EGT temps?

[INTERNATIONALPOWER]

I had a question as to what temps are you guys seeing on your egt gauges when running empty and loaded?

I currently run around 600 degrees empty at 55 mph and around 800 up hills with a loaded trailer at 55 mph.

I have an 06 f-250 fx4 lariat with 5 inch cat back with the cat gutted.

Those numbers seem a little low, is your pyro pre or post turbo?

its tapped into my drivers side exhaust mainfold.

I run 700-800 empty and 1000-1100 loaded (6500lb trailer) up a fairly steep grade in stock, 58mph.

ok because that makes sense. I ask because at around 1000 degrees my stock temp gauge rises rapidly and the check temp indicator on the dash comes on. Then when i back out of it the gauge comes back down and bounces from normal to mid-way high.

But what suprises me is that when you open the hood no coolant is in the degass bottle and when you turn the cap the coolant comes up but is boiling inside of the bottle.

Well I had a mechanic at our shop do a test of the air coming out of the coolant bottle and it turned from the blue to a green in the test tube that measures the air, which means that I have exhaust gases in my coolant. Which is no good.

EGR valve would be my guess.

They just replaced my egr cooler in April. I guess it is possible that they could of went bad in 4 months.

But would that casue the coolant temp gauge to rise and vent the coolant out the degas bottle?

Yep, either the EGR or a blown HG.

Like 95 said, either EGR cooler, or blown Headgasket.
