Oil Cooler Setup

Cam takes a stab on getting an oil cooler on the C5 without too much modification.

Setrab Oil Cooler Mount and Kit

What this is

I needed an oil cooler, ASAP. Unfortunately for me, oil cooler kits for the C5 cost an arm and a leg! This kit turned out to be sort of spendy, but now you, the reader, can benefit from my trial and error. The brackets I've developed use the radiator support structure as a mounting location, and feed the in/out lines through the radiator shroud.

What you need

So, hypothetically, this mounting style can apply to any oil cooler. I specifically designed this setup for the Setrab 50-920-7612, but the inner plate can be adjusted to suit any distance between the mounting flanges of any cooler. The 50-920-7612 is 16" wide, but you can definitely fit a wider cooler in the area directly in front of the condenser.

Ok, here's the list:

  1. 1x Setrab 50-920-7612
  2. 2x Setrab 22-M22AN10-90 ProLine Oil Cooler Adapter Fitting
  3. 2x Setrab 22-M22-AN10-SE ProLine Oil Cooler Adapter Fitting
  4. 15' of AN10 braided PTFE hose (I didn't use it all, but I believe the line lengths are more than 10' combined...)
  5. 4x MATCHING BRAND PTFE AN10 hose female ends
  6. Any brand LS oil thermostat adapter
  7. 2x Inner bracket; 3/16" 5052-H32 Aluminum
  8. 2x Outer bracket; 3/16" 5052-H32 Aluminum
  9. 8x M6 x 10mm SHCS
  10. 6x M6 x 18mm FHCS
  11. 8x M6 washers
  12. 22x M6 flange nuts
  13. 27mm/1.06" inner width square u bolts, M6 threads Amazon
  14. Blue threadlocker
  15. Step bits for modifying radiator shroud
  16. Tools for cutting SS braided PTFE hose
  17. Razor to trim front air dam

Optional: Dampening material that fits between the

Once I get another car to install this kit on again, more pictures will be present.

Instructions are forthcoming!
