Howdy,

I need to replace the oil cooler lines and oil cooler. I bought a new oil cooler with AN10 fittings. To get the lines made I need to know what kind of fittings connect to the engine. I have looked around and can't find any or what they are.
There's a place near here that does custom lines and can make them but they want me to remove the lines and bring them in. Which I really want to avoid.
So does anyone know what kind of fittings are on the engine end on the oil cooler lines?

Thanks...

 

18mm banjo fitting.

 

Cool, thanks!!!
I guess they do look like banjos.

You can also remove the banjo fitting and just go straight with AN fittings.

 

Don't bother attempting to adapt aftermarket coolers to the factory lines. They are weird thread pitches and nearly impossible to match up. I have seen some people tap the inside of the oil line ends to accept an -AN to NPT male adapter, but I don't recommend this. Get rid of all the stock lines and replace them with the proper -AN stuff. Remember that most aftermarket oil coolers do not have thermostats, which are built into the stock coolers. Running without thermostats will contribute to engine wear as the oil will take much longer to reach operating temperature. Some good info can be found here http://www.fd3s.net/oil_cooler.html

 

Ihor, he did say:

 

The oil line place said they normally just reused the old fittings which sucks. I would think that a fixed type of fitting would be better than a banjo type. I just don't know enough about oil lines and the pressure and what I need. I'm worried I'll put on some crap and not know it until there's lots of smoke!

 

Here's what I did: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/diy-dual-oil-coolers-856548/

 

I wasn't sure about the thermostat, we're in Florida and doesn't get too cold, maybe 30's. It bothers me to have another potential point of failure. This engine already self destructed once with some kind of oil issue.

Is there special hose to use for oil lines?
Do they have to have special fittings? My son said he thinks regular clamps would suffice?
I was think high pressure would require all kinds of special parts?

thanks for all the info...

 

18mm x 1.5 (-10) adapter fitting will screw into the front cover and oil filter pedestal. then use -10 ss lines and fittings. thermostat is optional and more involved to plumb in to your system.

if your choose not to run a thermostat, install an oil temp gauge and wait till the oil is up to operating temperature before driving the car. this is something that should be done regardless of a thermostat installed or not. monitor your oil temps while driving to ensure they dont drop to low. i run my oil system without a thermostat and never see oil temps below 165 deg. F. using a monster 34 row earls cooler. (my temps are measured after the cooler aswell)
