I'm using @mrblaine's nearly bolt on hydro assist and had a few questions.

The first is the adapter that screws into the ends doesn't seem to go all the way in (is this normal?),

the second question is what are the small rectangular brackets that look like they should be part of the cooler holder be used for?

sorry for my ignorance, just trying to visualize how the pieces go together before trying to install it.

Those adapters do not go all the way in. Screw them in until they are snug. Make sure to use red locite on the threads into the cooler otherwise they will leak!

As for the brackets, see here:

The bracket slides in between the cooler and the backing plate. It captures the v-bar between it.

Then you insert the stud plate from the back of the bracket and put the bolts on the end like so:

Make sense?

@Chris - is red loctite needed on all threaded connections in the system, or only at the reservoir & cooler?

  • All fittings with threads either straight or tapered get red liquid Loctite at the following locations:
    • -8 return adapters into each end of the cooler. Just the adapter, not the push lock fitting that goes into the hose.
    • -12 male into the reservoir for the feed hose to the pump. It is O-ring Boss or straight threads with an o-ring. It will seep fluid and back out when you try to remove the flare fitting from it if you don't use red Loctite on it.
    • -8 male return from cooler same thing. ORB, will seep and loosen without red Loctite.
Does that make sense?

Only at the cooler and the reservoir in other words.
 
Yes, to paraphrase it is only the male end of adapters that require red loctite
 
I don't know if it was me or if I was doing something wrong but I couldn't get those rectangular brackets on without cutting "slots" into them and sliding from the center-out. Is the trick to push the radiator/condenser way back to insert the bolt plate through the entire assembly? Even with the "slots" in the rectangular plate, it's held in place and it's not going anywhere...
 
@Chris - How did you go about routing the hydraulic lines to the cooler? I was looking through your build thread and noticed that both ends had a 90 degree fitting that were going down.

My plan was to run the return for the steering box to the left (passenger side) of the cooler then out the right side (driver) and to the reservoir. How do you do this since it looks like both lines go down below the grill.

Thanks,

The line on the passenger side goes down, under the bottom of the cooler, and then up the the reservoir.

The line on the drivers side goes straight down to the steering gearbox.

Not to hijack, but do you have Blaine's kit? I ran the 45 deg. JIC fitting out of Blaine's brazed custom fitting attached to the gearbox. It pretty much points the JIC fitting upright into the grille towards the drivers side connection of the cooler. Passenger side fit into the bottom shell of the grille then into the drivers side of the engine compartment to the reservoir.

The condenser and radiator needs to be pushed back. If they needed slots to install they would come with them.

Yes I'm using blaines kit, see original post

You 'tards and not knowing which is left and which is right. There is no driver or passenger since the TJ is offered in both right hand drive and left hand drive. There is only left and right. If you don't know which is which, sit in the driver's seat. Flip the lever on the turn signal to indicate a left turn. Now get out of the vehicle and walk to the front or rear and see which side has the little blinking fucking light. That is the left side. If you can't figure out that the other side is the right side, get back in the driver's seat and flip the lever for a right turn and repeat the identification process.

The cooler line routing-

From the return port on the steering gear it goes into the adapter fitting and a 45. The 45 points the line between the lower part of the grill and the condenser. From there the line runs across the bottom of the grill and then a sweeping bend up to a 90 screwed onto the adapter in the right side of the cooler. The 90 points down.

The left side has the adapter, then a 90 pointed down and the line exits the grill area right near where the first line from the steering gear return goes in. From the grill it runs up to the return port on the reservoir.

That would help more if we know the line goes down from what?

That makes more since, thanks for the help.
