1. Does it matter which hard line goes into which plug in the Oil Coolers? My assumption is the outer plugs go to the engine (Passenger side to the engine, drivers side to the oil filter). Is this correct?

2. How do you properly disconnect the hard line that is connected to the bottom right hand part of the engine? It appears to be a 21mm bolt, but I want to verify this is right. ( I don't have a 21mm wrench )

 

#2 I figured out on my own.

But back to #1. Can anyone explain which pipe goes into which plug in the OCs? THe attached document doesn't make it explicit and I want to do this right.

Anyone?

 

Your assumption is correct. The front cover line attaches to the passenger side oil cooler and the driver side cooler attaches to the line coming from the oil pedestal.

 

Just so I am 100% clear and anyone who searches on this same question is, does the below diagram of my assumptions on how this should link up look correct?

If a connection is reveresed will it matter?

 

it's 23mm. don't buy the wrong wrench!

 

^ yup. Now does anyone know if the oil cooler plugs are interchangable, or is my diagram correct?

 

OK I found this from Howard Coleman's Dual Oil Cooler Cheap Thread:

Thank You WAN for this graphic. I am reposting Just in case another newcomer is searching for this.
