Hey guys,

I have a 2013 GS which has the old style Z06 air / oil cooler and I may want to switch to the new style Z06 water / oil cooler to cure low oil temps in cold weather.

Does anyone have any photos of the new setup? I did a search and didn't see any. I'm trying to figure out if there is any reason it won't fit an LS3.

Thanks,
Jason

This is the picture of cooler.

That helps. Thanks!

I think there's a difference in water pump and radiator.... Damn....

From the factory, the two hoses connect to the radiator and to the block. Edelbrock's way of installing their supercharger on GS's is to furnish a "Tee" fitting that goes in the upper radiator hose and then the other line goes to the block where the freeze plug goes. No need to change water pump or radiator to go with the ZR1 oil cooler.

You will also need to fab a bracket for the cooler. Edelbrock furnishes one with the supercharger kit. You might contact a vendor about purchasing an Edelbrock kit #15905 that is used when their supercharger is installed on a GS. You can go to Edelbrock's site and look at all the components that are included in that kit.

Thanks Joe. I'll have a look, but I really wanted to stick with a clean factory looking install.... Hmmm... I'll have to do some thinking....

Using the Edelbrock kit won't give you a Hillbilly Engineering look to the install. The bad thing about using the Edelbrock kit is you are paying for a couple of items you don't need since you are not going with the supercharger. Namely the cast aluminum cover and the valley plate.

And its $1500.... I also don't like their heat exchanger as well as the GM unit.... Again, some thinking to do.

Edelbrock's oil cooler is a GM ZR1 unit. Of course, you are paying full retail for it vs a discounted price from a CF vendor like SDPC.

Maybe if enough people contacted Edelbrock, they would offer a kit just containing the fittings, hoses, mtg bracket etc and not the GM ZR1 oil cooler, the aluminum wing or valley plate that really drives up the cost of the kit. Then all you would need would be the oil cooler to complete the installation.

Don't think he will need a bracket for the cooler, just some bolts. When GM replaced the engine in my Z06 last year the oil pan had holes drilled into it for mounting the cooler. The illustration shown above shows where the bolts are used. Items 5 and 9 in the picture. I am pretty sure the GS uses the same oil pan as the newer Z06s and ZR1.

They changed the LS7 oil pan in late 2009. I'm not sure what pan the LS3 uses.

I added the cooler to my LS7, and made a few posts about it. I will try to dig up a couple of other pictures outlining the swap.

Water pump is the same. The radiator is different to allow for oil cooler input. You can circumvent this by using a T-Fitting, like that which is provided by Edelbrock, I have a picture of this somewhere.. Or you can get a aftermarker radiator like the DeWitts A09Z which I did.

i just ordered a radiator with engine oil cooler....z51 oil pipe and it looks factoty...bonus is extra cooling capacity for coolant...

Would installing this cooler be considered a mod to the General and possibly void the warranty?

erick_e

I guess that would questionable. However GM made the change, so you could argue that you were just making a "newer" modification

If GM has standarized on the ZR1 oil pan that would be a bonus. If the OP will check his oil pan for us and led us know if the raised bosses with the tapped holes are on the newer versions of the GS, that would be a help. I know that my early built 2009 Z06 still has the older style oil pan.

You would think that if GM had standardized on the later style oil pan that they would standardize across the board on the new style oil cooler. Doesn't seem like it makes sense to build the ZR1 and the Z06 with one style of oil cooler and the GS dry sump with another style oil cooler.

Yep. I thought about this very issue within the last few weeks. I've owned my Z going on three years now and just noticed recently (today incl) the oil temp does not rise above 135-140. I used 5th gear this evening and it stayed around 156. Outside temp was 36.

One of the guys who had post in my thread suggested a thermostat that can be added to the air (oil) cooler. I have not investigated it yet.

Another said he installed a Z51 style cooler on his Z. I will not consider that for mine because it just too dang hot here in summers.

I do not think it will be very simple to add a coolant (oil) cooler...

The simplest I think is to simply cover the grill which I will do this weekend until I decide what I'm going to do.

The early production 2010's also have the same oil pan. I think late production 2010 when change over occured.

JoesC5

Are you talking about the GS pans or the Z06 pans?

tim414

Z06...mine is early 2010 and same as yours...

Add: My motor assemble date was Sept 2009 and build was late Oct 2009....Jan or Feb 2010 is when change over occured I think....
