NRB Z06

Where is the oil cooler located ?

The oil cooler is the small rectangular block that is in front of the oil filter.

Why the hell there isn't a large core air radiator for the oil cooler exposed to airflow from the front of the car is beyond me. Having the oil 'cooled' by the engine coolant alone makes no sense to me. It's great for getting oil temps up quickly, so perfect for emissions and gas mileage testing; not so good for keeping oil temps down when the car is under stress.

THANKS FOR THE INFO.. That explains why i can't find it. I am going to forgo the BS mods and work on a real oil cooler.

IF the engine cooling radiator has enough capacity these oil to engine coolant exchangers work quite well. It should be plumbed so that it is in the return flow from the radiator so at that point there is a large temperature differential between the oil and coolant. This type of cooler does bring the oil up to temperature more rapidly and avoids having exposed oil lines and cooler subject to damage. The more effective heat transfer avoids the issue of pressure drop through a lengthy and restrictive cooling circuit. Oil to liquid coolant exchangers can be extremely effective but everything depends upon the engine cooling system having sufficient capacity and this is where a problem may lie in the Z06.

The 06-09 Z06's had the air/oil cooler that still let the oil get to 285* or above on track work (240-250 would be much better). They also can take 20 miles or more of highway driving to get the oil above 150*, which is still too low. As indicated above, if the radiator has proper capacity the water/oil cooler is much better, both in easy driving and in track work.

Agreed that a far greater capacity radiator would be the first step, and one that GM would have a hard time denying warranty coverage because of.

On the C6 Z06 we ditched the oil-to-air cooler and put an oil-to-water cooler in the Dewitts radiator. It did a better job keeping the oil temperature stable in road racing conditions and also helped get it up to operating temperature sooner.

Is there a higher capacity radiator available for the C7Z06?

thebishman

Do you think this would be the solution then for the C7 Z, or since there is already an oil/water cooler installed, would an additional oil/air cooler perhaps in front of the water radiator be a better option?

I wouldn't add anything in front of the radiator. I would like to upgrade the radiator, but there is absolutely no room.

Exactly what I did on my Nissan 370z and no more over heating issues (limp mod) at the track...

Same problem in 1996 with the Mustang Cobra. It overheated after a few laps on a hot day. The overheating was solved with installation of a double thickness aluminum racing radiator. Even after adding a centrifugal SC, it still had enough cooling.

Unfortunately, people here are saying the Z06 has no room for a thicker radiator.

The aftermarket will come up with a clever solution. Fingers crossed.

I will take a water/oil cooler any day over the air to oil. They switched over for a reason.

Good discussion here. In case anyone isn't sure what we are talking about, here's a link that shows the production oil cooler: http://www.corvetteonline.com/tech-s...e-power-curve/

I don't see where there would be a lot of air flow around this cooler, and its close proximity to the exhaust header isn't helping the situation. Just my 2 cents.

Unreal

Airflow isn't what cools it. It is a water block. The car pumps water from the radiator through it. Doesn't need any airflow.

Just what I was about to post. Wrapping the header will likely help a lot.

WilliamCall

Thanks for clarifying that (for me).

Anyone have experience with this guy?
