OIL/WATER TEMP

[Chamberpains]

We're not being negative. Your getting the normal amount of ball busting and sideways humor that comes with the trucking industry. Don't take it to hard. Your in good hands. I'm here to learn and help and have a little fun doing it.

Now as far as us not knowing your situation, well your wrong on that. When I said I went back and reread all your posts. That's exactly what I did.
You've already stated that your a company driver that you pull the heaviest loads for the company so your boss turned your truck up, and being in Hawaii there only 1 guy doing tunes back in 4/2016, you drive a 2007 or 2005 (you've asked very similar overheating questions and used both years) Kenworth T800 with a cm870 that was orginally 475hp and is now "turnt up" to 550hp by your mechanic, you drive other trucks but this one is your main truck, your've replaced the coolant level sensor (4/16), you used to run with the EGR unplugged (4/16), the head was replaced on the last long block in the truck, you swapped your ECM 550hp tune with an ECM off a similar truck with 475hp and your coolant levels(I'm assuming coolant temps) and Idle were correct and ran smooth again (hmm I wonder if this can point to having the correct ECM cal on the engine might fix things), The ECM you currently have is not the original 1, When you changed the Thermostats (9/16) you stated you get really high temps from standing in the throttle and they back off when you down shift and back the torque off(pulling a hill really hard will make high temps especially in warm Hawaii), (4/17) you stated the water jacket cracked and you were looking for a long block, (10/17) you asked if a bad tune can cause overheating (looks like you were looking in the same direction then that we are now) (10/17) your '05 is having high oil temps on hard pulls, (11/17) someone gave shitty advise to run without oil thermostat (hopefully you didn't) And that brings us to our current conversation with a new long block and a bunch of new parts.

Now where I might be getting some of this wrong is that you may be talking about different vehicles. But you've been asking in one way or another about high oil and coolant temps on these vehicles for 2 years.

With the above information and knowing someone altered the ECM (whether correct or not, We do not know) all we can do is start with your truck having a good calibration that is supposed to be on it. That way we know that the components of the truck are at least getting told to act properly. After we know that's correct then we can go down the laundry list of causes for High oil/coolant temps on a hard pull.

I had to assume you were trolling in someway because almost every one of your threads you yourself or Rawze or someone else has suggested to have your cal. checked and you never confirmed what it was checked or that it is correct. Just that it was turnt up to 550.

So go get us that current Calibration # in the ECM and the CPL # off the new long block (just incase they switched the CPL on the long block and still used your ECM)
