What have you found or fabricated to tighten the 13 ATF hex nut on 914-6 heat exchanger passenger side? I think that's cylinder number 1.
I'm sure this is probably mechanics 101, but I'm having a hard time with it. I've tried every combination of 1/4 socket, u-joint, wobble extender, flex driver I can find. No room for a box or open end wrench as 2 sides are blocked by bracket and pipe. Nothing I've tried provides enough engagement to properly tighten it.  |

The support strap needs the hole slotted so it can move away , If you insist on a 13mm hex.. and your studs short..
