I had to remove my lite bar, ran accross the center of the grill with 4 lites when the out side temp got up into the 95's, made about 10 deg diff. There is an article at the dieselstop.com/data/500/28385fan_test_2-med. for checking the fan.
first post and a question

mmm.. you think so? well i installed the lights soon after the jasper was installed but i do remember the day i went to pic up the truck (almost 2 years ago) the fender was hot at the time i was looking at the freshly installed engine, i did ask wy and the "mechanic" said it was bc the truck was runing for some hours. After this i never knew if it was hot or not until i got the new gauge other than the time when i lean against the fender or some area around the engine, i did notice before the new gauge that every time i was on the highway with the ac ON it will got from almost upstraight to upstraight and some more. I have had ideas from a lot of people some say 230 is too much (on highway i run 215-220 with no effort) and some say 240 is too much. I just know that when i was driving back from the Rally Charlie's truck was not hot pulling a 5th and mine was, and you guys know i dont have a 5th to pull.
I will provably clean the condenser in front of the radiator again with water and change the fan clutch, even though it is runing most of the time i think.

Based on his temps at idle, I can't see the lights being a factor. He hits 200 just sitting still. 
EZ, can you put your hand on the lower radiator hose? On my truck, it is almost cool. Seems to me it has to be either the radiator, or the coolant is not flowing at the right rate. I wonder if there is a chance your water pump is the wrong one, or turning backwards?

no i just checked and no i dont think there is another way with this type of belt. also checked the condenser and even tough is not super clean it is definetly not filthily dirty.

Is there a way to check the flow?
I did a Google search and came up with this:
Tools needed: Flat head screwdriver or nut driver, ratchet and socket, possibly a scraper and rag if you replace the thermostat.
Time needed: 25 minutes
Notes and Precautions: Although you will need to view the fluid in the radiatior with the cap removed, never remove the cap once the vehicle is started. Remove the radiator cap only when the vehicle is cold.
Although many things can cause overheating, checking the circulation at the water pump and thermostat can often lead you to the source of your problems
Check your Circulation If you've heard the the noisy groans of the water pump before your overheating problem began, you can almost bet it is the culprit. A noisy water pump can be checked by removing the fan belt that drives it and turning on the engine. If the noise is no longer present, your water pump is on its last leg.
Even if you have not heard anything, it's still a good idea to check your circulation. The easiest check is to start up your vehicle with the radiator cap removed. As your engine heats up, the thermostat should open and you'll immediately notice the flow of fluid through the radiator. If your vehicle overheats and you have no fluid moving through the radiator, you definitely have a circulation problem. (If you have circulation but are still overheating, check our Overheating Quick Fixes here.)
After you let the car cool down, you need to determine whether your thermostat or pump is at fault.
Testing the thermostat will enable you to determine what is the root cause of your problem. To test it, remove it from the vehicle and place it in a pan of water. (If you need help removing the thermostat visit Change Your Thermostat.) Check its specs in a Chiltons or service manual and begin heating the water. Note the temperature it opens and check it against the specs. If it opens late, partially, or not at all, it is most likely the cause of your problem.
If the thermostat checks out, but you have no flow to the radiator your water pump is bad. Unfortunately, there's not too much you can do except replace it.
If you need more heating and cooling advice and tips, check the Jonko Engine Repair Forum.

I did run the engine with the cap off the rad and noticed some of the coolant coming of the rad and drop on the ground then lower and then drop again. also open the cap while runing (not too long) and still the same thing only this time it droped more coolant on the ground. I use prestone 50/50 with the dca4. I dont feel like replacing also the water pump but if testing it shows it is low flow it will be most likely the problem.
Thank you, Exekiel.

Thank you Mel,
I take that as high praise from the master of good posts!
Of course all I did was copy someone elses good info, so I can't really take much credit.
Exekiel.
When I get some time. I should stop by your place. And we can compare, flow rate and tempatures side by side with both of our trucks. Anyone have a idea of the best thermometer to use to test the coolant temp? I am kind of drawing a blank on that one. Hmnn, I could call KennyD and ses if I can borrow his "heat gun". I would't mind having one. But they be pretty pricey.
EZ, let me know when you want me to come by.

Charlie you are welcome any time, how about this weekend? I talked with Mel yesterday and he proposed me to check the flow to see if the pump is moving the right way. I'll call you to set a time 
Now thinking about it, it would be something if we find the problem was the pump
i bet Jasper will agree to more stuff to be replaced on the engine if they dont want me calling the bbb to tell them they are not serious enough to build an idi engine

Yea I think Jasper is giving you the shaft.
Well I am moving dirt Sat afternoon and Sunday in Burtonsville near Silver Spring Md. My truck will be hooked up to my Gosseneck trailer. So how bout we meet on my Job Site Sat. Morn. Can you bring the thermometer?
I will contact you with directions and address. "EZ" to get to.

Just a thought EZ, I spoke with Ken about overheating problems in general, and said that on a rebuilt engine, some head gaskets came with an insert that should not be installed. If it is installed that will cause low coolant flow, and lead to overheating. Has anyone else heard of this?
Just something to consider, I will be heading out to see him tomorrow morning, If I think of it I will pick his brain about it again.
Later,
Darrin

Hey Darin,
As we are running out of posibilites. That is a good find. We will try to compare flow rate and temp between EZ and my truck under the same conditions. I hate to see EZ having to continually pour money into this problem, without a solution.

That is another possibility, yesterday i turned on the engine with the rad cap off and i watched it for 30 minutes to see the coolant go up and down, some times it overflows a bit. I will also check Charlie's water pump and see if they are at least similar with mine. about the head gasket well you got me there, this engine is NOT GOOD, i bought it from Jasper and my warranty dies on a few months if it is for me i ask them to give me another one but i don't think they will. Do you know wath type of head gasket are those? any way to verify? so I can call them and ask.
Than you, Exekiel.

Let us know how the comparison goes.
