Hey there, I am replacing the oil cooler lines, what size AN fittings and hose do they use? I am going stainless, one hose is ripped, and might as well replace it into a one piece stainless!

Thanks,

 

I'd like to know, too.

 

It is very hard to firgure out what mazda size fitting oil lines are, Also are u planning to use the stock oil coolers? Cause if so u will find it very difficult to find the right an sizing fitting to mated with the stock oil cooler. Also u can but the mazdatrix oil adapter to run your custom oil lines, I think it's like $10 each adpaters.

 

I don't know the stock sizes, but AN10 works well as a replacement.

You can get hose and AN fittings from many places.

Mazdatrix has the best prices that I know of on metric-to-AN fittings so you can connect to the front housing and oil filter pedestal. They also sell pre-fabbed SS lines that you can just buy and install.

I am not sure how to connect the SS lines to the stock coolers, but you could replace them with Mocal or other standard coolers. The stock driver's side (U.S.) cooler has a built-in thermostat. If you replace that cooler, it is wise to include a separate thermostat in the system. Mocal makes several, and you can get them from pegasusautoracing.com.

Rotaryextreme.com sells a few different kits that have all (or at least most -- I don't know the details of these kits) the parts you need.

Does anyone know the size of the oil cooler thread and the connection at the oil filter pedestal thread, were the banjo fitting goes?.. I think it's 18mm, but by what 1.5?..

i didn't use dash 10 as the other lines are smaller so what's the point... dash 8 is the ticket.

Thank's for your help

 

If you're interested I can build you a kit incluiding all the lines, fittings and some brackets for around $250 for steel braided or a litle less for the push on style fittings.
