how necessary is the oil cooler?

Thinking about a radiator upgrade and an oil cooler. Do you really need it? Is there a good option with real external fittings? Thanks.

Junk yard tranny cooler work?

I had mine removed 4 years ago and I haven't had any problems without it in the desert southwest. My vote is that it isn't necessary at all. It is nice not having to worry about the oil cooler lines rupturing and making my Defender a crispy crawler.

Not really needed. 87-98 RRCs and 03-04 DIIs do not have one.

thanks. I was just thinking about the fact that my 700 hp C6 Corvette doesn't have an oil cooler.

Yes, kind of silly on a rover unless you are driving in the desert at 5k rpm, but still ....

I have revised my opinion since that post, or more accurately I've gotten more detailed in my feelings on it.

The setup, as from the factory, I'm not that much of a fan of. Keep it, ditch it, no real difference I don't think other than that I feel it helps balance the temperature better between the oil and coolant, which keeps the block more dimensionally stable (all opinion, not based on anything else). But because it's plumbed through the radiator, it doesn't add and additional overall cooling capacity.

However, an EXTERNAL oil cooler is a different story. An additional radiator, drawing from a separate heat source, I feel is a very real benefit on trucks that tend to have so many cooling system problems not related to the oil cooler.

-Hans

p.s. Shane, which code Vette do you have? I found it odd your C6 didn't have an oil cooler, but our C5 does. Looks like only the F55's don't have coolers. The Z51's have a small one, and the ZO6's have a much larger one. My old Starion also had one, even if it was just an pipe looped around a couple times in the path of airflow.

Not really a fair comparison. The LSx engine is about 50 years more modern compared to the Rover V8.

Also, I think its biggest benefit other than the obvious, is that it increases oil capacity. On vehicles prone to develop leaks at the drop of a hat, having a little more on hand is not a bad thing.
