SOURCE: diagram bypass heater cord on 2001 ford expedition eddie bauer

the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply

SOURCE: Bublling in the thermostat housing and very hot upper radiator hose

I recommend flushing the radiator thoroughly if not done recently. there seems to be some sort of blockage in the radiator at this time. if you get lots of metal fragments that are flushed out during this flush, i will then recommend a rebuild on the radiator or replacement of the radiator. make sure the cooling fans are cycling on time as well.

SOURCE: How to change a 2000 ford explorer bypass hose?

You have to remove the tensioner assembly, not just the tensioner pulley, but the whole assembly, in order to access the plastic bypass hose.
Be very careful, as these pipes get old, the plastic becomes brittle, and possibly the flange end will break off and remain in the block when you remove the pipe, check the block opening carefully to remove all of the remaining flange.
Also, be very careful when removing the lover pipe nipple into the engine block, if you try to pry the tensioner assembly off the block, you will probably snap off the machined nipple that locates into the block, Ask me how I know!!! Good Luck, it can be done but you need to move carefully and deliberately. (by the way, a rebuilt tensioner assembly costs about $80 US, the pipe is about $6. New tensioner assembly comes with the pipe)

You didn't specify which engine option but they are basically the same. There are 2 radiator hoses, one connects to the water pump (generally the lower hose) and the other connects to the thermostat housing (generally the top hose) The water pump is on the front of the engine and has a belt driven shaft, the thermostat housing is generally on the top or side of the engine block and has 2 or 3 bolts bolting it to the block and has no pulleys or belts attached.

How do I change the thermostat on a 1995 Ford Econoline van? Do I need to remove any brackets, belts, etc. to get to the thermostat? What tools do I need to remove the thermostat housing? I have limited...

I hope were talking about a Ford V8,
Just follow the top radistor hose back to the engine block.
There should be 2 "7/16" bolts and a housing.
You shouldn't have to remove the hose in most cases.
loosen the two bolts,MAKE SURE ENGINE IS COOL.
At the bottom of the housing is the thermostat it should be resting on the engine block.
remove and replace it with the new one in the same direction with the spring down in the engine block.
Male sure you remove all the old gasket and put in a new gasket.
If you need a gasket sealer "used with most fiber type gaskets" use the gasket sealer.
If it happens to be a rubber "O" ring type gasket, no sealer is required.
Good luck,Gary.
PS. please rate my answer.

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.

Replacing the thermostat on a 2000 ford explorer 4.0

  • Place the drain pan under the drain valve on the radiator. Loosen the drain valve and allow the radiator fluid to drain. If the drain pan is clean, you can reuse the antifreeze.

  • Loosen the hose clamps on the upper radiator hose using a socket, screwdriver or pliers, depending on the type of hose clamp on the hose. Pull the hose off the radiator and thermostat housing. If the air filter intake hose is in the way, loosen the clamps and remove the intake hose (on some engines).
  • Unbolt the two bolts in the thermostat housings. Pry the thermostat housing off the engine block. Pull the thermostat out of the housing. Remove the old gasket and discard. Slide the new thermostat into the housing the same way the old one came out. Install the new O-ring seal in the housing. Coat the housing with a thin layer of silicone gasket maker. Allow the gasket maker to dry.
  • Slide the bolts into the thermostat housing, then line the bolts up to the bolt holes on the block. Slide the housing down the bolts until it touches the block. Turn the bolts in by hand to get them started. Tighten the bolts to 89 inch-pounds of torque.
  • Reinstall the upper radiator hose. Tighten the radiator drain plug. Fill the cooling system. Start the engine with the radiator cap off. Allow the engine to come up to operating temperature. Look for leaks. Watch the level of the water in the radiator. Fill as needed

    How do I install a new thermostat?

    Explorer Thermostat LocationHere is advice for finding the thermostat:

    • Follow the upper radiator hose from the radiator to the engine and there is a housing that houses the thermostat. Take it off and when you reinstall the thermostsat, make sure the spring goes toward the engine.

    How to Change an Explorer Thermostat
    • 1. Remove the air cleaner air duct from the throttle body and air cleaner.
    • 2. Follow the upper radiator hose to the engine to locate the thermostat housing. The housing is located at the front of the intake manifold.
    • 3. Loosen the hose clamp, then detach the hose from the fitting. This can be difficult. If it's stuck, grasp with a pair of adjustable pliers and twist to break the seal. Then pull it off.
    • 4. Remove the bolts and detach the housing cover. Be prepared some coolant may leak out as the gasket seal is broken. Remove the thermostat.
    • 5. Install the new o-ring onto the thermostat (no gasket is needed) and install the thermostat into the intake manifold with the spring side pointing toward the engine.
    • 6. Make sure the air release valve is in the up 12 o'clock position. Install housing cover and bolts. Reattach the hose fitting and tighten the hose clamp. Fill the cooling system with a 50/50 mix of coolant and water, and burp the system.

    Were is the thermostat

    This is for a 5.0 didn't post your engine size:

    5.0L Engines
    1. Drain the cooling system.

    CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

    1. Disconnect the battery ground.
    2. Remove the upper radiator hose.
    Exploded view of the 5.0L engine thermostat and related components

    1. Remove the 2 thermostat housing attaching bolts.
    2. Loosen the bypass hose at the water pump.
    3. Remove the thermostat housing. You may have to tap it loose with a plastic mallet or your hand.
    To install:

    WARNING Do not use a sharp metal tool for scraping. Damage to the sealing surfaces could result and cause a leak.

    Align the air bleed hole on the thermostat with the notch in the housing, which is also the 12 o'clock position

    1. Clean all mating surfaces thoroughly.
    2. Position the thermostat in the housing making sure that the air release valve is in the up(12 o'clock) position.
    3. Coat the mating surfaces of the housing and engine with an adhesive type sealer. Position the new gasket on the engine and place the housing on the engine. Tighten the bolts to specifications
