AdamDeVries]

I only removed the timing chain because I had to change the head gasket. The head gaskets seem to blow at about 180k miles on the gen 3 Prius

Chain don’t fail right

@@SIMPLEGUY423 mine seems fine I'm re-using 250k miles.

i am sure if he started the engine with bad timing his valves are destroyed

[@leeroypana7920]

bad video shooting. I even cannot see the location of the timing chain box relative to the engine
