Oil Cooler Installation Ideas
 

I will be installing this Hardin Marine thermostatically controlled oil cooler:
http://www.hardin-marine.com/detail~ID~858.aspx

The current oil system routing is a stock 2004 496HO with the exception of an aluminum oil filter bracket that came with the DANA Vortex Torque Flow exhaust system which did retain the stock oil filter location and hoses.

I am very interested in any and all layouts and experiences, especially with pictures of any and all add on oil cooler installs especially that are hull/floor mounted I would prefer to retain the existing oil filter mounting and remove the stock 496HO oil cooler but I am interested in anything others have done.

Nordic Rage and Nordic Heat installs are particularly of interest.

Thanks in advance.

I'm not falmilure with the 496,. Mine a 500efi, I mounted mine to the 2 upper bellhousing bolts.made a little extension to raise it some,Mine also has a 1/2 spacer to space the cooler back some. there a lot of wire in that area on the 500.My oil thermostat on on the port side.

the other pick is using the 2 block upper holes, not mine

Hope this gives ya some ideas

Thanks Rob. Very helpful.
What are you referencing here: "the other pick is using the 2 block upper holes"?

Bill

Mine uses the bellhousion to block bolt holes, around 2 1/2 x3/8 bolt,because I needed the space up and out, the other that uses just the 2 upper block holes was made by a friend , he didn't need the clearance, so he had a tighter,more com pack looking install.

My bracket ,plate steel silver color.mounted to the oil cooler c clamps.

also try and get the One that have the o ring in the clamp mine doesn't ,I put some black tape trying to cushion the cooler,mine dents it some

I'm not good at whats in my head then putting it into print:drink:

Hey Strip,
Very nice work!!
Guess you spoke with my buddy Jason about the Slingshot 540/Whipple 4.0 builds I'll be doing for him.
Hopefully you won't mind if I pick your brain a bit about the rigging in that boat :drink:

Thanks,
Dave

Thanks,Yea we talked Hustlers for about a hour:drink:Nice guy, he's going to have a hell of a ride when he gets it going!!!

Hollar anytime, I gave him my cell.


Dave he must of snuck out and bought it without you'll knowing:evilb::evilb:Don't give him to hard of a time:ernaehrung004:

Thanks again Rob.

I was luckly enough to be along when Jason checked out the Hustler Slingshot. A very cool boat. I was instantly envious.

Bill

Price helps too:drink:

Anyone with hull or floor mount approaches for the oil cooler?

Plane Silly,

Thanks, that will probably be the approach I will use since there is no room on the back of my engine and the decking of a Rage for a rear engine mount.

Where do your inlet and outlet oil lines to the cooler connect to the engine?

Where did you get the oil cooler hold down clamps?

Thanks in advance.

Bill

Heres my old Scarab,its a big industrial cooler from Teague,if I had to do it again, i would prob mount it to the motor or on the stringer below the motor, i like the idear on everything mounted to the motor, self contained, you can pull it off the dyno and put in boat and be running in a hour,keeps it simple.

Its brass in the pick:ernaehrung004:

Rob,
I see you went to AFR heads in one photo. How much did they help over the GM heads you had?

Thanks again. I would rather install the cooler on the engine as well if it would fit but that is not looking likely with my tight clearances at the engine rear.

I also have a remote oil filter mounted to the transom and those are the lines that run to the oil cooler.

Linnie that was a buds motor showing me how he did his bracket,Wish I had some alum heads, I really need blocks first:drink:

Yes, nice guy indeed. He got a little bored with his 100mph Heat so it was time to do something else.
He didn't really sneak it on me; he actually flew me out to give it a once over :) (Thanks to Bill (Rage) for toting us around!)
He stepped out of the Nordic box with his choice and I think he made a good one :ernaehrung004:
Guess I'll be learning a bit more about these Slingshots; I actually have a 525EFI Whipple motor from another one on my operating table :D

Talk to you soon,
Dave

Just a credit card away. I am ready to do something else. Kinda washed my hands of projects but getting a little bored now. I want to see what Dave does first.

GM now is 1800 new:eek:, was trying to find a freshwater used one. I guess Ive been lucky on the blower moters 3 seasons and just little bs stuff..

Linnie you thinking of going bigger?:ernaehrung004:

Thanks.

What oil line size did you run to and from the cooler?

Rob
I was hoping to find some Merc 575SC tops complete with blowers & throttle bodies. None seem to be moving around. May look for some whplles or go bigger

Plane Silly,

ttt

Sorry Rage, I don't know what size they are it was installed when I bought the boat. If I where to guess I would say 3/8 ID.

Hey Plane Silly, thanks for your help.

Bill

I used 3/4 inch lines on my oil cooler and thermostat. The cooler didn't have a built-in thermostat so I used a Hardin Marine billet filter block/thermostat. The set-up worked really well, but spent a fortune on Russell hoses and fittings to make it look pretty!

heres a chart
http://www.candsspecialties.com/stor.../plumbing.html

looks like #6 could be #8, I use #10 boat and cars

Well you accomplished your goal of making it look real nice.

Good looking engine. I could open the candsspecialties.com url but the holly.com url would not open.

In your picture showing your oil cooler, are the 90* angle water fittings 1" NPT/1 1/4" hose nipple? If yes where did you get them?

Plane Silly, Your oil cooler is held down by what appears to be typical T bolt hose clamps but there is also some sort of plate as well that is bolted/screwed to the floor which is mostly obscured by the cooler. Any idea what this floor mount hold down assembly is comprised of and where it can be purchased?

Thanks for all your help.

Bill

Sorry I can't help much with the mount. The Tbolt clamps are made to the floor mounts. I'm sure CPperformance or Eddie Marine carry something like them.

Thanks Plane Silly. Yes they do but it is the high end/dollar billet aluminum stuff. I am looking an alternative. Do you happen to know who installed your heat exchanger? I sent your picture to Dustin Whipple who said those were not his brackets.

Bill

Is the water supposed to go to the sea pump first then to the oil cooler or can I run the water through the oil cooler on the way to the sea pump?

I would run it into the seastrainer ,then pump and then oilcooler .

Merry Christmas big boy, see ya in Louisville: 575 X 2 = 98 - 100 MPH. Rock on Linster!
