i just bought this truck but ive 4 just like it and i know my way around them to a certain point... the man said it had overheating problems i put a new radiator hose in on it and topped off fluids.. the batteries were low so we pull started it... runs rough wont idle and overheats quick... within 2 min.... radiator and hoses had a ton of pressure... possibly head gaskets??

 

i'd say headgaskets. look for fluids runnin down the side of the block to tell you the definite one. you might not have any but i had oil all down the side on my 6.9

 

Thermostat stuck? Dunno.

 

with all the pressure i'd assume hg's but you can always check the thermostat. doesnt hurt to check

 

if it builds right away it is headgasket or could be cavitated.

 

can you explain cavitated for me man? i didnt grasp the concept and i cant add to the conversation if i dont grasp the concept

 

Cavitation Article


read on up. it sucks.

 

you couldn't just say when's the last time you changed your coolant? i would've known what you were getting at right away. that article almost made me put my head through my wall

 

one reason i will never own a 7.3. they are prone for it.

 

is that because of the thinner cylinder walls? btw i got my 6.9 on my engine stand
