SOURCE: I need to replace the thermostat for my 2000 Isuzu

remove fuel pump fuse and start car when it dies try to start again, no more spluttering just cranking, the fuel system is now depressurised. you can now disconnect both of the quick disconnect fuel lines at rear lower section of inlet manifold this is hard to get to some access this by removing the EGR valve so you can get your arms down there watch out for sharp edges of manifold. you dont need to take the top section of the inlet manifold off but will need new lower inlet manifold gaskets to haed.once manifold is off block all intake ports with rag or put tape over ports to stop dirt and stuff falling into ports while continuing to work on the coolant pipes below to get to thermostat.undo only 4 long centre bolts and the 4 nuts, one in each corner(no.3 in picture).

Where is the thermostat mounted?

    • 1. Locate the thermostat housing by following the radiator hose from the radiator to the engine block. The metal cover that the hose attaches to is the Tahoe's thermostat housing.

    • 2

      Remove the radiator hose retention clip by manually squeezing the clip tabs together. With the tabs together, pull the hose off the thermostat housing. Drain the fluid from the hose by holding the hose in the air. The fluid will drain back into the radiator.

    • 3

      Remove the thermostat housing by taking off the two bolts with a boxed wrench. Lift the hosing off the engine to expose the thermostat.

    • 4

      Pull the old thermostat out of the Tahoe's intake manifold. Place the new one into the intake manifold with the spring-loaded end inside of the intake.

    • 5

      Replace the old thermostat gasket with a new one. The gasket must remain dry during the installation process.

    • 6

      Place the thermostat housing on top of the thermostat gasket and bolt it into place.

    • 7

      Squeeze the radiator hose retention clip tabs together and slide the hose back onto the thermostat housing. Let go of the tabs to secure the hose into place.

Bad theromostat 3.2 isuzu how to

The thermostat on the 2001 Isuzu Rodeo 3.2L v6 is located on the top of the engine under the upper intake manifold. In order to replace it you will have to depressurize the fuel system by running the engine with the fuel pump fuze removed until the engine dies and then carefully remove the fuel rail and injectors. Then remove the intake manifold which will give you access to the coolant nozzle fixture attached to the top of the engine. The thermostat is in the top of the engine block under the nozzle fixture. Be sure to replace the thermostat with the proper replacement part (may be difficult to find) and put on new gaskets for the intake manifold before replacing it.

Where is the thermostat located in the 06 stratus

  • Find the location where the upper radiator hose connects to the intake manifold of the engine by tracing it from the radiator to thermostat intake housing bolted to the intake.
  • 2 Remove the radiator hose from the thermostat intake housing by loosening the band clamp that secures it into place. With the clamp loosened, pull the hose off the housing.
  • 3 Remove the two bolts that secure the housing to the intake manifold and then lift the housing off the intake.
  • 4 Lift the thermostat out of the intake manifold and place the new thermostat into the hole. The end of the thermostat with the pin protruding from it sticks out of the intake manifold.
  • 5 Lift the thermostat intake housing gasket off the intake manifold and place the new one onto the intake manifold.
  • 6 Place the thermostat intake housing onto the intake manifold and bolt it into place. Reconnect the hose using the band clamp.
  • Six-Cylinder Engines
  • 1 Drive the Dodge onto a set of front-end ramps and secure the parking break. Allow adequate time for the radiator fluid to cool down. Thirty minutes is usually adequate.
  • 2 Loosen the petcock on the lower right hand side of the radiator and drain all of the radiator fluid into a drain pan. Close the petcock once drained.
  • 3 Trace the lower radiator hose to the location where the hose connects to the engine block. The metal housing the hose connects to is the lower thermostat outlet. Remove the hose from the outlet by loosening the band clamp and then by pulling the hose off the outlet. Be careful--some fluid will drain from the hose.
  • 4 Remove the two bolts that secure the thermostat outlet to the engine block and pull the thermostat outlet off the block.
  • 5 Discard the O-ring inside the bottom edge of the thermostat outlet and place a new one into the outlet.
  • 6 Pull the thermostat out of the engine block and replace it with a new one. The end with the pin protruding from it sticks out of the engine block.
  • 7 Place the thermostat outlet onto the engine block and secure it into place. Reattach the lower radiator hose with the band clamp.
  • 8 Open the radiator filler cap located on top of the radiator and fill the radiator with the fluid previously drained from the system.

  • please dont forget to give good rateing thank you

    Change thermostat

    Typically, the thermostat is located under an aluminum fitting where the top radiator hose meets with the engine block or the intake manifold. You need to drain the antifreeze into a container from a valve at the bottom of the radiator so that the level is below the top of the engine block. Save this for reuse or disposal. Then loosen the hose clamp and remove the top hose from where it meets the engine block or manifold. Now, loosen the two or three bolts that hold the aluminum fitting from the engine block or manifold and remove it, revealing the thermostat.

    Pay attention to the orientation of the thermostat. Now, clean up the mating surfaces of the fitting and the manifold. Reinstall using a new thermostat orientated the right way, a new gasket and/or silicone sealer, and then the fitting. Attach the hose, refill the radiator, and test for leaks.

    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.

    • The thermostat is located on the motor block under the three bolt flang that the top rediator hose connects to. Remove the three 10MM bolts and the thermostat can be removed for replacement.

    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.

    Note, removing the upper intake manifold is not necessary when removing lower intake manifold, they are removed as an assembly.
    Disconnect negative battery cable. Drain cooling system. Remove air cleaner assembly and inlet duct. Mark and remove distributor. Remove upper radiator hose at thermostat housing. Disconnect accelerator and cruise control cables. Remove heater hoses from intake manifold. Remove EGR pipe.
    Disconnect fuel lines at rear of engine. Remove AC compressor and set aside(leave hoses connected). Remove canister purge solenoid. Disconnect theSCPI injector, ignition coil, Ignition Control Module, generator,IAC motor, TP sensor, O2 sensor, Exhaust Gas Recirculation valve and Engine Coolant Temperature sensor wiring harness connectors. Remove PCV valve and hose. Remove lower intake manifold bolts. Remove lower intake manifold.
    Always use New O-rings when reconnecting fuel lines at rear of engine. Apply a bead of RTV silicone sealer along the front and rear sealing surfaces of the block.See Fig.6. Install new gaskets and intake manifold on block while RTV is still wet to the touch. Use Threadlock 12345382 or equivalent to lower intake manifold bolts. Tighten lower intake manifold bolts in sequence to specification table. See fig. 7. To complete installation, reverse removal procedure.f52665d.gifabc2b5f.gif
