Super easy package to install...
1. Disconnect Battery (always remove the negitive cable first), Remove battery. 10mm for both terminals and for the batt hold down.
2. Remove battery tray, 13mm socket will work. (3) Bolts
3. Remove cap from coolant overflow and drain radiator via the small round black drain plug on the drivers side of radiator. Close radiator drain port after draining complete.
4. Remove all the hoses from the Thermostat housing neck. Ford has hose clamps that are designed to hold them self open, you will either love them or hate them.
5. Remove the (3) bolts holding the thermostat housing to the cylinder head, a 10mm socket and or wrench will work. Take care not to damage the metal pipes running in front of the two upper bolts.
6. Clean the aluminum mating surface on the head to prepare for the new housing. I used a spray of brake cleaner, then a 3m Scotch/Scuff Pad then another shot of brake cleaner... Looked brand new in 30 seconds.
7. Install new housing with (3) bolts previously removed.
Connect all hoses to the housing except the rear most hose. Now fill the overflow tank with new coolant until it leaks from the rear port. Now install the hose. Fill the overflow bottle to MAX fill line and leave cap off.
8. Install battery tray and battery (install positive cable first then negitive).
Quick check to make sure there is no leaks.
9. Get in the car, turn the heat on the hottest setting, blower on high and vent from outside and start the car.
Run at aprox 2500 RPMs until the heat blows HOT and the engine fan cycles on and off. Make sure the car does not get hotter than normal operating range.
10. Turn engine off, check for leaks. Fill overflow container to MAX Fill line and install cap.
Clean yourself up.

      Comments about Dorman - OE Solutions Thermostat Housing and Outlet:

      Took about 45 minutes to install in a 2002 Ford Focus ZTS. I removed the battery and battery box first for easier access. After removing a few coolant lines it came out with 4 bolts. Comes with everything you need and worked great.

      Comments about Dorman - OE Solutions Thermostat Housing and Outlet:

      Removal of battery and tray were good tips to know in advance. I'd get the store hose clamps as the Ford ones are hard to work with. This is plastic so make sure you get the torques for the specific engine. I was surprised that they change from engine-to-engine (as listed in the Haynes book). I had the Zetec which called for 15 ft-lbs.

          Comments about Dorman - OE Solutions Thermostat Housing and Outlet:

          I previously posted a 5 star review for this product. After 6 months, the thermostat started sticking open, and I had to remove and replace the thermostat from the housing. Which of course meant draining the coolant again. Any time I saved installing this was wasted by having to do it all again. The new thermostat is a Motorcraft thermostat which will hopefully last longer.

            This is a complete replacement including gaskets and thermostat. If you were going to replace the thermostat anyway, buying this kit is a no-brainer. Save yourself some trouble and remove the battery box. This will give you easier access to the four hoses.

              The old housing had cracked on my 2003 zx3 and thus leaked coolant everywhere. This part was bought and fit right in after removing the old one. Pretty easy and fixed my leak.

                I found it easier to install if you remove the battery and battery tray. Then I didn't need to work from underneath the car.

                        It is a very easy job. In the reviews I posted a how to. You only need a few tools. Alldata calls for 1.0 hours and I suspect most of that is for the drain and refill procedure. It takes 20-30 min for a experinced mechanic.
