4in exhaust, edge CS, Airade filter.

Highway temp 190's, today was 83f saw 210 on temps in town.

Yesterday was about 85f was seeing 230's??

 

Mike what do you think about the water pump? I heard the fins just fall apart...

 

Is there a way to check??? Would air bubble cause?

 

Quite a few things could be causing it.

Can you hear your fan coming on at all?

These waterpumps suck, the plastic fins on the impeller do crack and don't move much coolant after that. Blown headgaskets could also do this, with cylinder pressure constantly aerating the coolant, not letting it do it's job.

 

Not using any coolant, level same, no white smoke, runs clean,

Checked fan first it was turning, coolant looks clean?

 

It's turning all the time, but doesn't mean the fan clutch is operating correctly. With the way it's turning now you can probably stop it with your hand. When it actually gets going, you can HEAR it. It will be really loud. Either way, the fan would cool it down some, but it shouldn't really be getting that hot in the first place.

 

My guess would be water pump, if the clutch is engaging on the fan? Bc he's not losing coolant and no smoke... So the coolant isn't flowing enought to circulate it...

What have you been checking your temps with? Try checking with a scanner?

 

Am getting readings off edge cs, I. Can feel top hose on rad and feel coolantgoing through?

 

If your oil cooler temps are within check as you say, sounds like you're going to have to dig into it and see what's wrong. I would pull the thermostat and just replace it, and inspect the water pump. bulletproofdiesel just released an upgrade for our trucks, billet aluminum impeller water pumps!

 

OK, will look into.
Just bought truck few months ago, did oil change and fuel filters. Talk to dealer today, no codes, but temp was under 200? It was a one owner truck and they did all maitance told me coolant changed 40,000km ago. But was coming due on trans. flush?
I will listen for that fan to next time, but I am sure I heard it and itwas loud.
