so last weekend i decided to check collant and it was a light brown.
so i dumped it out most of it was green except what was in the resivor.
ifill it up and checked it today and its the same.
someone told me it was oil but doubt it since collant level hasnt gone up or down and oil looks fine .but also grante that the collant in the truck was 4yrs old. truck only has 75k so im not sre what it might be mabey flush it out. trucks never gave me anyother problems other than the starter.

 

Its rust coming lose out of your cooling system a flush is recomended , if you let it rum dirty line that for a long period of time out will eat at your water pump blades causing over heating problems in the future

 

i guess i have to look into it next weekend truck runs fine.

 

Yea mine did to, until i.had the over heating issues, id say check.you lower n upper radiator hoses to make sure they are in good shape m not crunchy, had to replacey lower hose was pretty easy actually

 

Yeah definitely flush it. The reason it turned brown again is because some is trapped in the block when you turn off the truck.

What i did was run water in it several times, draining it every 5 or so minutes.

 

yeah thanks but i decided to stick one of thosse small cameras with a light and the inner transmition cooler raditor is cracked so im just going to replace the radiator and flush out the whole system

 

update so ifinally changed out the raditor wasnt to bad just 4 bolts and had to take off the stupid plastic cover thing its been a wk and coolant stayed green so ithink this problems done with
