Can anyone tell me the ID of the stock rubber sections of the oil cooler lines?

Im doing my own custom cooler setup but im shying away from the traditional AN fittings and braided line setup. Ive got other resources on hand that are very high quality and cheaper (not nearly as pretty tho)... However I do need to know the line ID to get my fittings squared away.

the steel part of the oil cooler lines is approx .33 inch I D. I assume the rubber lines are similar. i just finished adapting an OEM left side cooler to the right side and used dash 8 lines which are .44. i looked around for something other than stainless braided lines too as it is overkill and a pain to fixture so as the lines don't saw thru things over time... i ended up using them.

That sounds a fair bit smaller than they look from the outside, but thank you.

Hydraulic hose is the perfect hose for this IMO, its cheap will easily take the temperature and pressure and its compatible with oil. The fittings shouldnt be a problem either... Im figureing about 1/4 the cost of AN setup.

do you know the size of the fittings (thread, pitch, etc) to connect the second oil cooler?

i plan to do a "how to" on this for the archives after i fire up my motor but here's the deal in short form...


how to add R1 oil coolers to your non R1 for $180.

acquire a non R1 FD oilcooler. there are tons floating around fro wrecked/parted-out FDs. i got my cooler for zero dollars.

it is important that you get the cooler, duct, the two oil cooler rubber-alum washers for the oil in and ouput fittings, the rubber mounting grommets.

straighten the fins of both coolers while you are watching the Speed channel. i used a small rectangular pick. an easy 1 hour job that turns out surprisingly well.


purchase

3 male 22mm X 1.5 to 8 AN adapter fittings $18.99 (coolers) Pegasus.com
1 male 18mm X 1.5 to 8 AN adapter fitting $13.99 (engine)
2 45 degree 8 AN hose fittings $14.99 ea
1 straight 8 AN hose end $6.49
10 ft #8 stainless steel braided hose $54.90

total $148

medium mesh stainless steel (screen) #6 X .035 wire (so you don't have to straighten fins again)

5/8 I D clear plastic hose 6 ft cut into sections, split and cover SS hose in areas where it might wear against various contact points.

do not forget that the 4 adapters require washers to seal!!!!

use the aluminum/rubber OEM washers at the 3 oil cooler ports and the OEM washer at the motor.

you will need to refixture the duct so as to fit the pass side. mine was easy and turned out really nice. ditto the three mounts for the cooler. all the R1 studs and holes are on non R1 chassis which makes it easier. the job can be done w a drill hacksaw and some 3/4 inch wide X 1/8 thick alum/steel stock. use rubber at every mount.

at some point i will post pic but am swamped for a while.

good luck,

I will also post a writeup with pics when im done... ive got a differnet plan than you. witch may or may not work out well, but i want to try it as it has the potential to be very easy and somewhat economical. And if it doesnt work the way im hoping then no biggie but i gotta try.

But basically im using a b&m cooler, earls tstat, a combination of 1/2"npt and JIC 37* flare fittings. Ill be splicing into the the stock retun line most likely at the rubber rubber sections and using a low pressure hydraulic hose (good for some 350 *F and 2500psi)

And for anyone that is interested, there is a definite and visual difference in the sizes of the lines that are used in a single cooler VS a duel cooler application.

The attached pics are of when I switched over to stock duel (thanks Z very grateful for the hookup!) I have the physical measurements in one of my many data/note folders, and will dig them up if there is interest, and I can find them.

I wanted to do a small info post, but never got the time to.

woa who woulda thought... thanks for the pics... maybe for what its worth ill scap the stock cooler and do a dual b&m setup. I doubt it would be much more work and then i can run bigger hose all around.
