which brand of oil cooler?

OZshifter88

Ok i have decided to go with Z1 but just not sure which size i should go with, i would go with the 34r but later on down the road i might want to get the stillen gen3 and from what i read the gen3 will not work so well with the 34r. Will i be ok with the 25r on the track? And will the 25 work with the gen3?

It works with no issue at all. It's just never been corrected on there website. I and several friends here locally have the same setup. This is one way to route the lines. I'm in the process to route them a little differently.

I am going to start with the GTM 25 row and SC supplement kit... if that isn't enough I will look into the dual cooler kit and some other cooling upgrades... fingers crossed

During ZdayZ on the dragon I was getting 240+ with no oil cooler and it was only ~65-70 degrees outside in the morning.

I installed the 19 row with non thermostatic plate (Z1 kit). Knocked ~20 degrees off spirited driving temps.

Did autocross yesterday as part of the ZCON event. A friend from out of town drove my car as well. We did 24 runs with outside temps of >95 degrees! Temp never got over ~225!

At first I was a little worried about getting the non thermostatic plate but living in Savannah Georgia (and talking to Z1) and seeing the results I am more than happy. If I had gotten a cooler larger than 19 row I would have definitely gotten the thermostatic plate.
Best money I have spent on the car yet.

Soo i had the cooler for about a week and a half everything was good oil temps around 180. Was driving home tonight and I heard a weird noise, then my oil light came on and the car almost lost control. I quickly came to a stop and huge fumes of smoke started pouring out from the engine bay. I turned the car off and noticed oil everywhere on the road behind me, all over my wheels and all over the engine.. meanwhile oil was still pouring out all over the ground while the car was stopped. Going to have the car towed to the shop I had install it in the morning and figure out what the problem is.

Anyone have an idea what happend? Has anyone else had a problem like this with the Z1 Motorsports Oil cooler or any other oil coolers? Any help here would be great! thanks

Really need more details. It could be a myriad of things. Blown hose, AN fitting, etc. It may not even be the oil cooler.

daisuke149

cannot say ive heard really of anything like that. The huge fumes of smoke make me think its not coming from the oil cooler as the oil cooler itself wouldnt smoke

Did you check where the oil was pouring out from? perhaps lift the hood to see what it looked like underneath?

there was a member whos oil line i believe came loose onetime but it didnt esesntially blow into fumes.

Dustin@Z1

Wow...definitly get in touch with me and keep me informed on what is going on. 770-838 7777 ext 309. I was just made aware of this issue and would like to hear more details.

I don't know about the smoke, but when I didn't tighten the fittings enough, the oil just started pouring out of the fittings and gushed everywhere all the way behind my radiator. It could be the fact that yours wasn't tight enough maybe? I still don't know what seems to be the issue with smoke and oil light coming on. Oh I did the install with help of a friend.

The smoke was probably from the oil spraying all over a scalding hot motor, and the light would come on if it sensed a HUGE decrease in both oil pressure and amount of oil. Sounds like u ruptured a line/fitting or "hope not" the core.

It wont hurt anything at all as long as the car was NOT run w/o oil and u shut it down right away, it will just be a bitch to clean up lol.

OZshifter88

Sorry that I havent been able to update this in a while. Just wanted to let everyone know of how the situation was handled. It turns out that a small pin that held the fitting in place was either missing or came out and because of that it resulted in one of the lines to come off. From what I understand the smoke I was seeing was due to oil getting on the manifold.

Big thanks to Z1 for sending me out a new fitting very quickly, I was able to have the car returned to me right before the Flat Out Motorsports event at Roebling Road last weekend! It was very hot out there, I would say the air temps were around 98, oil temps never got above 230!!

Dustin@Z1

Excellent! I am glad to hear you were able to make it to the track. I know of a few others who went to that event as well. Did you see a Blue G37 at the event along with MIKE in the THEPOWDERCOATER.com Blacked out 370Z?

As I mentioned before, this type of failure was extremely odd. As with anything else in life...anything is possible. Those pins are pressed in and what allows for the swivel function of the fitting itself. We have inspected and verified all current lines on the shelf for both the 300zx, 350Z and 370Z oil cooler kits.

Any thoughts on coming up for the Nationals and doing that track event?

So are you positive it's the cooler itself? Who did the install? I know when I received my kit from GTM one of the 45 degree AN fitting was tight but not tight enough for it had a very small leak (very mild). So I tighten it down about another 3/4 of a turn and been good since. So basically check the fittings before install them also.
