D6D engine overheating

[.RC.]

Another hot humid day, got it operational. Made all new side and bottom radiator baffles for it, they are not hard to make.

Gave it a run this afternoon in 34C heat for a couple of hours and really gave it the beans.

Looks like the problem has been solved. Could not even get it halfway through the green.

RC, what did the new core end up costing you?

 

[.RC.]

It was $3900 + GST for a copper one.

Great result.
Are you still going to run Toyota coolant RC?
I see you can get CAT ELI, the glycol free ELC, for $91 inc. for 20 litres.

 

[Delmer]

ELI is not antifreeze, and is to be used at 7.5% concentration, in distilled water or similar, so 20L would go a long ways. Interesting that it uses ELC extender, and not just more ELI. Also interesting the nitrite and molybdate levels. For those of us in the North not familiar with it:

ELI is an extremely good option for any location where engines never get cold enough to freeze. It has the same inhibitors as ELC which protect from corrosion and cavitation. In a hot climate that’s all you need. TBH I wouldn’t put coolant in any machine in Australia, only ELI.

The price that I posted is for premix.
Concentrate is around $1500/20 litres.

At that price, I might be picking up a few drums. I have a few machines ready for a coolant change and why pay for stuff with antifreeze when there is no need.

Well I still have a cooling problem. I was into it today fairly well, doing a lot of second gear work, and about 2pm was when the cooling problem really got going. The air conditioner was really struggling to keep me comfy and cool I think the cab is just too big.

Do you need a Turkey farmer special?

 

[.RC.]

Not sure what a turkey farmer special is, but those big old cabs take a lot of energy to cool.

Well the new radiator has been a success, it ran cool all day today, something it never did before in summer. It will need a gentle blow out from the front soon.

Thanks everyone for the help.

I will just list the radiator gasket part numbers here for reference.

Starting at the top, from top tank to adapter plate is 6n4950
From top adapter plate to top header is 6N4949
From bottom header to bottom adapter plate is 6N4956
And from bottom adapter plate to bottom tank is 6N4955

If you use it during day light hours only, could put tint film on the windows

 

[.RC.]

The problem with tinting is when it gets dust on it, you would not be able to see out. It is bad enough now in the afternoon seeing out into a shadowed area, you cannot see the ground and do not know if there is a precipice ahead of you or not. Added to vision problems 50% of the glass has been replaced by perspex.

Probably why some of the old timber rigs Scrubpuller posted pictures of had goofy sunshades on them. Most were open canopy, but I'm sure it helped a bunch.

Sure wish I knew how that old bugger was doing.

Might as well post these pics here that I took today.

Shimmy, I miss him too. As far as those sunshades or canopys, maybe Oz or Tones could say. The only explanation I could find on the 'net says those are to keep the snakes in the trees out of your lap. Fcuk that!!!

 

[Pony]

You mean something like this?
Just an old style scrub canopy to keep the trees and limbs out of your lap.
Round on top so the limbs will fall off and not sit up there.
Although the newer style is square, so flat on top, easier to make I guess, but rubbish would accumulate on top I imagine.
Don't own and never used the newer ones so can't say for sure.
The one in the picture is a little big for the baby dozer, but I got it for almost nothing, bit of fabrication and it doesn't fit to badly.

Bloody hell it’s green there…. I thought it was looking good here but that is a whole other level!! Nice view too.
Glad you got your heating problems sorted, I’ve been following your progress.
