i talked to a couple friends of mine that are in the mechanic business, they both leaned toward the fact that because the fluid changed to a lighter blue color it could still be the head gasket issue. so i'm going to replace both along with the water pump, guides, tensioner and head bolts.

i tried the combustion gas leak test. the blue fluid only turned a lighter shade of blue. not green/yellow color at all. i tried this three times. the last time i tried for over 19 minutes, with the tube in the coolant overflow. the coolant level (cold) started out around the middle of the overflow container. as the engine warmed the level started to come up so that it was close to the bottom of the tube/fluid, i'm pretty sure that contaminated the tube, so i dumped that out and started again. each time i did this, the blue fluid only changed to that lighter shade of blue, then at the end i had a bit of coolant coming out the top of the overflow. so i'm going to guess there's no headgasket issue..........but i've been wrong before! thoughts?? thanks Brian

Hi everyone, i'm about to get into replacing the water pump, but i thought i'd ask before i start tearing into it. 08 ford edge limited, 160k, my neice was driving when engine started to overheat, was leaking fluid from passenger side, i'm guessing from the overflow container fluid was hot with air bubbles being pushed out. (that's the description she gave me ). her grampa changed thermostat but it sounds like coolant is still leaking out the overflow. this sound like a waterpump issue? thanks Brian
