HOLY HELP!

if its not one thing its another with my truck.

so today im cruisin 15 miles from work to town. engine oil temp starts goin up as normal and by mile 10 im at 222, now i know thats a lot BUT i usually run about 216 bc the digital gauge is a little off but when i get to the bank im at 238 so i know somethings wrong. i drive across the road to my moms office and chill for an hour and let it cool down. i make it home at 233 (7 miles). i sprayed it off with water and was pretty happy with myself getting it to 135, i figured that with it being 105 degrees outside it was just running hot thats why i wasnt freaking out.

3 or 4 hours later i go to leave but i wanted to check coolant NONE. filled it with water and tried to see a radiator leak (didnt see one) and the water held so i figured id run to the store and get some coolant. didnt make it down my road. i took my radiator out and all the water was this nasty rust color too.

now im stuck with my radiator pulled out and tested good, no coolant and no wheels....where do i go from here? thermostat has been the case 5x before but why would it continuously go up if that is the case? blown heads/ gasket?

Do you have any water in your oil?? Could be a cracked radiator allowing water in places it shouldn't be going.

i took my radiator off and taped the bottom up and filled it with water and didnt get a leak. i did that on a 6.0 2 weeks ago and it worked like a charm but i didnt find anything but now ive got people telling me that i should use some kind of a compression test on it?

Yes you need to do a compression test on your radiator since it is under pressure when the truck is running and heated up. You may not be able to force water through a crack until there's pressure applied. Which is why this test is needed.
