Oil Cooler Fittings

[Charles89]

Hey guys,

I'm trying to build my own oil cooler kit and I need some help with fitting and hoses.

I've bought:

-GREX sandwitch plate with built-in thermostat (-10AN outlets)
-Mocal 19 rows oil cooler core (5/8BSP outlets)

So I'm just wondering what's the best fittings/hoses to use to join both of them up.

I'm thinking of using -10AN braided hoses, so I'll get 2 x -10AN to -10AN hose and 2 x 5/8BSP to -10AN hose? Is that correct?

Also, any recommendations on where I could get them from?

Cheers

If you're in the western suburbs give HX Automotive a call. They did my oil cooler last week and did an awesome job with a great price.

Thanks, I might give them a call when I figure out what fittings I need lol. But will be installing it myself.

I used Speedflow fittings and hose (115 teflon / black nylon braid) from motorsport connections in Moorabbin https://www.mscn.com.au

Speedflow seem to be the best fittings I have seen, but check out Proflow as well - I think they are cheaper. Bends etc are not as tight from what I can see but the Speedflow ones are off the planet expensive. A good tip is the straight fittings are much cheaper than any of the bends so if you can get away with a straight its a good thing for the wallet.

Google proflow - lots on ebay and I think you can buy them direct from their website.

Might have been Aeroflow I was thinking of - can't remember

Speed flow is Aussie made, aero flow made in China. Even if it costs a touch more, buy Aussie!

[Charles89]

Thanks Paul, I've been looking at speedflow and aeroflow, both on ebay. But I can't seem to find any of those fittings for 5/8BSP, as that's the outlet from my Mocal oil cooler... Any recommendations?

[Ben C34]

Look at their catalogue online, it is huge! The Ebay Sellers would only be selling the popular sizes, not all that speed flow offers.

[paulR32gtr]

Yeah give Motorsport Connections a yell - they haven't failed me yet with being able to adapt to whatever is required. Not sure about ebay but I think Speedflow control the price so generally they retail for same from all dealers.

All the coolers I have dealt with have had AN fittings (JIC) or a metric female boss fitting that you can screw your desired male adapter into. I think you will need an adapter to use the Speedflow stuff on a BSPT but give them a call, tell them what you have to connect and find out your options.

[Charles89]

Yeah, my Mocal cooler seems to have a built in male BSP connection..

But will give them a call for sure, as they are close to me too.

Will keep you guys updated

I've used torquesUK fittings and they're a little better than aeroflow fittings.

Mine are all MSCN speedflow! Awesome gear!

I had nothing but issues with Proflow teflon fuel hoses and fittings leaking, TorquesUK has helped me out many times with braided lines for fuel and oil without a problem.

For oil I prefer the black nylon braid rubber cored hoses for oil cooler lines, as it is very flexible compared to the stainless braid. http://www.ebay.co.uk/itm/10-AN10-Nylon-Braided-Stealth-Black-Hose-1m-/170690866285?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item27bdf7ec6d

here's my Mocal & GReddy GREX setup:

I went for a Mocal core with dash fittings rather than BSP (which might cost less, but cost more after converters, etc.)

[Charles89]

Yeah I think I wanna use black nylon braided lines too.

And damn it, I got the BSP fittings on my Mocal core :S

[Dose Pipe Sutututu]

Well you could use 2x BSP fittings on the core and 2x dash fittings on the sandwich plate.

TorquesUK would have all.

[Charles89]

Had a really really good search for fittings... RARELY anything for the 5/8" male outlet on the cooler...

BUT, I did find 5/8" BSP female to 1/2" BSP male and speedflow fittings for 1/2" BSP female to -10AN hose.

So I'll be converting my 5/8" to 1/2" then use speedflow 1/2" adapter for -10AN nylon braided hose.

Can anyone let me know if this idea is ok?

​I understand that the more joints I have, the more chance of problems occurring......

[scotty nm35]

So you need something like this... http://www.ebay.com.au/itm/AN-10-10AN-Male-1-2-BSP-BSPP-Female-Adapter-Mocal-Setrab-Oil-Cooler-/380572024115?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item589bdc3d33

But with a 5/8 bsp thread tapped into it? They may not exist, you may have to modify one and run a tap through it. I could probably help you if you can't find something local. Or you could run the adapters if you have the room...

[Dose Pipe Sutututu]

Really depends where you mount the core, if you mount it where I have it, between the a/c condenser & FMIC, left from the a/c condensor fan you will not have much room available to fit 2x convertors and 2x dash fittings. Unless you mount it just before the wheel arch where it's also commonly mounted.

[scotty nm35]

The other option is to ditch the mocal for a 12an 30 row, mine didn't cost much.

You could use the smaller Mocal core for the power steering cooler, or it may make a nice trans cooler for someone.
