New cooling idea?

[Gojeep]

Came across this on one of the Aussie offroad forums and was installed on a Nissan Patrol. Some other trucks that were competing in the winch comps ran it too. Thought it might be a new idea for a XJ as never heard about anyone running this system on a Jeep. Have seen it some where in the racing field or old trucks long time ago though.

It said "This is the new water cooling system installed that runs water out of each of the water jackets in the head - it keeps the temp cool and equal throughout the motor whilst helping the vehicle's performance overall. The idea behind the setup is that it regulates the temp of the water in the engine. Normally the back of the engine is hotter than the front. This method keeps the engine at the same temp - or near to - throughout."

Would be nice to see some dyno runs with it.

If you can get a look at some decent underhood pix. of the NASCAR rides, you will see that this is a VERY common mod, and in fact the Chevrolet Performance Guide book details exactly where to tap the waterjackets, and the pros/cons of different locations. I might have to look into this if I have any trouble with my 4.9 turbo stroker not wanting to cool down. Thanks for tthe reminder of this mod, GoJeep.

I wish I would have thought about doing something like this before I stuck my engine back in.

Excellent update on where else it has been used. If you ever find a web site that gives some details about it, could you post it here too. I spoke to the guy the picture is from and it has solved the cooling problems he had had during winching compititions and is very happy with it. If I ever have my head off of some reason like a cam change, I will look into doing this as well.

I've got a head sitting here on my bench and I can get a bunch of pics for discussion purposes if wanted/needed.

Once you find a water jacket, what would you do to tap into it? Maybe drill a 3/8" hole from the exterior into the jacket and either tap (preferred I'd think)it of weld in a bung to attach the hose?

Would you run 6 lines? How do you size these lines? Maybe about 1/6 of the size of the original flow lines. I'd want to maintain the heater too.

Wouldn't things get awful crowded with the injectors and all?

opposite side of head?

I've got a polished and ported 7120 head awaiting a trip to the machine shop to get a 3 angle vavle job...

this is mighty interesting stuff

That sounds interesting.
Anymore info on these competitions?
Can you provide a link?

I asked him for more details and he gave me the name of the place that performed the work. I did some research and found their web site: http://ontrack4x4.net.au/
I dont see a email there so might have to ring them for you for more information. I dont really even know what to put into a search string to see who has information on the web either?

I just got off the phone with him and he makes the components in house. The hoses are 10 mm which is close to 3/8" for you guys. He developed it as they had pinging problems on the turbo-ed petrol's and this system allowed more boost. He did also mentioned that the water pump must be a high flow and I showed him the Hesco one on my site which he says would do the job. Another interesting point is that he places a restrictor in the upper hose so the radiator does not get pressurized higher as well. He found it raised the block pressure to 30 psi and stopped the water boiling off the jackets and so keeping the water against the walls giving the proper heat transfer. He left only a 16 mm/5/8" hole in the plate. Just trying this might be worth while by the sound of it. You might just be able to try a large washer held in place by a hose clamp inside the upper hose or even just up against the radiator inlet.

Just found this plates here but might as well make something out of brass or aluminium.

Would it need to be brass or aluminum? I've got some thin stainless steel washers left over from another project that have a 5/8ths opening that look to be about the right size, I know they're available at any good hardware store so you wouldn't have to manufacture them.

[Gojeep]

Stainless would be fine too. Just not steel from a corrosion point of view. Let us know how it goes but you may need a high flow water pump to get the best results.

Just putting a reply in so I can subscribe as I never look in this forum it has been moved to.

I didn't move it here for you, mate.
I moved it, because it's advanced.

depending on the situation stainless could be worse than steel it suffers from crevice corrosion and and when starved from oxygen pits and is amazing how fast it breaks down.

This mod sounds very intresting.. and seems like it could be a low cost mod too. One idea popped up of mine was to use 3/8 tubing instead of the 3/8 rubber hose. This would clean up and look nicer, and keep the lines in place better than rubber hoses. Just adding an idea. :)

Would look like you are running two fuel rails or NOS! ;)

[Fryphax]

Looks like an interesting idea, I might have to look into this when I swap in my stroker motor.

[GermanXJ]

Good stuff I may try this on the XJ I am racing to Africa may save our ass. Thanks

Sounds very interesting. Just came back from 6 weeks there last month. Great place for a Safari and the roads out there are bad enough and hate to think what you will be racing on! I have a few shots of our trip there up on my site. The link is under the maps on this page. www.go.jeep-xj.info/TripsIndex.htm (http://www.go.jeep-xj.info/TripsIndex.htm)

Thanks for the pics. I am very excited about the race. We will be in the desert mostly.

[dan89XJ]

Anyone have any update on this mod ? Any more research gone into it ? Just curious.. I havent looked into it more myself.

[Gojeep]

If you cant source the fittings locally through places that fit them to race cars as mentioned, ( they may only have 8 cylinder versions? ) then you can email the guy that made the ones in the pictures here in Oz. ontrack_4x4@hotmail.com This is not normally a public email as he does not check it regularly and only got it out of him to save any of you interested from the USA from ringing him instead.

Go Jeep, Thanks for the pictures from Africa, they are awesome. It looks like you had a great time.

Was the trip of a life time. :)
Was a 6 week long National Geographic moment!

I don't know too much about how the coolant flows in an I6, but.. What if you ran some of the coolant going back to the radiator through a heater core or some other cooler, then ran that cooled coolant into the head through the octopus setup?

Or maybe tap into the water pump supply and run it to the head, I don't know if this would be possible like I believe I've seen on some SBC's. Or does the water pump already push coolant through the head first, then into the block? I'm thinking this would do a better job of keeping the head cool, possibly keeping detonation at bay on strokers/boosted/higher compression engines.

Stainless would be fine too. Just not steel from a corrosion point of view. Let us know how it goes but you may need a high flow water pump to get the best results.

About this. The engine blocks are cast iron, and while they do corrode, even with the inhibitors in anti-freeze, wouldn't the corrosion levels of mild steel in coolant be roughly the same as the corrosion levels of a cast iron block?

The pump pushes into the block then up into the head, out of the head and back over the pump to the radiator.

The biggest weakness of the system I can see is the increased number of seams and joints- a brazed together manifold might work a little better, but there isn't a lot of room under there and I'd want to keep diameters minimized. I'm liking the idea more and more as I think of it, but I wouldn't do it till I can see one in person and talk to someone local who has done it. Mabe some of the drag race guys?
