Overheating

[luke45]

Im having an overheating issue. Whenever I have a load on the truck, i can go down hill and flat all day no issues. Whenever I start climbing a hill and its lugging low rpm, High boost My coolant level climbs rapidly, and if i dont let up it climbs and climbs until my gauge is pegged, and my alarm is going off on the cts, also losing coolant. The truck has egr delete, oil cooler, arp head studs, and thats about it. What could be causing this? I hope that it wouldnt be a head gasket because i just did the arp studs last year...with new everything. Anyone know something i don't?

Do you hear the fan kick on ever?? It should come on hard about 215-220 and its very loud.

Check the lower hose, might be collapsing.

What gaskets did you use for the head gaskets and studs?

Now that i think of it, the fan doesnt come on...

Also the lower hose on the radiator?

I had that problem, was told to check it and sure enough. Under load, with an older or weaker hose, they tend to collapse, kinda like when you burp it, replaced the hose and problem too.

Did you leave the egr plugged in after the delete, on certain strategy unplugging the egr won't allow the fan to come on 100%. What tune are you pulling with? If it is a race tune that could also be the problem, what are the egts doing when it's overheating?

Sounds like blown head gaskets.
