Oil cooler

Finally finished fitting my new oil cooler setup so I thought I'd post up some details and pics for anyone whos interested...

I used to have a GReddy oil filter relocation thingy, but I've never been that happy with the hose and connectors (it uses push on connectors with worm hose clamps), so I decided to go with proper aeroquip hose and threaded connectors. Not cheap, but top quality and no chance of a leak or hose coming off. So I ordered (all mocal stuff from ThinkAuto) :-

19 row oil cooler

oil thermostat

oil filter side takeoff plate

remote filter plate

aeroquip hose (3m) and various fittings, seals and adaptors

The plumbing goes like this:

engine -> oil filter takeoff -> remote filter -> thermostat -> cooler -> thermostat -> oil filter takeoff -> engine.

The remote filter is before the cooler as apparently filters work best on hot oil. The thermostat is there so the cooler doesn't come into play until the oil gets hot, so it doesn't take ages for the oil to warm up on startup.

The cooler is mounted behind the front bumper passenger side, just in front of the washer water tank. My FMIC pipe is a bit in the way, so it was a bit awkward, but I fabricated some brackets and it went in there pretty well. The thermostat and remote filter I juggled with before deciding the only place they would go is with the remote filter under the car in the same place as the GReddy one was and the oilstat on the side bulhead in the engine bay.

I mounted the cooler a couple of weeks ago, but thought I didn't have enough hose so I ordered some more - turned out I had plenty to start with! I fitted the rest last weekend, but I had a leak where I had used rubber O rings to seal the connections to the oil filter takeoff. Bad idea - the correct thing to use are bonded seals, I put those on today and it's sorted at last!

Here's some pics, I can post up the complete list of stuff I ordered if anyone is interested.

Good info and nice install Simon, it's on my list of things to do

I was having a look at PW's earlier today.

nice write up. could go i ians tech section

good work. i just fitted one of the greddy oil relocating kits and the pipe connections were real tight fit. tightend up the clamps real tight after reading they were not too good. had no leaks and feel confident in them.

what sort of price was your kit and any model numbers

GOOD WORK

Nice one Simon.

Ive got the filter relocation kit, oil cooler and tranny cooler sitting in the shed waiting to be fitted, from memory the kit came with rubber hoses and push fit connections.

Do you have part numbers etc for the aeroquip ancillaries?

I think they will be the best way forward, what did you use on your threads as a seal?

Yeah, my GReddy never leaked and I had it on for over a year. As long as you're careful installing it it's OK. I had a job getting it off in fact. You just have to be careful you don't overtighten the clamps, and it was always a bit of a niggle in the back of my mind that it wasn't quite as good as I would like.

My oil pressure sensor is plumbed in with an adaptor which is the adaptor in the list - I'm going to use a sump pliug adaptor for the oil temp sensor now.

Nice one Simon.

Dave

Most of the connections are JIC, they don't need anything as a seal, they have a coned seating. Where the male-male union goes into the filter takeoff that is 1/2BSP and sealed with a bonded seal. Kind of like a washer with a rubber bit in the middle. The remote filter plate I used has 1/2NPTF threads, so the male-male unions on those seal by the thread deforming slightly as you tighten it. You can use PTFE tape if you want on those I think but it's not necessary so I didn't bother.

I did a similar install couple of weeks ago, have a tranny cooler and oil cooler mounted there. Ducting on the left is for the compressor hsg airflow.

nice write up mate i enjoy looking at stuff like this, is there any difference using an "external inline" stat such as you have or one of the built in stat oil filter sandwich plate ones

Simon

Cheers for the parts list and costs.

I have a kit waiting to go on from Paul E..both Mocal coolers, but came with rubber hose and push ons as standard.

Ive have no stat to go on so do you know which of the connectors etc i will need for the two coolers? bearing in mind the kit came with male - male adapters.

I need the female to hose swivel adaptors x4 and coolers to hose x 4, i think thats all for now? The prob is im not up to par on the different thread sizes etc?

Any help appreciated

Dave

Well you can't use one of the built in ones with a remote filter, they are sandwich plates with the filter in the same place. There's very little room down there anyway, so with an extra sandwich layer it would be very tight.

You need to know what type of thread you have on your male-male adaptors. It could be -10JIC or 1/2BSP or something else. If you don't have a oilstat you'll need 6 connectors, two on the take-off, two on the remote filter mount and two on the cooler. Whether you need 90 degree ones depends on where you mount everything and where you route the hoses. I used a 90 degree one for one of the cooler connections and for the outlet of the take-off as it needed to head down.

Cheers Simon

Who did you get your bits from? was it direct? and if so do you have any contact details? i will discuss further with them.

ThinkAuto, they manufacture Mocal stuff. Web page is here. You could just buy some more male-male unions if they aren't -10JIC ones. In fact I've got a few spare that they sent by accident.

thanks for that simon, its just a space issue knew there had to be a logical explanation

The remote filter plate I used has 1/2NPTF threads, so the male-male unions on those seal by the thread deforming slightly as you tighten it. You can use PTFE tape if you want on those I think but it's not necessary so I didn't bother.

I take this back, you DO need PTFE tape or it will leak. I learned this the hard way as I just had to drain the oil AGAIN to seal them properly as they were leaking.

NEVER, EVER use PTFE tape on engine oil fittings. You should seal flat parallel male threaded fittings to a flat mounting face with Dowty seals.

do you notice any difference?

The fittings on the takeoff are parallel BSP and are indeed sealed with dowty seals. The ones on the remote filter mount are NPTF, so are sealed with PTFE tape and the fact that they are done up bloody tight and the threads therefore interfere. That's what ThinkAuto aka Mocal say. Sorry for any confusion!
