Oil cooler install. How i did it.

There are many ways to install an external oil cooler but wanted to share the way i did it.
Basically I have made another cooling project just like my other ones, with alot of thought.
First the location of the External oil cooler. I bought a B & M Oil cooler (Part # 70266) for its size and the location in which it was to be installed. Since the Talons ABS motor is there in that location I had to mount it under which works perfectly to have the cooler right in front of the bumper opening. Heres the location of the mounting screw.

One is all you need sice the SS line will aid it on the bottom as a mount. I also wanted to have some flexability for engine movement. The oil cooler would have the slight flexability to move with only one mounting location.

The 98 Talon came with a very large Stock SMIC shroud. Even larger than the 95-96 Talons. I saved it for this purpose. What I did was removed the install tabs (these tabs hold the shroud to the stock SMIC) and cut a slit for the AC condensor bottle. You have to flip it so that it matches the driver side curves. Now on the original passenger side location, the shrouds bottom hangs lower than the front bumper opening. Flipping it would make this hang on top with the bottom of the bumper opening flush with the shroud. Than to attach it I used an L bracket.

This will aid in directing the oil flow directly to the oil cooler. To further aid flow you have to extend the shroud. We all know that air always travel in the direction of least resistance. So with that in mind you want it to find its way.
I went to home depot and bought a piece of sheet metal. (26 guage) which costed me $5. I cut it so the shape starts at the shroud and ends right on the side of the oil cooler. I used a large vise to make straight perfect bends where needed.

Now for emergency I wanted to still have the oil cooled even in heavy traffic conditons or even at idle in super hot summer days. So I incorporated a Fan. I bought the smallest slim fan I could find which was a 7 inch slim fan. I bought the one with Curved blades hoping it would be quieter. Since it spins so fast, it makes a little noise. I mounted it straight to the oil cooler. Obviously the B&M oil cooler is smaller than the fan so I had to block off a part so that all of the fans air flow goes through the cooler. I used a dremel and the same sheet metal. I screwed it on the fans housing with really small screws. For the top mount of the fan, I used a small pipe as a spacer and a long screw.

You can see how I covered the lower half of the fan.

Now its a matter of installing the cooler/fan setup and making -8an lines.

Heres what it looks like from the outside.

I still have to mount the fan control in line with the coolers oil lines and make the plastic cover to finish the wheel well. I will be updating this when its done.
For the fan control I bought the Derale 16749. That way its automatic. More when I finish the other parts.

Very good. I don't like the fan install part of it, but good work anyways. They make smaller fans, btw.
In all my searching, the smallest slim fan they make is 7". I needed a slim fan due to the tight clearance. If you find it, post it.

Yamaha r6 fans are slightly smaller, or most any on the newer rockets.. Your idea works fine though.

That cooler is also very expensive.. I love his install i just don't believe an oil cooler was needed.. Not to mention it blocks most of the airflow. So i hope it flows alot of air.

If you add the price of the cooler, fan, and thermostat it's not that much cheaper and you get it in one nice complete package. I agree about the fan position, I would use it in puller fashion instead of pusher or not use one at all.

I tested the install and trust me alot of air flows through it. This fan is super fast and since its right against the cooler, the air flows through it nicely.
As for price, I actually got it on Ebay for about $40 back in December of 2006. I was lucky.
Also I thought about making it a puller but due to location and limited space, I had to do it this way.

You could have used a B & M oil cooler with the fans built in. I used one on my Supra and it worked great. Check out summit- http://store.summitracing.com/egnsearch.asp?N=400004+309928+115&autoview=sku
Look at the measurements of that cooler your link direct to. My area of install would not let that cooler fit. Thats why I made one. And the fan on that cooler is 7" Just that the cooler is 13" in height x 9" wide to accomodate the fan size. My cooler is 6 high x 11 wide not including the fittings or the mounting plates.
And a correction on the cooler part number. Its B&M 70273

What temperature does it turn on then?

Nice finished product buddy! your new fp 30 will like cool oil as well as your engine. I'm gonna put one down there too accept I have a larger unit and a 2gb eclipse front bumper. I don't think I'll use a fan but maybe if I come accross a bike fan like ^ said.

You deserve a :tree:

You should change your sig pic to an engine shot.:D

the turbo pic is good though too.;)

I will change the sig to the engine shot...............Done! (Yeah you seen my engine:D )

The fan turn on temp I'm not sure yet. I bought an adjustable unit (Part number above). I'm waiting on someone in my other thread to lert me know what temp does the Evo/90 DSM oil cooler let oil pass into the external oil cooler. No one seems to know this. I would let the fan cycle at the temps where oil is circulating in the cooler.
I did look into Motorcycle (Sports bike) fans but they were all too bulky to fit in my location not to mention pricey! My fan costed me $25

Forgot to mention one thing. For the water lines that went to the Stock oil cooler this is what I did.

The water neck, I removed original spout and I tapped to 1/8-27 pipe thread and installed a cap with a 1" brass pipe.
Image


For the water pipe, I cut off the angle off the spout and tapped it with the same tap and screwed in a Plug. This was a super tight fit. I had to get a special pipe Key (.99 cents) to screw it in.

i didn't like the way most people do it with a small piece of hose and a screw inserted with a clamp. My method is a super clean install and stealthy

The second of the coolers listed is actually about the same size, the B&M 70298. The core size is 8.5" X 6.5". Glad it worked out for you, the B&M kit uses a 160 degree thermostat BTW.

Theres a thermostat built in. I don't think your information is correct. Same with evo oil cooler/filter housing.
Then how come on a cold engine, i cranked mine and watched oil flow through my oil cooler? If there WAS a thermostat that wouldnt' happen.

Well I have been doing alot to my car with it being down so heres updates on the fan control setup for this oil cooler.

Heres the Fan control. I painted it Red to match the car to make it more Stock looking/clean. Its location makes it easy to access for adjustments.
Image


Heres where the sensor is located. Its routed inline to the Inlet of the oil cooler so that the oil temperature entering the oil cooler is the temp that the oil cooler fan control will see.
Image


Heres the finished cooler setup
Image


I still have to figure out the splash fender cover. I'm not sure if I should cut it to make a screen back for air to flow. Have to figure out if its a low pressure spot.
