With the current interest in an oil catch can, I thought I would add another topic for discussion. Any ideas for an oil cooler? Jeremy7o2 has a Blitz oil temp gauge in his R, and we were seeing the temp spiking during each of our runs on the 'Ring, to around 130 F. I *believe* the GT cars had an option for a transmission cooler; could this be adapted, i.e., could the actual cooler, location, and mounting hardware be used, just run lines to the oil, or would this not be optimal or even good at all? TME made a few one-off oil coolers; does anyone on here have one? Could it be replicated and offered by iPd maybe? *waves credit card @ iPD* If so, I'd be down for a out of box kit!! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> <p>Anyways, thoughts? <p>-Steve<p>EDIT: I'm retarded, just FYI. The temp we were seeing was 130+ <B>Celsius</B>, not Fahrenheit.<BR><BR>

120 degrees isnt crazy hot. A smart way too do it would be to add a water to oil cooler that you plumb into the cooling system. This will keep the temp moor stable and will keep it from getting too low if you use the wrong size air to liquid style cooler.

There should already be a factory oil cooler up on the back side of the engine block under the exhaust manifold. It looks a wee bit like a sardine can sprouting a pair of coolant hoses out its back which then run up over to the water pump. There are no external oil hoses since the cooler is directly mated to the block via a pair of oil passages.<p>Speaking of which, most all late model Volvo engines have an oil cooler of one design or another. The S60 uses the same type of oil cooler as the majority of '99+ FWD/AWD Volvos.

That little thing? Seriously? I guess if you don't do any power driving that's fine, but otherwise.. What a POS! What is the u shaped finned cooler that sits behind the upper grill? I thought that was a oil cooler.<p>I know MTE did some work on a custom take-off plate and sold a few of them back a few years ago (see page three of <A HREF="http://forums.swedespeed.com/zerothread?id=51657&page=3" TARGET="_blank">this thread</A> ). They made about 10 of them and they sold out.

If you have an MT, you could get the OEM Volvo automatic transmission cooler and do some custom plumbing.

Re: (adykes)

That's what I was thinking!! However, this may lead in to another problem though... I remember a thread a while back (how long ago I don't know) that stated it's bad to get into the boost and push the car if it's not up to temp yet. I remember the oil being specifically mentioned as needing to be to temp, so... I guess maybe a custom plumbed thermostat? Set to open at 110? Something like that?<p>-Steve<p>EDIT: Lol, just saw Jeremy's link, and read through Blot's post. BTW, AWESOME car he had... <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> Anyway, THAT is exactly what I'm talking about!! Opens when the oil gets hot, and runs to a stupidly large oil cooler (not stupid in a bad way, just woooow that's cooooool <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">) to cool itself fairly quickly according to Blot! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> Soooo, anyone have any more of these? Could we convince TME to make some more mebbe, if there's enough interest? And finally, what about those running FMIC's? we'd have to figure out a different location, or do exactly as adykes suggests and utilize the stock GT tranny fluid cooler!<BR><BR>

Re: (FORD420diesel)

Also, for those considering this mod, here's something JimLill added as something to keep in mind! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"><p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>JimLill, 20 AUG 2006</b> »</i></TD></TR><TR><TD CLASS="quote">please don't consider this a hijaak.....<br>That's a darn nice cooler but there's a few things I would do different on a very high-perf motor. My POV comes from AMA Pro racing I did in the early eighties and working with some CART guys in that same period. I am employing that info in my own race car which although it is a lowly 120HP VW I still want it to last through 3 hour enduros.<p>- avoid sharp turns in adapters and fittings. Just like your intake system, every turn is a partial restriction. In an oil system, that means pressure drop and less flow . I found a cheap source of 1/2" NPT stainless street elbows that work great. In the lines, you can get bent tube right angle ends if needed.<p>- use -10 SS lines or larger. Not only do they flow more but you get a little bonus oil capacity.<p>- on a wet sump engine, the output of the oil pump is tied directly to the input. That is to say if you lose pickup, you lose pressure for a moment. Real race cars have dry sump systems and have a big tank to feed the pump. On a wet sump engine you can add an accumulator. That would only be an issue for road circuit work but if you get into a big plumbing job it's easy to add one as I did here: <A HREF="http://www.vectorbd.com/users/...2.JPG" TARGET="_blank">http://www.vectorbd.com/users/...2.JPG</A><p>Well, I didn't really intend to take this thread in a single direction, but did want to help Benny (blot). If anyone needs more info, please IM me.</TD></TR></TABLE><p>-Steve

Re: (FORD420diesel)

I'll update my old post.....<p>Oil Coolers come in all shapes and sizes. I have this BMW one in my race car. It is not always possible to keep away from right angle bends, but be sure to use the sweeping bend fittings. See the first picture.<p>While SS line is sexy, you can get push on stuff that is easy to DIY. Aeroquip makes QuikQuip or something like that. I used SS as I have a pile of that stuff already, see second picture below.<p>As to an accumulator, the pix link from Steve is old. I have since remounted mine, but the 3rd pix shows what they look like.<p>The hardest part for the R is making the adpater plate which Benny (blot) had custom made.<p><IMG SRC="http://www.am-rennsport.com/2008Prep/slides/DSC_0911.JPG" BORDER="0"><p>Pix 2 and 3 deleted<BR><BR>

Re: (Helmut Ranff)

Here's what the Volvo cooler/exchanger looks like.<p>Fabbing of an adapter plate is not too hard. Blot's was elegantly machined. A thicker plate could be cruder. You just have to get the o-ring area correct.<p><IMG SRC="http://ah.pricegrabber.com/product_image.php?masterid=704373053&width=400&height=400" BORDER="0">

Re: (JimLill)

I don't want to do any group buy, but I'd guess if 10 or so people got together getting some plates made would not be too hard.<p><BR><BR>

Re: (JimLill)

I'd be down for a group buy. I will shoot Blot and Discomm an e-mail this evening, and see if they either still have access to facilities to produce these or at least have the CNC files to have them made. Reference, Blot's post in <A HREF="http://forums.swedespeed.com/zerothread?id=63919&page=4" TARGET="_blank">this thread</A>:<p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>blot, 20 AUG 2006</b> »</i></TD></TR><TR><TD CLASS="quote">Sorry, didn't take any pics during that install, but I will when the next cooler goes in. Essentially, Discom had access to a CNC machine and had the guy custom make us an aluminium take-off plate that fitted the oem oil cooler location behind the engine. The oil lines were then routed along the front subframe to the left front fender where my oil thermostat is located. from there, the oil lines are routed below the headlight to the upper front air dam where the oil cooler sits. The oil cooler is mounted with custom brackets.</TD></TR></TABLE><p>-Steve<p>

Re: (FORD420diesel)

That same cooler is used on a ton of P2 Volvos. You should be able to get a junk one to look at and clone.

So.. we would ditch the water cooled piece and do it air cooled.. I like the idea. I'd be down for a takeoff plate, no problem. Then it's just a matter of sourcing all the hose and whatnot and putting together a kit.<p>Seeing the oil get that hot doesn't make me too thrilled, and I can imagine we could talk some of the other Dutch/German Ring visitors that roll the S60 into picking up the kit too, to help offset some of the numbers.<p>And I might know someone that has an extra old engine sitting around that I could get a good look at that oil cooler/connection spot.. let me shot him an email.<p>Nice work!

Re: (Jeremy7o2)

FWIW: I picked that Behr for my racer as it has enough surface area but didn't block the radiator. <p>It is 22 inches long<p>So you all need to think about where you put a cooler where it wouldn't add heat to something behind it.<p>The factory transmission one is a poor choice/location IMO<p><br>

Re: (JimLill)

Well, with the phMIC installed, there's a good amount of room after the Power Steering fluid cooler and before the AC/Radiator. Since it wouldn't be on all the time, and you really aren't going to use the AC on the track.. that should be a good spot (upper grill area). eh?<p>On that topic, would the PS cooler make a good choice as an oil cooler? Maybe it's not designed for the thickness of the oil or heat dissipation?<br>
