slight coolant loss

[kaptain howdie]

have an 09 f350 with 14k. since my last oil change 6 months ago i have been keeping an eye on the level of coolant in the reservoir. at the beginning of the summer it was at the level at the bottom of "range", now when i checked it on level ground it is slightly below. I have not noticed any leaks since due to paranoia i look under the truck frequently.

is this normal and or something i need to be worried about?

i`m going in for an oil change soon, so I want to be prepared just in case i get "its completely normal" speech.

Just wait, that same thing was happening to me, next thing you know the radiator had a small drip on the driverside bottom you could see visiable residew on the frame rail.

Took it to the dealer to have it replaced under warranty,alond with the upper hose and tee stats.

taking mine in to have it looked at for the same reason...mine has gone down about an inch over about 5k miles or so.

Mine changes 1"-2" depending on coolant temperature, and raises when you unscrew the cap (after shut down) and let the pressure off.

Mine was low the other day, noticed a lil on the bottom....dealer pressure tested and said upper was leaking as well. Replaced upper and lower.
