      XC70 2002 engine oil cooler & transmission oil cooler

      Starting to warm up in Australia and noticing temp gauge running hotter, air conditioning makes it worse. Anyone have any recommendation or experience with connecting and location for a remote engine oil cooler and the same for transmission.

      Look at this thread for the hood louvers locations: https://forums.swedespeed.com/showth...92s-XC70-build Whatever cooler you install, it is superhot under the hood with T2 engine - must ventilate.

      [QUOTE=Exocet;7676729]Transmission oil cooler.

      Are those PEX elbows & clamps??
      This is on my weekend task list, wanted elbows like you used, went to McMaster Carr usually a great source, but all they had in brass is called low pressure Off to the basement to look! perfect timing, tracking shows the rest of the stuff from Summit Racing is due tomorrow. I like the thought of only using two screw clamps at the Magnafine filter. I did the Hayden 11 x 9 with thermostatic control.

      Thank You

      Brass elbows. A combination of PEX and Oetiker clamps. I'm planning on replacing the elbows with aluminum tubing for more gradual bends. Transmission fluid isn't under high pressure. Maybe 10 PSI.

      F--ing Brilliant! Makes for very neat install, I checked some 1/2" Pex 90's and the size looks great for the 3/8 rubber trans line.
      Thanks for posting! id as normal I would see that a week after doing the install.

      I have 3/8" fittings and the hoses fit pretty tight. I wanted to keep all of the hoses behind the crash bar - neater and less risk of damage.

      Here's a thread with some other transmission install considerations:

      https://www.volvoxc.com/forums/showt...mission-Cooler

      I put a transmission cooler in my 2004 a few weeks ago. Other things I'd do while it was open would be too swap the o-rings on BOTH the in & out fittings on the radiator. They shrink and harden over time. Two on each fitting. These o-rings (I'm sure generic will do and can be found - 11 x 2 mm):

      https://www.rmeuropean.com/Products/...325-V4754.aspx


      Many suggest having an extra clip if you remove the connector, like this (I had no issue getting them off):

      https://www.rmeuropean.com/Make/Volv..._-_at_Radiator

      Adding a magnetic in-line filter like this is not a bad idea when you are there plumbing anyway (I put one in the PS system, too - plenty of room/easy access in the return hose along the firewall):

      https://www.amazon.com/Raybestos-515.../dp/B072PQ2XKD

      I found fluid cheapest at my Total dealer, 10qts for $53 US after tax, ask for the T-IV which is what Volvo-rebrands (technically actually Mobil JWS 3309 originally).

      I find Mubea clips/ct clamps so much easier to use and hold better in applications like this. There are cheap generic ones in bins at my local 'Ace' hardware store:

      I added an external, screw on filter. Right in front of the LF wheel. Easy to change!

      The Pex 1/2" fittings measure just under 3/8", looks to be perfect and will copy your routing behind the crash bar

      Thanks again for posting!

      Beats pulling the transmission out and cracking it open to replace the filter!

      I added the 11 x 6 Hayden cooler, mounted in the same place as Exocet shows above. I believe this kit had everything that I needed:

      Volvo ATF is not Toyota T-IV, nor Mobil 3309.

      Yes, also more fluid & more cooling, need to check the garage for a spin on adaptor I pulled off the 66 Pcar and added a Canton Racing 8 micron filter, or if I can find one in town tomorrow. Move the Microfine to the PS line as suggested.

      Thanks to all

      Yes, it is. The factory fill for this was JWS3309; a 2002 XC70 has an Aisin AW55-50 (AW33, etc.). Volvo has a unique internal part number is the only difference (Volvo is 1161540-8). For non-Aisin Volvo-installed transmissions, this does not apply.

      JWS 3309 is a standard.

      Mobil 3309 is a product compliant to the standard. Mobil 3309 differs a lot from Volvo 1161540/1161640. T-IV is closer, but not there yet.

      Aisin 0T4 differs from Volvo even more.

      I've burned about $1k experimenting with cheaper alternatives to expensive Volvo ATF, and have tried many choices. Among these four mentioned ATFs, Volvo is the top choice, then T-IV > Mobil > Aisin. I would actually put Idemitsu Type-TLS before T-IV, but Volvo is still better, because it has a slightly higher viscosity and a better friction modifiers pack.

      Yes, transmission is filled for lifetime. The lifetime of the fluid, not transmission

      Really, it costs $50ish for 4l, you need one like every other year.

      I do 12L of T-IV every 30k. Still pink like a peach when I do the changes but I want to make sure I get all of the old out.

      Modifiers wear out more quicker than ATF gets dark. Especially, with the inline filter installed.

      Went to the dealer this afternoon for a few bits in case something was to break and get fluid, what a waste of time, They had no fluid!, no spare O-rings of clips for the quick disconnects, they had 2 of the plastic rivet / pins for the top of the bumper but on closer inspection they are not correct. So much for them and picking anything up locally.
      Will pick up L of the T-IV or mobile to top off after the filter & cooler install and order some on line later for a change, color is good had it serviced about 25K miles ago with Volvo fluid.

      Thanks for the tips.

      Hi Scottishbrick, Thanks for the info When you say D5 oil cooler I take it you mean engine oil cooler. Is the D5 cooler on a XC70 the same as on an XC90 Thanks

      Yes. Visually verify the coolant outlet and inlet orientation but I believe that they are the same.

      Like the filter as well. Why not use AN swivel fittings for easier maintenance/removal for future instead of the compression clamps?

      Yes, I looked at the AN fittings. While nice, it ultimately came down to cost and how many times will I ever take it apart - probably never.

      Agree, you start with Push on connectors at the cooler and also need them to get into & out of the fluid system and the spin on adaptor keeps from taking it apart. I like and use AN fittings a lot, over time I have quit using AN swivels as they almost always weep oil.

      Correct. I meant barbed or AN not swivel. Misspoke. Apologies

      No worries. If it was someplace visible, I might have used AN fittings and hose, just for cosmetics.

      As often as we pull the motor on the drag car we always have to think about more or less quick disconnects of some sort

      Mobil 3309 is a product compliant to the standard. Mobil 3309 differs a lot from Volvo 1161540/1161640. T-IV is closer, but not there yet.

      Aisin 0T4 differs from Volvo even more.

      I've burned about $1k experimenting with cheaper alternatives to expensive Volvo ATF, and have tried many choices. Among these four mentioned ATFs, Volvo is the top choice, then T-IV > Mobil > Aisin. I would actually put Idemitsu Type-TLS before T-IV, but Volvo is still better, because it has a slightly higher viscosity and a better friction modifiers pack.
      I've put about 500k miles on Aisin AW33, AW55-"X", Aisin U151e (non awd main case) on multiple cars. Never seen Aisin spec something different. Never had a failure, and in regard to Volvo, seen big improvements dumping Volvo dealer fill (unknown actual provenance) and putting in real 3309.

      Love to learn if you can demonstrate; always open to being wrong.

      Can you reference anything? The single UOA of Volvo fluid was disastrous, it sheared terrible.

      Update: I like Exocet's filter location looks easy change the filter pulling 1 splash guard, 1 bolt, BUT PITA to drill it, but all good & mounted. Started late yesterday first time bumper cove removed, 20 min alone taking my time, I can see doing this to change headlamp bulbs as foolish as it sounds :-)
      Mounting my cooler lower using the holes at the bottom outside of the ac evaporator for cross support, will figure out other brackets & final hose routing tomorrow, no work today for a memorial service for a very dear friend

      Don't even have to remove the splash guard to remove the filter. Just reach up behind bumper cover. Yes, it was a PITA to drill. I only got 2 of the 3 screws in.
