anyone put an engine oil cooler on their vehicle? If so, were you happy with the result?

Gossy,
I fitted a oil cooler to my 6.5l chev in the troopie. Because of the small amount of oil these engines carry it was the best move to keep the oil cool.
Even the old 2H had an inbuilt oil cooler.
Most modern diesel engines now have them standard.
You certainly won't go wrong by fitting one.
RA.

looking at the PWR 21row (280 x 198 x 37mm). I assume they fit in front of the radiator?
If so did it affect the cooling efficiency of that (or does the cooling of the oil assist in the overall cooling anyway)?

It was a similar size and yes it sat in front of the a/c condenser wish is in front of the radiator.
Although the 75 series has a small fontal area for cooling I had no problems with cooling when towing a 1.7 T van. She always sat around 76C and would move up to 90 C on occasions then the fan would cut in and bring her back straight away. This mainly happened on very steep climbs or when the wind would swing behind you.
Yes if the oil is cooler, then it has to lighten the heat load on the radiator, so all ends up about neutral. It would take around 1 hour for the oil to reach full operating temp.
Just for a bit of interest loaded prime movers will run quite often run around 100 to 105 C with the Horton fan running constantly.

thanks for the feedback. Sounds like it's a fairly good "bang for your bucks".
We had some heating issues up North on our last trip (nothing major but showed the standard configuration struggled).

It won't get rid of overheating, that is another problem. If you say what vehicle you have others maybe able to help with that.

Hi Gossy
As Rockape suggested, you need to work out what problem you are trying to solve first.
It is possible to overcool your oil which is why some oil cooling systems run a thermostat to maintain the oil at sufficient temperature.
Fitting a cooler in front of the radiator means you are feeding heated air to it which reduces the
water cooling efficiency. This may not matter if you have spare cooling capacity but if you are trying to manage an overheating problem then a separate air flow is desirable.
If you have developed an overheating problem then I suggest that problem should be identified and fixed first and then you can work on increasing the overall cooling capacity.
Regards
A

yep agree. There is no 'problem' as such. We spent 6 weeks up North and found the car sat around 100 degrees on the open road. Manageable but probably not good long term. Since then I've installed a larger capacity PWR radiator which I'm sure will help. The oil cooler is just another step to bring down the temperature a bit.
cheers,

Hi Gossy, read you post with interest. We have just returned from a trip thru the
Kimberley , across the Nullarbour , via Eyre Peninsular then up the centre home to
Darwin. I noticed that in the top part of the Peninsular and up the centre the Patrol, towing a 23 Ft. van was sitting on 100°C at times. This concerned me but as it happened intermittently carried on. Should I be worried ???

I'm probably not the best person to ask for a mechanical view (hence why I ask the guru's here). It was in those exact
places where our car struggled though. We weren't towing but we did have a fair amount of weight inside.
It was frustrating to be in that heat and not use the a/c as much as what we would have liked to manage the heat. Life's too short to sit in a 40+ degree car :)
From a personal perspective having my basic dash board gauge sit above 3/4 was too high for me. My aftermarket gauge was showing it climb 10 degrees just by putting the a/c back on. I'm sure in those conditions an oil cooler and a larger radiator (which I've now got) would make a big difference.
What I don't know though is how this would affect the car in cooler conditions like Tassie or high country (will the car not get warm enough??).
