Does anyone know where there's a good write up with pictures possibly on installing the dual oil coolers on a touring model or replacing them on an R1/R2? Not crazy aftermarket or anything, just the stock R1/R2 setup.

It's got to be on here somewhere right? I just see lots of aftermarket paths, and the service manual from what I can see doesn't give a good break down on the 2 together.

Thank to anyone looking for their input.

Thanks, but I read that one. =\ Was really just looking for a good line diagram on the front end, more than cooler pics, if that makes any sense. I'm just not sure where the center section goes that isn't as long and the lone end, if that makes sense... Almost assumed it was just lost somewhere on here, but it's starting to look like no ones ever done a DIY w/ pics... Maybe I'll have to get on that.

(Maybe it's as easy as brushing your teeth. I'll know soon enough once I get the front bumper back off. Try and take pics along the way for anyone else that might come along later.)

It's not too bad of a job as long as you have all brackets and hoses. If I remember correctly, the hard line from the drivers side oil cooler to the oil filter is a different length from that of a dual oil cooler FD. I did this a few months back on a customer car (single oil cooler to stock dual coolers) and had to reuse the original, single cooler, soft hose that connects to the hard line to the filter. Single cooler setups have the feed and return hose clamped together. You'll need to bust that clamp open to remove the old feed line so you end up with only the return line (to filter).

I suggest removing the lower radiator hose and AST hose from the radiator to give you more room to wiggle the oil cooler hard lines in there. Hope this helps and hope I'm remembering this accurately as it was a pain in the butt to get the lines in, only to find out that the drivers side hoses were too short.

I just installed a set of dual R1 coolers. Really simple swap. I can get you pictures on friday when I get home of the line routing and bracket placements.

I agree that it's a straightforward job if you have all required hoses and brackets. My customer thought he had all the required parts which wasnt the case. In my case, adding an aftermarket Setrab cooler to the passenger side of my FD was less of a pain than installing an incomplete OE dual cooler setup.

Just did it this winter, not difficult at all. Hard part is getting the hard lines in thru the wheel well. Also a good idea to take off the front bumper. We also took out the IC and intake which helps you to see what your doing. May have a couple of pics I'll check this evening.

Be sure you have everything:

Why not install aftermarket coolers?

As promised
Hope this help, you may also need to take out the battery box if you have one, driver's side cooler is the same as what you have. So take your own pic before disassembly:

(And not installing aftermarket because I'm not planning on really going HP crazy. Was a touring, now it's closer to an R2 w/ JDM late model twins. Can't beat changing from a single to a double for around 150-200. ^__^)

Just wanted to add a bit for those of you who are looking at doing this , the hardline from the filter to the single oil cooler is the same , But the Hose to the left of it is longer .

BUT when replacing the stock hose with the longer hose you must Remove the Power steering pump , and Air compressor to loosen the hardline that goes to to the oil filter pedistal because there is no space to remove the hose

Also PLEASE remember to sand / heat , or replace the crush washers otherwise you are likely to have a leak from there .

FWIW you don't have to remove the bumper to install OEM dual oil coolers. The only difficult part is snaking the hard line. Here's an illustration of how you connect the lines that someone (apparently Wan) made a long time ago.

I cant imagine installing the passenger side cooler and Duct with the Bumper on haha no bumper makes things somuch easier specially since you need to Lose the Oem hardlines just having the coolers EXposed makes things much easier

I did this install last fall. I took the bumper off, and cross brace that the you see the hard lines underneath in the above pics, and the wheels in front. I did not have to remove the radiator hose or loosen the power steering pump. You just need to feed the piping in from the passenger side and work it through to the drivers side. I did this by myself but it would have been easier if I had someone pulling on one end as I pushed from the other. You will need to purchase a hose that connects from the engine block to the passenger side of the hard line if you do not already have it because the hose that goes to the drivers side oil cooler only is too short.
