How to: Subaru EJ25 SOHC Timing Belt Replacement

Subaru Timing belt jobs can seem confusing if you have never done them before and often times people will opt to have a shop do it for them. In this video, I will be walking you through how to change the timing components on the Single Overhead Cam EJ20/25 engines. These engines can be found in the Impreza, Outback, Forester, legacy and more.

I would add, be careful removing the 10mm timing cover bolts. If they are tight/corroded, the rivnet thingys in the rear plastic timing cover will break out. The timing cover won't seal well and replacing those rear covers means you have to remove the pulleys to replace the covers.. Really sucks.

Could you do a video on swapping a JDM EJ25 on a similar forester.

@glorentzen says:

I don't have a subaru yet, but your channel has me prepared to do it all when I do.

@cascadianrallyteam9023 says:

Did it have green coolant in it to start with?

@dkleinsch823 says:

Installed this very kit before. Great quality. Very easy job!

Another useful contribution to the community. You’re a legend bro

@roybrown7717 says:

can you do a timing chain? i belive FAs use them

@bullnukeoldman3794 says:

The first thing I did was install the Aisin timing kit on my 2010 Outback 6MT (with 96k miles but 11 years on the original belt/idlers/tensioner) right after I bought it. Super easy to accomplish, much easier that a '92 Mitsubishi I'd done some years back. I did goof it a bit as I found out later. The cam belt on manual tranny EJ253s has a belt guide that must be properly adjusted to prevent timing jump if the engine hard stalls on a bad shift. When I pulled the engine for other work a couple years later I found a deep groove in the cam belt – I'd adjusted that belt guide too tight and it was eating into the cam belt. Installed a new Mitsuboshi belt, properly adjusted the belt guide, good to go.

Aisin is the Subi mechanic secret lol, Gates is cool too, but watch out for the water pump, or get it w/out the water pump, and get an aisin water pump (rockauto).

I just did this on my 03 legacy and its such a easy job. But the loaded drivers side has almost no room for "movement". But i used a breaker bar to make sure it did not spring out on me

@alimodeste says:

HEY Smeedia, can you please give me a link to purchase an overhauling /rebuild kit for my SF5 ENG. ENG code SFR113663. THANKS

@WholeCosmos says:

glad to see you giving a regular ol subie some love

@patricktoms9391 says:

i recently picked up a sohc and thinking on doing head gaskets to it. its my first Subaru engine that I've token apart

@KoryBrooks says:

A SOHC Subaru was one of the very first timing belt replacements I done starting out as a mechanic 10 years ago. Was an 01 legacy outback.

@jjoop says:

I try to do valve adjustment when im in there too

@RandalFuentes-yl8nv says:

I wanna do this on my 06 LGT, I haven't seen a video on the DOHC and I'm scared of messing up the timing, any recommendations?

@conqueeftador2808 says:

When are you gonna restock your store my ex stole my smeedia hoodie and I need another

@bradgreen987 says:

Nice tutorial. Why did they go to chains on the FA motors? I heard they can stretch like the belts

@stunadracingteam5909 says:

I have a 2013 wrx with 60k miles when should I have it done?

@seanmchenry4187 says:

Why not do the head gaskets while you're in there since those motors are known to blow them more than others.
