so i've drained the coolant refilled and bled per the instructions and i am still overheating. however, i am 99% sure all the air is out, i got coolant coming out of the bleed plug when filling and the top radiator hose is hot when it comes up to temperature. but there is still no heat coming out! you can drive it for about a mile or so and then all of a sudden it just goes into the red zone. i changed the thermostat also during this repair so it seems like that should be fine. any ideas what could be causing this? i don't have any symptoms of a blown head gasket so i'm hoping this is just something small that i need to figure out. any help would be appreciated.

 

I think I'm going to start re-quoting the relevant parts of people's posts to give them their own answers.

 

ok well look i came here for help not smart *** comments. i'm sure you guys get tired of people asking questions to which the answers may be obvious to you but isn't this the whole point of the forum? to help others that may have less knowledge? so what are you telling me oh wise ones?

 

It's not the coolant....
Have you done a block test to check for combustion gasses in the coolant?

 

if i knew the answer to this i probably wouldn't have created this thread.

 

no i have not. i'm not sure i have the tools/equipment to do that

 

You can buy a test kit at an auto store, or take it to a shop to run the test. Basically it just tests for signs of combustion gasses in your coolant.
Your symptoms point to blown head gasket.

Were you just trying to replace your coolant or were you fixing a problem?

 

Sorry you got hat sort of a crappy reply, believe me he won't do that again.
As for your issue, if you want, send me your number and I'll call you back and walk you thru your trucks issues.

 

it all started with a bad water pump. it overheated and i had to have it towed home. i replaced the water pump, thermostat. also changed the oil because it was a little cooked. and while i was in there changed the plugs and wires . my oil pressure light was coming on for a little bit but since i changed the oil i havent had a problem with that so i'm guessing that was just a result of the cooked oil. i went back in with shell rotella t 15w-40 and a landrover filter.
