....is needed to re-fill the radiator after draining it to do efans and 160* thermostat? I have 2 gallons of 50/50 antifreeze but I want to make sure I'll have enough.

What did you need to drain it to do the efan's for? I don't remember draining mine for this. Maybe I'm just forgetting something.


Just keep dumping some in and "burping" the radiator hose to get the bubbles out, then fill the overflow tank to the appropriate line.

I don't think that the radiator has to be drained for efan install. I just threw the efans in with the staement because they will be done at the same time as the thermostat. I'm pretty much just going to drain the radaitor when I do the the thermostat to flush the fluid a bit. I have about 65k on the odo and don't know if it has been flushed. So, therefore, just need to know how fluid is needed to re-fill it when I'm done.
