I want to add a second stock oil cooler in series. what do I need to adapt the cooler to -10 braided line.

thanks again

Dave

-10 is alittel big, but the thread size is 18 x 1.5 I beleive. It is not that easy to find these locally, go to a perforemance shop and tell them waht you need and what you are doing and they should be able to help you out.

thanks for th quick reply. What size are the racing beat lines and should I order adapters from them.

Dave

Stock oil lines are just a little over 1/2", I would go with -8.



If you can get your hands on an Earls catalogue, they have everything in there to make up your own lines.

earl fittings tend to leak.... i use ONLY aeroquip. I think most of the upgraded oil cooler kits use -10 also.











I use -12.

Racing Beat sells adapters for this specific application and their price is reasonable compared with Earl's or Aeroquip. They are for -10 fittings. Make sure to order crush washers with the fittings. The coolers should be plumbed in parallel for best efficiency and least pressure drop. Twin stock oil coolers is common place with the SCCA ITS cars. Parallel is the defacto setup. The Ts to do the splits are available from Aeroquip.

how about we try a little useful info here? wouldnt you like that mr. whoever made this topic.



to convert just your one stock cooler to lines I'd reccommand this:



(3) 18mmx1.5 -> -10AN Adapters (find it on Summit, AN to Metric Adapters in the plumbing section, this goes to your rear iron, and inlet and outlet of the cooler)

(1) 16mmx1.5 -> -10AN Adapter (same section as above, this one connects to your front cover)

(1) -10AN 45 Degree Hose End (use this on the front cover)

(3) -10AN 90 Degree Hose End (use this everywhere else, some people say you need a 120 degree fitting for one of the oil cooler hookups, so you might wanna check clearances before ordering)

(2) 3 foot sections of -10AN braided lines



Now the key thing you NEED TO DO TO MAKE YOUR OWN OIL COOLER LINES is to go and get new stock crush washers, i think at mazda theyre like $1 a pop, describe them to the guy and he should be able to figure it out. I got mine from the dealer he knew what i was talking about rather quickly, which is amazing.



Enjoy.

Or easier yet:



Go to the local hydraulic hose shop, take your old lines with you. They cut off the old lines, braze n adaptor fitting of the hardlines and make you up a set of lines. My local shop charges ~ 75 for this service.

Thanks for all the great info. I'll put them in parrallel instead.now I know what I need.

Thanks Dave
