I notice upon installation of the 3rd generation secondary tensioners that the right and left are not mirror images of each other.

At first I was concerned that the wrong part(s) were in the boxes. After the install I assumed that the new design just had the right and left tensioners designed differently from each other.

I just want to make sure before reassembling and start up.

The Driver's / Left side has the broader plastic surface area to the top and is spring-loaded at the top:



The Passenger's / Right side has the broader plastic surface at the bottom and is spring-loaded at the bottom:



Has anyone else noticed this?

Also, I do not know how anybody "primes" these tensioners with oil prior or after installation. Comments here?

Thanks.

 

They are correct.

To prime them with oil you must remove the fuel injection (not fuel pump) relay and crank the engine for about 5-10 seconds.

 

I used a syringe and injected the oil into the tensioner before installing them.

OK, so it's not the fuel pump relay (No. 4 in trunk of NA cars)?

So where is the fuel injector relay located and identified?

Thanks
