well i live in So. Cal and when i wake up in the morning my truck will go from about 160-210+ in about 15 min, i am not pushing it at all. truck is pretty much stock(supercharger on its way as soon as check clears), i have an aftermarket thermostate in it 160, k&n intake, some other small add ons,not sure what to do truck is not overheating at all truck has a 120,000+ miles on it. what to do? time to change thermostate? radiator flush? wtf!! its pissing me off!

 

im taking it cools off when u drive? low coolant, air pocket, faulty tstat, obstructions blocking the radiator? leaves, bags, etc., try burping the sytem to get all the air out

 

x2. After my cam swap my truck got up in the 240 degree range because I had a pocket of air, but opening up the coolant tank and "burping" it fixed it.

I'd also check out the t-stat as mentioned above.

Your stock clutch fan might be out as well, never heard of it happening on the newer trucks, but anything is possible

 

Ive seen it happen on the OBS trucks..
We put my Clutch on his truck and it works amazingly better than his stocker.

But check for air pockets, a new Tstat wouldnt hurt.. If someone was close to ya, they could scan it and see what the exact temps are.

 

Can you borrow an infrared temp gun and check the water neck or coolant hose neck?

Might tell on your gauge accuracy/inaccuracy!

does it jump around sparattically? if it does, this is what just happened to me, the ECT sensor in the head went bad.
Log it and see what the computer is saying, if its erratic thats the problem, just the sensor

 

the temp gun is at home if i can find it. i was thinking that when i was driving home, as for burping the system i will probably do it when i go on my lunch break, i have already ordered another t-stat. thanks for the help guys i will let you know next week i am headed for a long vacation!

 

how high dose it get? mine has allways run at about 210.
