The diamond shaped oil cooler. Where does it connect to? Water lines? How do you tap into the radiator water lines to connect to the cooler? I would like to install it on my GS .

I dont know about the GS, but I looked into upgrading my 09 Z to this cooler. It mounts directly to the oil pan, in the two bolt holes shown below.

The Edelbrock EForce has an adapter bracket that mounts the cooler to oil pans that dont have the bolt holes (pre 2010 Z06), and an T fitting that connects to the radiator hose, instead of the factory radiator. Not sure about the GS models

This looks quite simple. From the picture I see it is a water cooled oil filter. The water from the engine goes thru it and enters the radiator and back to the engine. I don't think the radiator replacement would be necessary since it is a metter of just tapping into the water line. Maybe somebody else would chime in with some more info.

It is a fluid to fluid cooler. Oil enters and exits two of the ports. the water comes from two locations as well. One of the locations is in the block itself, by removing one of the factory freeze plugs screwed into the block. The other fitting is in the radiator itself.

These cars ZR1/Z07 and some GS cars have different radiators, hoses, and water pumps.

We had to start over when we did our new radiator for the cars because of all of the changes to them.

So when you do your trick on the cars. Do you remove those coolers and install the front cooling units? My car is 2011 GS automatic. Is it worth it to install the pan cooler or better to install the regular front cooler with the long lines?

one question in a 06 Z06 what will be the most efficient oil cooler.

0Anthony @ LGMotorsports

Depends on the car.

I haven't had much of an issue with the Z06 fluid to air coolers, depending on the setup.

From what I have seen the OEM setup on these (ZR1 setup) may need some work. The ZR1 is having a hard time keeping water temps down to a normal level, but oil temps seem to be ok. In testing of our own ZR1 it is nothing to see those cars hit 240-260 water temp in 8-10 laps on track, stock. Higher HP cars it is even worse.

We had to come up with something this year to keep Lou's car in check along with our more heavily modified cars and track customers. So we designed a new radiator for it, and have been able to keep not only engine water temps but oil temps down as well. Lou's ZR1 now see's 174-184 water temps and 190-205 oil temps under normal driving and 188-197 water temps and 220-230 oil temps under track conditions...so setup right, it works very well.

At the same time the air/oil cooler in the Z06's has worked well, but again track cars generally need a larger radiator and by dropping water temps I can get the oil temps back in check as well..but not as low as the above setup.

So the answer isn't as cut and dry....depends really on the setup of the car and how you use it, if you want to change it.

Anthony, I know the ZR1 has a different waterpump, but are you positive the Z07 does? I was inquiring into your radiator here http://forums.corvetteforum.com/1578828836-post54.html but never really found out whether it was as direct replacement for the Z07.. My understanding is that the only difference between the ZR1 and Z07 radiator is the inlet (quick connect), but I noticed some sort of tube attached to the top of your radiator, and am not sure what this is for.

Yes, it is possible to do this without replacing the radiator. The picture below shows how Edelbrock does it with their EForce kit. The outlet hose connects to the upper radiator hose via a T-fitting.





I don’t know about the LS2/3, but not all LS7 oil pans are drilled for the oil cooler. I believe in late 2009/2010 they started to use the same pan as the ZR1 which has the mounting holes. The EForce kit also has an adapter bracket which allows the cooler to be mounted to those pans without the predrilled holes. You can kind of see it in the picture above.

Although this is not a corvette engine, this is how the cooler connects to the radiator hose.

I knew the E-force had a new part for it, but haven't had a chance to get it on the car yet (have one coming in this week).

As far as direct factory items, yes it would have to have a different radiator.

Part of the Z07 package should be the including of the ZR1 radiator, and oil cooler.

The water pump change, actually took place in 2009....doesn't need a ZR1 pump per say as those are completely different but the 2009-current Z06/LS3 cars have a different pump with different hose connections vs the 2005-2008 cars.

Anthony,

As far as I know the only difference between the Z07 radiator and the ZR1 radiator is the quick connect hose. Will this radiator work with standard Z06/Z07 upper hose? Since your Z06 radiator deosnt have the oil cooler inlet.
