Anyone have any troubles with 2008 3l Common Rail not running well on hot days? Seems to lacking power big time.

They do love the cooler air thats for sure.
Is the intercooler in good nick? No bent fins, obstructions, no leaks etc?
Air filter Ok?
MAF sensor clean?
If it is getting as much air as you can give it then not much more you can do

Check the radiator for blockages.
You may still have flowing water in the radiator but it still may be blocked.

The intercooler does look ok. Not sure if it has any leaks (how can you tell?). I have recently cleaned the MAF sensor and put new air filter, oil filter & oil change. To me it doesn't seem the engine overheats (I am only going off original temp gauge). Since I have had it, it hates the hot weather. Could it just be it doesn't like the hot air? Or could the turbo start to expand and not be as efficient? Would an extra bonnet scoop work to let more air in over the engine? I am getting a quote for a engine cooling flush tomorrow. I will let you know how much they ask. As I am going on a trip next week hopefully I can get it done, and it helps. Will let you know. What is the GOAT syndrome?
Its a long long story but search for overheating 2010 model..
You may find dust and mud has settled along the bottom of your radiator causing a partial block.
Whip down the car wash and gently soak the bottom between the fins. Is your fan working correctly??.
lots of if and buts with over heating, do one thing at a time that way you'll know what it is.
How About a new OE thermostat.

Mine noticeably lost power on hot days, I changed the scoop and noticed a big difference straight away.
Still had less power than cool days but that's expected.

You can tell if your IC is no good by an oily dirty appearance.
May need to remove engine cover to check, check hoses at the same time

He is not overheating. He is not making as much power on hot days.Originally Posted by threedogs
Cool weather is better for turbos, but the difference should not be that big.
I will give the radiator a wash. Not sure about fan. Will check that out 2. Should it be on all the time? I am sure the Intercooler is ok. What sort of scoop did you put on your Patrol?
The difference will be noticeable if it's hot enough. I can notice the difference in mine between driving in the middle of the day and the middle of the night. It will less noticeable on less boost as I am running 25psi. I would get your intercooler pressure tested just to rule it out but it is very common for them to leak.
