Air will always travell to the hiest point possible,  if thermostat is in hand fill the engine untill it stops bublbling, connect ya hoses back up, run ya car and leave the radiator cap off for a couple of cycles of the thermostat functioning and it's done, just make sure you got enough water in the block before tou start engine, possible to blow a headgasgit, dont even need thermostat, leave it out and have cooler water circulating fulltime thats what i've done to mine never had issues with engine temp after that

2002 silhoutte new tstat,radiator,belts and hoses runs hot no water at bleeder valve water pump 2 yrs old


It is running hot because have an air lock in the system. Check that the bleeder valve is not blocked . Take a hose off that is high up and run the engine until water comes out . Replace the hose and check for water in the radiator. Open the heater system to help bleed out the air.. If that fails take it to a radiator s\hop and have them pressure bleed it.

I have a 2000 Dodge Durango 5.2L that recently overheated. I replaced the old radiator (had a crack) with a new 4.7L...she still overheats. I viewed that the cooling fan wasn't spinning...I chec


check for low coolant level make sure coolant system been bleed from air.make radiator full coolant and coolant reservoir on the full cold mark.if all is good the cooling fan relay could be bad or the engine coolant temperature sensor could be faulty.

ENGINE WAS RUNNING HOT AND WHEN I CHECKED UNDER THE HOOD THE LOWER RADIATOR HOSE WAS COLAPSED


A collapsed hose will restrict (or completely block) water flow, causing a overheating condition. Before you do anything else, replace the hose. Some aftermarket hoses are available with a wound steel coil that will prevent a hose from collapsing.

Good time to replace all the hoses and thermostat. If I were you, I'd also flush the cooling system while I was at it. Probably wouldn't be a bad idea to take a look at your serpentine (or "v") belt to.

If your particular vehicle has air bleed ports, be sure to properly bleed all air from the system when refilling with coolant. Usually the bleed ports will at or near the point of attachment of both the upper and lower radiator hoses to the engine block.

Good luck!

I Suspect that you have AIR in your COOLING SYSTEM Fallow Procedures BELOW to Insure there is NO AIR IN COOLING SYSTEM


Draining and Filling Cooling System

Draining Procedure

Important: Do NOT add any engine coolant supplement sealant pellets to the cooling system. Drain and refill the engine cooling system every 5 years or 240,000 km, (150,000 mi) , whichever occurs first.

  1. Park the vehicle on a level surface.
  2. Remove and clean the coolant recovery reservoir.
Caution: Refer to Radiator Cap Removal Caution in Service Precautions.

  1. Remove the radiator cap when the engine is cool:
3.1. Slowly rotate the cap counterclockwise to the detention tab. Do not press down while rotating pressure cap. 3.2. Wait until any residual pressure, indicated by a hissing sound, is relieved. 3.3. After all hissing stops, press down on the radiator cap and rotate the cap counterclockwise in order to remove the cap.
Important: Recover and store used coolant in a used coolant holding tank and submit the used coolant for recycling on a regular basis. Do NOT pour used coolant down the drain. Ethylene glycol antifreeze is very toxic. Disposing of ethylene glycol into the sewer system or ground water is both illegal and ecologically unsound.

  1. Place a drain pan under the radiator drain valve in order to collect all of the used coolant.
  2. Open the radiator drain valve located at the bottom of the radiator tank. If only partial cooling system draining is required, drain enough coolant to perform the procedure.
  3. Open the air bleed valve on the thermostat housing 2 full turns
    1. Open the air bleed valve above coolant pump 2 full turns.
    2. Place a drain pan under the engine block drains in order to collect the used coolant.Important: Allow the coolant to drain completely.

      1. Remove both of the engine block drains.
        • The front left engine block drain is located between the starter motor and the engine oil filter.
        • The rear right engine block drain is located near the crankshaft position sensor.
      Filling Procedure
      Reinstall the engine block drains
    3. Close the radiator drain valve,
      1. Install the coolant recovery reservoir. Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL coolant. If Coolant other than DEX-COOL or HAVOLINE DEX-COOL is added to the system the engine coolant will require change sooner; at 50,000 km (30,000 mi) or 24 months.
      2. Slowly add a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water to the radiator until the coolant level is at the base of the radiator fill neck.
      3. Wait for 2 minutes and reinspect the level of the coolant in the radiator. If necessary, add coolant to the radiator until the coolant level is at the base of the radiator fill neck.
      4. Install the radiator cap.Ensure that the radiator cap arrow points toward the radiator overflow tubeImportant: The air bleed valves are brass. Do NOT over-tighten the air bleed valves.

        1. Close the air bleed valve above the coolant pump.
          1. Close the air bleed valve on the thermostat housing.
          2. Fill the coolant reservoir with a 50/50 mixture of GM Goodwrench DEX-COOL or HAVOLINE DEX-COOL and clean, drinkable water. Caution: Refer to Radiator Cap Removal Caution in Service Precautions. Important: If the coolant temperature indicator turns ON, turn the engine OFF immediately and allow the engine to cool. Do NOT remove the radiator cap.
          3. Start the engine and allow the engine cooling fan to cycle on and off 3 times. If the low coolant indicator does not turn OFF and the coolant level is above the Full Cold mark on the coolant recovery reservoir, refer to Engine Coolant Temperature Gage Inaccurate or Inoperative.
          4. Turn off the ignition.
          5. Allow the engine to cool.
          6. Ensure that the engine coolant concentration is sufficient.

1990 Subaru Liberty Overheats


Hi,

I had the same problem with my 1993 Liberty LX. Remove the thermostat (located inside bottom radiator hose engine connection - take the connection off and thermostat is inside). Reassemble (minus thermostat), reconnect bottom hose. Slowly (very, very slowly) refill the radiator and remove the bleed plug ( located beside the top hose connection to the radiator - a black square plug with a phillips head cross in the middle). When the radiator is full and clear water (no air bubbles) is coming out of the bleed point, replace the bleed plug and then the radiator cap.

Run the engine for five minutes (approx) or until normal engine temperature is reached. Allow the engine to cool down and recheck the water level - fill if necessary ensuring that the bleed plug is open and clear water is coming out of that point. Replace Bleed plug and then radiator cap. Run engine for five minutes (approx) and then test dive. If the engine overheats keep filling the radiator until there are no air bubbles coming from out of the bleed point.

This fixed my overheating problem. Good luck and safe motoring.

these cars have relays for the fans, replace relays and the fuses. if still dnt work, replace the temperature sensor. make sure u check the wiring, it may just b a loose wire.
