Prh0w1317 Posted July 29, 2019 Share Posted July 29, 2019 Hello, I've been getting some high mileage maintenance done on my girlfriend's 2010 Ford Fusion 3.0L V6 and am realizing this year and engine size seems to be slightly unique than other/older year engines of same size. Does anyone know where the coolant bleeder screw is located? I have the Haynes mechanic manual as a guide and it says it should be located on top of water pump or housing and that it should be a hex nut. Does this sound right? I'm still having trouble spotting it so I ended up doing the coolant change/flush without finding that valve. I'm thinking this matters because I only seemed to drain about 1/3 to 1/2 of what the coolant capacity should be. I hope I didn't introduce a bunch of air into the system because of this. Any help would be greatly appreciated. Especially if you could take a photo and point or circle where it is this valve is. I attached a image of what the under the hood looks like for this engine. It's a generic photo I found on Google search. 0 Quote Link to comment Share on other sites More sharing options...
Prh0w1317 Posted August 2, 2019 Author Share Posted August 2, 2019 Found it! It's actually pointed out quite clearly in the owners manual. You have to take the air intake out ( the flexible intake that connects to the throttle body) to access the hex nut that sits on top of the water pump housing. It faces up and is easy to get to. It takes a 1/4" Allen wrench to get the valve loose. It took a bit of force to get it loose, I had to hammer my Allen wrench a few times to loosen it. So, regarding how it helped draining coolant out... There was no difference than before. I can only seem to drain a little more than 1/3 of the coolant out. The rest must be trapped deeper in the cooling system lines. I spoke with someone at the Ford parts dealership and they said when they drain coolant that suck it out. Not sure if that's true but maybe that would get more fluid out. Anyone know how to drain more coolant out? 0 Quote Link to comment Share on other sites More sharing options...
rufixed Posted August 8, 2019 Share Posted August 8, 2019 Glad you found the bleeder valve location. I managed to use a hex socket and a good ratchet extension to preform the bleeding operation without removing the intake. After swapping the engine in my 2011 3.0L fusion, I had lots of air in the coolant lines, leading to serious overheating. to bleed the coolant, I loosened the bolt on the bleeder valve while running the engine, and watched the air bubble out of the valve. Anyone got any pointers on a better technique ? 0 Quote Link to comment Share on other sites More sharing options...
