Oil coolers and fans

[Norbie]

If you look at the photo above you'll see the oil cooler is mounted above the intercooler so it won't do any "interwarming", and it's also directly behind the grille so airflow at speed will be about as good as it gets. I should mention that my car has had a history of overheating problems since doing the 2JZ conversion so I'm doing everything I can to keep the temps down - I doubt an oil cooler fan will do much but every little bit helps right?

Karls got a good point, a growing number of bikes have fans - they might be more efficient than a 15 year-old AC fan from ABC wreckers.

Setrab do integrated coolers with fans in a few different sizes.(called fan packs)

amazing what a new mobile phone, a laptop and a capped call plan can do for your internet access

norbie - check out the aux rad fan on a jza80 - i reckon thatd fit if you wanted to persist

I'll check it out next time I see a JZA80 at the wreckers!

i have a spare available

search on SF for a pics of a rdiator shroud. should find one.

Next time you're in the vicinity could you measure the diameter of said fan for me?

[ed]

justin should be able to measure it for you - hassle him

[Mr DOHC]

whats the dimensions of your cooler

[clubagreenie]

Its about 170 across with the blades about 45mm long so its got a pretty large hub.

I wouldn't bother unless this is for an endurance racer, or something that gets thrashed, then idles, then thrashed, then idles, repeatedly, never shutting down.

Idling doesn't overheat oil like the cooling system will, with its pretty poor low speed circulation centrifugual type pump. The low bearing loads & piston temps just don't give off that much heat to it.
The oil temp will still climb some because it is still removing heat from the head & valves & crank, but'll be well below its breakdown point.

Also, any fan & ducting will probably windup restricting airflow when moving!
Also,also thermo switch & relay/valve for 12V/flow??

...mmm

yup, that'd be the 2JZ supra

Or the 1GZFE Century

I heard what went on at dubbo

just hazzarding a guess, a fan that looks ideal size would be the side vent fan from an aw11 mr2. or alternativly the intercooler fan from an sw20 turbo. both look like they would fit on there a treat and both move a bucket of air.

I use the 120 mm pc type fans x2 on the front of my trans cooler , in summer the air neally burns u , 2 of them pull ample air for a small cooler , they are not water proof, just dont soak them . mine run with the ign and havent died yet in yrs
