Hayden / Napa / Summit oil cooler kit. Anyone?
 

EDIT Note: Since installing this kit, everything seems GREAT. Please make sure if you want to try this yourself to please read through this entire thread. Theres stuff added to this every so often. The latest addition is important enough to post up first. If you are going to buy/try this kit, sincerely think about picking up 4 of the following T-Bolt style hose clamps:

Hey all,

The other day I was going through my local Napa store, and asked the counter for advice on Oil Coolers for my car. The guy showed me several in his computer system, and he had one in stock. Here it is:

The oil cooler kit is "Made in the USA"

From Napa:
From Summit:

My first thought was this oil cooler was designed for SAE and non-metric vehicles, so I asked to take a look at the kit they had in stock. For one, the sandwich plate IS of thermostatic design, and the kit DOES include the 20mm sandwitch adapter to thread onto a 370z. The included ~12 feet of rubber hose didnt look like it was rated for oil, so I wrote down the number and did my reasearch - The host itself IS rated for oil, at 300PSI peak pressure. That being said, it might be better to eventually get at least -8 AN hose/fittings as I dont trust the host-barb fittings and rubber for years and years.

Summit.com sells the same kit as Napa, and it is even LESS expensive. Napa wants $139, Summit wants $96.

Anybody try using one of these? I know its of 'fin' type but so is our power steering cooler.

I'm very tempted to give it a try...

I think this would probably work out fine with some better lines and at $95. If the fin type
cooler starts to get ruined by rocks or debris you could replace with a better one.

The hose itself isn't going to fail but I wouldn't trust the simple burr fittings with the high pressures that our oil pumps put out. There is also no mounting bracket for the cooler so all you can do is tie wrap it to something. I could use it as a supersized power steering cooler though!

What is the factory oil psi ?

Actually, the zip-ties included with the kit are designed for you to fasten cooler directly to the radiator/condensor by snaking the tie through them. There are included 1/4 inch rubber spacers that allow the components to stay seperated when finally squeezed together. The slight downside I believe would be how to get the zip-tie through the stock pieces but it should be OK. The cooler weighed practcally nothing. With oil I'd imaging it wouldnt weight more than about 2 lb.

Not totally sure (wish upRev had it in the logs) but likely ~40 at idle and ~110 at anything higher 2000 rpm. It probably doesnt go any higher than about 110psi. Someone else chime in please if you know this.

Edit. Found out from serching google that a 350z can hit about 115psi oil pressure at full RPM.

Thanks, good to know..

I was just doing some more reasearch on this, and; since I dont really like the Brass/Barb/Burr hose fittings myself as they do tend to be a failure for a lot of things... I've been subjectivly looking at a different style of fitting. I located this at Advance Auto Parts (and likely other places).

I'm in the process of looking for a better hose clamp than the worm style. I'd like to use/find the T-Bolt style commonly found with fuel injection systems; only they are hard to come by at ~1 inch diameters.

Also, Amazon.com sells this oil cooler kit for $85 located here:

AN Fittings

If it was me doing it, I would go with the stainless steel line and the AN fittings.

Keep us posted if you do this. I am highly interested in doing this. I don't track my car much, but know an oil cooler is a must even in hot summer days.

But what about the cooler end fittings? The fittings on the cooler itself appear to be part of the flow tube, I can't see a way to change those out?

IMHO, I think this is better.. Good price too.

I know everybody wants to save a buck. But somethings as this I wouldn't. Are you just looking for a basic oil cooler kit? Best just to use GTM, Z1, or Stillen. Plus there made for are cars. So far as hose length and all.

I think Im gonna try this kit out. I found out that Napa will price match Summit since I'm within about 50 miles from the main Summit store. The only things I'm going to change are the hose clamps, and I'm going to try replacing the brass barb 3/8 NPT fitting to something steel.

Just FYI, the hose barb fittings if paired with the correct ID hose are very secure. We incorporate those into a lot of assemblies at work and trying to get
the hose off after it's installed correctly is a real pain. We usually end up just
cutting a slit in the hose to be able to pull it off..

Agreed! :tiphat:

I would suggest to 1st support our Vendors before looking elsewhere. Napa is not paying to advertise here! I hope the OP understands.
Thank You.

^ It would be nice if our Vendors sold setups in stages. So you can go bigger later on when it's needed but already have the hardware there.

They already do, Stillen offers a 19 row, and a 23 row, And GTM offers a 25 row, and comp version 34 row.
These have been tested and use quality cores and custom hoses. Thats one of the reasons they are pricey but well worth the $$

That doesn't even make since. Triple's already cleared up one part. But why would you go bigger later. Just get the right size the first time. It wouldn't be an issue.

:iagree:

Go Big or Go Home ;)

10-4

well if fun on twisty backroads on hot days is your thing it is better to get the smaller cooler so your oil will reach temperature for regular driving, the larger cooler are best for cars that see track use and need the extra cooling or turbo setups.

I went ahead and took a shot at trying this cooler. Napa in my area matched a price printout from SummitRacing.com so it was a pretty good deal for a local sale. I ended up also grabbing some wider hose clamps at the time because the kit includes clamps which are particularly small in size. I just used screw style clamps for this.

Install went well enough for a universal kit. I ended up not having to cut cut anything from the car at all, and routed the hose around supports and out of site; using zipties about every 6 inches. The cooler itself is securely tied directly to the radiator and condensor using the included special one-way zipties. The install looks very factory from the front of the car, and the cooler is right up against the condensor which makes it look clean. I should note at this point that the aftermarket coolers from our vendors usually place the oil coolers further in front than how I've installed this; meaning that my setup would be worse for heat disapation due to it possibly obsorbing heat from the condensor and radiator. Aftermarket coolers are closer to the bumper skin; similarly to our factory power steering coolers which is likely much better for cooling.

The two biggest note about installation is with the included 20mm adapter bolt from the kit, and also fitting the correct oil filter.

1. For whatever reason, the entire bolt mechanism is about 1/8 inch too long, which didnt allow the sandwitch plate to install securely. All I had to do was cut/machine about 1/8 of an inch off the nut/sleeve side of the adapter bolt and then the sandwitch plate could be tightened perfectly tight.

2. The oil filter was a bit of a concern at first, but after trying a few dozen in the napa isle I finally found a good fitting one which wasnt overly huge. I cant really post the number of the filter I bought, because they actually had three filters on the shelf all with the same number, but one of them was actually smaller in diameter! When looking to get the right filter, make sure the filter has a 20mm thread and not overly long. The adapter plate -REQUIRES- a filter which is larger in diameter than stock for a properly maited surface. Without this, you will spring some high-pressure leakes. I bought both filters that fit and will just have to keep this in mind when shopping for one in the future.

I have my worries and concerns about the absolute length of life of the included rubber hose. Although it is rated for 300psi, I really would not put 100% trust into that. In the future I may speculate purchasing about 8 feet of -8 AN hose, some good T-Bolt clamps, and fittings to attach the hose to 3/8 NTP at the plate.

The outcome is pretty good thus far. Atlanta weather was pretty hot this weekend, at ~80 peak. Crusing around I saw oil temperatures fluctuate between 190-200, whereas before I'm pretty sure I would have seen 220+. Merging swiftly onto the highway saw temerature of 205, but then ~5 miles up the road the temperature dropped back to 195.

The oil will still hit 220 degrees; if you drive really hard from stop light to stop light after about ~3 lights or ~10 hard pulls to redline in 1st/2nd/3rd gear. That being said I'd imagine most coolers would suffer from this, as the lack of airflow is a sure temperature killer. I might go buy a small cooler fan and see how she goes.

I do have an IR temperature gun, which always caught the cooler at about ~170 degrees.

Recap:

-Maximum temerature seen with Napa cooler: 220 w/o long term airflow (195 average)
-1/2 inch hose (-8 AN) could use some slightly better hose but its OK as it is
-Slice 1/8 inch off the adaptor plate bolt for proper fitment
-Oil filter needs careful size consideration (Possibly a manual effort)
-System may need/like a small electric fan to aid in faster cool-off

Final note:
I think this sytem is fine for daily driving use or short term spirted driving like Autocross. I'll have to get back with the outcome of a mountain run, but I'd say for almost sure that this kit would not be the right choice for turbo charging and track usage.

Be careful that you left enough slack in the hoses where they mate to the adapter plate. We've seen a few failures from hoses pulling free from the adapter plate presumably due to engine twist.

If you mount the oil cooler in front of the radiator you can take advantage of the A/C mode kicking on the extra cooling fan and drawing air through the radiator and your oil cooler.

Pictures of it on the car.

You have pics of the sandwich plate? Is it a thermostatic plate also?

Total cost.. ??

you could cut the bulged ends of the tube off of the cooler and flare it for a jic connector and run an lines to the cooler core instead of clamping the hose on eliminating the possible blow out and clamps tearing through the line.

Since or Sense? The prices these oil coolers are start at 500. For someone who has less then 3K on the car and has been told numerous times of oil heat being an issue in the summer. I just need a basic setup. I would have been happy with the setup the 350Z came with. While this doesn't make sense or since to you, it does to me.

I dont have pics, but yes, it IS of Thermostatic design.

About $100 thus far. If you buy this kit from Amazon you might spend less at ~$85. The reason mine was $100 was because I bought it from my local Napa (who usually sells for $139 but they price matched Summit). I prefered local sale in case I was to return the product. You might need ~$3 worth of better host clamps to get you started, and you also need a $5 oil filter that fits correctly.

That... is a GREAT idea. I'll put that one on my list!

Sorry for the honest spelling mistake. Sorry it bothers you so much. If you need a basic setup that's fine. I respect that. But you stated that you wanted to see stages of these kits (which they have) in case you wanted to go bigger later. You can go bigger now with no issues and not have to purchase another later.

Yes, Hayden does have stages of these kits. This one is their 'light' duty kit, and on the manual/box it says good for a Chevy v8 engine. -Ha! The larger kits are more expensive to the tune of about $200 or more. This page has the kits available from Hayden. Look at the last three on this page:

Hayden - Transmission and Engine Oil Coolers

I really was just teasing about the spelling error man. I'm not a spell Check Grammar Check Nazi. If we were talking in person you would probably bust out laughing. I was...

I'm not really sure what kind of setup I will need for the summer. I purchased the car in the late fall and its been sitting pretty much till recently. I'm not sure why they didn't just come with the same sandwich plate the 350Z came with. Most likely I'll end up with the first stage Stillen kit, but it is nice to see others trying something cheaper for an added benefit.

No problem man. Good choice though.

Its been about a week since installing this kit, and all is well. I've checked my hose/connections about 6 times since installation and everything look great.

I had felt a little iffy about the screw-style hose clamps, so I went ahead and place and order for some clamps made by a company called Mikalor from Amazon.com; the only T-Bolt clamps I could find online which would work with the kit's included hose.

Amazon.com: Mikalor 301902-0 3/4-13/16" 19-21mm Ss/Stl T-Bolt Hose Clamp: Industrial & Scientific

So if you are going to buy this kit, you probably should think about snagging 4 of these T-Bolt clamps up as well for added hose security.

I am kicking this product idea around, because in Michigan, there is not the same heat index as the deep south. Anyone order this one yet?
