All Things Chev

Apologies mate, only meant that we should all think about having compressor air intake lines dragging from the coolest/driest known locations in our Trol/Hybrid old faithful combos:-)

OK, finished the additional oil cooler installation today. I specifically went for this extruded aluminium format as its robust, easy to clean and has great heat transfer characteristics. The unit also holds another 2L of oil, so helps with the overall sump capacity that is tiny on the Chev. All up cost was circa $150 for the cooler and $120 for the hose and fittings from Pirtek. I will be installing an open area perf sheet guard to protect from the burn hazard. Can't say how it works yet as typical Melb, went from 28 Deg and sultry to 17 deg and thunderstorms in 4 hrs, so will have to wait. I used a hose and fitting combination that does not require hose clamps, rated at circa 450psi from memory for this application.DSC01971.JPGDSC01970.JPG

The clearance is approx 100mm above the winch rope and with the UV cover folded back, its easy to monitor the rope spool pattern as well. Lastly, the unit is 450mm long x 130mm wide x 75mm high, all aluminium extrusion, single pass flow. Total cooling length is 900mm.

@PeeBee mate, they are a very cool looking extrusion, pardon the pun! Any chance you could kindly sketch out a side view of what its guts would look like so I can wrap my head around this great looking new system! Having troubles in my little noggin imagining its internal workings, Cheers mate!

Same but different http://www.partzfinder.com/22_Extrud...p/pce-3405.htm

Here you go. I was chasing a similar unit advertised in the US that was 700mm long, would have been a perfect fit between the ARB bullbar rails, but it is no longer made, distributors in both Aust and USA refused to allow me to make direct contact, which is a shane, but thats business i guess. The extrusion is very neat and the internal fins are a critical part of the system. I have seen others without the fins and am sure they would not be as efficient.DSC01972.JPG

Awesome gents, double Cheers!!

OK, took the beast out to see what impact the oil coolers have. Its a mild day, circa 22 degC. Temps are into and out-of the cooling loop. Cruising around in 80kmhr traffic in the suburbs.

Water radiator - 76 degC in, 60 degC out

Oil cooler - 74 degC in, 40 degC out

Having full airflow onto the oil cooler fins without obstruction works well, very happy with outcome.

Niiiiice... good result cobber.

I've been thinking of doubling the cooler on mine but might rrsehole to old rad style and put in one similar to yours.

Where did you source the Cooler from?

Ebay, link below. Its the longest unit I could find. Could not locate the manufacturers either. It is 100% possible to run a pair of these as the inlets are 1/4" bspp threads and improve on this result perhaps. I run this unit in series with the existing unit. I don't like the existing unit as the air does not go thru it, more it sheds heat by air flowing over th front surface and radiates heat onto the a/c coil in front of the new BD radiator.

Damn you Phil, looks like a ripper outcome! Nearly halving the oil temps on a single pass must be a cracker design mate, truly well done :-) !! With such awesome efficiency found today do you think installing oil thermostats for next years snow trips might be back on the cards? My Serco radiator style jobbies and yanky Derale oil TS are all still staring at me on the shed shelf and now I’m totally lost as how to move forward or restart :-(
