Diesel cooling options and ideas

[mrmo]

So removing noise insulation (EGR side) and the corner pieces at rear of the hood didnt do anything? im wondering if each little thing done will help as this continues. Im considering doing the oil cooler w fan, removed the engine plastic cover first day i had it. May go for the hood vents mentioned, although cutting into a new vehicle hood is daunting

All I can say is the way I did it didn’t seem to affect temperatures. But all I really did was open an area hoping to allow air to escape. I didn’t really do anything to create a low pressure area right at the opening, for all I know doing what I did could have created more pressure pushing into the engine bay.
It seems likely to me that if we can create some low pressure areas using louvers or something else we could draw air out which should help more air flow through the cooling stack.
I suspect to really do good testing it’s going to take more equipment and knowledge than I have. I think I need someway to measure under hood pressures. The Banks Data Monster has the capability to add sensors if I had the module and the sensors. Looks like it could be done but just the module to hook the sensors to is over $300 not to mention the sensors.

anyone tried the inner fender wells w louvers or other openings? thats gotta let a good it of heat out, like hot air from the radiator being pulled into the compartment. maybe some holesaw cuts, 4 holes @ 2-3"

I don’t have my gladiator yet so I can’t check but what is the stock radiator made out of? Aluminum and composite? Radiators can be fabricated that have the same physical dimensions as the oem but using better thermal materials and different fin density to get +30% more cooling over oem. I have sent in oem radiators to have the mounting locations cloned into a custom radiator for bolt in.

There would probably be some advantage in ditching the oem fan and used shrouded Spal fans.

This is a really long thread.

Has anyone tried using an intercooler water sprayer on the radiator yet? I wonder how effective that would be.

No, but I have given it some thought. I used to have water/alcohol injection on my tool truck many years ago, and I don’t think it would be too hard to fab something up. I ordered the aux switches on my Gladiator and could use one of those. You’d need a tank and some kind of spray bar.

I have everything to do this. But. I haven’t figured out where to put the tank. Also I realize I need ~5 gallons.

mom going to a full-size spare under the bed cover and that will free up space underneath for a pancake tank or something of the sort.

I’ve done a ton to reduce under hood heat. All of it helps keep IAT’s down when at low speed and under hood temps way way down. I can touch the aluminum afe intercooler tubes at a stop and the top of the radiator etc.

That said nothing will help the issue of the oil temps spiking under full boost with high ambient temps. The oil cooler can’t shed enough btus to keep up with the demand of the engine. A larger radiator will help with recover once you crest the hill but it’s not going to stop the spike. To stop the spike we need active full flow oil cooling out in the airflow.

Just curious- anyone with a GDE tune? Or better yet Delete still experiencing the same heat issues??

I don't own a trailer so not the best comparison but I've never experienced an overheat yet. Even overloaded through the mountains with tools and gear, my brakes seemed to be the weak link not heat.

Factory exhaust has been sitting in the basement since 5k.

How high are your EGTs getting?

Wonder if the reduced restriction on the exhaust is funneling that heat away from the EGR coolers and keeping her running cooler under load.

Please state what you have done to your exhaust for conversation context.

heat issues during the summer. at high altitude i can do the best of 65 mph. anything else and i start to overheat.
