Hi,
I have been searching for an oil leak all day on my 2006(new 2007 model 2.2 crdt santa fe) after a couple of hours searching I have found it even though it is quite severe.
The leak is in between the oil cooler (square object under the filter) and the oil filter housing.
The reason I could not find it was because it only leaks when the engine is started from cold and it leaks quite bad.When it heats up there is nothing.
Now my question.
Is ther a kit I can get to repair this area ? (gaskets or o rings) ?
Or do I have to replace the oil cooler or the housing or the whole lot.

Thanks for taking the time to read

welcome to the forums :00000732:

if you remove the oil filter you will find that the oil cooler is held in place by a large nut, it may well be that this nut is not fully tight and that may cure your problem. if not you can undo the nut and remove the oil cooler and you will find there is a large rubber 'O' ring that seals it which can easily be replaced

Hyundai does but seem to have just the "O" ring. Saying I have to purchase the while unit. Do you have the part number for the ring? Thank you

10 years is a long time ago! and I'm pretty sure Diesel was never sound in the US, so what are we after here?

My 06 santa fe 3.5 SE...
I am leaking oil at a cold start, then not as much after. There is a coolant assembly connect by where the oil filter is located.
The place I got it checked said I had to replace the whole assembly. But I seen on the forum about tightening the nut by the filter and or replace the O ring. So what is the part number for that O ring in that oil coolant system? Or do I have to replace the whole system for $700?

cooler 2641039650
washer 2641039650
Bolt 2642039650

Presuming there would be a seal on that cooler to th ebody. I'd try nipping the bolt up or if the coller has a seal if it's removeable like an o-ring maybe a good bearing/seal shop can measure and get one that way

If you are in the US Fastenall should have an o ring. And I have seen Hyundai oil coolers for the Gen Coupe for under $70 new on eBay. They are a rectangular shape though. Mount the same.

If it were me, I pull the unit and see if an O ring could be duplicated at the parts store, etc.

Same company, you will find kia and the Hyundai logo both stamped and they use the same numbering system. But a motor or trans may not necessarily be the same spec of have the same features. I've seen someone get caught out on a motor with a differing head missing sensors.

I have a santa fe elite awd diesel 2.2 crdi and it has I believe an oil cooler leak, as there is oil in the coolant as well. Is this a full oil cooler replacement or "O" ring only, thanks guys.
