REMOVAL & INSTALLATION NOTE: It is a good practice to check the operation of a new thermostat before it is installed in an engine. Place the thermostat in a pan of boiling water. If it does not open more than 1?4 in. (6mm), do not install it in the engine. 4.9L Engine Fig. 1: Thermostat location - 4.9L engine where is the thermostat located on a f350, 460 - 84923045.gif

  1. Drain the cooling system below the level of the coolant outlet housing. Use the petcock valve at the bottom of the radiator to drain the system. It is not necessary to remove any of the hoses. 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.
  2. Remove the coolant outlet housing retaining bolts and slide the housing with the hose attached to one side.
  3. Remove the thermostat and gasket from the cylinder head and clean both mating surfaces.
  4. To install the thermostat, coat a new gasket with water resistant sealer and position it on the outlet of the engine. The gasket must be in place before the thermostat is installed.
  5. Install the thermostat with the bridge (opposite end of the spring) inside the elbow connection.
  6. Position the elbow connection onto the mounting surface of the outlet, so that the thermostat flange is resting on the gasket and install the retaining bolts. Tighten the bolts to 15 ft. lbs. (20 Nm).
  7. Fill the radiator and operate the engine until it reaches operating temperature. Check the coolant level and adjust if necessary.

  2. Disconnect the bypass hoses at the water pump and intake manifold.
  3. Remove the bypass tube.
  4. Remove the coolant outlet housing retaining bolts, bend the hose and lift the housing with the hose attached to one side.
  5. Remove the thermostat and gasket from the intake manifold and clean both mating surfaces. To install:
  6. For 5.0L and 5.8L engines, coat a new gasket with water resistant sealer and position it on the outlet of the engine. The gasket must be in place before the thermostat is installed. Install the thermostat with the bridge (opposite end of the spring) inside the elbow connection and the thermostat flange positioned in the recess in the manifold.
  7. For the 7.5L engine, install the thermostat in the recess, then coat the gasket with a water resistant sealer and position the gasket on top of the thermostat.
  8. Position the elbow connection onto the mounting surface of the outlet. Tighten the bolts to 18 ft. lbs. (24 Nm) on the 5.0L and 5.8L engines; 28 ft. lbs. (38 Nm) on the 7.5L engine.
  9. Install the bypass tube and hoses.
  10. Fill the radiator and operate the engine until it reaches operating temperature. Check the coolant level and adjust if necessary.
6.9L and 7.3L Diesel Engines NOTE: The diesel engine thermostat is on the front side of the intake manifold 1987-93 ENGINES 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. WARNING
The factory specified thermostat does not contain an internal bypass. On these engines, an internal bypass is located in the block. The use of any replacement thermostat other than that meeting the manufacturer's specifications will result in engine overheating! Use only thermostats meeting the specifications of Ford part number E5TZ-8575-C or Navistar International part number 1807945-C1.

Where is the thermostat located


Hi,

Your engine must be cold before removing the thermostat.

Find the location of your thermostat by following the rubber hose located on bottom of your radiator (passenger side) to the point where it attaches to the engine. Remove the two bolts at that location and you'll find your thermostat nestled in there.

Be sure to place a pail under the car to contain the coolant.


Thermostat Operation:

00047_thermostat.jpgThe automotive thermostat is a temperature controlled on and off valve. When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator. This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced driveability, and engine protection. The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the engine run cooler. It will actually run hotter because there isn't a thermostat to slow the coolant flow. This means the coolant doesn't stay in the radiator long enough to dissipate its heat.


All the best

Please tell me where locate the theromostat in


The thermostat is located inside the thermostat housing. To find it follow the upper radiator hose to the engine block.
Depending what size of engine you have the location is different.
The thermostat on this vehicle's (the Envoy & Trailblazer are essentially the same vehicle) In-line 6 cylinder engine is on the driver's side of the engine, below & behind the alternator.
If you have a V8 cylinder engine is in front of engine see the picture. Item 303 thermostat housing, 305 thermostat, and 304 thermostat gasket.

Where is the thermostat located in my 1995 mazda 626


The thermostat is located on the engine block, where the upper radiator hose connects to the engine. You'll see a large elbow-like component that is attached to the engine with 2 bolts.
Just follow that upper radiator hose and you got the location. When you remove that housing (elbow-like component), you'll see the thermostat.
Make sure you note which end of the thermostat is up and which end is down. Don't reverse the install.

Need to change thermostat and cant find it. where is thermostat located


GM Corsica/Beretta 1988-1996 Repair Guide
The thermostat is located inside a housing on the back of the cylinder head. It is not necessary to remove the radiator hose from the thermostat housing when removing the thermostat.

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.
