Oil Coolers location/types for FI Zs.

The Oil cooler should be sandwiched between the intercooler and your radiator. A 34 row cooler will help alot! Also depending on your model and model year you will want to remove the factory cooler if it is present.

It should look like so:

IC --- Oil C --- RAD --- Engine

I have the 4.5L and two 34 row Setrabs tied together and on an 80* day my temps may see 160-180* peak...

I purchased an oil cooler kit that contains the 34 Setrab core and thermostatic plate. I had planned on placing the core behind the intercooler but in front of the radiator. However, I'm now having second thoughts on if this will even be beneficial. There is already minimal air moving into the engine bay. Using this air to pass through the intercooler, oil cooler, and radiator seems like overkill.

So those with similar setups, did you see a beneficial drop in oil temperatures? Did you mount the core between the intercooler and radiator?

AAM is working on a liquid cooled oil cooler. I have thought about selling my air cooled oil cooler and going this route.

Thoughts?

You have a boosted Z without any type of oil cooler? And you're only seeing 220? 220 doesn't concern me too much. That's not what I would consider too hot. And I would avoid a liquid cooler completely.

Are you concerned about the oil not getting hot enough to boil off moisture?

To answer the OP's question, mine is between the IC and radiator, with a Spal fan on it set to turn on automatically when the oil gets over 210 or so.

Yeah I do. The car hasn't been driven much at all the last 6 months due to winter. I've had the oil cooler kit just sitting in my garage till I could get the time to put it on. Just cruising on the highway and staying out of boost the oil temp sits right around 220. If I start driving the car hard temp rise over 245 or so. I consider that too hot.

I'll throw the cooler on and also look into fans to see how much the temps drop. I guess worst case scenario is the coolers not enough and I'll have to go another route.

Thanks for the input everyone.

Those running SPAL fans, where are you mounting them at? Trying to figure out the clearances.

Cruising around on a 90deg day I stay between 190-200 unless I'm really beating on it.

You also might want to check your tune and make sure the radiator fan is adjusted to come on earlier and harder. Mine runs full out all the time with the AC on.

I am the same... When I dont push it the car sits between 160-180... I would do block off plates but I can get to them lol
