It has been 45k and I decided to go ahead and change the coolant. I drained all the nasty stuff into a container, and now I wanna flush it. The problem is...where to add the water/flush/new radiator fluid. I have a 97 4.6 and I am half way through the job. For some reason I cannot seem to find the radiator cap. I know where the resverve is, but it does not seem to want to flow into the radiator. I would turn the truck on and doit, but I am afraid oh over heating the engine. Please post ASAP....

Regards,
Ron

 

yeah thats it thats where the water and coolant goes pour it in and start the engine then add more wore u know the 50/50 mixture of coolant in the radiator resvoiur tank

 

I tried that too, and it seems to go in so slow that I thought surely not. Have you done this before?

Ron

 

im a ford tech i do it about everday lol

 

about how long should it take to completely filler back up?

 

Dont forget to turn your heater all the way to hot so the new antifreeze will run through your heater core as you fill it up.

 

I am gonna go try it...thanks for the fast updates...

Ron

 

just run it to normal operating temp and check the level when done

 

I did the flush like 10k miles ago and everything is working fine. I did follow the Haynes manual instructions for this task and it help me a lot.
