hey can anyone tell me what size earl's fittings i would need to buy for the stock oil cooler? thanks

 

Both on the oil cooler are 18mm - 1.5

 

x3 18x1.5 to -10
x1 16x1.5 to -10
x3 -10 90 fitting
x1 -10 45 fitting

 

awesome, thanks, btw this isn't for a rx-7

 

They don't have to be Earls as well. You can get them from your local hydraulic shop, Mazdatrix, etc.

For the record, there is a writeup in the Archives that covers this in detail.

 

hey does anyone have a direct link to standard hose fittings? i know earl's are great but wow they can be costly to switch my whole setup. http://www.copper.org/applications/r...ng-graphic.jpg i'm looking for something like that but with a 1/2" barb

 

i was thinkin of chopping off the head of the stock bolts and then clamping a hose over that but i'm not sure how those threads won't leak, its hard to explain but i hope someone understands.

 

Don't hose clamp things on the oil cooler. We're talking 80 PSI here, and if it lets go you can start saving for that rebuild...

Thats said, there are hydraulic fittings available with hose that is designed to be clamped or simply pushed on. But you will likely find the price to be the same as the AN stuff.

Fittings are not cheap.

 

not sure if this matters but i'm running this on a supra, its 55psi and my oil relocation kit from summit is just reg clamps.. no problems with leaks or anything

 

Do whatever makes you comfortable. Mazda used banjo bolts because they're very reliable. Hose clamps are not. Personally I would never trust the engine's only source of lubrication to a few hose clamps and regular rubber line. At the very least, get proper high-temp and oil rated line from a hydraulic shop and use t-bolt clamps.

 

yea the hose i am using is def not heater hose, it's oil rated and very thick
