Locate the hose that goes to the top of the radiator that hose leads to the thermostat, remove the hose, at the engine there is a water neck be careful as it is rather old and may have rust and is prone to break, remove the 2 screws that hold it in place, remove the water neck (thermostat housing) and remove the old termostat, scrap the housing and engine block from old gasket and silicone, add silicone to the housing and place thermostat in housing in circular ridge then place the gasket over the thermostat apply more silicon over the gasket and spread evenly, allow the silicone to set for a couple of mins and then put the housing back with the engine then connect the hose back and your all set; remember the thermostat part that goes into the engine should be the part with the spring, hope that helps

How do you change the thermastat on the 2005 ford explorer sport trac


  1. 1 Drain the coolant from your Explorer into an adequate container by opening the drain plug at the bottom of the radiator. Save the coolant for reuse if it is relatively new and clean.
  2. 2 Remove the negative battery cable from the battery if your Explorer has a 2.9-, 3.0-, 4.0- or 5.0-liter engine. This step is not necessary for 2.3- and 2.5-liter engines.
  3. 3 Follow the upper radiator hose to the front driver's side of the intake manifold, where it meets the engine. This is where the thermostat housing on your Ford Explorer is located. If necessary, remove the air cleaner duct for easy access to the housing.
  4. 4 Loosen the clip on the end of the radiator hose and pull the hose off the thermostat housing. Use a 10mm wrench or socket to remove the two retaining bolts on the thermostat housing cover. Remove the cover.
  5. 5 Note the position of the thermostat before removal. Pull out the old thermostat. Seat the new thermostat inside the housing in the same position as the old one, spring-side facing into the engine. Install new gasket over the thermostat.
  6. 6 Reattach the thermostat housing cover and the radiator hose. Reinstall the air cleaner duct if removed earlier. Fill the radiator with reserve or new coolant. Start your Explorer and run with the heater blowing until the engine gets warm. Check for leaks.

you may need to check/raise the quality of the parts you are buying. You dont say what engine you have? if the radiator cap is incorrect or bad, it may have too much pressure on the cooling system.

Overheating, 1994 ford explorer has been running hot and blew a hose today


When was the last time you had your thermostat changed . Also is the fan belt in good condition and turning properly everything. Also ensure the water pump is working properly while the engine is cold start vehicle, remove the cap to your radiator let the vehicle warm-up and see if the water is circulating if so then you can rule that out... If not then your water pump is probably bad.
I hope this helps and good luck.

91 explorer heater not blowing air


The blower motor is located under the hood on the passengers side next to the hood hinge on the firewall. But, check your blower motor resistor first. The resistor is usually the trouble maker. It is located next to the blower motor. It should have 2 screws holding it onto the heater housing. Also an electrical connector. I sincerely hope that this will get it working again. Best wishes to ya.
