Oil cooler line time..... Opinion?

bk95td said:
The 45 degree hose ends are a much better way to go than trying to get the 45 degree fittings at the right angle to get the hoses hooked up. I wrecked a cooler trying to get the fitting lined up. Then there is the part of if it's tight enough to not leak if in that position. Are you listening Greg and Leroy?

:thumbsup:
 
I am:bigear:

Also, at the beginning of the post someone asked why the lines are not sold seperately. Someone else replied correctly that it is because they are different than what the stock cooler can use.
If you have the oversized cooler and just need hoses and fitting I will sell them alone.

Believe he is suggesting that the hose with a 45 end on it would better than the 45 adapter??

Yes, you are so correct! You pretty much have to use 90's in the block, but you can usually crank those down enough to make them point in the right way. Not so with a fragile oil cooler.

In the block would you choose over tight or under tight if it came down to the imperfect final orientation?

Well, you don't want to over do it, but probably tighter. If they are too loose, they are going to leak. I first might try swapping the fittings and see if they fit better. You can crack the block or break off the fitting in the block, but it takes a bit. Plus, you have a little wiggle room with the orientation, you just need the hoses to connect without hitting anything. I guess use common sense, of it feels like you are going to break something, you probably are. On some other applications, I have ground down a tap and made the threads a little bigger (they taper), but that was on a block out of the car. Probably wouldn't do that with the engine in the truck. I guess in the end if they are really off, I would get another fitting and try it. The fittings are available in steel & aluminum so I would think you could find something that would work in the end. FYI, my Hummer GEP engine came with a 90 degree steel AN fitting for one of the oil cooler lines, so I'm guessing they just tighten them as needed to point the right way at the factory.
 
If you can't get it another turn cause it feels too tight I would take it out and reseal the threads and start over. It doesn't need to be real tight, just snug, it's only at 60 psi max.

Thanks Matt for helping me find this thread again.

This is the only way I can come up with a 45* swivle. I could add a 45* fitting, it has male jic/flare to female swivle jic/flare. It is the only way I have found so far and still be a relitively clean install.
You would use a straight pipe to male jic/flare fitting on the cooler. Attach the 45* fitting discribed above to the hose. Hose has female jic/flare so male end of fitting go's in hose. That give you a 45* female swivle that would attach to the straight fitting in the cooler.
Confused yet?
Bad news is each fitting is $14 so $28 additional price on the cooler kit.
If anyone would like this configuration just let me know.

A bit of a bump here.

I finally got around to installing my lines I'd purchased months ago. Other than a bit of grinding on the exhaust flange, there were no surprises...on the install.

The replacement factory lines that came out were a bit of a surprise. One of the lines was off angle to the flow and looked like it was about to come off!

Whatever you do, pull you factory lines and replace them. Burning Oil, thanks for making these kits available. Yeah, I could have gone to the trouble of assembling all the fittings myself and...wait, no I couldn't.

Again, thanks.
 
I thought I had posted pics of the oil coolerwith leroy's swivel fittings. Guess I didn't. The swivel fittings work great:thumbsup::thumbsup: Tons of adjustability without worry of breaking the cooler. Well worth the extra $.

My single issue was grinding the exhaust flange to provide a little relief. Otherwise, it went in easy. I can't describe how enthused I am to know that my lines are finally reliable and, in my case, not likely to fail. I wish I'd taken a picture of the factory line I'd installed not that long ago that was leaking at both ends with one looking all the world like it was ready to separate.

Have not heard of anyone needing to relief the manifold?? What was the problem? Also, I see in your signature you got the kit from another vendor??
Sorry I cannot remember, did you actualy get it from me?
Either way glad you are fixed up.
Thanks barry for posting the pictures of the swivles. They are now available if wanted.
 
Buying a complete kit does make it easy, but there is really no reason you cannot source everything you need to install new lines. Here are some pictures of my new oil cooler setup.

It looks like Barry used straight hose ends with an extra 45 degree adapter. I used 45 degree hose ends. That eliminates one of the connections and saves a bit of space. However, take your checkbook with you when you buy the angled hose ends!
 
To alot of people such as myself, it would take me DAYS and alot of running back and forth just to get all the parts. I would have to make a few oily trips for sure, and to boot, hydraulic stores aren't open on weekends when I could squeeze this job in. So thanks LEROY for offering the kits.

BK95, leak free on the swivels? :)

Leroy, how much extra is the swivel kit?

BobbieMartin, should relocate that horn! Look at all the cooling fins she's blocking!
 
The pics are from the 94"599 Project" truck. It hasn't been run yet but has been primed and no leaks:thumbsup:.Pretty shure it won't leak when hot. Without the swivels I've had leaks.:eek: That's how I broke a cooler was getting another turn on the 45 degree fitting when the wrench slipped off the nut on the cooler:mad2::mad2::mad2:. Ripped the cooler right apart

A friend of mine is an Earl's distributor, so that makes it easy for me :smile5:

BTW, the truck cools fine, even with the horn in the way. Maybe its the additional airflow from the WT grille! ):h

I always wondered why GM put one horn there and the other behind the LH battery :confused:
