next time you need parts for your vehicle, think of 1AAuto.com. Thanks. In this video, we're going to show you how
to replace a thermostat housing on this 2003 Mercury Mountaineer. The items that you need for this are a new
thermostat housing for 1AAuto.com, a 10mm and 11mm socket and ratchet, a pair of pliers,
a flat-blade screwdriver, a vacuum and wire brush, and a torque wrench. Start off by loosening up this 8mm bolt on
your negative batter cable and pulling the negative battery cable free and then remove
these 11mm nuts. Lift the engine cover up and off and, open
up the clip on the back, and pull the hose free. Using a pair of pliers, just push the teeth
together on this hose clamp and slide it back, and then twist that hose free, and just set
that hose aside. Now, remove these two 10mm bolts. To help you get the other bolt out, it's easier
if you just remove this 10mm nut right here and pull that wire out of the way. That bolt pulls right up and out. You just tap the housing while lifting up
on it and it will pull free. Pry out this little O-ring with a flat-blade
screwdriver. Take you new O-ring and push it into place. Take your housing and push it down into place. Then, replace those two 10mm bolts and tighten
them up. Torque those two 10mm bolts to 19 foot-pounds,
and then replace that wire and replace the 10mm nut and just tighten it up. Take this hose and push it back into place,
and then using your pair of pliers, just slide that hose clamp back up in place. If it doesn't pop open on its own, use a flat-blade
screwdriver to just hit the tab separately. Take your cover and push it back down into
place, making sure those clips push back in, and replace those two 11mm nuts and tighten
them up. Then, push that hose back into the clip and
close the clip. Reconnect your negative battery cable and
tighten it back up. Then, you're all set. Any time you so any service to the cooling
system, you want to make sure you add radiator fluid. For this Ford Motor product, you need to use
the gold style fluid or make sure it's compatible. This is a cold fill line. You want to be within this range. Make sure the engine is cool when you're filling
it. If you've done extensive service or drained
a lot out of it, you'll want to do this and start up your engine, run it, let it cool
down, and you'll probably do it a few times before you add back all the coolant in. Any time you service your cooling system,
refill it and recheck it a few times the first few times you drive it. We hope this video helps you out. Brought to you by www.1AAuto.com, your source
